c5e44d055f Adds support for multiple shading models per material. Each material now has a bit field of which shading models it is using. Shading models for a material are selected through a new Shading Model material expression, which can be connected to the new Shading Model material output pin. This is opt-in by selecting "From Material Expression" in the Shading Model drop down on the material. With no changes, everything should behave like before, and the old workflow is still there. Optimized shader code should be as performant as before if not using more than one shading model.

  MAJOR FEATURES & CHANGES
============================

Change 4073167 by Krzysztof.Narkowicz

	Added subsurface profile for eye shading model.
	#jira none

Change 4073422 by Krzysztof.Narkowicz

	Added dual specular for subsurface profile shading model.
	#jira none

Change 4075278 by Krzysztof.Narkowicz

	Fixed forward reflection/refraction rendering issues, which caused ShaderModels.Material.Refraction to fail.
	#jira none

Change 4084231 by Krzysztof.Narkowicz

	Dual specular - replace lobe spread with two separate roughness multipliers. Default material roughness is now replaced by an average lobe roughness in order to support non dual specular features.
	#jira none

Change 4092798 by Matt.Collins

	Some HDR refactoring.

	Previously the DisplayOutput and ColorGamut were only set in GameUserSettings.
	I added a Sink that checks the HDR enable. If it's toggled we apply the correct DisplayOutput and ColorGamut for the current platform (this way we get good settings even if you toggle via the console). These settings are still exposed via the console and can be set independently if the user wants.

Change 4096954 by Chris.Bunner

	Added ShaderModelID as scene texture option and renamed existing value to ShaderModelColor to better reflect the internal code.

Change 4111285 by Brian.Karis

	Eye shading update.
	Added Iris normal (disabled). Removed wrap. Fixed contact shadows.

Change 4155261 by Krzysztof.Narkowicz

	Planar reflection prefilter - use scene viewport size instead of reflection target size in order to keep filter size constant in screen space. This makes planar reflection filter more stable in case of dynamic resolution.

	#jira none

Change 4167644 by Krzysztof.Narkowicz

	Global shader map is now stored in multiple DDC entries (one per shader filename) instead of keeping everything in a single one. This allows to skip recompilation of unchanged shader files.

Change 4183727 by Yuriy.ODonnell

	Implemented auto-conversion from deferred to DBuffer decals in forward shading mode (when GBuffer is not available).

	Added support for specular and metallic channels for DBuffer decals, based on work by Chris Bunner.
	This requires DBufferC to be expanded from 2 to 4 channels, leading to slight increase in DBuffer bandwidth and memory requirements.

	Appearance of DBuffer decals is affected by this change, as specular and metallic channel values previously hard-coded in DBufferDecalShared.ush.
	Decals were forced to be non-metallic and have specular of 4% (0.5 numeric value). Now the authored decal material values will be used, which matches GBuffer decals.

	Added support for DBuffer decals with emissive component.

	Most decal types can now be automatically converted, with the exception of stain decals. Those are currently approximated as regular translucent decals.

Change 4197684 by laz.matech

	Added a PostProcess Volume test to the map to test that Cinematic Depth of View can be achieved through PPVs as well. Changed the BP_DepthOfFeildPOV asset - I exposed Focus Method so that it can be disabled for the PPV test. Added a second Hair Model head to the InFocusHair test so that it tests in and out of focus hair models (changed the name of the test to FocusHair).

	#jira none

Change 4225614 by Rolando.Caloca

	DR - Enable depth collision particles on Vulkan mobile

Change 4235489 by Uriel.Doyon

	Removed r.DefaultFeature.PointLightUnits and r.DefaultFeature.SpotLightUnits and replaced them by a single r.DefaultFeature.LightUnits which also controls the units of newly placed rect lights.

	#jira UE-59525

Change 4260154 by Mark.Satterthwaite

	Parallelize the creation of Metal archives and libraries when they are broken up into smaller sub-libraries, this should reduce apparent cook time by going wide across threads on the host of the cooker.

Change 4270594 by Brian.Karis

	Fix for textured rect light L pointing away from plane due to approximate diffuse integration.

Change 4273361 by Daniel.Wright

	Particle Cutouts with 8 verts now always use stochastic approach.  Circle textures with > 234 edges in the convex hull were overflowing the uint64 calculation of the total number of combinations, causing an infinite loop.

Change 4309174 by Mark.Satterthwaite

	Graph device utilization from the driver monitor stats - really helps see how well the GPU is being used.

Change 4310121 by Matt.Collins

	Optmizing RemoveUniformBuffersFromSource. Brings it from ~20% to ~1.5% in my testing.

	#jira none

Change 4312960 by Daniel.Wright

	Fix from Stephen Hill for incorrect light grid culling near the near plane

Change 4314169 by Richard.Wallis

	FShaderCache and associated public structures are now marked as deprecated.  All FShaderCache code hooks removed from MetalRHI, OpenGLDrv and engine Launch/Shutdown logic.

	#jira none

Change 4320760 by Arne.Schober

	DR - Remove SV_Coverage from basepass interpolants when running with Masked in early Depth with ForwardShading as otherwise earlyZ will be disabled (as the PS has to run).
	#jira UE-60992

Change 4334607 by Uriel.Doyon

	Added custom overrides to reset ULightComponent::Intensity to default (in FLightComponentDetails).
	Now settings a light Intesity to default resets the brightness to the archetype brightness.
	This handles correctly cases where the intensity units differs between the two objects.
	Also changed FLocalLightComponentDetails so that changing intensity units kepts the same brightness
	(by recomputing the Intensity).

	#jira UE-61401

Change 4336188 by Rolando.Caloca

	DR - Added -ReduceThreadUsage so programs can use less threads (for SCW )

Change 4337967 by Rolando.Caloca

	DR - Remove unused RHISupportsShaderCompression function

  MAJOR FEATURES & CHANGES
============================

Change 3870267 by Arne.Schober

	DR - SafeRelease SRVs that might be hold by the Vertexfactories (maybe due to indirect use in GlobalResources)
	Note that the VFs are not owners of the data, e.g the underlying Buffers might be released before this and this reference counting should be uneccessary

	DR - Fix case where LPV requires SSAO to run but no GBuffer is available in formward mode. In this case we force the behaviour to use the simple AO (as ASyncAO pass)
	#jira UE-42135

Change 4042404 by Jian.Ru

	Fix a race condition when RT is disabled and then re-enabled
	#jira

Change 4042437 by Richard.Wallis

	Mac Localization - Mac now uses FUICommand and NSLOCTEXT to build main menu items.  Don't fetch menu items using name since that could change.  Lookup using ID's.

	Note:
	New CB function binding system in *FStartupApplicationToMacMenuBinder*.  Added to simplify the existing and new CB function binding.

	Update:
	Application menu now also gets an update on runtime langauge changed event.  Other menu's get updated anyway as per runloop updates.

	#jira UE-49526

Change 4042602 by Guillaume.Abadie

	Adds support for alpha channel in DOF.

Change 4042603 by Guillaume.Abadie

	Gates global sampler behind SUPPORTS_INDEPENDENT_SAMPLERS for nicer error messsage on platform that do not support them.

Change 4042671 by Guillaume.Abadie

	Massages DOF's shader code for HLSLCC.

Change 4042772 by Mark.Satterthwaite

	Expose the MTLComputePipelineState's label string.

Change 4043013 by Juan.Canada

	Fixed bounds of skeletal meshes could be inverted (min > max) with negative scaling. That was breaking occlusion tests in some scenes, creating flicking issues.
	#jira UE-49290

Change 4043171 by Rolando.Caloca

	DR - Workaround crash on hlslcc

Change 4043182 by Uriel.Doyon

	Fixed skylight issues when using pre-exposure.
	Improved IndirectIrradiance gbuffer encoding when using pre-exposure.

Change 4043452 by Mark.Satterthwaite

	Extensively refactor the MetalRHI GPU profiling code. There is now a "MetalProfiler Start/Stop/Frames=X" in-game command that will spit out JSON files similar to the platform-agnostic TracingProfiler, but this displays the command-buffer encoding and execution which actually makes sense with Metal where we can't arbitrarily insert requests for time-stamps and breaking command-buffers/encoders is expensive.

Change 4044732 by Richard.Wallis

	Fix for macOs restoring to fullscreen results in render with large black border.  Also tested that is fix doesn't seem to re-introduce UE-51270 (CL 3696161).  There appears to be an edge case that can cause the toogleFullScreen: method to not correctly expand window frame to the full screen size - we end up with a frame size of the previous setting.  Forcing the correct values doesn't fix the issue - the only consistant fix seems to be to re-introduce the - (NSSize)window:(NSWindow *)window willUseFullScreenContentSize:(NSSize)proposedSize delegate method.

	#jira UE-57549

Change 4044741 by Guillaume.Abadie

Change 4045010 by Guillaume.Abadie

	Creates TM-DepthOfField in QAGame to test DOF.

Change 4045417 by Jian.Ru

	Prevent recursive flush
	#jira

Change 4045923 by Mark.Satterthwaite

	Further insulate private plugin usage within MetalRHI.

Change 4046006 by Mark.Satterthwaite

	Simplify dependency on the private module and hope it now builds properly.

Change 4046612 by Mark.Satterthwaite

	Apple A9 introduced support for baseVertex & baseInstance, earlier GPUs don't support it at all. The code was incorrectly compiling shaders assuming they did at given Metal shader standard versions. Instead we always compile mobile shaders assuming they don't support base index & vertex and for dektop shaders we now need an A9 or better GPU for it to work.

	#jira UE-55234

Change 4047504 by Mark.Satterthwaite

	Supress warnings about the missing module when not available or enabled. Also make it work on all Metal platforms.

Change 4048765 by Uriel.Doyon

	Fixed compilation issue from CL 4048308

Change 4048776 by Guillaume.Abadie

	Fixes a static pixel projection regressions in TAA caused by alpha channel support in DOF.

Change 4049059 by Mark.Satterthwaite

	Thread names in the MetalProfiler output and don't load the private module when selecting a device as it isn't useful anymore.

Change 4050290 by Mark.Satterthwaite

	Sort out the timebase for all the different Metal clocks when profiling - everything is now in microseconds and seems to line up! Need to rework all the other timing code similarly - but not in this commit.

Change 4050822 by Mark.Satterthwaite

	Partial custom counter support - still has bugs.

Change 4051210 by Guillaume.Abadie

	Dumps PermutationID of shader when shader compile worker crashes.

Change 4051652 by Guillaume.Abadie

	Optimises DOF's reduce with wave broadcast instrinsics.

Change 4051839 by Mark.Satterthwaite

	Tiny fix to changing custom counters.

Change 4052553 by Guillaume.Abadie

	Implements GATHER_INPUT_LAYOUT_RGB_SEPARATE_COC to save texture bandwidth in gather pass.

Change 4052611 by Guillaume.Abadie

	Fixes a crashes in light shaft.

Change 4052916 by Mark.Satterthwaite

	Extend the Mac & iOS Frame-Pacer API to proivde the target output time and the intended duration so that the MetalProfiler can record the display V-Blank window.

Change 4053111 by Rolando.Caloca

	DR - hlslcc - RequiresNegateDDY()

Change 4053402 by Mark.Satterthwaite

	Add instrumentation for buffer & texture allocation and shader & pipeline compilation to MetalProfiler. Everything that I personally care to track should now be in place but the implementation details are grim so there's still plenty of room for improvement.

Change 4053454 by Mark.Satterthwaite

	More attempts to allow the builders to compile for Mac in such a fashion that the private module's perfectly innocuous headers don't cause an error.

Change 4053765 by Guillaume.Abadie

	Fixes a failure in DOFGather's ShouldCompilePermutation() caused by R11G11B10 change.

	Cherry-picks and reworks experimental AO decal from GDC 2017's The Human Race demo.

	AO decal are on purpose not supported with ASync AO, because the proper way location to do that would be right before whenever a pass use it, but is currently challenging to track down considering the screen space AO buffer is used a by a lot of different passes through the scene texture uniform buffer.

Change 4065215 by Arne.Schober

	DR - Make Clang Happy the standart says: "A variable or non-overloaded function whose name appears as a potentially-evaluated expression is odr-used unless it is an object that satisfies the requirements for appearing in a constant expression (5.19) and the lvalue-to-rvalue conversion (4.1) is immediately applied."
	In English this means that when the reference is taken (or it is passed by reference) the pointers could be compared and therefore needed to be allocated.

Change 4065312 by Guillaume.Abadie

	Fixes D3D12RHI doing a draw indexed indirect behind a DrawPrimitiveIndirect()

Change 4070361 by Guillaume.Abadie

	Merging //UE4/Partner-MGPU to Dev-Rendering (//UE4/Dev-Rendering) at CL 4047519 :
	- Fixed d3derror when resizing the window in multi-gpu.
	- Fixed d3d12 checks when exiting in multi-gpu.
	- Command context containter can now only be used with a single gpu mask. This cleans up passing the mask everywhere.
	- RenderPass now reuse the current GPUMask instead of assuming the view mask. Decoupling furter more the binding.
	- Removed of IRHIComputeContext::GetContextForGPUMask().
	- Removed GPUMask from QueueRenderThreadCommandListSubmit and QueueCommandListSubmit since it is now a member of FRHICommandListBase.
	- FRHICommandListBase::CopyContext() can not change anymore the GPUMask and the target list must have the same GPUMask as the reference one.
	- Command lists now have a GPU mask set at creation time.
	- Support for immediate command list GPU mask.
	- Using the new SCOPED_GPU_MASK where we previously used a new command list on the stack.
	- Refactored most NodeMask naming to GPUMask, and also "const FRHIGPUMask&" to "FRHIGPUMask".
	- Commandline option "-mgpu" is now replaced by "-MaxGPUCount=" and "-PresentGPU="
	- Multi-gpu modes are now controlled through  -mgpumode={ gpu0, gpu1, broadcast, avr, afr }
	- Defines WITH_SLI and WITH_MGPU now control the path to multi-gpu support in the engine.
	- Variable GNumActiveGPUsForRendering is now split in  GNumAlternateFrameRenderingGroups and GNumExplicitGPUsForRendering.

Change 3774677 by Arne.Schober

Change 3809579 by Chris.Bunner

	Back out changelist 3774677.

	#jira UE-53483

Change 3810363 by Mark.Satterthwaite

	More random fixes to mtlpp: most important is the extension to Buffer that allows creation of sub-buffers that are merely views onto a sub-range of the parent. These sub-buffers are valid to use throughout the mtlpp API with two exceptions: they may not be used for visibilityResultsBuffers and Set*BufferOffset functions cannot take this offset into account (as the encoder does not hold onto the buffers and I don't want it to). In the case of Set*BufferOffset the caller has to know what is going on and in the case of visibilityResultsBuffers it'll just assert as it isn't sensible.

	This makes it *much* easier to do things like sub-buffer allocation, though the caller must be aware of the alignment restrictions of their intended usage as they are not possible to enforce. For example, a call to SetVertexBuffer requires an offset alignment must match the alignment of the data-type in the shader for "device" resources, or for "constant" data it must be max(4, sizeof(datatype)) on iOS and 256 on macOS. This should allow for much more tightly packed sub-allocations than earlier approaches, though older drivers (e.g. Mac OS X 10.11) enforce only the coarser "constant" data restriction everywhere.

	rd_route v1.1.1 with attached TPS approval.

	For macOS function interposition which is useful for debugging and the occasional workaround.

Change 3845164 by Mark.Satterthwaite

	Add LLM support for macOS, including tracking of memory allocated in Objective-C. This makes use of runtime method swizzling in the Objective-C runtime and the rd_route library I added for Richard Wallis, which allows for arbitrary runtime function interposition and allows me to hook the custom allocators used in Apple's many Objective-C frameworks on which the whole macOS edifice is built. Objective-C objects are charged to the calling scope as they are too common to impose their own without murdering frame rate.

	We would need a TPS approval for an iOS function interposition library for this to work fully on iOS, if desired in the short term discarding LowLevelFree events that aren't in the map rather than asserting will workaround the problem.

Change 3848533 by Richard.Wallis

	DR - Fix OpenGL overwriting texture samplers on forward renderer

Change 3853945 by Mark.Satterthwaite

	Duplicate #3831616

	Fix the black ground scattering on Metal - we've had issues with the atmospheric fog calculations for a long time - one or more intermediate operations generates different precision on Metal so we end up passing -ve values into sqrt which then generates NaN/INF. For Metal when compiling this file and this file only #define sqrt() to sqrt(abs()) so that we don't see anymore unexpected black in atmospheric rendering. This is far from ideal but I don't want to make abs all inputs into every sqrt because AFAIK this is the only case where we have an issue, and until we to investigate each intermediate calculation that isn't ridiculously, soul-crushingly tedious, it isn't practical to identify the source of the error.

	#jira UE-53720

Change 3853966 by Mark.Satterthwaite

	Duplicate #3835852

	Fix tessellation shaders in Metal with Manual Vertex Fetch enabled:
	- The control points idnex buffer shouldn't collide with anything else.
	- We can't use the optimisation of loading texture width & height from the buffer meta-table in tessellation shaders as the combined stages don't guarantee not to clobber unused buffer slots and screw it up when we use linear textures.

	"When material domain is not needing global clip plane there is no need to generate any code involving it. This does not alter output but removes lot of code at vertex shader and pixel shaders. At least on mobile rendered was actually generating clipping code for ui materials."

Change 3877428 by Krzysztof.Narkowicz

	Merged with tiny tweaks Ansel photography plugin improvements from Adam Moss (GitHub pull request #4426):
	-The free-roaming photography camera has new constraints by default, i.e. it can't pass through walls
	-Photography session can be started and stopped programmatically, e.g. making it possible to bind photography to an alternative hotkey or button combo. This was an often-requested feature.
	-Tweakables and utilities are now exposed through a Blueprint Function Library (rather than direct manipulation of console variables)
	-The Ansel photography session UI now exposes some engine effect tweakables as sliders. For example, if the game is using depth-of-field then sliders are made available to allow the photographer to change the focal depth etc. The developer may suppress this behavior through the Blueprint Function Library.
	-Letterboxing is now removed during multi-part capture, d'oh.
	-Tiled shots are taken at full resolution even if ScreenPercentage < 100
	-SSR is enabled during super-resolution shots since Ansel is now better at hiding any ensuing artifacts
	-Postprocess settings are frozen at session start to avoid discontinuities during photography, i.e. wandering between postprocess volumes when the camera auto-moves for stereo and 360 shots.

Change 3891925 by Yuriy.ODonnell

	Fix/workaround for inconsistent preprocessor definitions for NVAftermath that result in FD3D11DynamicRHI class layout mismatch. NVAftermath support is now enabled by default for Win64.

	NVAftermath is declared as a private dependency in D3D11RHI. It does not automatically propagate to modules that explicitly include private RHI headers (OculusHMD, OSVR, OSVRInput). This results in NV_AFTERMATH being defined while compiling RHI module and not defined when compiling other modules, causing memory corruption at runtime.

	The long-term solution for this and similar issues requires some mechanism for adding transitive module dependencies, so that anyone that depends on D3D11RHI module would automatically also get the NVAftermath. Additionally, private headers should *never* be included directly by external modules.

	The short-term solution is to explicitly add NVAftermath dependency to OculusHMD, OSVR and OSVRInput.

	Additionally, NV_AFTERMATH is no longer forced by D3D11RHIPrivate.h when it's not defined. This allows catching this kind of mismatch in the future through a compiler warning (C4668).

	[Integrate] Scene Textures uniform buffer
	* Base Pass Uniform Buffer now contains a Scene Textures uniform buffer.  Previously the translucent base pass had to check ~40 loose scene texture parameters every draw.
	* FMeshMaterialShader's must now bind PassUniformBuffer and supply a valid pass uniform buffer.  For most passes this is just FSceneTextureUniformParameters.
	* FRendererModule::DrawTileMesh can now cleanly set dummy scene texture resources, just by configuring how the pass uniform buffer is created.
	* Moved scene texture shader functions out of Common, into SceneTexturesCommon which must be manually included by shaders that want to use them
	* Separate Mobile Scene Textures uniform buffer to silo the platform complexities

	Moved DBuffer inputs out of FDeferredPixelShaderParameters and into FOpaqueBasePassUniformParameters

	Removed per-frame material uniform expressions.  GameTime material node with period is now implemented with an fmod in the shader, without the use of MaterialFloat, so that it will happen at full precision.
	* Per-frame expressions were used when the GameTime material node had a period, to do the fmod on the CPU where 32 bit precision is guaranteed, for mobile GPU's where pixel shader precision is sometimes less than 32fp.

	Moved forward shading data into the Base Pass Uniform Buffer
	Removed instanced stereo support for the light cull grid - will have to be reimplemented without changing SRV's per draw

	Fix for black flickering on first paint with weighted material landscape on Mac.  When using AsyncCopyFromBufferToTexture in Metal we put the blit operation on the prologue encoder - however after a draw call using that resource the copy operation should happen after on the current encoder, this keeps the correct order of operations.

	Initial implementation of tracing profiler to show CPU and multiple GPUs on the same timeline. Currently only supported on DX12 platforms.

	Use `TracingProfiler frames=N` console command to trigger a capture of the next N frames. Trace is saved to disk as a JSON file into `Saved/Profiling/Traces` directory.
	Trace file uses Google Tracing format and can be visualized in Chrome built-in profiler (chrome://tracing).

	`r.GPUStatsChildTimesIncluded=1` CVar makes timing scopes hierarchical.
	`TracingProfiler.BufferSize=N` CVar controls the size of the tracing buffer, which may need to be increased for long traces (default is 65k events). Only can be set at startup.

	Ensure that packed globals are reuploaded when the command-encoder is restarted - don't simply invalidate the existing parameters. This properly handles cases where a single logical render-pass is broken into multiple command-encoders and/or command-buffers - otherwise all shaders must reset all parameters each time. When we move between frames we *do* want to perform a full state reset though as previous frame globals are treated as invalid.

Change 3990080 by Mark.Satterthwaite

	Change the way we invalidate the visibility buffer between command-buffers and command-encoders so that on iOS you can reuse the same buffer within the same command-buffer, but not across more than one. The code provides an exception to this rule when running under the MetalRHI validation tools which can break each draw call into its own buffer.

	Fixed crashes inside RemoveSpeedTreeWind() and RemoveSpeedTreeWind_RenderThread().
	FStaticMeshComponentRecreateRenderStateContext didn't flush deferred render updates causing stale RenderData to be left:
	1. Thumbnail manager called SetStaticMesh(nullptr), which added StaticMeshComponent to deferred render updates.
	2. UStaticMesh::Build called FStaticMeshComponentRecreateRenderStateContext and destroyed DenderData, but didn't touch Thumbnail's manager StaticMeshComponent as it was nullptr.

	No video when playing HLS streaming video on Mac.  2 Issues, FPS was zero making duration for video sample buffer nonsense and Video Track dimensions were going to zero on the AVAsset once fully initialized when playing HSL streams.  Now cache relevant details and handle zero frame rate.

	Notes:
	- Caching the frame rate is not as important as we could look it up each time and fix for zero - ignoring that at the moment.
	- Assume we DO NOT want the FrameSize to be the last fetched video frame size from the AvfMediaVideoSampler as I think that is the video quality for streaming video and not the media frame size.
	- Renamed a variable in the AvfMediaVideoSample - was called FrameRate but it was the FrameDuration by that point.

	MetalRHI was allowing uniform buffers to blow away linear texture buffers when the constant buffer has been elided due to dead-code elimination. This problem can manifest without linear textures if the uniform buffer contains both constant data and a resource-table but the shader doesn't use any of the constant data. That's because Metal doesn't separate constant buffers from any other kind of buffer unlike D3D which separates all the slots out - and Metal doesn't provide enough buffers to emulate the D3D arrangement. So far this has only manifested in the MVF + Linear Texture case but a more robust solution will be necessary long term.

	Improved use-after-free detection mechanism and physical memory usage of MallocStomp on Windows.

	MallocStomp on Windows will now reserve virtual address space for every allocation and then commit physical pages only to the valid usable part.
	Physical pages will be unmapped on Free, but virtual address space will not be released and therefore will never be re-used.

	Virtual address space is allocated from the OS in blocks of 1GB and then linearly sub-allocated.
	This reduces VA space usage, as VirtualAlloc returns blocks on 64KB granularity even if we just need 4KB. As a small bonus, this also reduces number of syscalls per allocation.

	This dramatically increases accuracy of use-after-free detection, but consumes significant amount of memory for the OS page table.
	Virtual memory limit for a process on Win10 is 128 TB, which means we can afford to keep virtual memory reserved for a long time.
	Running Infiltrator demo consumes ~700MB of virtual address space per second.

	Additionally, committing physical pages only for the usable part of the entire virtual block reduces physical memory usage by ~30% compared to old behavior,
	which allocated and committed entire block of pages via BinnedAllocFromOS and then marks border page as non-accessible.

	Static analysis warning fix: make sure declaration of Sleep() is consistent between Windows headers and TBB

	The complexity with this particular case is that the warning is generated in synchapi.h, which is included by some Windows headers.
	If a module includes TBB and then Windows platform headers, static analyzer will report this warning.
	Suppressing it would require wrapping all instances of Windows header includes in third-party macros.

	Current pragmatic solution is to modify the Sleep() declaration in TBB header to be consistent with Windows and to report the issue to Intel for a permanent fix.

	[Integrate] Pass Uniform Buffers
	* All pass-constant shader inputs should go into the appropriate pass uniform buffer, instead of being set per-draw
	* Moved many per-draw base pass parameters over to the Base Pass Uniform Buffer
	* Opaque and Translucent base pass shaders have different uniform buffers, which allows compile errors when accessing an invalid resource (eg GBuffer in Opaque), instead of silently falling back to GBlackTexture

	Uniform buffers can now contain nested structs with UNIFORM_MEMBER_STRUCT()
	* This allows composing a uniform buffer at a particular update frequency out of many features, with encapsulation of each feature's parameters in a struct.
	* Eg deferred fog uses FFogUniformParameters, but so does translucency in the base pass, where FFogUniformParameters is reused nested inside the base pass uniform buffer.
	* Resources can now be located anywhere in the uniform buffer.  Padding is inserted to the cbuffer representation to keep memory layouts matching.  In the future the cbuffer could be compacted.

	Copying //Tasks/UE4/Dev-UERNDR-354-mtlpp to Dev-Rendering (//UE4/Dev-Rendering):

	Rewrites MetalRHI in terms of mtlpp, which is a C++ wrapper library built around Metal's Objective-C API that attempts to reduce overheads and eliminate resource lifetime errors.

	Regarding mtlpp:
	- The mtlpp library uses C++ constructor/destructor and smart-pointer style management of Objective-C retain/release calls to prevent over- and under-release problems.
	- To reduce Objective-C overheads the mtlpp library caches the internal C-function that implements the Objective-C selectors for the most commonly used Metal protocol types and calls the function directly - this avoids objc_msgSend which does this look-up dynamically and thus improves CPU performance slightly.
	- Another advantage is that mtlpp provides infrastructure to extend the Metal API slightly to help improve MetalRHI - the two important aspects are mtlpp::CommandBufferFence which provides a consistent CPU<->GPU synchronisation primitive and sub-buffer allocations from mtlpp::Buffer which allow for far superior memory management.
	- Validation functionality is also provided by mtlpp to detect CPU vs. GPU data races and resource lifetime validation - this is expensive and is thus optional and compiled out from Shipping binaries that should be used when performance is most critical. The validation only works between resource modification and *submitted* command-buffers - anything that is being actively encoded on the CPU is ignored and it remains the responsibility of the application to validate the order of operations when encoding.

	Apple Platform:
	- LLM support which tracks Objective-C objects is enabled only on macOS - we don't have the necessary libraries to intercept and override the internal system calls on iOS.

	MetalRHI:
	- All the types are switched over, (mostly) insuling the external API from the horror of Metal and Objective-C.
	- Buffers are now managed quite differently, small buffers are allocated from a magazine allocator that allocates in fixed blocks from a larger parent buffer, intermediate sized buffers are allocated from a simple heap allocator that wraps a larger buffer and anything of reasonable size (>2Mb) will use the pooled allocator. This *radically* reduces the number of buffer resources, by as much as a factor of 10, because they are now sub-allocated without the need to use MTLHeap or MTLFence so they are performance equivalent to the existing implementation on the GPU and much faster on the CPU. Total memory use is approximately the same.
	- Vertex & index buffer management has been updated to reflect changes in the management and to avoid reallocating buffers which provide a Linear Texture (for SRVs) unless strictly necessary. This ensures that even in cases where a dynamic buffer is updated multiple times in a frame it will still work acceptably well.
	- The Metal ring-buffer implementation is completely different again, this time it can use Managed memory on macOS which allows for much better performance on eGPUs which will be more and more important for Mac.
	- Everyone that needs to wait on a command-buffer fence (rather than a command-buffer itself) now use mtlpp::CommandBufferFence, which prevents race conditions between the different command-buffer handlers (which sometimes execute out of order).
	- LLM tracking should now report the same data as the MetalRHI stats group for buffer & texture allocations - there is no segmentation for Vertex/index/Structured/Uniform allocations in Metal so these numbers are going to be wrong and will need to be rethought.
	- What will be unseen are the number of small but important resource usage fixes that avoid stale resources from being bound to the device after the point at which they become invalid. This should eliminate a class of errors where the GPU uses a resource pointer that is modified by the CPU and was necessary to satisfy the new mtlpp validation code.

	Other:
	- Remove the Metal focused workarounds from the ClothBuffer resource binding and related vertex-buffer SRV - these were put in when MetalRHI/MetalShaderFormat couldn't handle float->uint conversions correctly and they should now.
	- Fix a validation error caused by trying to render a 0-sized scissor rect which is invalid in Metal and simply pointless elsewhere.
	- Consistency of disabling the Manual Vertex Fetch behaviour in shaders.

Change 3941865 by Mark.Satterthwaite

	Fix the incorrect landscape rendering and the incorrect render-to-texture from blueprint bugs with MetalRHI.

	- Track outstanding AsyncCopyBufferFromBufferToBuffer operations to identify attempts to modify overlapping ranges within the same prologue command-buffer. This doesn't work and requires that we break the current render-pass and issue on the current command-buffer. A log warning will be emitted  when this occurs.

	- Don't attempt to alias private memory buffers the moment they are released from the RHI resource because that can lead to incorrect sharing of the memory when used by AsyncCopyBufferFromBufferToBuffer.

	#jira UE-53492

Change 3938305 by Mark.Satterthwaite

	For whatever reason moving the buffer initialisation into the prologue command buffer doesn't work - this make absolutely no sense to me. I suspect that this is *merely* moving a render pass boundary around somewhere and forcing raster-state to be reapplied.

	#jira UE-56005

Change 3934892 by Mark.Satterthwaite

	In MetalRHI treat BUF_Volatile buffers as Shared or Managed memory in all circumstances so that multiple updates within a render pass are respected even though this will hurt CPU performance. This fixes GPU particles on macOS. Also push initialisation upload into the async. command buffer to avoid it overwriting a later Lock/Unlock! Only read-back and copy-buffer operations should be on the 'current' command buffer as they need to be inline with all outstanding commands.

	#jira UE-55267

Change 3920519 by Phillip.Kavan

	Fix a regression in which elements would not be initialized when constructing the value assignment for UDS-typed container members in nativized Blueprint C++ code.

	Change summary:
	- Modified FEmitDefaultValueHelper::InnerGenerate() to remove UDS from the list of special cases that avoid calling InitializeStruct() as part of new element construction. Previously the conversion code assumed the compiler would perform value initialization of a nameless temporary, but that is no longer valid in 4.19, as UDS types have been changed to function more like native structs, and as such all converted UDS types will now emit an explicit default ctor which is now used to assign defaults that differ from the zero-initialized value.

	#fix Ensure that we dynamically add HLOD level treeview items whenever they are required, rather than adding a static number of levels according to the worldsettings"

	#jira UE-55619

Change 3920126 by Max.Preussner

	MediaCompositing: Implemented media track for Sequencer

	Copied from Dev-Sequencer

	#jira UE-53974

Change 3920004 by Jack.Porter

	Disable Manual Vertex Fetch SRV creation when MVF is disabled.

	Made a single RHISupportsManualVertexFetch(EShaderPlatform) to control whether to use MVF. The Shader Platform (or alternatively, feature level) is the only thing that can decide whether or not to use MVF because we need to know when we compile the shaders if we're going to do MVF or not. Checking GSupportsResourceView at runtime is useless because the shaders can't change and so if GSupportsResourceView can ever be false for a platform, the shaders need to have been built without it.

	Creating SRVs without using them on mobile is not harmless because several devices don't support formats that are needed.

	#jira UE-54764
	#jira UE-55622

Change 3919069 by Aaron.McLeran

	#jira UE-55718 Fix for playback progress.

	#jira: UE-55531

Change 3915967 by Mark.Satterthwaite

	Place buffer updates into the prologue command-buffer in MetalRHI to avoid breaking the current command-encoder. This improves performance, though the semantics of Metal now differ subtly to other RHI implementations as the buffer updates happen prior to the SetRenderTargets call in the GPU's view of the world.

	#jira UE-54858

	Make compilation manager's skeleton class layout better match the old compilation path's skeleton class layout, fixes a crash when renaming blueprint functions

	#jira UE-55592

Change 3915250 by JeanLuc.Corenthin

	Can't add C++ code to Enterprise projects (when enterprise is installed)

	Root cause: When compiling a C++ project, Datasmith modules are included in the build process (with the wrong path)

	Fix:
	- Added two more Enterprise directories, Plugins and Intermediate, to the Enterprise directories to check against
	- Build the correct path for the Datasmith modules and plugins in FindOrCreateModuleByName. Added check to see if module is under one of the Enterprise directories.
	- Added modules to list of precompiled modeules in UEBuildTargets.AddPrecompiledModules if Engine and Enterprise are 'installed and the module is under Enterprise.

	#jira UEENT-1032

Change 3915240 by Ben.Marsh

	Reduce editor startup times by ~15s on Windows.

	Platform loading code recursively scans every module for dependent DLL modules to load first. Change to make it early-out as soon as it encounters a module which is already in memory (via a call to GetModuleHandle() from ResolveMissingLibraryImportsRecursive). Also use a TSet<> to store set of visited modules rather than an Array.

	Now spends <0.1s total in this function on editor startup.

	(Change looks larger than it is due to moving functions out of WindowsPlatformProcess.h to avoid introducing TSet dependency into this header).

	#jira UE-55642

Change 3914803 by Gil.Gribb

	UE4 - Removed memory track from the lock free list links. This is not safe and will sometimes assert in debug.

	#jira UE-49600

	Adding Calibrate button #jira none

Change 3914599 by Andrew.Rodham

	Sequencer: Sequence template source signatures are now also compared to catch the case where a sub-sequence asset has been saved but not modified

	  - The following sequence of events exposes this issue:
	    - Create a master sequence with a single shot that spawns a cube
	    - Add this sequence to a level and set it to auto-play
	    - Save everything and restart
	    - Resave just the inner shot asset without opening it
	    - PIE
	    - The inner shot never spawns its cube because its template was wiped on save, but its signature never changed. Since the master sequence previously didn't check the template source signature, it ends up trying to evaluate an empty template.

	Fix editor-only default subobjects inherited from a native C++ parent class not being handled correctly during nativized Blueprint class ctor generation.

	Change summary:
	- Modified FEmitDefaultValueHelper::HandleSpecialTypes() to skip editor-only checks for instanced default subobjects. These will have already been created by a native parent class.
	- Modified FEmitDefaultValueHelper::HandleInstancedSubobject() to assert before creating a "dummy" component in place of an editor-only instance if we're not supposed to be creating it.

	UE-55394 iOS crash exiting app during startup movie: SPRINGBOARD, process-exit watchdog transgression

	#jira UE-55394
	#jira UE-52328
	#iOS
	#4.19

	This is a particular case of UE-52328 iOS reporting crash on application exit: SPRINGBOARD, process-exit watchdog transgression

	Found several issues on iOS if the game is forced closed when the startup movie is playing and "Wait for movies to complete" is enabled in Project Settings

	- the game thread is waiting for the movie to complete on game shutdown - more that 5 sec

	- crash on FDefaultGameMoviePlayer::Shutdown if the above is fixed

	- HTTP module no longer has time to wait for the requests to complete.

	[CONSOLE] [^] Added RHI Command List Enqueue Lambda method (merging as edit CL 3879722 from //Fortnite/Main to //UE4/Release-4.19)

	 - Can be used to enqueue arbitrary tasks on the RHI thread from the render thread (similar to how EURC works for GT -> RT tasks), without having to write lots of bolierplate FRHICommand functor classes.
	 - The first overload of EnqueueLambda method will check Bypass() to determine if it should run the lambda immediately or defer to the RHI thread.
	 - This can be overriden via the 2nd overload if you need to check additional things such as IsRunningRHIInSeparateThread.
	 - The function returns true if the lambda was enqueued and deferred to the RHI thread, otherwise false. This can be used to optionally add RHIThreadFences for unlock commands etc.

	Fix/workaround for inconsistent preprocessor definitions for NVAftermath that result in FD3D11DynamicRHI class layout mismatch. NVAftermath support is now enabled by default for Win64.

	NVAftermath is declared as a private dependency in D3D11RHI. It does not automatically propagate to modules that explicitly include private RHI headers (OculusHMD, OSVR, OSVRInput). This results in NV_AFTERMATH being defined while compiling RHI module and not defined when compiling other modules, causing memory corruption at runtime.

	The long-term solution for this and similar issues requires some mechanism for adding transitive module dependencies, so that anyone that depends on D3D11RHI module would automatically also get the NVAftermath. Additionally, private headers should *never* be included directly by external modules.

	The short-term solution is to explicitly add NVAftermath dependency to OculusHMD, OSVR and OSVRInput.

	Additionally, NV_AFTERMATH is no longer forced by D3D11RHIPrivate.h when it's not defined. This allows catching this kind of mismatch in the future through a compiler warning (C4668).

	Perforce Plugin: Removed all calls to methods that would update the P4PASSWD environment variable.  Perforce stores this as plain text so it is not safe and we do not want the editor to be responsible for this being set.  All users should be using ticket based p4 servers for the best security but if they are unable to then they can call p4 passwd on their own to set a slightly better hashed password directly.  They may also log in each time to the editor which prevents any password from being stored

	Sequencer: Fixed overlapping ranges being inserted into the evaluation field during compilation

	  - The issue was that track segments that had been combined with adjacent segments (due to them being identical) would potentially cause a subsequently compiled frame to overlap with a range that had already been inserted into the evaluation field.
	  - The insertion code previously asserted that only minor overlaps were catered for (due to fp rounding errors) and assumed that a supplied range could not entirely contain any other range in the field.
	  - The solution is to supply the insertion time along with the range to know exactly where the data should live in the field, and crop the range to the maximum allowable space between adjacent ranges.

	UAT: Remove code to compile UBT when using UE4Build. It should already be compiled as a dependency of UAT.

	PR #4358: Incredibuild use ShowAgent by default (Contributed by projectgheist)


Change 3822594 by Ben.Marsh

	UAT: Improvements to log file handling.

	- Always create log files in the final location, rather than writing to a temp directory and copying in later.
	- Now supports -Verbose and -VeryVerbose for increasing log verbosity, rather than -Verbose=XXX.
	- Keep a backlog of log output before the log system is initialized, and flush it to the log file once it is.
	- Allow buildmachines to specify the uebp_FinalLogFolder environment variable, which is used to form paths for display. When build machines copy log files elsewhere after UAT finishes (eg. a network share), this allows error messages to display the right location.

Change 3823695 by Ben.Marsh

	UGS: Fix issue where precompiled binaries would not be shown as available for a change until scrolling the last submitted code change into the buffer (other symptoms, like de-focussing the main window would cause it to go back to an unavailable state, since the changes buffer was shrunk).

	Now always queries changes up to the last change for which zipped binaries are available.

Change 3823845 by Ben.Marsh

	UBT: Exclude C# projects for unsupported platforms when generating project files.

Change 3824180 by Ben.Marsh

	GitHub #4399 : Added a CONSTEXPR qualifiers to FVariant::GetType()

	#jira UE-53813

Change 3829189 by Ben.Marsh

	UBT: Now always writes a minimal log file. By default, just contains the regular console output and any reasons why actions are outdated and needed to be executed. UAT directs child UBT instances to output logs into its own log folder, so that build machines can save them off.

Change 3830444 by Steve.Robb

	BuildVersion and ModuleManifest moved to Core, and parsing of these files reimplemented to avoid a JSON library.
	This should be revisited when Core has its own JSON library.

Change 3830718 by Ben.Marsh

	Fix incorrect group name being returned by FStatNameAndInfo::GetGroupName() for stat groups.

	The editor populates the viewport stats list by calling this for every registered stat and stat group (via FLevelViewportCommands::HandleNewStatGroup). The menu entry attempts to show the stat name with STAT_XXX stripped from the start as the menu item label, with the free-form text description as a tooltip.

	For stat groups, the it would previously just return the stat group name as "Groups" (due to the raw naming convention of "//Groups//STATGROUP_Foo//..."). Since this didn't match the expected naming convention in FLevelViewportCommands::HandleNewStat (ie. STAT_XXX or STATGROUP_XXX), it would fail to add it.

	When the first actual stat belonging to that group is added, it would add a menu entry for the group based on that, but the stat description no longer makes sense as a tooltip for the group. As a result, all the editor tooltips were junk.

	#jira UE-53845

Change 3831064 by Ben.Marsh

	Fix log file contention when spawning UBT recursively.

Change 3832654 by Ben.Marsh

	UGS: Fix error panel not being selected when opened, and weird alignment/color issues on it.

Change 3832695 by Ben.Marsh

	UGS: Invert the options in the 'Show Changes' submenu for simplicity.

Change 3833528 by Ben.Marsh

	UAT: Script to rewrite source files with public include paths relative to the 'Public' folder. Usage is: RebasePublicIncludePaths -UpdateDir=<Dir> [-Project=<Dir>] [-Write].

Change 3833543 by Ben.Marsh

	UBT: Allow targets to opt-out of having public include paths added for every dependent module. This reduces the command line length when building a target, which has recently become a problem with larger games (due to Microsoft's compiler embedding the command line into each object file, with a maximum length of 64kb). All engine modules are compiled with this enabled; games may opt into it by setting bLegacyPublicIncludePaths = false; from their .target.cs, as may individual modules.

Change 3834354 by Robert.Manuszewski

	Archetype pointer will now be cached to avoid locking the object tables when acquiring its info. It should also be faster this way regardless of any locks.

	#jira UE-52035

	USE_FORMAT_STRING_TYPE_CHECKING removed from FMsg::Logf and FMsg::Logf_Internal.

Change 3835004 by Ben.Marsh

Change 3835340 by Ben.Marsh

	UBT: Write the previous and new contents of intermediate files to the log if they change. Makes it easier to debug unexpected rebuilds.

Change 3837037 by Ben.Marsh

	UBT: Fix engine modules having inconsistent definitions depending on whether modules are only referenced for their include paths vs being linked into a binary (due to different _API macro).

Change 3837040 by Ben.Marsh

	UBT: Remove code that initializes members in ModuleRules and TargetRules objects before the constructor is run. This is no longer necessary, now that the backwards-compatible default constructors have been removed.

Change 3837247 by Ben.Marsh

	UBT: Remove UELinkerFixups module, now that plugins and precompiled modules do not require hacks to force initialization (since they're linked in as object files).

	Encryption and signing keys are now set via macros expanded from the IMPLEMENT_PRIMARY_GAME_MODULE macro, via project-specific macros added in the TargetRules constructor.

Change 3837262 by Ben.Marsh

	UBT: Set whether a module is an engine module or not via a default value for the rules assembly. All non-program engine and enterprise modules are created with this flag set to true; program targets and modules are now created from a different assembly that sets it to false. This removes hacks from UEBuildModule needed to adjust behavior for different module types based on the directory containing the module.

	Also add a bUseBackwardsCompatibleDefaults flag to the TargetRules class, also initialized to a default value from a setting passed to the RulesAssembly constructor. This controls whether modules created for the target should be configured to allow breaking changes to default settings, and is set to false for all engine targets, and true for all project targets.

Change 3837343 by Ben.Marsh

	UBT: Remove the OverrideExecutableFileExtension target property. Change the only current use for this (the MayaLiveLinkPlugin target) to use a post build step to copy the file instead.

Change 3837356 by Ben.Marsh

	Fix invalid character encodings.

Change 3837727 by Graeme.Thornton

	UnrealPak: KeyGenerator: Only generate prime table when required, not all the time

	UBT: Output warnings and errors when compiling module rules assembly in a way that allows them to be double-clicked in the Visual Studio output window.

Change 3837831 by Graeme.Thornton

	UBT: When parsing crypto settings, always load legacy data first, then allow the new system to override it. Provides the same key backwards compatibility that the editor settings class gives

	UBT: Fix exceptions thrown on a background thread while caching C++ includes not being caught and logged correctly. Now captures exceptions and re-throws on the main thread.

	#jira UE-53996

Change 3839519 by Ben.Marsh

	UBT: Simplify configuring bPrecompile and bUsePrecompile settings for modules. Each rules assembly can now be configured as installed, which defaults the module rules it creates to use precompiled data.

Change 3843790 by Graeme.Thornton

	UnrealPak: Log the size of all encrypted data

Change 3844258 by Ben.Marsh

	Fix plugin compile failure when created via new plugin wizard. Passing -plugin on the command line is unnecessary, and is now reserved for packaging external plugins for the marketplace.

	Also extend the length of time that the error toast stays visible, and don't delete the plugin on failure.

	#jira UE-54157

Change 3845901 by Arciel.Rekman

	Linux: fix crash due to lambda lifetime issues (UE-54040).

	- The lambda goes out of scope in FBufferVisualizationMenuCommands::CreateVisualizationCommands, crashing the editor if compiled with a recent clang (5.0+).

	(Edigrating 3819174 to Dev-Core)

Change 3846439 by Ben.Marsh

	Revert CL 3822742 to always call Process.WaitForExit(). The Android target platform module in the editor spawns ADB.EXE, which inherits the editor's stdout/stderr handles and forks itself. Process.WaitForExit() waits for EOF on those pipes, which never occurs because the forked process never terminates.

	Proper fix is probably to have the engine explicitly duplicate stdout/stderr handles for new pipes to output process, but too risky before copying up to Main.

Change 3816608 by Ben.Marsh

	UBT: Use DirectoryReference objects for all include paths.

Change 3816954 by Ben.Marsh

	UBT: Remove bIncludeDependentLibrariesInLibrary option. This is not widely supported by platform toolchains, and is not used anywhere.

Change 3816986 by Ben.Marsh

	UBT: Remove UEBuildBinaryConfig; UEBuildBinary objects are now just created directly.

Change 3816991 by Ben.Marsh

	UBT: Deprecate PlatformSpecificDynamicallyLoadedModules. We no longer have any special behavior for these modules.

Change 3823090 by Ben.Marsh

	UAT: Improve logging for child UAT instances.

	- Calling RunUAT now requires an identifier for prefixing into the parent log, which is also used to determine the name of the log folder.
	- Stdout is no longer written to its own output file, since it's written to the parent stdout, the parent log file, and the child log file anyway.
	- Log folders for child UAT instances are left intact, rather than being copied to the parent folder. The derived names for the copied names were confusing and hard to read.
	- Output from UAT is no longer returned as a string. It should not be parsed anyway (but may be huge!). ProcessResult now supports running without capturing output.

Change 3826082 by Ben.Marsh

	UBT: Add a check to make sure that all modules that are precompiled are correctly marked to enable it, even if they are part of the build target.

Change 3827025 by Ben.Marsh

	UBT: Move the compile output directory into a property on the module, and explicitly pass it to the toolchain when compiling.

Change 3829927 by James.Hopkin

	Made HTTP interface const correct

Change 3833533 by Ben.Marsh

	Rewrite engine source files to base include paths relative to the "Public" directory. This allows reducing the number of public include paths that have to be added for engine modules.

Change 3835826 by Ben.Marsh

	UBT: Precompiled targets now generate a separate manifest for each precompiled module, rather than adding object files to a library. This fixes issues where object files from static libraries would not be linked into a target if a symbol in them was not referenced.

Change 3835969 by Ben.Marsh

	UBT: Fix cases where text is being written directly to the console rather than via logging functions.

Change 3837777 by Steve.Robb

	Format string type checking added to FOutputDevice::Logf.
	Fixes for those.

  MAJOR FEATURES & CHANGES
============================

Change 3783110 by Thomas.Sarkanen

	Added support for logical negation when copying to array properties in the fast path

	#jira UE-52043 - Anim fast path correctly doesn't handle copying to arrays of bools with logical negation

Change 3783112 by Thomas.Sarkanen

	Fixed not being able to assign/unassign constraint and physical animation profiles from the context menu

	#jira UE-50205 - Constraint cannot be assigned or unassigned from current profile when using "Unassign" from the context menu in the Skeleton Tree and Graph

Change 3783114 by Thomas.Sarkanen

	Asset picker now only reports 'picks' on user interactions

	In Ocean and other projects with lots of animation assets, the asset picker amortizes its filter queries over a number of frames. This causes the list to temporarily not include the currently selected item, which then gets reported to client code as a 'deselection'. To address this (and to maintain backwards compatibility) I've added a new delegate that gives more context for selections to the SAssetPicker, allowing us to not report selections that are 'Direct'.

	#jira UE-46802 - Searching for an animation from the dropdown in persona causes it to instantly close

Change 3783118 by Thomas.Sarkanen

	#jira UE-48120 - Renaming Physics profiles the same as existing Physics profiles switches profiles and is confusing

Change 3783438 by Jurre.deBaare

	Vertex paint fill tool fills all channels

	Correctly return whether a mesh section is shown or not when it has not been edited

	This fixes skeletal->static mesh conversion

Change 3783598 by Thomas.Sarkanen

	Fix multi-convex generastion for skeletal meshes

	Some triangle indices were being missed out of the index buffer, so the mesh that the convex hull was generated from was corrupt. Removing an early-out fixes this.

	#jira UE-52529 - Inaccurate Collision is Generated When Using Multi Convex Hull (PhysicsAsset Editor)

Change 3783615 by Jurre.deBaare

	Add support for running multiple jobs simultaneously on a single builder.

	When running job or agent setup, the --num-slots=X parameter defines the number of steps that can run simultaneously (EC procedures pass in the resource step limit). A lock file is created under the workspace root (D:\Build) and a reservation file is created for the first slot that can be allocated (slot-1, slot-2, etc...). The slot number is used to define the workspace name that should be used.

	PR #3742: Treat RootDirectory the same way as Standardized (Contributed by TroutZhang)


Change 3764058 by Graeme.Thornton

	Generate a .code-workspace file for the current workspace. Allows foreign projects to "mount" the UE4 folder so that the engine tasks are avaible, and all engine source is visible to VSCode for searching purposes

	#jira UE-52359

Change 3764705 by Steve.Robb

	Better handling of whitespace in ImportText_Internal() for set and map properties.
	Containers are now emptied upon import failure, to avoid leaving bad container states (unhashed, partial data).
	Fix to USetProperty's temp buffer size to avoid buffer overruns.
	Duplicate map keys are now skipped during import, same as USetProperty's behavior.

Change 3764731 by Steve.Robb

	Don't re-run UHT if only source files have changed in the same folder as headers.  This was already done for hot reload, but there's no reason why it should be limited to that.

	ThreadSanitizer fix for FStats::GameThreadStatsFrame.

Change 3770567 by Ben.Marsh

	Add a FAnnotatedArchiveFormatter interface which allows querying structural type information that may not be in binary archives.

Change 3770826 by Ben.Marsh

	Move StructuredArchive implementation into Core, so primitive types can implement serialization overloads for it.

Change 3770875 by Steve.Robb

	Redundant UScriptStruct::PostLoad removed, which was causing a race condition in async loading.  This was re-establishing the CppStructOps, but that is unnecessary because native classes cannot change as a result of a load - only BP structs can, and they don't have CppStructOps.

Change 3772167 by Ben.Marsh

	Add a context-free binary formatter that can serialize tagged data. This functions as a lower-overhead binary intermediate format for JSON data.

Change 3772248 by Steve.Robb

	ThreadSanitizer fixes to FMalloc call counters.

Change 3772383 by Ben.Marsh

	Separate archive metadata from FArchive into FArchiveContext, so it can be safely exposed to consumers of FStructuredArchive.

Change 3772942 by Graeme.Thornton

	Add experimental setting to enable in-editor text asset format functionality
	Add "export to text" option into the content browser asset actions context menu

Change 3772955 by Ben.Marsh

	Add a new "stream" compound type to FStructuredArchive, which allows serializing a sequence of elements similarly to an array, but without serializing an explicit size. Allows passing through data to an underlying binary archive without breaking compatibility.

Change 3772963 by Ben.Marsh

	Allow querying record keys and stream lengths from annotated archive formatters, since these archives have markup for field boundaries.

Change 3773010 by Graeme.Thornton

	Added CORE_API to FArchiveFromStructuredArchive
	Gave text asset format experimental option a slightly less random tooltip comment

Change 3773057 by Ben.Marsh

	Add a flag to FArchive to determine whether the archive is text (IsTextFormat()).

	Add support for seeking within FArchiveFromStructuredArchive. For text formats, data is serialized to an in-memory buffer, with names and objects serialized as indices into an array. For non-text formats, data is serialized directly to the underlying archive.

	Also rename FStructuredArchive::TryEnterSlot() to TryEnterField().

Change 3773118 by Steve.Robb

	TSignedIntType and TUnsignedIntType type traits for getting an integer type of a given size.

Change 3773122 by Steve.Robb

	UE4 - Fix rare crash in the pak precacher immediately after unmounting a pak file.

Change 3774426 by Ben.Marsh

	Copy all C# tools to a staging directory before compiling them. This prevents access violations when compiling tools like iPhonePackager that reference DotNETCommon, and ensures we strip NotForLicensees folders out of them all.

	See: https://answers.unrealengine.com/questions/726010/418-will-not-build-from-source.html

Change 3774658 by Ben.Marsh

	Improve error reporting while generating intellisense for project files. Include the name of the target being compiled, and allow project file generation to continue without it.

Change 3775141 by Ben.Marsh

	Always output HTML5 diagnostics at "information" verbosity, to avoid every line being prefixed with "WARNING:" and screwing up the EC postprocessor.

Change 3775459 by Ben.Marsh

Change 3777931 by Graeme.Thornton

	Refactored FArchiveUObjects serialization code into some static helpers
	Added FArchiveUObjectFromStructuredArchive which allows the adaption of a structured archive into an FArchive that supports the extra UObect serialization functions for weak/soft pointers

Change 3777942 by Graeme.Thornton

	Added missing CORE_API to FStructuredArchive::FStream
	Added FStructuredArchive::FSlot insertion operator for char
	Added specialization of TArray<uint8> serializer for structured archives which serializes the contents as one value

Change 3778084 by Graeme.Thornton

	Adding FPackageName::GetTextAssetPackageExtension() to access the file extension we use for text asset files

Change 3778096 by Graeme.Thornton

	UE4 - Fixed a linear search in EDL that caused performance problems for very large maps.

Change 3784503 by Ben.Marsh

	Optimizations for FStructuredArchive:

	* Store the depth explicitly in element objects, to avoid having to loop through the scope stack to find it.
	* Prevent shrinking of arrays when removing elements.
	* Add an inline allocator to the scope and container stacks.

Change 3784700 by Ben.Marsh

	Remove the inline allocator from FStructuredArchive; checking whether the inline or backup allocator is being used is slower than just allocating up-front.

Change 3784989 by Ben.Marsh

	TBA: Add checks in debug builds that key names in maps and records for FStructuredArchive are unique.

Change 3788678 by Ben.Marsh

	Fix compile error due to inability to instantiate TArray<> of forward declared struct. Convert set of key names to an array to avoid including Set.h in public header for FStructuredArchive.

Change 3789353 by Graeme.Thornton

	Removed unused/rotten modes from TextAsset commandlet.
	Used existing "-iterations=n" switch to control a global iteration over the given command. Useful for performance testing.

Change 3789396 by Ben.Marsh

	Move code to validate container keys/sizes into DO_GUARD_SLOW checks, and allocate container metadata instances dynamically to fix problems with references to things not declared in headers that can't be included from StructuredArchive.h

Change 3789772 by Ben.Marsh

	Always strip trailing slashes from the end of paths specified by .build.cs files; they can cause quoted paths to be escaped on the command line.

Change 3790003 by Ben.Marsh

	#jira UE-20357
	#jira UE-52137

Change 3790709 by Steve.Robb

	Better move support for TVariant.
	EVariantTypes switched over to using an enum class to aid debugger visualization.

Change 3791422 by Ben.Marsh

	TBA: Return the type of a field from an annotated archive formatter at the point that we enter it, rather than querying all the time.

Change 3791489 by Graeme.Thornton

	TBA: Change StructuredArchiveFromArchive adapter to use the archive.Open() result directly, now that it's a slot and not a record

Change 3792344 by Ben.Marsh

	Improvements to base64 encoding library.

	* Now supports encoding and decoding with ANSICHAR and WIDECHAR implementations.
	* Added support for decoding base-64 blobs without padding marks.
	* Added support for decoding into pre-allocated buffer.
	* Added constexpr functions for determining the encoded and maximum decoded size of an input buffer.
	* Prevent writes past the end of allocated buffer (no longer need to manually remove padding bytes).

Change 3792949 by Ben.Marsh

	TBA: Rename FAnnotatedArchiveFormatter to FAnnotatedStructuredArchiveFormatter.

	#jira UE-52392

Change 3794413 by Ben.Marsh

	TBA: Remove the element type parameter to SetScope(). It isn't really needed; we can just assume the element ID correctly identifies the item on the stack.

Change 3794731 by Ben.Marsh

	TBA: Optimize creation of stack elements for empty slots in FStructuredArchive. This saves a lot of bookkeeping when serializing a large number of individual fields. Since only one slot can be active at a time (and it only exists temporarily, until we write into it), we can just store the element ID assigned to it in a member variable.

Change 3795081 by Ben.Marsh

	UBT: Move LinuxCommon.cs into Platform/Linux folder.

	UAT: Work around for exception thrown by launching cook with "-platform=Android_ETC1 -targetplatform=Android -cookflavor=ETC1". Anrdoid_ETC1 is not a valid platform (it's a cook platform), and can't be parsed by UAT.

	#jira UE-53232

Change 3799050 by Ben.Marsh

	Make UnrealPak.version files writable for Mac and Linux.

Change 3801012 by Graeme.Thornton

	UGS: Show an in-place error panel when a project fails to open, allowing the user to retry and have their tabs saved instead of creating a modal dialog.

Change 3624590 by Steve.Robb

	AddReferencedObjects now generates a compile error with containers of UObject*s where the UObjectType is forward-declared, as these which won't be added to the reference collector.
	Tidy-up of existing calls to AddReferencedObjects.

Change 3629473 by Ben.Marsh

	Build: Rename the option for embedding source server information in PDB files for installed engine builds.

Change 3632894 by Steve.Robb

	VARARG* macros deprecated and usage replaced with variadic templates.

	Tidy up of existing code which uses it.

Change 3770553 by Ben.Marsh

	Adding structured serialization API to Core/CoreUObject for use with text-based assets.

	* FStructuredArchive abstracts an archive which is made up of compound types (records, arrays, and maps). Values are stored in slots within these types.
	* Records are string -> value dictionaries where the key names can be compiled out in non-editor builds or when WITH_TEXT_ARCHIVE_SUPPORT = 0.
	* Maps are string -> value dictionaries where the key names are present regardless of the build type.
	* Proxy objects are defined to express the context for serialization (FStructuredArchive::FRecord, FStructuredArchive::FArray, FStructuredArchive::FMap, FStructuredArchive::FSlot) which allows basic validation through static typing. These objects act as lightweight handles, and can be cheaply constructed and passed around on the stack. Most serialization to and from the archive is done through these objects.
	* Runtime checks perform additional validation to ensure that serialized data is well formed and written in a forward-only manner, regardless of the underlying archive type.
	* The actual input/output format is determined by a separate interface (FArchiveFormatter). Context validation (always causing matching LeaveArray for every EnterArray, etc...) is done by FStructuredArchive, so implementing these classes is fairly trivial. FArchiveFormatter can be de-virtualized in non-editor builds, where WITH_TEXT_ARCHIVE_SUPPORT = 0.
	* Includes implementations of FArchiveFormatter for binary and JSON formats.

Change 3771105 by Steve.Robb

	Deprecation warnings for PLATFORM_COMPILER_HAS_AUTO_RETURN_TYPES and PLATFORM_COMPILER_HAS_DEFAULTED_FUNCTIONS.
	Fix for incorrect warning formatting on Clang platforms.

Change 3771520 by Steve.Robb

	Start moving Clang-using platforms' pre-setup stuff into a Clang-specific header.

Change 3771564 by Steve.Robb

	More common macros moved to the Clang pre-setup header.

Change 3771613 by Steve.Robb

	EMIT_CUSTOM_WARNING_AT_LINE moved to ClangPlatformCompilerPreSetup.h.

Change 3772881 by Ben.Marsh

	Add support for serializing FName and UObject through FStructuredArchive.

	In order to allow custom linker behavior when serializing objects:

	* The constructor to JSON input formatter now takes a delegate to convert a string object name into a UObject pointer.
	* The constructor to tagged binary formatter takes a delegate to serialize a UObject pointer into any form it chooses (likely an integer index into the import table)

	Object and name types are stored as strings in JSON, using an "Object:" or "Name:" prefix to differentiate them from regular strings. Any strings that already contain one of these prefixes are prepended with a "String:" prefix (as is any string that already has a "String:" prefix).

Change 3772941 by Graeme.Thornton

	Make build work when including StructuredArchive.h from core container types
	Added standard header to new files
	Add structured archive serializer for TArray
	Fix bug in structured archive where containers weren't being popped from the scope stack

Change 3772972 by Ben.Marsh

	Add an adapter which presents a legacy FArchive interface to a FStructuredArchive slot.

	Data is serialized into this slot as a stream of elements; raw data is buffered up into fixed size chunks, names and objects are serialized separately.

	When used with FBinaryArchiveFormatter, this should result in all data being passed through to the underlying archive in a backwards compatible way, wiith no additional bookkeeping fields.

Change 3773006 by Ben.Marsh

	Rename FStructuredArchive::FRecord::EnterSlot() to EnterField().

Change 3773013 by Steve.Robb

	bUseInlining target rule added to UnrealBuildTool, which defaults to true, to allow inlining to be disabled for debugging purposes.

Change 3774499 by Ben.Marsh

	Minor fixes for FStructuredArchive related classes:

	* Text-based archive formats are now compiled out when WITH_TEXT_ARCHIVE_SUPPORT = 0.
	* Fixed issue with FTaggedBinaryArchiveFormatter state becoming corrupted when looking ahead at field types.
	* FArchiveFieldName constructor is now explicit, to fix cases where strings were being passed directly to serialize functions.

Change 3774600 by Ben.Marsh

	Add CopyFormattedData() function, which can copy data from one formatter to another. Add a test case to SerializationAPI that converts from data -> JSON -> binary -> JSON -> data.

	This function can be used to implement a generic visitor pattern, by implementing a FArchiveFormatter which receives the deserialized data.

Change 3789721 by Ben.Marsh

	TBA: Split FTaggedBinaryArchiveFormatter into separate classes for reading and writing.

Change 3789920 by Ben.Marsh

	TBA: Support automatic coercion between any numeric types in tagged binary archives. Also report the smallest type that can contain a value, rather than just in32/double.

	#jira UECORE-364

Change 3789982 by Ben.Marsh

	TBA: Change FStructuredArchive::Open() to return a slot, rather than a record, to make it easier to implement a raw FArchive adapter.

Change 3792466 by Ben.Marsh

	TBA: Better handling of raw data in text based assets. Short sequences of binary data are Base64 encoded as a single string. Longer sequences are stored as an array of Base64 encoded lines, push a SHA1 hash to detect cases where the data was merged incorrectly.

	In order to allow inference of the correct type for a field, other fields called "Base64" will be escaped to "_Base64", and any field beginning with "_" will have an additional underscore inserted. Reading files back in reverses these transformations.

Change 3792935 by Ben.Marsh

	TBA: Rename FArchiveFormatter to FStructuredArchiveFormatter for consistency with FStructuredArchive.

Change 3795100 by Ben.Marsh

	UBT: Rename the ModuleRules Definitions property to PublicDefinitions, to make its semantics clearer.

Change 3795106 by Ben.Marsh

	Replace all internal usages of ModuleRules.Definitions, and replace it with ModuleRules.PublicDefinitions.

Change 3796275 by Ben.Marsh

	Fix paths to Version.h includes from resource files.

Change 3800683 by Josh.Engebretson

	Remove WER from Mac and Linux crash reports in favor of unified runtime-xml format
	#jira UE-50073

Change 3803545 by Steve.Robb

	TWeakObjPtr const-dropping assignment fix.
	Fixes to change.

	DR - vk - Fix validation issue

Change 3697488 by Richard.Wallis

	Fix for Mac editor session no longer accurately tracking Mouse location after moving between Desktops in Mission Control on 10.12.6.  Problem stems from the extra call to update the slate cached window position in mouse move while dragging, which is itself is a hack but apparently this is needed as we don't get window position updates on Mac while dragging (although I couldn't see any -ve side effects without it) then the OS (in 10.12.6) doesn't always push out a final window did move notificaiton when changing desktops which leaves the window according to slate incorrectly positoned to it's frame.

	Solution is to either remove the mouse-move-while-drag window position hack or add a final window position update to the mouse-up event while dragging - this change is the latter.

	#jira UE-37553

Change 3697501 by Richard.Wallis

	Move audio processing over to audio bus tap.  Currently on Mac Media audio playback uses OS media player mixer rather than Engine as existing implemtation, using AVAssetReader, now suffers from poor performance with new Media Framework.  This audio tap version replaces that asset reader implementation but also suffers from bad quality audio hence is still disabled at the top of AvfMediaTracks.cpp.

	Original Code Review Description:

	Convert Mac to Play audio through the engine MediaFramework API rather than using AVMediaPlayer.  This is the Mac implementation only - this should work ok on iOS but unable to test due to missing audio type implementation (throws error "Init Buffer on unsupported sound type name = Synth type = 5"), as such is only enabled for Mac.  There maybe some extra tweaks required for iOS on app backgrounding etc if this feature is enabled.

	- Stuttering Audio Performace issue investiagation:  Re-Tested this implementation against [now fixed] current Mac implementation which was working fine last year and that implementation now has the same audio output quality (performance) issues as this one.  Basic investigation seems to point to somewhere in the engine audio handing.  When poor audio is heard the FMediaAudioResampler::Generate() function is dequeing an IMediaAudioSample sample buffer and the audio sample queue usually has 50-100 of these IMediaAudioSample buffers waiting in the queue.  I think the AvfMedia playback system is providing the sample buffers in good time but they are not getting consumed "fast" enough.  This under consuming also occurs if I force the Core Audio - Audio Unit mixer to use 48000 samples/sec.

	#jira UEPLAT-1677

Change 3697517 by Richard.Wallis

	XCode 9.0 extra nullability specifiers required.

Change 3697537 by Richard.Wallis

	Back out revision 23 from //UE4/Dev-Rendering/Engine/Plugins/Media/AvfMedia/Source/AvfMedia/Private/Player/AvfMediaTracks.cpp

Change 3697670 by Rolando.Caloca

Change 3699969 by Rolando.Caloca

	DR - vk - Change dump layer location so it prints out validation ids

Change 3700356 by Guillaume.Abadie

	Implements secondary screen percentage to be able to do TAA upsample followed spatial upscale so that the editor viewport still have same TAA upsample screen percentage range to test the content with no matter monitor's DPI.

Change 3701105 by Guillaume.Abadie

	Ignore per view automatic mip bias on texture type other than 2d textures.

	#jira UE-51396

Change 3702297 by Richard.Wallis

	Mac compile fix for nullable specifier.  Looks like Obj class using the C++ class also needs this otherwise it throws.  Seems to be some kind of xcode/compiler caching bug with this stuff as it'll report the error once then on subsequent compiles say everything is ok.

	#jira UE-51386

Change 3702357 by Richard.Wallis

	Mac nullability compile fix - again.  Looks like I fell foul of that xcode compile caching!
	#jira UE-51386

Change 3702424 by Guillaume.Abadie

	Fixes planar reflection from drowing themselves in their own FSceneRenderer in forward shading.

	#jira UE-51395

Change 3702464 by Guillaume.Abadie

	Fixes wrong viewport to buffer conversion of the distortion.

	#jira UE-51406

	DR - vk - Fix map for depth surfaces

Change 3704739 by Rolando.Caloca

	DR - Debug label on D3D11 UAVs
	- Validate when running -d3debug

Change 3705000 by Chris.Bunner

	Skip compiling opacity and opacity mask inputs on opaque surface materials. Previously the code was always added to the shader, sometimes we force opaque materials down a masked path which then calls the dormant code unintentionally. A safer fix for UE-48254.
	Partially reverted previous fix in CL 3608303 which removed a material instance optimization caching the overridden base properties.

Change 3706065 by Guillaume.Abadie

	Does some renaming for primary screen percentage, and move the primary screen percentage method selection from dynamic resolution driver to FSceneView.

Change 3706464 by Chris.Bunner

	Fixed material property translate overrides that were generating code in the wrong entry.
	Fixed conditions  in If material expression GetInputType and IsMA check.

	#jira UE-51368

Change 3706641 by Chris.Bunner

	Missing "break" in switch statement (which unfortunately needs another bump to resolve).

Change 3706642 by Guillaume.Abadie

	Fixes assertion failure when r.TemporalAA.EnableUpscale = 1

Change 3706650 by Gil.Gribb

	UE4 - UE4 - Changes from intel. Increase number of worker threads on Windows to if hyperthreads (hyperthreads √ 2) else cores √ 1 up to a max of 22 workers. Increase MAX_THREADS multiplier per bank from 22 to 26. Intel VTune ITT event annotations. Wrapped in same function as your existing CPU events and enabled with √vtune. Optimize NV cloth by consuming FVector instead of FVector4 out of the solver. Vertex buffers were using FVector all along. ~15% improvement. Optimize cloth copy to vertex buffer by adding prefetch (similar to how bones are already done). Move local to world cloth transform from CPU to GPU. When simulating lots of vertices game thread was becoming bottleneck doing matrix multiply. Add your TaskGraph task switch latency test code.

Change 3706733 by Daniel.Wright

	Print Embree Build time

Change 3706841 by Daniel.Wright

	EmbreeFilterFunc4 now handles masked out intersections properly

	DR - vk - Compile fix

Change 3710454 by Mark.Satterthwaite

	Refactor the way we compile Buffer<> & RWBuffer<> types for Metal so that we can support the type-conversion semantics of HLSL/D3D.
	- Buffer<> types are converted to Linear Textures unless the internal type is 3-compnent or the STRONG_TYPE macro is added as a type-qualifier. Linear Textures require an MTLTexture "view" object be created around the MTLBuffer which is the backing-store and it is typically best if that buffer is marked as Private (GPU-only) memory, reading from this in the shader then uses the texture-fetch hardware to perform the format conversion on load.
	- RWBuffer<> & 3-compnent Buffer<> types are converted to use template functions to load/store - the implementation of which will read the format from the BufferSizes meta-table and determine which type-conversion to apply. Function-constants are used to specialise the shader where feasible to reduce branch costs (function-constants are a Metal feature that allow efficient runtime recompilation of bytecode shaders).
	- Buffer<> & RWBuffer<> types where the STRONG_TYPE macro is added as a type-qualifier (only does something on Metal, everywhere else it is #define'd away) are compiled as "raw" Metal buffers of the inner-type (e.g. float4 for Buffer<float4>) and the MetalRHI runtime will enforce that only SRVs/UAVs of the proper format are bound to it. This is necessary in a couple of cases (BoneMatrices, NumCulledLightsGrid, CulledLightDataGrid & ForwardLocalLightBuffer buffers) which are used in a larger number of shaders as Linear Textures have poorer performance than Buffer<>/RWBuffer<>.
	- Most of the complications to generating subtly different Metal code for different OS/device combinations have been factored out into ue4_stdlib.metal which acts as an extension to the Metal shader standard-library and helps simplify the MetalBackend code - particularly helpful for Buffer<>/RWBuffer<> but also texturecube_array and the SM6 wave-related intrinsics.
	- Reverted some of the awkward Metal-specific changes Richard.Wallis & Arne had to make to the high-level shaders as they aren't necessary anymore.
	- Made the existing Metal-specific changes to use uint32 for all light-grid injection buffers apply to all Metal platforms again (I had hoped that it would not be necessary anymore, but it is much faster this way).
	- STRONG_TYPE is actually hlslcc's "invariant" keyword applied as a type-qualifier to a Buffer<>/RWBuffer<> type - only valid when using Metal which exports this through ILanguageSpec and #define'd out for everyone else.
	- Old versions of iOS (anything earlier than iOS 10.3) won't be able to use this new code, so every buffer will be treated as "raw" and the MetalRHI will now properly report when something goes awry rather than it leading to mysterious rendering errors and crashes.

Change 3710456 by Mark.Satterthwaite

	Fix the Eddie workset project generator so that Enterprise projects don't get mixed in with regular projects at the top-level because of the way Eddie combines workset groups.

Change 3710457 by Mark.Satterthwaite

	DX11 texture formats for Mac Metal please!

Change 3710480 by Mark.Satterthwaite

	Permit RHI thread and parallel execution in Mac -game mode again.

Change 3710522 by Mark.Satterthwaite

	MSVC type-mismatch error fixes.

Change 3710580 by Mark.Satterthwaite

	Alright then - if I can't use the C++11 extended string semantics I'll have to use "xxd -i" to generate a hex-dump include header from ue4_stdlib.metal instead. This can only be updated from a machine with access to the POSIX xxd command (Mac & Linux, possibly the new Linux sub-system for Win10).

Change 3710616 by Mark.Satterthwaite

	Missing file.

Change 3712972 by Guillaume.Abadie

	Fixes Circle DOF's negative alpha channel getting clamped to 0 in TAA pass.

Change 3712979 by Guillaume.Abadie

	Fixes wrong RT reallocation when doing TAA upsample in editor viewports with secondary upscale.

Change 3713406 by Mark.Satterthwaite

	Use GPU morph targets on Mac - the necessary buffer conversions will always be available there. For iOS it can only be supported if iOS 10 is the minimum OS & Metal standard so leave that on the CPU path for now.

Change 3713494 by Richard.Wallis

	Fix for hitch when PIE unloading sublevel.  PerformReachabilityAnalysisOnObjects is spawing multiple threads in Editor builds as there is an extra code path that results in Critical Section locking within a singleton type static object - this is a bottle neck for multiple threads.  However they all just need to read the data not change it.  Replaced FScopeLock with a Read/Write version allowing these threads to all take a read lock at the same time to reduce contention.

	Changed the FUObjectAnnotationDense implementation only - left the sparse implementation alone as its not currently affecting this - although we could proactivly change that too.

	Also tested again repro in linked bug UE-24711.

	#jira UE-40533

Change 3713612 by Mark.Satterthwaite

	Integrate LPV_STORE_INDEX_IN_HEAD_BUFFER related changes from //depot/Partners/Microsoft/UE4-MS/Engine-Fable @ 2954744

	This should make Light Propagation Volumes potentially viable on non-Microsoft platforms.

Change 3713623 by Mark.Satterthwaite

	Implement ByteAddressBuffer/RWByteAddressBuffer in hlslcc in a similar manner to StructuredBuffer/RWStructuredBuffer so that the backends don't need too much modification. Implement the necessary changes into MetalBackend to make this work for Metal.

	Load/Store{+2,3,4} & Atomics are supported. Counter operations are not supported and aren't likely to be.

Change 3713636 by Mark.Satterthwaite

	Enable LPVs for Mac Metal.
	- Rework some multi-dimensional arrays & array-index dependent HLSL code that hlslcc simply can't cope with, the mesa-glsl compiler core is only capable of dealing with 1 dimensional arrays and array-indexing can't itself be directly dependent on the result of an array-index operation.
	- MetalRHI needs to ignore any SetRenderTargets call that binds nothing at all as you must bind at least one target (UAV, RT, Depth/Stencil) for it to be able to do anything sensible.
	- Turn on LPVs for Metal as it works now.

Change 3714049 by Guillaume.Abadie

	Do not set screen percentage method to TAA upsample when anti aliasing method is not TAA even if there is automatic fallback in the renderer.

Change 3714306 by Guillaume.Abadie

	Fixes assertion failure in dynamic resolution state proxy with GPU busy time queries.

Change 3714714 by Mark.Satterthwaite

	Tweak Metal GPU identification so that it works with eGPU boxes and protoype hardware - these changes only apply to macOS 10.13 so the system as a whole remains.

Change 3716104 by Mark.Satterthwaite

	Fix 10.12/Xcode 8 compile errors from the build-farm which is still split until Fortnite can update.

Change 3716120 by Mark.Satterthwaite

	Silence static-analysis.

Change 3716158 by Guillaume.Abadie

	Rewrites editor primitive compositing to support TAA upsample.

	This takes the oportunity to remove the manual depth testing in base pass pixel shader of editor primitives.

Change 3716271 by Daniel.Wright

	Lightmass correctness fixes
	* After these changes, point, spot, directional and sky lights closely match reference renderer Mitsuba after light unit conversions
	* Photon density trimming intended for direct photons was affecting indirect photons as well.  This caused high noise for point / spot lights with a large attenuation radius.  Indirect photon density even for small lights is 5x with this change, which improves 2nd bounce quality.
	* Removed legacy fudge factor on point / spot light photon energy
	* Spotlights no longer emit based on indirect photon paths.  Fixes excessive photon energy from spot lights as they were emitting outside of the cone.
	* Fixed photons computing one more bounce than requested.
	* Added an option to use the Radiosity solver for all multibounce, replacing photons.  Useful as a reference but generally too much noise indoors.
	* Fixed visualization of photons without final gather

Change 3716434 by Mark.Satterthwaite

	Backout the remaining change from 3632041 that is no longer necessary - this was the last of the 4.18 Metal workarounds.

Change 3716491 by Chris.Bunner

	Fixing up an edge-case on a recent optimization.

Change 3716611 by Guillaume.Abadie

	#jira UE-51580

Change 3717111 by Arne.Schober

	Fixing nomalization of Morph Tangents https://udn.unrealengine.com/questions/392462/
	Also implemanted batching of the dispatches which should help worst case perfomance where dispatches become too small.
	CalculateInverseAccumulatedWeights is not cheap and proably should be moved onto a task thread that runs as soon as the input weights are ready.

Change 3717127 by Mark.Satterthwaite

	Fix a mismerge from the reversion of 3632041 - part of the modified code had been moved into another file and I didn't initially notice.

Change 3717178 by Mark.Satterthwaite

	Remove useless copy-pasted expressions from glsl_type::GetByteAddressBufferInstance & force MetalBackend to relink. Apparently the previous Mac libs were mysteriously broken.

	#jira UE-51583

Change 3717476 by Marcus.Wassmer

	Fix PS4 compile.  funciton local statics not allowed on PSSL
	Also enabled the new atomics method for LPVs for all platforms

Change 3717502 by Arne.Schober

	DR - Compiletime option for compressed ruleset (0.02ms perf gain on PS4 and disabled by default as it limits array size to 2million entries)

Change 3717601 by Arne.Schober

	DR - Move cycle counter into more meaningfull locations.

Change 3718054 by Guillaume.Abadie

	Removes unecessary check() failure on secondary upscale that fires when testing raw output screen percentage method.

Change 3718066 by Guillaume.Abadie

	Reland: Rewrites editor primitive compositing to support TAA upsample.

	This takes the oportunity to remove the manual depth testing in base pass pixel shader of editor primitives.

Change 3718589 by Mark.Satterthwaite

	Console-variable to enable and disable Manual-Vertex-Fetch for Metal and fix the internal code to handle the subtle changes in behaviour for vertex-declarations so we don't explode under the Metal validation layer. MVF works on macOS, though testing did expose an error with Tessellation on Nvidia (true for MVF enabled & disabled).

Change 3718633 by Guillaume.Abadie

	Fixes temporal instability issue of TAA upsample with secondary screen percentage.

Change 3718658 by Arne.Schober

	DR - 25% MorphTarget Speed increase because there was a bit of cache thrashing between the waves going on.

Change 3719375 by Mark.Satterthwaite

	Extend mtlpp compiler testing app to support Metal tessellation compute shaders so we can send Nvidia a much simpler reproduction of their regression.

Change 3720099 by Mark.Satterthwaite

	Make the left-hand arguments work in airdiff.

Change 3720413 by Mark.Satterthwaite

	Support standalone compute shaders in the mtlpp compiler test app.

Change 3721232 by Mark.Satterthwaite

	No more Metal Shader Model 4 - instead we have to have a Metal Shader Model 5 w/o Tessellation as Nvidia's shader compiler is broken on all tessellation shaders in 10.13.0 and above. There is no guarantee that they will fix this prior to 10.14 and I can't afford to disable tessellation entirely as if I do that then the AMD & Intel compilers will also regress. As there is no Shader Model 4 platform on Mac anymore I've amended the LevelEditorActions to disable the preview modes when no appropriate shader platform is available.

Change 3721244 by Mark.Satterthwaite

Change 3722766 by Rolando.Caloca

	DR - Fix static analysis

Change 3722943 by Mark.Satterthwaite

	Disable the METAL_SM5_NOTESS shader platform again - I can workaround the Nvidia pipeline state compiler crash by changing the buffer address space from "constant" to "device" as we're managing to confuse the poor thing. This won't materially affect AMD or Intel as they don't care much about this, but to limit performance issues on Nvidia we only need to do this for Tessellation Compute shaders.

Change 3723100 by Mark.Satterthwaite

	Apparently users like enabling Metal shader standards that won't work on their current OS, so don't display those that aren't going to work & display an error message before quitting rather than crashing when trying to load a project that tries to use an incompatible shader version.

Change 3723121 by Mark.Satterthwaite

	Fix build error.

Change 3723245 by Daniel.Wright

	Ensure for when a reflection capture upload fails due to incorrect lighting scenario level handling
	Reflection captures with no data use an array index of 0, instead of -1.  Might avoid reading uninitialized memory on PS4.

	[Dupliate] CL 3725548 - Fixed invalid screenpercentage value in VehicleGame sample (was setting -1 but should default to 100). This has always been broken but was recently exposed by CL 3686200.

Change 3726845 by Guillaume.Abadie

	Exposes SvPosition to material through screen position material expression, so that material no longer have SvPosition * InvViewSize * ViewSize precision loss.

	#jira UE-51428

	- Material no longer have to deal with BufferUV, and post process material after TAA upsample can sample any scene buffer seamlessly;
	- Material texture per view mip bias to produce sharper images with TAA upsample;
	- Render thread dynamic resolution heuristic is fully plugable by game code (for VR plugin specific heuristics);
	- Dynamic resolution in PIE and game builds;
	- Busy time queries in the RHI to be implemented on the different platforms so that the dynamic resolution heuristic can  exactly associate GPU frame times with screen percentages in its history;
	- Game user settings to enable/disable dynamic resolution;
	- In editor viewport screen percentage config to previsualise and test content at different screen percentage.

	Fixes:
	- Various fixes for algorithms producing different outputs at different screen percentage.
	- Various fixes for algorithms sampling outside view rects.

	Refactors:
	- TAA shader
	- Moved some screen percentage specific members from FSceneView to FViewInfo for thread race bullet proofing.

Change 3636225 by Daniel.Wright

	Removed spammy draw event

Change 3636397 by Daniel.Wright

	Visualize volumetric lightmaps uses 18% grey in lit mode

Change 3636398 by Daniel.Wright

	Translucency lighting modes work with Volumetric Lightmaps
	* The old Indirect Lighting Cache always interpolated one sample per object, while Volumetric lightmaps operate at the frequency of the Translucency Lighting Mode (per-vertex or per-pixel) so the lighting accuracy is much higher.
	* The old ILC always applied the single lighting sample with a per-pixel normal, even in per-vertex lighting modes
	* Volumetric PerVertex NonDirectional (cheapest lit translucency) went from 74 instructions down to 42
	* Volumetric Directional went from 104 up to 122

Change 3636604 by Chris.Bunner

	Added a material translation error on identically named/associated but differently valued parameters as this will cause one of them to be lost during parameter evaluation, the result being "random".

Change 3637668 by Rolando.Caloca

	DR - hlslcc - Skip preprocessor when not required which reduces peak mem consumption by ~500 MB
	- Fix missing indexing on intrinsic return type

Change 3638541 by Chris.Bunner

	Fixed editor materials - Skip hardcoded parameter names that we rely on being overridden when checking for non-matching duplicate parameters.

Change 3638798 by Mark.Satterthwaite

	Rebuilt hlslcc for Mac for Rolando's 3637668 changes.

Change 3638861 by Mark.Satterthwaite

Change 3639909 by Michael.Lentine

	Add special case for struct needed to compile.
	Workaround issues in parser such that (x)[0] is replaced with x[0] and (x).a is replaced with x.a.

Change 3639916 by Michael.Lentine

	Spelling fix.

Change 3640053 by Mark.Satterthwaite

	Fix Desktop Forward rendering on Nvidia Metal rendering on macOS by modifying the shader and runtime to treat ForwardLocalLightBuffer data as uint rather than float and invert the use of as*() casts.

	Tthis is *necessary* to avoid a bug/limitation of Nvidia's current Metal shader compiler that flushes all denorm values to zero on load from any resource. AMD & iOS Metal only flush-to-zero when sampling from textures and that's what Apple regard as the expected behaviour. I have however asked them to standardise on the D3D behaviour of preserving denorms on all load, move (incl. min/max/as*()-casts) & store operations. This won't happen in the current or imminent OS/Xcode releases.

	Now only Intel Metal is broken and their problems run deeper.

	#jira UE-48881

Change 3640983 by Olaf.Piesche

	Cache the depth buffer collision shader for GPU particles even when simple forward is enabled, as that can be turned off at runtime.

	#jira UE-48799

Change 3641480 by Michael.Lentine

	Add min16float to FP16Math

Change 3642442 by Mark.Satterthwaite

	Fix the native shader libraries again & undo the increase in cook time from changes to the way FShaderCodeLibrary was compiling & deduplicating the shaders.
	- Remvoe the single linear array for accumulated shader code: reallocating this is tremendously expensive and will double the time taken to iteratively cook large projects.
	- Uncompress the shader data for the native library system so that it actually works again.
	- Fix some errant change to the Metal compiler that was trying to wedge the fully compiled library into the single Metal library which is 100% bogus.

	#jira UE-49192

Change 3642919 by Chris.Bunner

	Reverted unintended changes to material static parameter set serialization.
	Bumped material version to force re-serialization.
	Fixed a few typos.

Change 3642923 by Richard.Wallis

	Fix for "Pixel Inspector On" message not disappearing when closing pixel inspector window while on.  Handle tab closed events to cancel the pixel inspector if window closed while running.

	#jira UE-46504

Change 3643296 by Michael.Lentine

	Convert all structures that aren't use globally to halfs.

Change 3643381 by Ryan.Brucks

	New Plugin allowing Blueprint Texture and RT reads as well as MIC creation and modification.

Change 3643929 by Ben.Salem

	Added better precision on thread values in Perf Monitor. Also added global thread values to go with per-world ones to help track down the most accurate numbers possible.

	#tests Ran locally, changes validated by benj

Change 3644203 by Mark.Satterthwaite

	Refactor mtlpp a little bit to make the compiler do more of the work & update for all the latest publicly exposed APIs.

Change 3644336 by Mark.Satterthwaite

	Ref-count the mtlpp Device object so that it can be the repository for IMP caching - now just have to go through the types created from a specific device and have them keep a reference....

Change 3644431 by Uriel.Doyon

	Added a intensity units property, for point lights and spot lights, that can be set to Candelas, Lumens or Unitless (legacy).
	The default units value for newly placed point lights and spot lights is configured in the project settings.
	Spot lights configured in lumens have their whole luminous energy redirected toward the cone.
	This means that changing the outer cone angle, changes the spot light brightness.
	New exposure menu that uses an EV100 slider.
	New post process settings "camera" tab regrouping : ShutterSpeed, ISO,  Aperture and ExposureCompensation.
	Post process settings "auto exposure" tab renamed "exposure".
	The calibration constant for "Auto Exposure Basic" is now configurable in the advanced tab.
	The auto exposure method is renamed "Metering Mode"

	New pre-exposure feature that allows the engine to apply the previous frame exposure before writing to the scene color.
	This allows the engine to render the scene with similar range than the final color (after exposure), and avoid arithmetic overflow for low precision RT formats.
	The amount of exposure applied directly is called pre-exposure, and is compensated by a smaller post-exposure value.

Change 3645098 by Marcus.Wassmer

	Don't add meshes twice when in simpleforward

Change 3645551 by Daniel.Wright

	VolumetricScatteringIntensity is greyed out based on Mobility

	DR - vk - Fix bad update texture 2/3d parameters

Change 3646463 by Mark.Satterthwaite

	Metal shader files that can serve as extensions to the metal_stdlib rather than trying to wedge even more into the shader compiler. Might as well leverage Metal's C++'ness.
	Currently just a skeleton of a buffer type that would better emulate HLSL Buffer<>/RWBuffer<> objects.

Change 3646727 by Marcus.Wassmer

	DR - Performance optimization during HLod traversal. using vector load and avoiding array copy by passing it through reference instead through value.

Change 3649443 by Daniel.Wright

	Exposed EmissiveBoost, since Lightmass supports Emissive areas on meshes

Change 3650436 by Mark.Satterthwaite

	Implemented the necessary extensions for Metal shading language to move lots of complexity out of MetalBackend and into actual shader code to make life *vastly* simpler.

	- Full ue4::typed_buffer<T> wrapper type & associated ue4::buffer<>/ue4::buffer_atomic<> API - totally untested but should be functionally equivalent to HLSL Buffer<T>/RWBuffer<T>.
	- All the sensible casts I can think of are now defined in ue4_format - any additional ones can just be added. The enurm of formats needs to be exposed to MetalRHI so we upload the correct values, but this should be trivial.
	- Added a full series of wrappers around texturecube_array and depthcube_array to insulate code from whether it is backed by a real cube_array or a texture2d_array so we don't have to maintain complicated variants for new/old iOS devices.
	- Added implementations for a bunch of annoying HLSL & GLSL intrinsics that were being matched by name + reverse_bits which needs a custom implementation on old shader standards.

Change 3650861 by Rolando.Caloca

	More work on mtlpp:
	- Selector class that caches IMP from SEL & Class.
	- Fixes to ns::Error.
	- Added test case application for testing denorm & float reinterpret-cast behaviour on Metal.

Change 3652370 by Uriel.Doyon

	New "stat StreamingOverview" giving high level metrics of texture usage.
	New function ResetAverageRequiredTexturePoolSize() and GetAverageRequiredTexturePoolSize() giving the average ideal value for "r.streaming.poolsize".

	Material vertex interpolator for sprite and gpu sprite particles.

Change 3653676 by Rolando.Caloca

	DR - vk - Integrate changes: Multiple PSO caches, shared ucode & compression, size reduction up to 80%

Change 3653940 by Daniel.Wright

	Moved Volumetric Lightmap textures out of FScene and into FPrecomputedVolumetricLightmapData so their lifetime can match the MapBuildData.  This allows tossing the source BulkData in game after RHI texture creation even though switching lighting scenarios does Release/InitializeRenderingResources multiple times.

Change 3653956 by Daniel.Wright

	Fixed leak of BatchVisibilityId's

Change 3653991 by Daniel.Wright

	Fixed missing include

Change 3654013 by Daniel.Wright

	Temporarily disabed a material error whilst working with content teams to fix the introduced bugs.

Change 3654534 by Daniel.Wright

Change 3654940 by Rolando.Caloca

	DR - vk - Warning fix

Change 3655104 by Mark.Satterthwaite

	Add a bunch of code to mtlpp to wrap the Xcode command-line Metal tools and use them to provide a convenient command-line tool that can compile two Metal shaders & diff the resulting AIR to make debugging easier. Obviously this only works on macOS.

Change 3655173 by Jian.Ru

	Render dithered material as masked if a stencil prepass is not used

	#jira UE-50064, UE-49537

Change 3655479 by Daniel.Wright

	Fixed HandleLegacyMapBuildData not getting called on P maps loaded in the editor, which apparently was dropped in an integration error, causing all legacy maps (before the BuildData change) to lose their built lighting.

Change 3656341 by Richard.Wallis

	Metal validation checks to test for drawing of the end of a vertex stream as seen in UE-48172 (Landscape Mesh Flickers Rapidly When Using Sculpting Landscape).  This is not a fix for that but just a error log to catch the bad draw calls.

	#jira UE-30086

Change 3659499 by Daniel.Wright

	Moved bEnableAutoLODGeneration to LOD category so it's not the only one in HLOD category

Change 3659644 by Mark.Satterthwaite

	D3D11 equivalent to 3656341 (only enabled when -d3ddebug is) to validate DrawIndexedPrimitives isn't trying to draw off the end of the instanced vertex streams which has inconsistent (and potentially undefined) behaviour across the various APIs we support. This fires when painting the landscape because the code attempts to render with a FirstInstance value that is as large as the number of elements in the instance-data streams which D3D11 drivers silently fails to render, but which Metal (& probably Vulkan too) will renders as garbage. This pattern is wrong & will be even more dangerous in a Draw*Indirect world.

Change 3662100 by Mark.Satterthwaite

	Use a temporary file and an atomic move to put the Metal PCH into the right place and reduce the number of false PCH compile failures on the build farm.

Change 3662253 by Daniel.Wright

	Reflection Captures support Lighting Scenarios without recapturing
	 * Reflection Captures are now part of the Map Build
	 * Modifying a capture in editor will display a preview, but game can only display built captures (black for unbuilt with screen message)
	 * Reflection Capture build data moved to the BuildData package
	 * Building lighting / reflection captures no longer dirties ULevels
	* Sky lights which capture the scene now work correctly with Lighting Scenarios
	* Lighting Scenarios must now be loaded for each time they are made visible (no switching back and forth while keeping both loaded)

Change 3663215 by Mark.Satterthwaite

	Initial, incomplete, tool added to mtlpp to help debug macOS Internal Compiler Errors - the mtlpp command-line tool can be fed the debug output from UE4 along with compiler settings to automatically compile shaders and construct the render pipeline that crashes the runtime compiler.
	So far only macOS render-pipeline-states are supported currently.

Change 3663293 by Mark.Satterthwaite

	Added Metal device selection to the mtlpp command-line tool so I can quickly test compile on dual-GPU Macbook Pro's.

Change 3663471 by Daniel.Wright

	Reflection Capture Builds no longer use UEditorLevelUtils::SetLevelVisibility to control level visibility, which streams out sublevels, modifying nav mesh
	Fixed status updates during Reflection Capture Build
	Captures overflowing GMaxNumReflectionCaptures now log a warning instead of pretending that they built successfully

	DR - Use hlslcc define for common issues

Change 3668108 by Brian.Karis

	Disabled to Catmull-Rom filter. Too many flickering issues. Disabled antiflicker as well.

Change 3668157 by Mark.Satterthwaite

	In the prototype Metal stdlib extension library add inline versions of the D3D SM6 "wave" intrinsics that can be expressed in terms of Metal 2.0 simd/quad group operations (macOS=simd, iOS=quad). These are unlikely to be as efficient as direct intrinsics but they should be functionally equivalent.

	These functions are not available *yet* as I still need to hook the ue4_stdlib into MetalShaderFormat & MetalRHI.

	The following HLSL 6 functions are implemented:
	WaveAllBitAnd
	WaveAllMax
	WaveAllMin
	WaveAllBitOr
	WaveAllBitXor
	WaveAllEqual
	WaveAllProduct
	WaveAllSum
	WaveAllTrue
	WaveAnyTrue
	WaveBallot
	WaveGetLaneCount
	WaveGetLaneIndex
	WaveOnce
	WavePrefixProduct
	WavePrefixSum
	WaveReadFirstLane
	WaveReadLaneAt

	The following can't be implemented in Metal as of Metal 2.0 AFAIK:
	WaveGetOrderedIndex
	WaveIsHelperLane
	GlobalOrderedCountIncrement
	QuadReadLaneAt
	QuadSwapX
	QuadSwapY

Change 3668260 by Olaf.Piesche

	Cache particle collision shaders regardless of simple forward state

	Bumped shader version to propagate FReflectionCaptureData rename

Change 3669369 by Mark.Satterthwaite

	Duplicating Metal changes from //UE4/Release-4.18 to Dev-Rendering (//UE4/Dev-Rendering)

	3662503 Collapse system-variables to one declaration in MetalUtils to avoid later shader compiler errors when they are specified more than once, which is seemingly permissable. Fixes volumetric fog.

	#jira UE-50293

	3665210 - Invalidate all Metal shaders again to force a recompile to workaround another driver bug.
	- On macOS compact the clip-distance value into a single output to avoid bugs in the runtime pipeline compilers.
	- In SCW's direct-compile mode MetalShaderForamt should always dump the resulting Metal shader and print any errors we encounter to the log.
	- Change FGenerateMetalVisitor to take a FMetalCodeBackend& not a FMetalCodeBackend* to avoid a lot of pointless pointer validation.

	#jira UE-50244

	3665429 Fix a crash on shutdown due to MetalRHI caching vertex-declarations beyond the lifetime of the RHI by moving the cache into the FMetalDynamicRHI itself.
	#jira UE-50356

	3665613 Fix DistanceField rendering on Metal & the associated validation layer error when it is enabled - MetalRHI can't use the same approach as Vulkan without a bit more work.

	#jira UE-50364

	3667584 Fix black flickering on some materials that use World Position Offset - the Metal sincos intrinsic comes into two flavours for single precision floats and we want the precise version not the fast version. The "cross" implementation needed a few more fma's too and this change has to invalidate Metal shaders again to take effect.
	#jira UE-50399

	3667805 Changing sincos in Metal fragment shaders had undesirable side-effects - the compiler is now re-associating another floating point operation - so limit the use of precise::sincos to vertex-shaders for now. This fixes the WPO materials without causing any other obvious problems.
	#jira UE-50399

Change 3669912 by Mark.Satterthwaite

	Fix Metal compilation for PCSS shadows - the HLSL that is compiled uses both SampleCmp and Sample which GLSL disallows (shadowSampler types in GLSL only allow SampleCmp) but is perfectly valid in Metal where only the texture type declaration changes.

	Duplicate MetalBackend.cpp changes from Joe.Graf's: 3667781
	Fixed an extra ) being emitted during HLSL->Metal translation
	Added depthcube_array support per Mark's instructions

Change 3670308 by Mark.Satterthwaite

	Missing autorelease pool blocks in MetalTexture functions.

Change 3670989 by Mark.Satterthwaite

	Stop trying to be so clever with Metal clip-distances: AMD have a bug in 10.13.0 that means we can only emit one clip-distance value, so simply emit the value with the lowest index (we have handily ordered them by importance!) and let the others become user-interpolators until this bug is resolved in a macOS SU (according to Max@AMD the fix is in, just not in time for 4.18). This means planar reflections will work, VR no-multi-view-fallback will work & layered rendering will work either individually or together - the difference being that on macOS *only* the VR no-multi-view-fallback & layered rendering paths may be slower when combined with the global clip plane.

	Hit & run fix to MetalCaptureManager and availability of tile-shader functions while I'm here.

Change 3672309 by Mark.Satterthwaite

	Submitted on behalf of Richard Wallis:

	Only disable V-Sync on Metal in macOS 10.13 when running in "true" fullscreen mode (where we switch display modes & forbid switching spaces or tabbing out) so that you won't see the rainbow artefact caused by being out-of-sync with WindowServer, only the tearing you'd expect when V-Sync is disabled. We'll chat with Apple about whether there is a way to avoid the rainbow artefact when switching spaces in Windowed Fullscreen with displaySync disabled.

	Fixed support for editor-time transient parameter overrides. This happens when a compiled material's scalar or vector parameter is changed in value only, the active material resources should also update and be reverted when the material graph is closed. The code was incorrectly pulling base parameters from expressions instead of the actual uniform.

	#jira UE-48254

Change 3608455 by Mark.Satterthwaite

	Enabling WorldPositionOffset requires disabling fast-math on Metal because the manually specified FMA's are not respected if one or more arguments is a literal which then leads to very different compiler optimisation between the depth-only shader and the base-pass shader. This change will only affect the way Metal compiles shaders.

	#jira UE-47372

Change 3608462 by Rolando.Caloca

Change 3608991 by Mark.Satterthwaite

	Fix a dumb bug when parsing the Metal compiler version that breaks Metal shader PCH generation on HFS+ volumes.

Change 3609090 by Uriel.Doyon

	StaticMeshComponent and LandscapeComponent now register AO material mask and sky occlusion texture in the texture streamer.
	Changing the current lighting scenario now triggers an update of the texture streamer, and a refresh of lighting data for instanced static meshes.
	Added an option to the "liststreamingtextures" named UNKOWNREF allowing to inspect texture without references in the texture streamer.
	BUILDMATERIALTEXTURESTREAMINGDATA now rebuild every shader in memory and mark for save those with different data.
	MipBias now behaves the same way in shipping than in other builds.
	Fixed texture resolution logic for editor tooltips and in game stats.

	#jira UE-48642

Change 3610552 by Mark.Satterthwaite

	Optimise the constant-propagation pass in hlslcc by using a hash-table to reduce the cost of looking up the existing constant assignment instructions. The get_assignment_entry drops from 25% of runtime to 2.2% of runtime on a 4.2Ghz Quad i7 2017 iMac.

	DR - hlsl - Actual fix for 0.r

Change 3611312 by Rolando.Caloca

	DR - Integrate: Improve performance of bokeh depth of field.
	* Fewer instances with more work (higher quad count) per instance.
	* Improves performance on RX 480 in the Infiltrator demo by 0.37 ms at 1080p and 0.50 ms at 1440p (average frame time over the beginning of the demo, including the hallway confrontation between the guard and the infiltrator, where heavy DOF is used).
	* Similar optimizations may be possible for other systems that perform similar "instanced draws of quads" (e.g. virtual texture page table updates, lens blur, and velocity scatter).

Change 3611345 by Mark.Satterthwaite

	Missed the hash-table destructor in previous change.

Change 3611372 by Rolando.Caloca

	DR - vk - New barrier/layout api

Change 3611445 by Mark.Satterthwaite

	Fix stupid bugs in MetalBackend's LoadRWBuffer helper function where the wrong type was being used - won't fix problems in the LinearTexture case though.

Change 3611686 by Mark.Satterthwaite

	Remove the sampler from the Metal Linear Texture SRV path as for reasons so far unknown it doesn?╟╓t work with the light grid culling.

	#jira UE-48881

Change 3611743 by Mark.Satterthwaite

	Implement early depth test for Metal - it is implemented such that manual specification of the SV_Depth* outputs will elide the early_fragment_test qualifier as Metal does not permit both at present.

Change 3611746 by Mark.Satterthwaite

	Use early fragment tests implicitly unless we perform a direct resource write or use discard - explicit depth writes always disable early fragment tests as Metal doesn?╟╓t allow both. This should better match D3D driver behaviour.

Change 3611756 by Mark.Satterthwaite

	Missed a header file in last commit.

Change 3611836 by Mark.Satterthwaite

	Fixed the use of Metal?╟╓s capture manager so that it doesn?╟╓t capture more frames than intended.

	Enabling Eye-Adaptation in TM-ShaderModels.

Change 3613205 by Mark.Satterthwaite

	Fully disable linear textures in Metal - they simply aren't performant. Instead we'll have to use helper functions to dynamically type-cast appropriately within the shader. This is currently only configured for a handful of UAV types and will need to be extended.

Change 3613208 by Mark.Satterthwaite

	Add code to MetalBackend to promote half types to float for math operations to avoid compiler errors.

Change 3613354 by zachary.wilson

	Volumetric lightmap visualization sphere size is now a fraction of the corresponding brick world size

Change 3613651 by Daniel.Wright

	Also added shrinking for GDistanceFieldUploadData which saved 15Mb.

Change 3613696 by Mark.Satterthwaite

Change 3618326 by Rolando.Caloca

	DR - vk - Fix transition flags

Change 3618408 by Daniel.Wright

	Lightmass skylight solver improvements
	* Lightmass uses a filtered cubemap to represent the skylight instead of a 3rd order Spherical Harmonic.  Directionality in shadowed areas is improved.  Mip level is chosen based on the ray differential for anti-aliasing.
	* Multiple skylight and emissive bounces are now supported with a radiosity solver, controlled by NumSkyLightingBounces in Lightmass WorldSettings.  More bounces results in longer build times, and the radiosity time is not distributable.
	* The mapping surface cache is now rasterized with supersampling, reduces incorrect darkness in corners
	* Combined direct lighting, photon irradiance, skylight radiosity and diffuse in the mapping surface cache so final gather rays only have to do one memory fetch, speeds up lighting builds by 7%.
	* Added support for Embree packet tracing although no solver algorithms use it yet

Change 3618413 by Daniel.Wright

	Swarm hands out the most expensive tasks in roughly a round robin ordering among distribution agents.  Lightmass processing of a single task is multithreaded, so ideally the most expensive tasks are evenly distributed among active agents.  This has the biggest impact in small scenes with 10's of high resolution lightmaps, and with a distribution farm.  Build time in one scene went from to 113s -> 47s.

Change 3618439 by Mark.Satterthwaite

Change 3621261 by Mark.Satterthwaite

	Trivial FMetalStateCache optimisations - won't help much but equally they shouldn't hurt.

Change 3621262 by Mark.Satterthwaite

	Correct the handling of MSAA target in Desktop Forward for iOS - now the problem is that iOS always creates an internal resolve target so which texture to bind depends on the shader parameter type. Not sure (yet) how best to solve that.

	#jira UE-48193

Change 3622986 by Mark.Satterthwaite

	A couple more trivial optimisations to MetalRHI for iOS:
	- Metal page size is 4k but only buffers under 512 bytes should go through set*Bytes on iOS to balance CPU cost.
	- On iOS the minimum buffer size should therefore be 1k and on Mac 4k as nothing else makes much sense.
	- No need to rebind uniform buffers if to the same slot - it just wastes cycles.

	One more workaround for a bug in StandardPlatformString.cpp. It doesn't handle %lf format correctly, parsing it as long double instead of ignoring the 'l' format sub-specifier.

Change 3628685 by Daniel.Wright

	CPU interpolation of Volumetric Lightmaps for the mobile renderer.  They use a scene cache based on interpolation position, since the precomputed lighting buffer for movable objects is recreated every frame.

Change 3632041 by Mark.Satterthwaite

	Fix cloth rendering on Metal - some of the data in FClothVertex is uint but we load it from a float buffer. This could be due to a bug in Metal's as_type<uint4>() or it could be that Xcode 9's compiler is now finally enforcing Metal's official flush-to-zero-on-load semantics for denorms - it isn't immediately obvious.

	#jira UE-49439

Change 3632261 by Brian.Karis

	SM4 fallback for reflection captures.

Change 3632281 by Mark.Satterthwaite

	Fix an intermittent assert on startup when the AVFoundation movie player gets the QAGame TM-ShaderModels video ready to play prior to the rendering thread being back online when resizing the window. This is done by deferring the processing of AVFoundation events to the game-thread where it won't cause a threading violation.

Change 3634319 by Mark.Satterthwaite

	Stop FVolumetricLightmapDataLayer ::Discard which is invoked by the Editor RHI during texture-upload from chucking the backing data when in the Editor - because if we do that then cooking will serialise an empty array. This was only apparent on Mac because Metal always invokes Discard on BulkDataInterfaces and D3D11 never does.

	Change 3544101 on 2017/07/19 by Thomas.Sarkanen@Dev-UEAP-29-PhATUpgrade-Thomas.Sarkanen

		Fixed up physics asset editor's use of debug skel mesh component

		This broke post-merge from Dev-AnimPhys.
		Kinda hacky, but we need to double-flip the buffers in this case as we want to force non-threaded work AND also wait on the physics tick group to complete (to blend in physics).
		This also requires making ShouldBlendPhysicsBones protected, otherwise the buffers are never flipped in the non=simulating case (before simulation is enabled in the physics asset editor).

	Source bus feature.

	- New architectural feature for audio mixer that allows audio sources to route to other audio sources.
	- Buses can be routed to each other
	- Buses have a duration which can be set in bus asset
	- Buses can choose between mono and stereo channels
	- Sources can send to buses and also toggle to *only* output to buses (and bypass submixing)
	- Will allow persistent source effects on different source audio, while also maintaining 3d spatialization capabilities. Lots of future features will build on this change: 3d audio-volume-based submixing, sidechaining, environment reflections, diagetic microphones, etc.

	- Some engine changes and optimizations:
	  - Format conversion to float is done in async workers for decode vs the render callback
	  - Procedural sound waves can opt to output only float vs int16 PCM data (avoids a format conversion in audio mixer)
	- Apply master attenuation at the final output vs per-source
	- Fixed code that performs fade in/fade out for smooth startup and shutdown.
	- Moved FSourceParam to FParam into DSP utility so others can use it.
	 - Some engine fixes:
	    - Audio spat plugins that are external sends will not send audio to default/base submix. But will also allow their audio to be panned and sent to submix sends (e.g. reverb) so external HRTF rendering can also get reverb effects, etc.
	  - Fixed an issue with pause
	  - Fixed an issue with the final source buffer in a source voice not getting properly rendered and causing discontinuties
	- Fixed an issue with WorldID not getting set for listeners
