4bf590b04d Fix nans on vulkan.
hlslcc was incorrectly converting conditionals to mix. When one of the operand is a nan, this conversion is incorrect, as the nan will propagate, and thus we get weird bugs where the nans stick around.

  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

Change 3872507 by Arne.Schober

Change 3988916 by Marcin.Undak

	Quail/Linux compilation fix #rb none #codereview arciel.rekman

Change 4042277 by Rolando.Caloca

	DR - Clear UBs between PSOs on D3D to help track down not setting resources

Change 4042297 by Arne.Schober

	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

	#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.

	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.

Change 4048308 by Uriel.Doyon

	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.

	UEVR-1100 bLockToHmd false doesn't work correctly
	-CameraComponent can now tell the LateUpdateManager to store, correctly buffered, the fact that we don't want to do late update this frame.  DefaultXRCamera checks that flag before applying the late upate to the camera.
	#jira UEVR-1100
	#review-3956168

Change 3957945 by Jeff.Fisher

	Fix for Oculus begin/end frame problem after XRRenderBridge refactor.
	-The 'Frame' lifetime in the frame was not long enough, so it was null by the time GetActiveRenderBridge_GameThread was called.  NextFrameToRender is the same value, but has a long enough lifetime.
	#review-3957897

	//UE4/Dev-VR-Seal/Engine/Source/...
	to //UE4/Dev-VR/Engine/Source/...

	UEVR-1148 bLockToHmd change breaking qagame entry level xr camera behavior
	-Fixing late update when no camera component is in use.
	-The camera component's bLockToHMD==false behavior is supposed to be that hmd motion is ignored, meaning we should not do a late update.  This behavior is being applied TO the XRCamera system FROM the camera component, but the camera component can go away or be switched at any time.  We want the default to be do apply hmd motion and late update, so disabling late update needs to be a positive setting applied each frame.

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

Change 3774677 by Arne.Schober

	DR - Deprecated SetLocal from the RHICmdlist
	Fixed some unnecessary PSO collisions.

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.

	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.

	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.

	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).

Change 3932819 by Daniel.Wright

	[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
	Base pass sets View Uniform Buffer from DrawRenderState instead of choosing which one to set per-draw

	Fixed padding in nested uniform buffer structs
	Skip SRV members on Feature Level SM4 and below

Change 3932964 by Rolando.Caloca

	DR - vk - Renderdoc on Android

Change 3933095 by Daniel.Wright

	Moved FSceneTextureUniformParameters out of the opaque base pass uniform buffer.
	* Base Pass shaders now enable SCENE_TEXTURES_DISABLED when compiling for a material of any domain other than MD_Surface.  These are used when rendering thumbnails of a material in a different domain, which could be opaque, but the opaque base pass drawing policy does not bind a scene textures uniform buffer, so the shader must not bind it.
	* Opaque materials can no longer use EyeAdaptation.

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.

	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.

	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.

Change 3993923 by Krzysztof.Narkowicz

	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.
	3. This resulted in a StaticMeshComponent with stale RenderData pointer.

	Texture Streaming Changes and Fixes:
	- Using the small FOV items (like scopes) now only affect visible primitives (through "r.Streaming.MaxHiddenPrimitiveViewBoost").
	- Static components added after the level is registered in the streaming manager are now handled correctly (fixes the low quality on the chests)
	- Dynamic components do not need to register to the streaming manager anymore.
	- Optimized dynamic component management by removing duplicate entries in the update list.
	- Added a pregarbage collect pass to the dynamic component management to optimize GC handling.
	- Added a budget reset logic whenever the scene requirements change significantly.
	- PIE worlds now have correct visibility information.
	- Fixed possible invalid memory access when processing the streaming manager slave views.
	- Refactored the incremental level texture data build to prevent new components from being unhandled.
	- Removed StreamingManager callbacks for NotifyActorSpawned() and NotifyPrimitiveAttached()
	- Added a StreamingManager callback NotifyPrimitiveUpdated(), to be used whenever a primitive streaming state must be updated.

	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.

	Fix broken rendering on Metal that tracked back to the innocuous looking changes in CL #4006495 (no blame attached - these changes are entirely reasonable) and cause various bugs in QAGame's TM-DistanceFields, ElementalDemo and probably more. Doesn't fix broken SpeedTree rendering :(.

	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.

Change 4025337 by Yuriy.ODonnell

	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.

	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.

Change 4034489 by Daniel.Wright

	Fixed UStaticMeshComponent modifying its UStaticMesh when undoing a change.  This caused a crash when other static mesh components using the same mesh asset were rendered, since their rendering state was not recreated.  A component should not modify its asset during PostEditUndo.
	 * This behavior has been present for a long time but was previously hidden because only the vertex factory of the mesh asset is cached in static draw lists, not any of its rendering resources (eg vertex declaration).

	Ray Traced Distance Field shadows use a two pass tile culling algorithm with no tile max - fixes flickering from tile overflow in dense areas or with a low sun angle.  Costs .2ms on PS4.
	The distance field scene buffers now use float4 on PS4 and Xbox, saves .1ms on PS4.

Change 3817029 by Uriel.Doyon

	Added UVolumeTexture, which use 3D textures. Compressed formats are supported on DX11, DX12, PS4 and XB1.
	Projects targetting OpengGL don't have access to compressed formats (as the implementation has texture tiling issues).
	Add "r.AllowVolumeTextureAssetCreation" set as 0 by default, which controls whether volume texture can be sampled in materials and whether they can be created from 2D texture assets.
	Platform not supporting BC7, will now fallback on RGBA8 instead of DXT to preserve quality, in an attemps to increase usage of BC7.

Change 3903799 by Daniel.Wright

	[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.
	* RemoveUniformBuffersFromSource() which works around HLSLCC lack of struct initializers now handles nested structs

Change 3917500 by Rolando.Caloca

Change 3979171 by Mark.Satterthwaite

	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.

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.

	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.

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.

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.

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.

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).

	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.

	[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.

Change 3892211 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).

	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.

	Make Manual Vertex Fetch a property of the shader platform for Metal - only the desktop platforms (METAL SM5/SM5_NoTess/MRT) will use manual vertex fetch. The mobile platforms use vertex descriptors. Prevents problems with cooked versions of games not working properly on Metal due to a mismatch between the runtime's Manual-Vertex-Fetch state versus the state used by the cooker when compiling shaders.

	* added Total and Untracked stats to LLMFULL. LLMFULL now tracks almost all of the memory that LLMPlatform does, so there is no real need to use LLMPlatform. Removed the LLMPlatform csv.
	* added FMalloc Unused stat to LLMFULL to account for memory Binned2 has allocated internally. This can be used to track Binned2 fragmentation over time.
	* renamed Binned stats to FMemory to make it more general
	* added Default tracking to CustomVirtualAlloc and disable it where necessary. This catches the few VirtualAlloc calls that were missed.
	* added AllocType arg to all allocation tracking. This was needed in order to track the FMalloc total, and also to fix the pausing

	Merging CL 3659069 from //Fortnite/Main/... to to //ue4/dev-console/...:

	[FORTNITE] [CONSOLE] [+] Improved frame syncing mechanism
	 - Improves input latency by allowing the game thread to sync to the swap chain flip of the previous frame.
	 - Added "r.GTSyncType" CVar to control how the game thread syncs with the rest of the pipe.
	 - r.GTSyncType 2 will sync the game thread with the flip of the swap chain, preventing the pipe from getting too long and causing excess input latency.

	Platforms are required to implement RHIWaitForFlip and RHISignalFlipEvent, and call RHIInitializeFlipTracking on RHI startup.
	A separate thread monitors the progress of frame flips and signals task graph events as they pass their corresponding frame index.
	In r.GTSyncType 2 mode, the game thread is signaled by this flip tracking thread.

	[~] Unified platform specific sync interval CVars into one: rhi.SyncInterval
	 - 1 == 60Hz
	 - 2 == 30Hz
	 - 3 == 20Hz

Change 3675239 by Keith.Judge

	Fixed thread priorities for Windows so that BelowNormal and SlightlyBelowNormal are the same. Bumped Lowest down a notch so they all fit.

Change 3726532 by Luke.Thatcher

	[CONSOLE] [~] Enable XGE shader compilation by default.
	 - Also set XGE mode to "force interception". With XGE on by default, we don't want people with an old Incredibuild version using the old system inadvertently.

Change 3726554 by Luke.Thatcher

	[CONSOLE] [+] Improved Scoped Named Events
	 - Added SCOPED_NAMED_EVENT(_FSTRING/_TEXT/_F) macros to allow use of string literals, FString and printf in scoped named event strings.
	 - Replaced explicit use of FPlatformMisc::Begin/EndNamedEvent throughout the engine with macros, so the events can be compiled out.
	 - Fixed performance issues on various platforms with named events. SCOPED_NAMED_EVENT macros were not considering whether the platform uses wide or ansi char strings.

Change 3788417 by Ben.Woodhouse

	Duplicate from FN CL 3712515
	CSV profiler GPU and pre-declared stat support
	- refactor the GPU profiler so it's no longer dependent on the stats system and can work in Test builds
	- add support for pre-declared CSV stats, using FNames (these are required for GPU stats)
	- add DECLARE_GPU_STAT macro which handles STATS and CsvProfiler declarations
	Note: still a few issues to resolve with GPU stats: these randomly go to 0 at times during a replay on XB1, the GPU total is lower than the stat unit number, and the unaccounted stat is too large due to missing stats

Change 3813513 by Ben.Woodhouse

	CSV profiler refactor+ bug fix
	- Move the CSV profiler to core, so we can use it in modules other than engine
	- Profiler no longer enqueues RT commands - this is handled by a new core delegate type
	- Make begin/end requests more robust, enqueued via a command queue and processed in order
	- Defer end capture requests by a frame. This ensures stats on threads other than the gamethread (e.g. renderthread etc) are complete, so the last frame is not truncated
	- Fix long-standing bug with multiple captures where old/stale frames would appear in the first <128 frames of captures
	- Move unit stats and dynamic resolution out of the profiler itself and into the engine. Only frametime is recorded in the profiler now
	- Fix longstanding bug in first frame renderthread time in the engine

Change 3814039 by Ben.Woodhouse

	More Csvprofiler improvements
	- Event support (via CSV_EVENT macros). These appear in the "EVENTS" column of the CSV and can be used to add context to the stat data
	- Reduced memory overhead for timestamps through bit-packing (now 16 bytes per marker instead of 24), and splitting stats into different types

Change 3814041 by Ben.Woodhouse

	Integrate as edit CL 3796390 from Fortnite/Main:

	Fix CsvProfiler not compiling in shipping for now

Change 3814229 by Ben.Woodhouse

	Integrate + refactor of CL 3792591 to reduce complexity and fix bugs

	Original changelist description:
	CSV profiler improvements:
	- The CSV profiler is now always compiled in on the server
	- The CSV profiler can now handle both int32 and float stats
	- In BeginCapture, the function can take additional arguments for some customization of filenames

	Fixes to the above:
	 - Remove FCustomValue class
		- Fixes bug where all timestamp values from CSV_SCOPED_STATs were garbage (due to issues resulting from FCustomValue type ambiguity when adding values together)
		- FCsvCustomStat now just uses simple union + bitfield flag to reduce size and complexity (4 bytes instead of 8 per value)
		- FCsvColumn class modified to use doubles, which can represent both ints and floats without loss of precision - this class is not memory or time critical
	 - Replace multiple overrides used by the server for filenameprefix/folder/postfix etc with a single FilenameOverride

Change 3814242 by Ben.Woodhouse

	Disable CSV unit stats on the dedicated server

Change 3817339 by Ben.Woodhouse

	Duplicate from 3816641: CSV profiler improvements
	- Added a low-pri processing thread to compress raw timing data into a much more efficient format
	   - Reduces memory usage for 15 minute 30k frame capture with GPU stats enabled from 110MB to 3.4MB
	   - Processing time : 0.1ms per frame
	- Improved name handling for char literal stats. We now use the string as the ID rather than the pointer so multiple stat uses of the same name string apply only to  a single stat
	- Reworked thread data access to eliminate locking for anything time-critical. Frame boundaries now handled via a lock-free helper class
	-  Fixed bug with queue implementation where 1 in 128 reads would duplicate the last block of stat data
	-  Reduced #include dependencies for CSVProfiler.h
	-  Removed AccumulateMax because it doesn't work, and implementing properly would add a lot of complexity
	-  Added a simple test harness

Change 3817582 by Ben.Woodhouse

	Fix android compile warning

Change 3823242 by Ben.Woodhouse

	Integrate as edit from Fortnite/Main 3820067:

	Fix threading issue with D3D12 pipeline state caches for windows. This was caused by the usage of FRwScopeLock::RaiseLockToWrite. A pointer read before RaiseLockToWrite was called was invalidated because RaiseLockToWrite has to release the read lock before acquiring the write lock.

	Rename FRwScopeLock::RaiseLockToWrite to ReleaseReadOnlyLockAndAcquireWriteLock_USE_WITH_CAUTION to make it more explicit what's happening. As the comment says:

		// This function should be used with caution.
		// It releases the read lock _before_ acquiring a new write lock. This is not an atomic operation and the caller should
		// not treat it as such.
		// E.g. Pointers read from protected data structures prior to this call may be invalid after the function is called.

Change 3823840 by Ben.Woodhouse

	Edigrate from 3823816
	Fix an issue where the csvprofile console commands would sometimes result in an empty CSV. The root cause was GFrameNumber incrementing between the console command being read and FCSVProfiler::EndFrame(). We now use our own frame counter which is updated in EndFrame, so this can't happen

	Also fix an issue where calling csvprofile stop twice would cause all further commands to be ignored.

Change 3861774 by Ben.Woodhouse

	Integrate as edit CL 3833918 from dev-rendering (courtesy of DanielW):
	D3D12 RHI: only refcount uniform buffers if GRHINeedsExtraDeletionLatency is false, which is no longer the case for PC. The refcounting was heavy on performance as reported by a licensee because FRHIResource uses atomics for refcounting, which is only necessary when GRHINeedsExtraDeletionLatency is disabled.

Change 3862214 by Ben.Woodhouse

	Integrate-as-edit CL 3859637 from Fortnite/Main
			Dynamic resolution console tweaks
			- Dynamic resolution high level switch driven by a cvar instead of code
			- Disable user settings dynamic resolution handling on non-desktop platforms. DynamicRes as a user setting does not make sense on consoles/mobile - we'll drive it from device profiles/scalability
			- Modify naming of GPUHeadRoom to make it clear that it's a percentage, not millseconds

Change 3863919 by Ben.Woodhouse

	[Copy] Integrate console dynamic resolution interface changes from CL 3863354, 3862754, 3862639

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

Change 3441680 by Uriel.Doyon

	Added units to point light intensity, to allow the user to specify the value in candelas or lumens.
	New point light actors now configure the intensity in candelas by default.
	Replaced viewport exposure settings by an EV100 slider.
	Hidding the tone mapper in the show flag now still applies the exposure.
	Added a new AutoExposure method called EV100 which allows to specify :
	- MinEV100, MaxEV100
	- Calibration Constnat
	- Exposure Compensation
	#jira UE-42783

Change 3454934 by Chris.Bunner

	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

	Missed making a log verbose in the Metal ring-buffer.

Change 3639482 by Rolando.Caloca

	DR - vk - Minor fixes

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

Change 3645707 by Chris.Bunner

	Skip empty parameters when identifying invalid duplicates during material translation.

	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

Change 3647918 by Chris.Bunner

	Static analysis fixes - Monolithic include, forward delcared enums, locally shadowed variable.

Change 3648010 by Michael.Lentine

	Don't use min16float by default.

Change 3648015 by Michael.Lentine

Change 3648326 by Rolando.Caloca

	DR - vk - Added subrectangle support when updating Texture2D and Texture3D

Change 3648522 by Rolando.Caloca

	DR - vk - Do not try to create a BufferView of a StructuredBuffer (no valid pixelformat)

Change 3648612 by Rolando.Caloca

	DR - vk - Implement RHIMapStagingSurface

Change 3648673 by Rolando.Caloca

	DR - vk - Reduce Vulkan pipeline cache disk size by filtering duplicated shader ucodes

Change 3648913 by Arne.Schober

	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

	DR - vk - Fix warnings

Change 3651116 by Rolando.Caloca

	DR - vk - Support for compressed saved PSO cache

Change 3651321 by Rolando.Caloca

	DR - vk - Prep for load multiple PSO files

Change 3651337 by Chris.Bunner

	Editor-only default material fallback (hardcoded material).

	#jira UE-48404

Change 3651839 by Rolando.Caloca

	DR - vk - Integrate minor pipeline changes

Change 3652042 by Mark.Satterthwaite

	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".

Change 3653658 by Chris.Bunner

	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

	Refactored reflection capture composite SM4 handling, now forces fully rough even if !REFLECTION_COMPOSITE_USE_BLENDED_REFLECTION_CAPTURES (forward shading default)

Change 3654018 by Daniel.Wright

	Remove unused SM4 reflection capture cubemap

Change 3654118 by Rolando.Caloca

	DR - vk - Fix for queries; support for r.Vulkan.ProfileCmdBuffers to only time cmd buffers w/o gpu bubbles

Change 3654339 by Chris.Bunner

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

Change 3654534 by Daniel.Wright

	Editor is only supported on Feature Level 5 platforms.  Added a message box and exit when SM4 is detected (d3d10, OpenGL 3).

Change 3654751 by Rolando.Caloca

	DR - vk - Add readback for RGB10A2; minor optimization

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-48172

Change 3656844 by Rolando.Caloca

	DR - vk - Avoid microcode copy

	#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 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

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 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.

	DR - Fix issue when recycling image handles

Change 3512338 by Michael.Lentine

	Fix precision if user enters a multiple of 90 degree rotation for transforms.

	This will only work for exact values. Generally comparing float point numbers using == is unsafe but it should be ok in this case as they are exact values entered from the UI. We may want to later expand this to include thresholding using a value ~1e-7.

Change 3513112 by Richard.Wallis

	Crash when packaging for iOS with Shared Material Native Libraries and Share Material Shader Code from windows platform.  Offline shader compile for archiving not done - shader header has missing offline compile flag for native Metal library archiving.

	Fix includes:
	- Handle offline compile failure when not running on Mac and no remote is configured (or remote fails). (I think it's this point at which the crash in the bug report is at).
	- Make sure remote can build for native Metal libraries and archive correctly - this should now support Linux platforms or Mac to Mac (if enabled in MetalShaderCompiler.cpp) for testing if required.
	- Updated to include remote calling into the xcode 9 Metal pch fix already submitted by Mark Satt.

Change 3517039 by Yujiang.Wang

	GitHub #2655: Optimization for shadow map resolution selection for spot lights

	* Use the radius of the inscribed sphere at the cone end as the spot light's screen radius

	Note: slight drop of shadow quality of spot lights may occur when they are far away from the camera. This is intended, since before this optimization they tend to be always rendered with the maximum shadow map resolution (2048), which is very costly

	#jira UE-33982

Change 3517069 by Yujiang.Wang

	Fix for ScissorRect settings in d3d11 being lost under certain scenarios

	* Scissor rectangle is always enabled in the low-level d3d11 pipeline, and it is expected that at least one ScissorRect is present no matter whether RHISetScissorRect is called with bEnable=false (when it is false we just use a big rect to make it effectively disabled)
	* However FD3D11StateCacheBase::ClearState() clears all the states, which removes scissor rectangles and causes problems for certain routines (FScene::UpdateSkyCaptureContents)
	* Now SetScissorRectIfRequiredWhenSettingViewport will always set a effectively disabled ScissorRect on each FD3D11DynamicRHI::RHISetViewport call, just like d3d12 does

	DR - Fix linking issue

Change 3525459 by Daniel.Wright

	Volumetric Lightmaps - higher quality precomputed GI on dynamic objects and GI on Volumetric Fog
	* Enabled by default on all maps, effective after a lighting build.  This replaces the existing Precomputed Light Volume and Indirect Lighting Cache features.
	* New Lightmass World Settings: VolumeLightingMethod, VolumetricLightmapDetailCellSize and VolumetricLightmapMaximumBrickMemoryMb.
	* Lightmass computes lighting samples in an adaptive grid, with higher density around geometry inside the importance volume.  Positions outside the importance volume get lit with the border texels.
	* Improved Lightmass volume solver to use importance photons and full adaptive final gather, so volume samples have similar quality to 2d lightmaps.
	* A static indirection texture is built covering the importance volume and flattening the brick tree by storing the offset to the highest density brick at each indirection cell.
	* Seamless and efficient GPU interpolation across density levels is achieved by adding a single row of padding to bricks, copied from neighbors, and stitching up bricks with lower density neighbors
	* The Volumetric lightmap stores Irradiance as a 3 band SH, which is 27 floats, quantized into 28 bytes, 7 texture lookups.
	* A full screen barebones material using Volumetric Lightmaps costs .42ms on 970 GTX, while Indirect Lighting Cache Point costs .32ms
	* Sky bent normal is also stored for stationary skylights and Directional Light Shadowing for Single Sample Shadow receiving.
	* Volumetric fog, Movable components, unbuilt Static Components, SingleSampleShadow receiving and Capsule Shadows use Volumetric Lightmaps if available
	* New Visualization show flag for Volumetric Lightmap sample points
	* Level streaming of volume light data is not currently supported with this method

Change 3525461 by Daniel.Wright

	Lowered default r.Shadow.RadiusThreshold for Epic shadow settings as it was causing a lot of visible artifacts from small objects popping out.  This will increase shadowmap cost slightly (13.5ms RT -> 14.3ms RT in Fortnite on PS4, no measurable GPU difference).

	* A new LightTangent is added to FDeferredLightData
	* Packed all the values from LightSceneProxy->GetParameters into a single FLightParameters struct to avoid copy-pasting them everywhere

Change 3541129 by Rolando.Caloca

	DR - vk - Copy all Vulkan fixes from 4.17

Change 3541347 by Yujiang.Wang

	Fix wrong ViewFlags being set between objects when rendering shadow depth maps

Change 3543239 by Arciel.Rekman

	hlslcc: remove FCustomStd* workarounds.

	- This was previous attempt to work around problems arising from different STL used for building libhlslcc (in the cross-toolchain) and possibly different STL used for building engine (on the system).

Change 3545241 by Daniel.Wright

	Fixed spotlight whole scene shadows using a radius 2x too long

Change 3545347 by Daniel.Wright

	Fixed shadow occlusion culling broken by shadowmap caching change.  FProjectedShadowKey is now computed correctly for whole scene shadows and SDCM_StaticPrimitivesOnly shadowmaps will fall back to the query for a SDCM_MovablePrimitivesOnly, since the static primitives shadowmap's query is not issued every frame.

Change 3546196 by Marcus.Wassmer

	Fix minor typo

Change 3546459 by Daniel.Wright

	ULevel::PostEditChangeProperty recreates rendering resources if MapBuildData is modified - fixes a crash when Force Deleting the MapBuildData package.

	[Copy] Fixed UWorld::DestroyActor in PIE calling InvalidateLightingCacheDetailed which can do a FlushRenderingCommands and cause a large hitch

Change 3546836 by Daniel.Wright

	[Copy] ULightComponent::InvalidateLightingCacheInner uses MarkRenderStateDirty instead of slow reregister + FlushRendingCommands, and only for lights which might have static lighting data

	* Soft source radius controls how 'blurry' the shape of specular lighting looks
	* Implemented by LobeRoughness modification
	* Better approximation for spherical lights so that they don't look sharp when the radius is large using 'smoothed representative point' method
	* Suppoted LightTangent in forward shading

Change 3548865 by Daniel.Wright

	With shadowmap caching of whole scene shadows, only one of the cache modes issues an occlusion query.  Fixes a crash where the static primitive shadowmap is culled but the movable primitive shadowmap is visible, which is normally not possible.

Change 3548952 by Rolando.Caloca

	DR - Allow separate samplers in the shaders on Vulkan

	Fix the GPU hang on iOS caused by changes to the Depth-Stencil MSAA handling: you can't store the MSAA stencil results on iOS < 10 unless you use the slower MTLStoreActionStoreAndMultisampleResolve which we don't need for the mobile renderer.
	#jira UE-48342

Change 3587866 by Mark.Satterthwaite

	Correctly fix iOS compilation errors against Xcode 9 Beta 5 and Xcode 8.3.3 - duplicating function definitions is guaranteed to be wrong.

Change 3588168 by Mark.Satterthwaite

Change 3590905 by Mark.Satterthwaite

	For Metal shader compilation where the bytecode compiler is unavailable force the debug compiler flag and disable the archiving flag because storing text requires this.

	#jira UE-48163

Change 3590961 by Mark.Satterthwaite

	Submitted on Richard Wallis's behalf as he's on holiday:

	Mac fixes for Compute Skin Cache rendering issues (resulting in incorrect positions and tangents) and for recomputing tangents.  Problem sampling from buffers/textures as floats with packed data.  Some of the data appears as denorms so get flushed to zero then reinterpreted as uints via asuint or in Metal as_type<uint>().  Fix here for Metal seems to be to use uint types for the skin cache SRV's and as_type<> to floats instead.

	There could be some other areas where we're unpacking via floats that could affect Metal and I'm not sure how this will impact on other platforms.

	#jira UE-46688, UE-39256, UE-47215

Change 3590965 by Mark.Satterthwaite

	Remove the Z-bias workaround from Metal MRT as it isn't required and actually causes more problems.

	Remove support for Mac OS X El Capitan (10.11) including the stencil view workaround.
	Bump the minimum Metal shader standard for Metal SM4, SM5 & Metal MRT to v1.2 (macOS 10.12 Sierra & iOS 10) so we can use FMAs and other newer shader language features globally.
	Enable the new GRHIRequiresRenderTargetForPixelShaderUAVs flag as Metal is like Vulkan and needs a target for fragment rendering.
	Also fix the filename for direct-compile & remove the old batch file generation in the Metal shader compiler.

Change 3592171 by Rolando.Caloca

Change 3594999 by Mark.Satterthwaite

	Disable MallocBinned2 for iOS as on Rhino it worked but on iOS 10.0.2 there are bugs (munmap uses 64kb granularity, not the 4096 the code expects given the reported page-size).
	While we are here remove the spurious FORCE_MALLOC_ANSI from the iOS platform header.

	#jira UE-48342

Change 3595004 by Mark.Satterthwaite

	#jira UE-48748

Change 3606009 by Mark.Satterthwaite

	Correctly implement ClipDistance for Metal as an array of floats as required by the spec. and fix a few irritating issues from the merge that should not have.
	- When compiling a tessellation vertex shader in the SCW direct mode we can't evaluate non-existant defines and we don't actually need to.
	- The define names, values & shader file name are irrelevant to the Metal output key, but the shader format name & Metal standard really do matter - should speed up Metal shader compilation a bit.
	- Move the shader vertex layer clip-distance to index 2 to avoid conflicts.
	- Don't default initialise the debug code string for Metal shaders or it won't print out the actual code....

	#jira UE-47663

Change 3606108 by Mark.Satterthwaite

	Temporary hack to avoid a crash in AVPlayer.

Change 3498112 by Ben.Marsh

	UBT: Respect the option to not create debug info in the Android toolchain. This option is already being respected by the compiler, but the linker adds debug info of its own.

Change 3500239 by Robert.Manuszewski

	Made sure the Super Class token stream is also locked when assembling Class token stream with async loading thread enabled. This to to prevent race conditions when loading BP classes.

Change 3500395 by Steve.Robb

	Extra codegen savings when not in hot reload.

Change 3501004 by Steve.Robb

	EObjectFlags now have constexpr operators.

Change 3502079 by Ben.Marsh

Change 3504712 by Ben.Marsh

	UAT: Less spammy log and error output from UAT.

	* Callstacks for AutomationExceptions are suppressed by default but still included in the log (the path to the log is noted in console output with the message from the exception).
	* Add a mechanism for any exceptions to be caught and rethrown with additional lines of context (CommandUtils.AddContext()) that will be appended to the error output by UAT. Avoids decaying the exception type or masking the inner exception message while still adding additional information.
	* AggregateExceptions resulting from exceptions on child threads are automatically unwrapped (full details are still appended to the log)
	* Name of the calling function is not included in console output by default, but still included in the log.

Change 3504808 by Ben.Marsh

	UAT: Suppress P4 output when running a recursive instance of UAT.

Change 3505044 by Steve.Robb

	Fix deterministic cooking issue; always use a pseudo-random number stream when compiling a module.

Change 3505699 by Ben.Marsh

	Plugins: Store the bEnabledByDefault flag exactly as it was read from disk rather than collapsing it to an absolute value based on the default for the location it was read from. This allows loading/saving plugin descriptors without any knowledge of whether they are game or engine plugins.

Change 3506055 by Ben.Marsh

	UAT: Add a class to apply a log indent for the lifetime of an object (ScopedLogIndent), and use it to apply an indent to MegaXGE/ParallelExecutor output.

Change 3507745 by Robert.Manuszewski

	Moved FSimpleObjectReferenceCollectorArchive and FSimpleObjectReferenceCollectorArchive to be internal archives used only by FReferenceCollector so that they are constructed only once per GC task instead of potentially multiple times per GC (as was the case with UDataTables and BlueprintGeneratedClasses).

Change 3507911 by Ben.Marsh

	Plugins: Minor changes to plugin descriptors.

	* Add a distinct setting for an unspecified EnabledByDefault setting in plugin descriptors.
	* Add a function to IPlugin to determine the effective EnabledByDefault setting, based on where the plugin was loaded from.

	PR #3707: Fixed UBT stack size (Contributed by gildor2)


Change 3511808 by Ben.Marsh

	Optimize checks for whether the game project contains source code. Now stops as soon as the first file is found and ignores directories beginning with a '.' character (eg. .git)

	#jira UE-46540

Change 3512017 by Ben.Marsh

	Plugins: Deprecate the QueryStatusForAllPlugins() function; the same functionality is available via the IPlugin interface.

Change 3513935 by Steve.Robb

	Reverted array iteration in FPropertyNode::PropagatePropertyChange as this is now covered in TProperty::InitializeValueInternal() as of CL# 3293477.

Change 3514142 by Steve.Robb

	MemoryProfiler2 added to generated solution.

Change 3516463 by Ben.Marsh

	Plugins: Create a manifest for each PAK file containing all the plugin descriptors in one place. Eliminates need to recurse through directories and read separate multiple files in serial at startup, and allows reading all plugin descriptors with one read. The "Mods" directory is excluded from the manifest, since these are intended to be installed separately by the user.

Change 3517860 by Ben.Marsh

	PR #3727: FString Dereference Fixes (Contributed by jovisgCL)


Change 3517967 by Ben.Marsh

	Force a GC after hot reload to clean up reinstanced objects which may still tick.

	#jira UE-40421

Change 3520480 by Robert.Manuszewski

	Improved assert message when the initial package read request was too small.

Change 3520590 by Graeme.Thornton

	SignedArchiveReader optimizations
	 - Loads more stats
	 - Stop chunk cache worker from waking up continuously to poll for work. Only wake up when triggered by the archive reader
	 - Signed archive reader just yields when waiting for buffers to finish loading, rather than sleeping for some arbitrary amount of time
	 - Track the number of pending read requests in an atomic counter, to save having to lock the request queue to check for new entries

Change 3521023 by Graeme.Thornton

	Remove spin from signed archive reader. Main thread waits on an event triggered by the chunk worker to indicate that new chunks are ready for processing

Change 3521787 by Ben.Marsh

	PR #3736: Small static code analysis fixes (Contributed by jovisgCL)


Change 3521789 by Ben.Marsh

	PR #3735: Fix case sensitivity issue in FWindowsPlatformProcess::IsApplicationRunning. (Contributed by samhocevar)


Change 3524721 by Ben.Marsh

	Move Linux SDL initialization into FLinuxPlatformApplicationMisc. Attempting to move functionality related to interactive applications (graphics, input, etc...) into a separate place, so it can ultimately be moved out of Core.

Change 3524741 by Ben.Marsh

	Move PumpMessages() into FPlatformApplicationMisc.

Change 3525399 by Ben.Marsh

	UGS: Use the default Perforce server port when opening P4V if there is not one set in the environment.

	UAT: Add a parameter to allow updating version files without updating Version.h, to allow faster link times on incremental builds.

Change 3525746 by Ben.Marsh

	EC: Include the clobber option on new workspaces, to allow overriding version files when syncing.

Change 3526453 by Ben.Marsh

	UGS: Do not generate project files when syncing precompiled binaries.

Change 3527045 by Ben.Marsh

	Fix hot reload generating import libraries without DLLs. Now that they are produced by separate actions by default, it was removing DLLs from the action graph due to the bSkipLinkingWhenNothingToCompile setting.

Change 3527420 by Ben.Marsh

	UGS: Add additional search paths for UGS config files, and fix a few cosmetic issues (inability to display ampersands in tools menu, showing changelist -1 when running a tool without syncing).

	Config files are now read from:

	Engine/Programs/UnrealGameSync/UnrealGameSync.ini
	Engine/Programs/UnrealGameSync/NotForLicensees/UnrealGameSync.ini

	If a project is selected:

	<ProjectDir>/Build/UnrealGameSync.ini
	<ProjectDir>/Build/NotForLicensees/UnrealGameSync.ini

	If the .uprojectdirs file is selected:

	Engine/Programs/UnrealGameSync/DefaultProject.ini
	Engine/Programs/UnrealGameSync/NotForLicensees/DefaultProject.ini

Change 3528063 by Ben.Marsh

	Fix non-thread safe construction of FPluginManager singleton. Length of time spent in the constructor resulted in multiple instances being constructed at startup, making the time to enumerate plugins on slow media significantly worse.

Change 3528415 by Ben.Marsh

	UAT: Remove \r characters from the end of multiline log messages.

Change 3528427 by Ben.Marsh

	EC: Fix spaces being converted to tabs at start of line in failure emails (by Gmail), and wrap following lines at the same indent.

Change 3528485 by Ben.Marsh

	EC: Remove zero-width word break characters from slashes in notification emails; can cause really hard to debug problems when copy pasted into other places.

Change 3528505 by Steve.Robb

Change 3528792 by Steve.Robb

	PR #3764: MallocProfiler - Refactoring Scopelock (Contributed by Josef-CL)


	#jira UE-46962

Change 3528941 by Robert.Manuszewski

	Fixed lazy object pointers not being updated for streaming sub-levels in PIE. Fixed lazy pointers returning object that is still being loaded which could lead to undefined behavior when client code started modifying the returned object.

	#jira UE-44996

Change 3530241 by Ben.Marsh

	UAT: Only pass -submit or -nosubmit to child instances of UAT if they were specified on the original command line. BuildCookRun uses this flag to determine whether to submit, rather than just whether to allow submitting, so we shouldn't pass an inferred value.

Change 3531377 by Ben.Marsh

	Plugins: Allow plugins to specify a list of supported target platforms, which is propagated to any .uproject file that enables it.

	This has several advantages over the per-module platform whitelist/blacklist:

	* Platform-specific .uplugin files can now be excluded when staging other platforms. Previously, it was only possible to determine which platforms a plugin supports by reading the plugin descriptor itself. Now that information is copied into the .uproject file, so the runtime knows which plugins to ignore.
	* References to dependent plugins from platform-specific plugins can now be eliminated.
	* Plugins containing content can now be unambiguously disabled on a per-platform basis (having no modules for a platform does not confer that a plugin doesn't support that platform; now it is possible to specify supported platforms explicitly).
	* The editor can load any plugins without having to whitelist supported editor host platforms.

	UE4 targets which support loading plugins for target platforms can set TargetRules.bIncludePluginsForTargetPlatforms (true for the editor by default, false for any other target types). This defines the LOAD_PLUGINS_FOR_TARGET_PLATFORMS macro at runtime, which allows the plugin system to filter which plugins to look for at runtime.

	Any .uproject file will be updated at startup to contain the list of supported platforms for each referenced plugin if necessary.

Change 3531502 by Jin.Zhang

	Add support for GPUCrash #rb

Change 3531664 by Ben.Marsh

	UBT: Change output format from C# JSON writer to match output by the engine.

Change 3531848 by Ben.Marsh

	UAT: Add script to resaving all project descriptors under a folder, embedding information for any supported platforms for the plugins they enable.

Change 3531869 by Ben.Marsh

	UAT: Add parameter to the ResaveProjectDescriptors command to update the engine association field.

Change 3532474 by Ben.Marsh

	UBT: Use the same mechanism as UAT for logging exceptions.

Change 3532734 by Graeme.Thornton

	Initial VSCode Support
	 - Tasks generated for building all game/engine/program targets
	 - Debugging support for targets on Win64

Change 3532789 by Steve.Robb

	FScriptSet::Add and TScriptMap::Add now replace the element, matching the behavior of TSet and TMap.
	Set_Add and Map_Add no longer have a return value.
	FScriptSet::Find and FScriptMap::Find functions are now FindIndex.
	FScriptSetHelper::FindElementFromHash is now FindElementIndexFromHash.

	Obsolete UHT settings deleted.

Change 3532875 by Graeme.Thornton

	VSCode
	 - Add debug targets for different target configurations

	 - Point all builds directly at UBT rather than the batch files
	 - Adjust mac build tasks to run through mono

Change 3532924 by Ben.Marsh

Change 3539691 by Graeme.Thornton

	VSCode - Various updates to get PC and Mac C++ projects building and debugging.
	 - Some other changes to C# setup to allow compilation. Debugging doesn't work.

Change 3539775 by Ben.Marsh

	Plugins: Various fixes to settings for enabling plugins.

	* Fix crash on startup when trying to disable a missing plugin (was keeping pointers to elements in the project's plugin reference array, which may be modified if a plugin is disabled).
	* Revert fix to set PluginDescriptor.bRequiresBuildPlatform = true by default. This was the originally intended behavior, but it was accidentally defaulted to false during serialization unless specified in the .uplugin file. Many plugins may rely on this behavior (they may not declare asset classes otherwise, for example, which could result in loss of data), so change the default value to false instead. Also fixes popups to disable platform-specific plugins if platform SDKs are not installed.
	* Fix plugins which are referenced but do not exist not showing the appropriate prompt to disable them.

Change 3540788 by Ben.Marsh

	UBT: Add support for declaring custom pre-build steps and post-build steps from .target.cs files. Similarly to the custom build steps configurable from .uproject and .uplugin files, these specify commands which will be executed by the host platform's shell before or after a build. The following variables are expanded within the list of commands before execution: $(EngineDir), $(ProjectDir), $(TargetName), $(TargetPlatform), $(TargetConfiguration), $(TargetType), $(ProjectFile).

	Example usage:

	public class UnrealPakTarget : TargetRules
	{
		public UnrealPakTarget(TargetInfo Target) : base(Target)
		{
			Type = TargetType.Program;
			LinkType = TargetLinkType.Monolithic;
			LaunchModuleName = "UnrealPak";

			if(HostPlatform == UnrealTargetPlatform.Win64)
			{
				PreBuildSteps.Add("echo Before building:");
				PreBuildSteps.Add("echo This is $(TargetName) $(TargetConfiguration) $(TargetPlatform)");

				PostBuildSteps.Add("echo After building!");
				PostBuildSteps.Add("echo This is $(TargetName) $(TargetConfiguration) $(TargetPlatform)");
			}
		}
	}

	#jira UE-47419

Change 3545976 by Ben.Marsh

	EC: Delete the AutoSDK client if the directory doesn't exist. When we format build machines, we need to force everything to be resynced from scratch.

Change 3546185 by Ben.Marsh

	Hacky fix for deployment on IOS/TVOS. Since deployment directly references the NonUFS manifest files that are written out, merge all the SystemNonUFS files back into the NonUFS list after the regular NonUFS files have been remapped.

Change 3547084 by Gil.Gribb

	Fixed a critical race condition in the new async loader. This was only reproducible on IOS, but may affect other platforms.

Change 3547968 by Gil.Gribb

	Fixed critical race which potentially could cause a crash in the pak precacher.

Change 3504722 by Ben.Marsh

	BuildGraph: Improved tracing for error messages. All errors are now propagated as exceptions, and are tagged with additional context information about the task currently being run.

	For example, throwing new AutomationException("Unable to write foo.txt") from SetVersionTask.Execute is now displayed in the log as:

	ERROR: Unable to write to foo.txt
	         while executing <SetVersion Change="0" CompatibleChange="0" Branch="Unknown" Promoted="True" />
	         at Engine\Build\InstalledEngineBuild.xml(91)
	       (see D:\P4 UE4\Engine\Programs\AutomationTool\Saved\Logs\UAT_Log.txt for full exception trace)

Change 3512255 by Ben.Marsh

	Rename FPaths functions with a "Game" prefix (GameDir(), GameContentDir(), etc...) to have a "Project" prefix (ProjectDir(), ProjectContentDir(), etc...) for clarity with non-game uses of UE4. Old functions still exist but are deprecated.

Change 3512332 by Ben.Marsh

	Rename "Game" functions in FApp to be "Project" functions (FApp::GetGameName() -> FApp::GetProjectName(), etc...) for clarity with non-game uses of UE4.

Change 3512393 by Ben.Marsh

	Rename FPaths::GameLogDir() to FPaths::ProjectLogDir().

Change 3513452 by Ben.Marsh

	Plugins: Rename EPluginLoadedFrom::GameProject to EPluginLoadedFrom::Project.

Change 3516262 by Ben.Marsh

	Add support for a "Mods" folder distinct from the project's "Plugins" folder, instead of using the bIsMod flag on the plugin descriptor.

	* Mods are enumerated similarly to regular plugins, but IPlugin::GetType() will return EPluginType::Mod.
	* The DLCName parameter to BuildCookRun and the cooker now correctly finds any plugin in the Plugins or Mods directory (or any subfolders).

Change 3517565 by Ben.Marsh

	Remove fixed engine version numbers from OSS plugins.

Change 3518005 by Ben.Marsh

	UAT: Remove the bUFSFile parameter from DeployLowerCaseFilenames(). Every platform returns false if the argument is false.

Change 3518054 by Ben.Marsh

	UAT: Use an enum to direct whether all directories should be searched when finding files to stage, rather than a bool. Having so many optional boolean arguments makes code unreadable and refactoring hard.

Change 3524496 by Ben.Marsh

	Start moving GUI application code into a separate static platform class, hopefully ultimately removing it from Core.

Change 3524641 by Ben.Marsh

	Move more functionality related to windowed/graphical applications into FPlatformApplicationMisc.

Change 3528723 by Steve.Robb

	MoveTemp now static asserts if passed a const reference or rvalue.
	MoveTempIfPossible still follows the old (std::move) rule, which is useful for templates where the nature of the argument is not obvious.
	Fixes to violations of these new rules.

Change 3528876 by Ben.Marsh

	Move FPlatformMisc::ClipboardCopy and FPlatformMisc::ClipboardPaste to FPlatformApplicationMisc::ClipboardCopy and FPlatformApplicationMisc::ClipboardPaste.

Change 3529073 by Ben.Marsh

	Add script to package ShooterGame for any platforms.

Change 3531493 by Ben.Marsh

	Update platform-specific plugins to declare the target platforms they support.

Change 3531611 by Ben.Marsh

	UAT: Add a ResavePluginDescriptors command, which resaves all plugin descriptors under a given folder, removing any outdated fields and rewrites them in a consistent style. Many plugins in the wild contain redundant or no-longer used fields due to using our plugins as templates.

Change 3531868 by Ben.Marsh

	Resaving project descriptors to remove invalid fields.

Change 3531983 by Ben.Marsh

	UAT: Simplify logic for staging code, and add validation against shipping files in restricted folders.

	* Added a new SystemNonUFS type for staged files, which excludes files from being remapped or renamed by the platform layer.
	* Replaced the DeplyomentContext.StageFiles() function with simpler overloads for particular use cases (options for remapping are replaced with the SystemNonUFS file type)
	* Config entries in the [Staging] category in DefaultGame.ini file allow remapping one directory to another, so restricted content can be made public in packaged builds (Example syntax: +RemapDirectory=(From="Foo/NoRedist", To="Foo"))
	* An error is output if any restricted folder names other than the output platform are in the staged output.

Change 3540315 by Ben.Marsh

	UAT: Moving StreamCopyDescription command into a NotForLicensees folder, since it's only meant to be used by engine developers.

Change 3542410 by Ben.Marsh

	UBT: Deprecate accessing properties through BuildConfiguration.* or UEBuildConfiguration.* from .target.cs files. These have been aliases to the current TargetRules instance for several releases already.

Change 3543018 by Ben.Marsh

	UBT: Deprecate the BuildConfiguration and UEBuildConfiguration aliases from the ModuleRules class. These have been implemented as an alias ot the ReadOnlyTargetRules instance passed to the constructor for several engine versions.

Change 3544371 by Steve.Robb

	Fixes to TSet_Add and TMap_Add BPs.
