  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

	Back out changelist 3870267

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

	Fixes a couple of regressions in DOF when using temporal upsampling.

	#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.

	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

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.

	Fixes a bug in DOF's temporal stability gathering pass.

Change 4057220 by Guillaume.Abadie

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

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

Change 4059478 by Mark.Satterthwaite

	It looks like FMetalCompiledShaderCache was misusing FRWScopeLock in ways that I can't believe even compiled - it looks like it ended up creating and destroying the scope-lock as a temporary rather than treating it as a block-local variable.

	#jira UE-58773

	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-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.

	AvfPlayer - support for streaming media.  Due to an operator new/delete mismatch in Apples CFNetwork - we've had to change out one of that framework allocators using rd_route to avoid  the memory corruption.

	DR - Fix OpenGL overwriting texture samplers on forward renderer

Change 3853945 by Mark.Satterthwaite

	Duplicate #3831616

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

	#jira UE-53720

Change 3853966 by Mark.Satterthwaite

	Duplicate #3835852

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

Change 3877428 by Krzysztof.Narkowicz

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

Change 3891925 by Yuriy.ODonnell

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

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

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

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

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

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.

	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.

Change 4030225 by Yuriy.ODonnell

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

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

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

	DR - Fix case with MVF where instance offset is not supported by the API (in this case only foliage OpenGL and TvOS), usually the buffers are offsetted instead but with MVF we do not use offsetted buffers, therfore the offset needs to be passed into the shader although we are drawing with offset of 0.

Change 3810277 by Daniel.Wright

	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.

	DR - Increased Intermediate normal of Umodel and Skelmesh from 8bit Unorm Compressed to float. A resave/rebuid/reimport of the meshes is recommended to recover some lost precision.
	Fixed an issue with compressed (packed) normals on the GPU which were off by one integer representation. Also switched from UNORM to SNORM to get a discrete zero representation and removed some mads from all the VertexShaders.

Change 3876607 by Rolando.Caloca

	DR - Use render passes when running occlusion queries

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

	DR - Change depth bounds so only the enable bit is in the PSO, allow min/max to be dynamically modified

Change 3964907 by Guillaume.Abadie

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.

	Fix for shader library not working with iterative cooking, also fixes native Metal library not working with iterative cook.  This works by saving a "backup" of the shader library file - this is reloaded only during iterative cook and adds back in shaders that are missing from the current cook.

	Fix for extracting/searching .metal files in different directories so debug tgz archiving wasn't working correctly and also support iterative cook.

	Includes first pass code review suggestions by Mark Sat and Dmitriy Dyomin.

Change 3839924 by Richard.Wallis

	Clone of CL 3838093

	Fix for rewind / seek bugs in AvfMediaPlayer.

	- Don't initialise and send audio buffers that have a duration of Zero from the audio tap.  This chokes the audio sink and adds overhead we don't need.
	- Don't faff around with current play rates during loop operation - normal seek doesn't do this so loop seek shouldn't either.
	- SetRate() should not required to be passed to media tracks - should be enough to do this on audio track select only.

	glTF: binary format's BIN chunk is not necessarily right after the JSON chunk.

	Discussed this with glTF spec authors. See https://github.com/KhronosGroup/glTF/issues/1177

	Rearranged how we read "chunks" from the file since they are not fixed in number or order, besides JSON always being first.

	glTF: base64 decoding of data buffers and images

	Data can be encoded inside the glTF JSON as a Base64 data URI. This CL addresses a known limitation of initial commit CL 3793018. I added this after because base64 is expected to be uncommon in the wild. Authoring software will typically use external BIN files (.gltf) or a BIN chunk (.glb) to store data.

	LLM update: Added Total, Untracked and FMalloc Unused to LLMFULL stat page. Fixed occasionally missing allocs/frees. Removed platform csv.

	* removed CheckSize arg from OnLowLevelFree
	* show a warning in LLM Map when replacing existing value. This means that there has been an alloc/free mismatch.
	* minor optimization in LLMMap::GetMaxIndex - cache Mask value
	* 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
	* fixed a bug in pausing where alloc/frees were being missed. Now only pauses a specific allocation type.
	* Trackers now maintain totals for each enum tag
	* tracking of Texture and mesh allocation on Windows D3D11 & D3D12

	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

	[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.

	 - 3735765 - Fix r.GTSyncType logic when vsync is disabled (falls back to old behaviour when vsync is off).

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 3822594 by Ben.Marsh

	UAT: Improvements to log file handling.

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

Change 3823695 by Ben.Marsh

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

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

Change 3823845 by Ben.Marsh

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

Change 3824180 by Ben.Marsh

	#jira UE-53813

Change 3829189 by Ben.Marsh

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

Change 3830444 by Steve.Robb

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

Change 3830718 by Ben.Marsh

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

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

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

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

Change 3833528 by Ben.Marsh

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

Change 3833543 by Ben.Marsh

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

Change 3834354 by Robert.Manuszewski

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

	#jira UE-52035

Change 3834400 by Robert.Manuszewski

	Fixing crash on exit caused by cached archetypes not being cleaned up before static exit cleanup.

	#jira UE-52035

Change 3834947 by Steve.Robb

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

Change 3835004 by Ben.Marsh

	Fix code that relies on dubious behavior of requiring referenced "include path only" modules having their _API macros set to be empty, even if the module is actually implemented in a separate DLL.

Change 3835340 by Ben.Marsh

	Fix errors making installed build from directories with spaces in the name.

	UBT: Fix ability to precompile plugins from installed engine builds.

Change 3837036 by Ben.Marsh

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

Change 3837037 by Ben.Marsh

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

Change 3837040 by Ben.Marsh

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

Change 3837247 by Ben.Marsh

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

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

Change 3837262 by Ben.Marsh

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

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

Change 3837343 by Ben.Marsh

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

	#jira UE-53996

Change 3839519 by Ben.Marsh

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

	UnrealPak: Log the size of all encrypted data

Change 3844258 by Ben.Marsh

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

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

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

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

	(Edigrating 3819174 to Dev-Core)

Change 3846439 by Ben.Marsh

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

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

Change 3816608 by Ben.Marsh

	UBT: Use DirectoryReference objects for all include paths.

Change 3816954 by Ben.Marsh

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

Change 3816986 by Ben.Marsh

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

Change 3816991 by Ben.Marsh

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

Change 3823090 by Ben.Marsh

	UAT: Improve logging for child UAT instances.

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

Change 3826082 by Ben.Marsh

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

Change 3827025 by Ben.Marsh

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

Change 3829927 by James.Hopkin

	Made HTTP interface const correct

Change 3833533 by Ben.Marsh

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

Change 3835826 by Ben.Marsh

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

Change 3835969 by Ben.Marsh

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

Change 3837777 by Steve.Robb

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.

	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).

Change 3540343 by Rolando.Caloca

	DR - Added t.DumpHitches.AllThreads

Change 3540661 by Yujiang.Wang

	Fix spot tube light direction

	* The tube direction for a spot light was pointing along the light direction, now it is along the local Z axis which is perpendicular to the light direction. Lightmass is also touched
	* 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

	* Bug caused by trying to share DrawRenderState between objects, but SetViewFlagsForShadowPass was designed to start from a fresh render state
	* Now SetViewFlagsForShadowPass recalculates and sets the flags on each call

Change 3542603 by Rolando.Caloca

	DR - vk - Allow sharing samplers on Vulkan

Change 3542639 by Jian.Ru

	In that case, we used the default settings for texture streaming (assuming a scale of 1).

Change 3543221 by Brian.Karis

	Simplifier optimizations

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).
	- The same problem has been resolved by bundling libc++.

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

	[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

Change 3548244 by Rolando.Caloca

	DR - Fix for translucency

Change 3548352 by Yujiang.Wang

	Added soft source radius for point and spot lights

	* 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 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

	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....

MAJOR FEATURES + CHANGES
==========================

Change 3148067 on 2016/10/01 by Daniel.Wright

	Support for ReflectionEnvironment and light type show flags with ForwardShading

Change 3149085 on 2016/10/03 by Daniel.Wright

	Support for ReflectionEnvironment show flag in base pass reflections without any shader overhead

Change 3162206 on 2016/10/13 by Chris.Bunner

	Merging Dev-MaterialLayers to Dev-Rendering, CL 3161593:
	Material expressions; Trig, fast-trig, saturate, round, truncate, pre-skinned normal.
	Added CustomEyeTangent to material attributes.
	Resolved some hard-coded attribute typing and other minor fixes.

Change 3186067 on 2016/11/03 by Daniel.Wright

	Updated Stationary primitive tooltip to indicate that it allows the primitive to be changed, but not moved

Change 3186069 on 2016/11/03 by Daniel.Wright

	Using a weighted geometric mean to combine multiple Distance Field Indirect Shadows, greatly reduces over-occlusion when overlap is high

Change 3186084 on 2016/11/03 by Mark.Satterthwaite

	Duplicate 3172511:
	Don't set Metal resource option fields on texture descriptors when running on an OS that doesn't support them.
	#jira UE-37481

Change 3186089 on 2016/11/03 by Mark.Satterthwaite

	Duplicate CL #3169764:
	Fixed automatic conversion of G8_sRGB into RGBA8_sRGB required for Mac Metal, which fixes FORT-27627.
	#jira FORT-27627

Change 3186113 on 2016/11/03 by Mark.Satterthwaite

	Duplicate CL #3183807:
	Change the way we access the Metal viewport's backbuffer, to reduce possible causes of FORT-31649:
	- Added console variable "rhi.Metal.SupportsIntermediateBackBuffer" to control whether to use an extra render-target so we can support screenshots & movie capture, or render directly to the back-buffer to save memory & GPU performance. Still defaults to ON for Mac & OFF for iOS/tvOS.
	- Change the way we handle updates to the back-buffer size to ensure that the different threads access their intended version.
	#jira FORT-31649

Change 3186116 on 2016/11/03 by Mark.Satterthwaite

	Duplicate CL #3183823:
	Record Metal resource & state objects used in a command-buffer when rhi.Metal.RuntimeDebugLevel is set to 3 or higher. The object labels, types & descriptions will be printed on failure - if the object is deleted prior to this then we have a lifetime error and it will crash at this point and can be debugged further using our -metalretainrefs command-line option or Xcode's zombie-objects.

	Used to verify that FORT-31649 is not a simple resource lifetime error and thereby speed up Apple/vendor investigations.
	#jira FORT-31649

Change 3207541 on 2016/11/22 by Ben.Woodhouse

	Cherry picked from //fortnite/Main@3207422

	* Fix UpdateTexture2D to only create a staging texture of the region to update, saving memory
	#jira UE-38609

	DR - vk - Fix some format issues

Change 3209265 on 2016/11/23 by Arne.Schober

	DR - originally unshelved from 3153924 - Made Depth and Velocity Rendering Passes to use PSO only RHI interface,
	We are now passing down two structs that collect all the necessary information for the drawing policies to construct a PSO object.
	One during construction of the Policy, which contains information abouyt the CullMode, FillMode and PrimType.
	And another during rendering that passes infomation like BlendState and DepthStencilState down to the low levelrenderer into SetSharedState.
	Performance of the static drawlist ist slightly slower (less than 0.1ms on Consoles) due to some addtional branches and copies. The branches in the FDrawingPolicyRenderState will go away as soon as everything is converted to use the PSO interface.
	Performace of the GPU is slightly better due to less context rolls (mainly CullMode sorts in differently now)

	Changes from UE4-DX12:

	*** CL 3183818 ***
	Update D3D12 RHI to 4.14:
	 - Merged changes from Epic up until 10/20/16
	 - Fixed an issue where command allocators where resetting too early. I changed to aggressive command list batching by default now that more SubmitCommandListHint calls exist in the upper engine, we don't need to worry about starving the GPU. Fewer ExecuteCommandLists calls means better performance and fewer Signals() so this change provides a GPU perf win.

	I had to fix an issue with aggressive batching where we would sometimes hold on to a command list long enough (in the pending list) but hadn't executed it yet. The command allocator was being put back in the queue of allocators during ReleaseCommandAllocator() without a syncpoint set and was thus being reset too early. I added a simple counter to the command allocator so it could track how many command lists were using it. It doesn't need to be thread safe since only one thread uses a command allocator at a time.

	I also added some stats around the # command lists and # command allocators since it would be possible to leak command allocators now if it's pending command list count isn't decremented correctly. In that case we'd keep creating new command allocators and eventually run out of memory.

	-Remove clear during allocate in the FD3D12FastConstantAllocator and FD3D12FastAllocator. The supplied resource locations are assumed to be new and thus don't need to be cleared.

	-Cleanup D3D12RHI stats. There were some unused stats as well as some missing ones.

	-Mark shader resource table uniform buffers as dirty only when the shader changes. Cleanup SetComputeShader calls and Dispatch calls to not set/unset the CS for each Dispatch.

	-Remove unused Check SRV resolved code that epic added to the D3D11 RHI and was brought over. We dont need it and we won't use this.

	-Remove "always on" cycle counters for high frequency RHI methods like RHISetShaderTexture. These should use the engine's stat macros as they are removed on TEST + SHIPPING builds. On Xbox a significant amount of CPU time is spent in things like QueryPerformanceCounter even when STATS aren't enabled. Currently 1% of an entire capture on XBOX is spent inside this call.

	I improved and cleaned up high freqency call stacks like:
	 - RHISetShaderTexture
	 - RHISetShaderResourceViewParameter
	 - RHISetShaderParameter
	 - RHISetUAVParameter

	In general I moved to use templated functions, removed unused parameters, unnecessary copies, etc.

	-Change D3D12 PIX profiling enable/disable to match Xbox and handle logic in the UEBuildWindows.cs for UBT. Also add a static assert to inform the developer when PIX profiling is requested but the engine is compiling out draw events.

	-Resources should be associated with the rendering thread's frame that it's currently recording command lists for and they shouldnt be cleaned up until those command lists have been translated to D3D12 command lists on the RHI thread AND completed executing on the GPU. This was confirmed to resolve an issue where CBV resources were being released too early.

	This work involved a couple changes:
	1) Move the "frame" fence to be incremented on the rendering thread (during RHIAdvanceFrameForGetViewportBackBuffer()) so that resources that are deleted from the rendering thread are assosicated with the correct frame count
	2) Queue up a command from the rendering thread to signal the "frame" fence. It needs to be queued to ensure that it's signaled at the correct time on the RHI thread (after that frame's command lists have been executed).

	-Disable GRHIRequiresEarlyBackBufferRenderTarget. Metal/Vulkan/Xbox11.x already do this. This is used by the Slate renderer during BeginRenderFrame and avoids a SetRenderTargets call.

	-Enable GRHISupportsMSAADepthSampleAccess (used in the Editor). This was enabled for D3D11 on SM5, but not for D3D12.

	-Delay load D3D12.dll and add root signature 1.1 support.

	-Add explicit flush calls to improve resource barrier batching instead of implict flushes inside FConditionalScopeResourceBarrier and FScopeResourceBarrier. Also update those classes with const members.

	*** CL 3183824 ***
	Fix the D3D12 RHI after integrating UE 4.14 updates:
	- Fixed a bug where we would try to get the PSO of a nullptr in SetPipelineState if we needed to reset the current PSO on the cmd list.
	- Fixed a spelling error
	- Removed the need for bForceState, we use dirty bits now

	*** CL 3183830 ***
	- GetDebugFlags RHI extension, needed by XB1 movie player.
	- Only query memory info if stats are enabled
	- Add support for the engine's new RHISubmitCommandsAndFlushGPU function
	- Update CommitPendingPipelineState to be Graphics/Compute specific and avoid the need for a IsCompute parameter.

	*** CL 3183837 ***
	Made PipelineState caches contain pointers to FD3D12PipelineState objects to avoid issues with using pointers to after Find/Add to the maps. TMap indicates that the pointer to the value associated with a key "is only valid until the next change to any key in the map." The lifetime of the PSO pointers is managed by the low level caches (graphics and compute). Added stat for the number of Pipeline State Objects.

	*** CL 3183931 ***
	Update Windows D3D12 headers and libs to RS1 release bits (10.0.14393.0)

	*** CL 3183978 ***
	Update UBT Windows build settings:
	- Change D3D12 PIX profiling enable/disable to match Xbox and handle logic in the UEBuildWindows.cs for UBT. Also add a static assert to inform the developer when PIX profiling is requested but the engine is compiling out draw events.

	-Delay load D3D12.dll and add root signature 1.1 support.

	*** CL 3184132 ***
	Fix Xbox PSO cache code where it could leak PSOs. Related to change 3183837.

	*** Changelist 3211714 ***
	Update D3D12 RHI with fixes:
	 - Check if we can reserve slots in GatherUniqueSamplerTables
	 - DirtyState more often in StateCache
	 - Remove InternalSetSamplerState. The alternate function isn't used.
	 - Allow MRTClear for arrays with holes in them
	 - Fix uninitialized descriptors. This was causing a GPU hang on Xbox. We need to set dirty bits for resources bound to slots outside of the current descriptor table's range
	 - Cleanup SetDescriptorHeap code. Move setting descriptor heap logic to the descriptor cache since it also owns things like the sampler maps. Added members to the descriptor cache to track the last heaps that were set on the command list to avoid dirtying bit unnecessarily.
	 - Resource transitions: go through Common between queues (3D <--> Compute)
	 - Fix initial state for placed resources.
	 - Merging epic

Change 3209340 on 2016/11/23 by Ben.Marsh

	Convert UE4 codebase to an "include what you use" model - where every header just includes the dependencies it needs, rather than every source file including large monolithic headers like Engine.h and UnrealEd.h.

	Measured full rebuild times around 2x faster using XGE on Windows, and improvements of 25% or more for incremental builds and full rebuilds on most other platforms.

	  * Every header now includes everything it needs to compile.
	        * There's a CoreMinimal.h header that gets you a set of ubiquitous types from Core (eg. FString, FName, TArray, FVector, etc...). Most headers now include this first.
	        * There's a CoreTypes.h header that sets up primitive UE4 types and build macros (int32, PLATFORM_WIN64, etc...). All headers in Core include this first, as does CoreMinimal.h.
	  * Every .cpp file includes its matching .h file first.
	        * This helps validate that each header is including everything it needs to compile.
	  * No engine code includes a monolithic header such as Engine.h or UnrealEd.h any more.
	        * You will get a warning if you try to include one of these from the engine. They still exist for compatibility with game projects and do not produce warnings when included there.
	        * There have only been minor changes to our internal games down to accommodate these changes. The intent is for this to be as seamless as possible.
	  * No engine code explicitly includes a precompiled header any more.
	        * We still use PCHs, but they're force-included on the compiler command line by UnrealBuildTool instead. This lets us tune what they contain without breaking any existing include dependencies.
	        * PCHs are generated by a tool to get a statistical amount of coverage for the source files using it, and I've seeded the new shared PCHs to contain any header included by > 15% of source files.

	Tool used to generate this transform is at Engine\Source\Programs\IncludeTool.

Change 3170391 on 2016/10/21 by Ben.Woodhouse

	Remove the wait on end of frame ensure, because we can't rely on all the the underlying codepaths to never miss a call to flush RHI resources. The consequences of missing a flush on a given frame are not serious now, since we enforce the synchronisation with a fence, preventing the rendering thread from getting too far ahead. We will simply accumulate resources for an additional frame when this happens.

	* New StaticMeshComponent properties bCastDynamicIndirectShadow and DynamicIndirectShadowMinVisibility
	* New WorldSettings property DynamicIndirectShadowsSelfShadowingIntensity which replaces the cvar
	* The GBuffer now stores HasDynamicIndirectShadowCasterRepresentation instead of HasHeightfieldRepresentation
	* DFAO from landscape is now done through the global distance field entirely.  Landscape contribution to the global distance field is deferred to attempt to workaround texture streaming issues.

Change 3163553 on 2016/10/14 by Mark.Satterthwaite

	Speculative fix for FORT-31590 also seen by a licensee - the Metal command buffer handler will be called from a dispatch queue thread that won't be registered with the stats system.
	#jira FORT-31590

Change 3163562 on 2016/10/14 by Mark.Satterthwaite

	Tidy up and extend the Metal debugging options:
	- Added rhi.Metal.BufferScribble which when enabled will fill freed buffer regions with 0xCD to help identify any areas where we are writing to a buffer while it is still being processed on the GPU.
	- Added rhi.Metal.BufferZeroFill which will zero-fill newly allocated buffer regions before any other data is read/written. Useful for catching cases where we might be reading uninitialised memory.
	- Added rhi.Metal.ResourcePurgeOnDelete which will purge the backing store of resources prior to releasing them back to the system or the respective pool. This will make any use-after-free conditions much more likely.
	- Added rhi.Metal.ResourceDeferDeleteNumFrames to defer releasing resources to the system or the resource pool by the specified number of frames (in addition to the current policy of waiting for the current end of frame & command-buffer completion). Useful for tracking down resource lifetime errors.
	- Fixed a number of bugs related to the modifications to vertex stream handling and addition of the SetShaderBytes API.
	- Track the start & end of FRingBuffer ranges - it appeared that the ring-buffer usage was invalid but it was in fact only my assumptions about the range that needed to be scribbled for rhi.Metal.BufferScribble. There is still the possibility that command-buffers that are implicitly parallelised by the driver may cause the ring-buffer range tracking to go awry - but with our data dependencies and the separation of the async. compute context I don't believe this is likely.
	- Fix up the "nometalv2" flag so that we can disable the features only available on iOS/tvOS-10/macOS-10.12 on newer devices to save having to reboot all the time.
	- Fixed the flickering geometry when enabling rhi.Metal.RuntimeDebugLevel=4 which breaks render passes into separate command-buffers - the occlusion query was waiting on the wrong command buffer in this case.

Change 3163752 on 2016/10/14 by Mark.Satterthwaite

	Add missing parenthesis to fix compile error on iOS.

Change 3164151 on 2016/10/16 by Benjamin.Hyder

	Submitting TM-AutoLOD level to QAGame

	#jira UE-29618

Change 3164190 on 2016/10/16 by Uriel.Doyon

	Materials now hold texture streaming data in the form of (UV scale X UV channel) for each texture.
	This data can be disabled through "r.Streaming.UseMaterialData"
	Defined a common framework in MeshComponent for texture streaming, used by both StaticMeshes and SkeletalMeshes.
	Simplified component interface for using the texture streaming build framework.
	Removed intermediate texture streaming build data from the static mesh components.
	Fixed shader compilation errors with the decals (from merge with main).

	DR - [OR-28457] Part1, Scene View Refactoring - Removed Previous VewMatrices from SceneInfo and pass in Previous and Current ViewMatrices into Uniform Buffer creation to uniform UseCase for Shadows and CustomDepth, Fixed a Bug in Shadows with help of Daniel where the SceneView was copied unnecessary copied again. Also simplified the code in that area.

Change 3164705 on 2016/10/17 by Daniel.Wright

	When new levels are loaded, only the Indirect Lighting Cache Allocations intersecting the level's light probes are updated to minimize hitches.  This optimization requires a lighting build to compute PrecomputedLightVolume bounds.

Change 3164834 on 2016/10/17 by Daniel.Wright

	Support directional light dynamic shadows in any channel with forward shading, which can happen with multiple shadow casting stationary directional lights (even though only the lighting of one will appear)

Change 3164870 on 2016/10/17 by Arne.Schober

	DR - [OR-28457] Part2, Custom Depth Jitter - Allowed to overwite the viewconstant buffer in the custom depth pass. There ia also a new Project Setting available. The default constructor of the ContextDataType has been explicitly deleted to enforce compile errors when the templated code like the StaticMeshDrawList accidently tries to create a context without ViewUniformBuffer.

MAJOR FEATURES + CHANGES
==========================

Change 3122543 on 2016/09/13 by Ben.Woodhouse

	Override HasOcclusion for Widget3DComponentProxy to detect if the material is has depth testing enabled.

	#jira UE-35878

Change 3122544 on 2016/09/13 by Ben.Woodhouse

	Shadow stencil optimisation with cvar (enabled by default)

	Avoids redundant clearing the stencil buffer for per-object and pre shadows by zeroing the stencil during testing, following discussion on UDN.

	This means we don't benefit from Hi Stencil on GCN for the shadow projection draw calls, but it's still faster in all the cases I could find, including for the player character where the bounding box is quite large. (Note: early stencil still works fine, according to PIX)

	Shadow projection GPU time profiling :
	Test map with 35 characters, stationary directional light
	  - 4ms-2ms on XB1
	  - 2.5ms to 0.9ms on PC (r9-390X)
	  - 3ms-2ms on PS4

	Paragon PS4 (roughly 20% reduced - from ~0.39ms)

Change 3125378 on 2016/09/14 by Arne.Schober

	DR - [UE-34481] - Extract all the State which is necessary to execute the DebugTextDrawingDelegate from the SceneProxy into its own Helpers to be drawn to the canvas later on. The issue was that the SceneProxys are only owned by the RT after their creation and the GT should avoid reading from or writing state to them.

	#review-3125887 @brian.karis

Change 3127130 on 2016/09/15 by Mark.Satterthwaite

	Add overloads to as* functions in hlslcc - HLSL allows you to call these on variables of the same type, in which case it simply returns the existing value but we had only defined the float<->u/int conversions, so hlslcc added implicit casts that broke such cases (i.e. asuint(uint) -> floatBitsToUint(float(uint))). This change defines the missing overloads as returns with regular casts.
	#jira FORT-25869
	#jira UE-34263

Change 3127475 on 2016/09/15 by Rolando.Caloca

	DR - vk - Debug dump

Change 3128131 on 2016/09/16 by Ben.Woodhouse

	(Integrated from //UE4/Private-Partner-NREAL/...)

	Alpha output support for postprocess materials (optional via a parameter)

	Needed for end of frame compositing. Could be used to pass intermediate data from one blendable postprocess to another (e.g edge detection)

Change 3128135 on 2016/09/16 by Ben.Woodhouse

	GPU profiler (PS4) - remove bubbles between commandlist submissions from query times

	Use r.ps4.AdjustRenderQueryTimestamps cvar to enable/disable (defaults to on)

	#jira UE-36072

Change 3128759 on 2016/09/16 by Mark.Satterthwaite

	Back out changelist 3127130 - its causing a build failure in FPostProcessVelocityScatterVS because hlslcc is picking the wrong as_* overload.

	Exposed full SceneCaptureComponent classes instead of select methods.
	#jira UE-35996

	DR - Avoid crash when adding dynamic primitives
	#jira UE-35327

	Improve vector noise tooltips & documentation

Change 3130547 on 2016/09/19 by Ben.Woodhouse

	Fix for ensure fail when initializing point light shadowmaps.

	This came about because cubemap rendertargets always have Extents of (Resolution, 0). The Y component was implicitly used to determine if it was a cubemap, which is odd... The fix was to make the definition explicit via a flag and initialize both the X and Y parameters.

	I suspect the ensure started happening recently due to a more recent change, but fixing the underlying logic seems like the correct fix.
	#jira UE-35837

Change 3130578 on 2016/09/19 by Daniel.Wright

	Workaround OpenGL/NVidia bug with non-power-of-2 textures by disabling CSM atlassing if we're using OpenGL

Change 3130682 on 2016/09/19 by Rolando.Caloca

	DR - Better fix for UE-35327
	#jira UE-35327

	Better handling of color array in VisualizeComplexity code to prevent assert.
	#jira UE-29332

Change 3130965 on 2016/09/19 by Arne.Schober

	DR - [UE-35679] - the crash was caused by the Resource of the UTexture being Null. And one of the Kismet Nodes calling a function on that resource. The solution was to disable that call from Kismet when only cooking.

Change 3130967 on 2016/09/19 by Chris.Bunner

	Hid redundant texture sampler properties from texture object parameter.
	Hid redundant texture property input on texture parameter nodes.
	Fixed copy-paste error in expression texture parameter docs.
	#jira UE-32724

Change 3131118 on 2016/09/19 by Mark.Satterthwaite

	Second attempt - this time with the correct input types. Add overloads to as* functions in hlslcc - HLSL allows you to call these on variables of the same type, in which case it simply returns the existing value but we had only defined the float<->u/int conversions, so hlslcc added implicit casts that broke such cases (i.e. asuint(uint) -> floatBitsToUint(float(uint))). This change defines the missing overloads as returns with regular casts.
	#jira FORT-25869

	#jira UE-35472

Change 3131228 on 2016/09/19 by Mark.Satterthwaite

Change 3131261 on 2016/09/19 by Mark.Satterthwaite

	Fix Metal validation failures due to particle rendering not binding buffers to all buffer inputs declared in the shader.
	ContentExamples Effects no longer aborts complaining that the particle system didn't bind a required buffer.

Change 3131265 on 2016/09/19 by Mark.Satterthwaite

	Fix FMetalDynamicRHI::RHIReadSurfaceData for shared textures on iOS.

Change 3131271 on 2016/09/19 by Mark.Satterthwaite

	Use private memory for the Metal stencil SRV workaround needed on El Capitan.

Change 3131273 on 2016/09/19 by Mark.Satterthwaite

	Disable the lazy-encoder construction in Metal for AMD - there is a situation that causes the lazy construction to perform a clear that isn't wanted and so far this hasn't been tracked down and fixed. Until then, this will render correctly.

Change 3131280 on 2016/09/19 by Mark.Satterthwaite

	For GLSL interpolation mode flags must come before storage mode flags and you can't redeclare the system variable gl_Layer to use a differing interpolation mode.

Change 3131283 on 2016/09/19 by Mark.Satterthwaite

	Change the ShaderCache to not cache resource bindings in the draw states for shader platforms that don't care - reduces the number of draw states considered significantly without reducing effectiveness. We can support ShaderCache with Metal SM5 but not the RHI thread enabled so change when we enable it and make sure we load the binary shader cache.

Change 3131506 on 2016/09/19 by Mark.Satterthwaite

	With permission from Josh.A & Michael.T, deprecate Mac OpenGL support. For now this just means visibly warning users with message boxes - but in a future release OpenGL support will be removed from macOS.

Change 3131536 on 2016/09/19 by Rolando.Caloca

	DR - vk - Compile fix

Change 3131564 on 2016/09/19 by Rolando.Caloca

	DR - vk - Submit Hint
	- Disable framebuffer recycling as its causing a hang

Change 3131625 on 2016/09/19 by Mark.Satterthwaite

	Inside MetalRHI add an optional cache for disposed texture objects so we may reuse them - controlled by CVAR rhi.Metal.TextureCacheMode which must be set prior to running as it can't be changed at runtime. Settings: 0 = off, 1 (default) = will attempt to reuse private memory texture objects within the frame they are released otherwise they are disposed of as before. Setting 2 extends the caching to all textures - though Managed/Shared textures cannot be reused until after the frame in which they were released has been processed on the GPU. In this mode id<MTLTexture> objects are never returned to the OS so in order to conserve VRAM calls to setPurgeableState are made to allow the driver to reclaim unusued memory if required.

Change 3131630 on 2016/09/19 by Mark.Satterthwaite

	More statistics in Metal added to track down where performance was going in a particular project but which may be more generally useful.

	#jira UE-35937

Change 3132696 on 2016/09/20 by Mark.Satterthwaite

	Use set*Bytes to handle uploading buffers < 4Kb when available - this is faster than lots of small Metal buffers and reduces the amount of GPU heap fragmentation. Where the API feature isn't available or hasn't been tested yet we'll use another ring-buffer inside the MetalCommandEncoder to emulate it.

Change 3132772 on 2016/09/20 by Mark.Satterthwaite

	Rework Metal's handling of RHISetStreamSource calls that override the stride of vertex declarations to be much more efficient.

Change 3132870 on 2016/09/20 by Ben.Woodhouse

	Fix mac compile error

Change 3133049 on 2016/09/20 by Brian.Karis

	Duplicate CL #3137164:
	Add stats to track exactly how many command buffers are allocated and committed each frame to work out why Fortnite on AMD is hanging, which turns out to be because each texture update/reallocation ends up in its own command-buffer. This needs to be rethought to pack these into fewer command buffers with the same synchronisation requirements to minimise command-buffer splits but for now we'll just make the default sufficiently large that we shouldn't see the hang until the work is done. Also ensure that command-buffer failure is always fatal - there is no way to recover or continue if a command-buffer fails.

Change 3140360 on 2016/09/26 by Daniel.Wright

	Lighting Scenarios and lightmaps moved to separate package
	* Levels can be marked as lighting scenarios (eg Day, Night).  Lighting is built separately for each lighting scenario with actors / lights in all other scenario levels hidden.  Only one lighting scenario level should be visible at a time in game, and its lightmaps will be applied to the world.
	* Most outputs of the lighting build now go into a separate _BuiltData package.  This improves level Save and AutoSave times as the separate package will only be dirtied after lighting rebuilds.
	* If a lighting scenario is present, all lightmaps are placed inside it's _BuiltData package.  This means that only the currently loaded lighting scenario's lightmaps will be loaded (Day or Night, but not both).  This also means that lightmaps for a streaming level will not be streamed with it.
	* For backwards compatibility, existing lightmaps are moved to a new _BuiltData package on load.
	* Reflection captures and precomputed visibility were not moved to the separate package.  Reflection captures are force updated on load of a lighting scenario level, which can increase load times.

The order of initialisation is different per-platform:

The reasoning behind this was that it will be auto disabled when Skincache Shaders are disabled, and runtime toggle is a debuging feature that mainly programmers are dealing with. The Recompute Tangents option in the Skinned Mesh is now automatically grayed out when no Skincache Shader Permuations are available.

	The density are computed by the engine but can be overridden by the user in the material tabs.

	Texture streaming intermediate component data is now per material instead of per lod-section.

	New ViewModeParam in FSceneViewFamily allowing context specific param per viewmode.
	This is currently used to show which UV channel and which texture index is being
	shown in the texture streaming accuracy viewmodes.
	This replaces r.Streaming.AnalysisIndex

	Renamed texture streaming viewmodes:
	MeshTexCoordSizeAccuracy -> MeshUVDensityAccuracy
	MaterialTexCoordScalesAccuracy -> MaterialTextureScaleAccuracy
	MaterialTexCoordScalesAnalysis -> OutputMaterialTextureScales

	DR - Refactoring of the ViewMatrices. Moved the Derived Matrices into the FViewMatrix struct. Made all members private do emphasize the static constness of that struct after creation. Renamed the heavy weight members on this struct to Compute*. Methods that modify The ViewMatrices have been renamed to Hack* to discurage their use in the future until a better solution for those problems is found. The ViewMatrix modification is especially misleading because it only changes the State of the ViewMatrices to read their Position from the Material Editior as if coming from the Lightsource (mainly for manual bilboards) as well as doing someting similar to generate CPU bilboards for shadows.

MAJOR FEATURES + CHANGES
==========================

Change 3091951 on 2016/08/17 by Chris.Bunner

	(Duplicate) CL 3090919: Fixed edge case interactions in HLOD ray rejection logic in Lightmass.

Change 3093162 on 2016/08/18 by Ben.Woodhouse

	Fix minor memory leak (missing delete of RT Heartbeat thread)

Change 3093470 on 2016/08/18 by Ben.Woodhouse

	Fix minor leak in FMonitoredProcess - the Thread member would get leaked if the FMonitoredProcess was cancelled, because it gets NULLed without deleting it.  Fix is to add a bool to keep track of whether the thread is running, rather than using the Thread pointer.
	Also fixes a race condition where the FMonitoredProcess::Thread member could get initialized after the thread had completed. This would cause IsRunning to never return false, even if the thread has completed, and the editor would hang on startup (this was fixed by setting bIsRunning to true before creating the thread)

Change 3093698 on 2016/08/18 by Daniel.Wright

	Translucent lighting volume draw event cleanup

Change 3093700 on 2016/08/18 by Daniel.Wright

	Clamp on box reflection capture transition distance visualizer

Change 3093755 on 2016/08/18 by Ryan.Vance

	Merging stereo planar reflections from Odin.

Change 3094060 on 2016/08/18 by Daniel.Wright

	Fully featured base pass reflection captures with blending and parallax correction
	* Used in the forward renderer when materials opt-in to 'High Quality Reflections'
	* Used in the deferred renderer for translucent 'Surface ForwardShading' materials
	* Reflection captures are culled to a frustum space grid using the same reverse linked-list method as lights in the forward renderer
	* Fixed grid culling in stereo / splitscreen
	* The ReflectionEnvironment compute shader used in the deferred path also uses the culled grid now which reduces its cost from .93ms -> .70ms on 970 GTX.  PS4 cost is about the same.
	* Capsule indirect self-shadowing is now reduced in the forward path to match deferred, and both are controlled by r.CapsuleIndirectShadowSelfShadowIntensity
	* SetupHZB is now skipped when SSAO / SSR / HZB are all disabled

Change 3094160 on 2016/08/18 by Daniel.Wright

	CIS fixes

Change 3094899 on 2016/08/19 by Ben.Woodhouse

	Batching optimization for dragging components onto blueprints, reported on UDN. Adding 2300 static mesh actors now takes 3 seconds instead of 40 minutes.
	https://udn.unrealengine.com/questions/305821/suspected-rhi-uniform-buffer-leak-when-adding-stat.html

	DR - Custom Renderer callback after getting SceneColor

Change 3098418 on 2016/08/23 by Olaf.Piesche

	Moving vertex factory dirtying to always happen in-editor for mesh emitters on dynamic data reinitialization; there are several cases in which this needs to happen (some material changes, mesh reimports...) which are difficult to track, so in-editor we just always recreate the mesh particle vertex factory with the dynamic data.

	#jira UE-34838

Change 3098448 on 2016/08/23 by Rolando.Caloca

	DR - vk - fixes for depth/stencil descriptors
	- Minor debug dump improvement

Change 3098463 on 2016/08/23 by Daniel.Wright

	Static lights with MinRoughness = 1.0 don't get their source shapes drawn into reflection captures, since they are being used as virtual area lights

Change 3098556 on 2016/08/23 by Daniel.Wright

	Lightmass area shadows only mark texels as mapped inside the light's influence, which fixes multiple stationary lights with bUseAreaShadowsForStationaryLight interfering.

Change 3098672 on 2016/08/23 by Rolando.Caloca

	DR - vk - Fixed crash when using vertex shaders with no descriptors

Change 3099173 on 2016/08/24 by Ben.Woodhouse

	Fixed various issues with subsurface profile, for checkerboard and non-checkerboard code paths

	- Re-enable non-checkerboard skin by default

	- Checkerboard issues fixed:
	    - Emissive lighting was being applied twice due to not taking checkerboard pattern into account
	    - Emissive lighting was modulated by basecolor in the recombine
	    - Metallic materials were contributing specular lighting to the diffuse channel

	 - Non-checkerboard fixes:
	    - Fix write mask during SkyLightDiffuse so alpha is updated correctly
	    - Metallic specular lighting was broken (specularColor was lerping to white instead of baseColor)

	 - Optimisation: Fall back to default lit for pixels where the opacity is 0.
	    - For non-checkerboard, this gives better handling of metallic/emissive for pixels where SSS is not required (non-CB RGBA encoding for diffuse/spec doesn't cope well with colored specular or emissive)
	    - For checkerboard, this gives similar results in terms of shading, but we get full-resolution shading on non SSS pixels

	#jira UE-34561

Change 3099673 on 2016/08/24 by Daniel.Wright

Change 3099674 on 2016/08/24 by Daniel.Wright

Change 3099789 on 2016/08/24 by Brian.Karis

	FloatRGB  is now always supported.

	If 11:11:10 isn't supported by hardware this format by definition will map to a different format meaning it is always supported.

Change 3099987 on 2016/08/24 by Daniel.Wright

	Fixed light grid debug asserts on PS4
	* Always creating the local light buffer, even if it won't be used by the shader
	* Transition ViewState FRWBuffers to writable at the beginning of a new frame
