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

Change 3358140 on 2017/03/22 by Rolando.Caloca

	DR - Fix copy to cube face
	- Compile fix when using dump layer
	- Add new error enum

Change 3358301 on 2017/03/22 by Mitchell.Wilson

	Initial check in of LODs in InfiltratorForward. First pass on optimization in level. Adding a visibility track for SceneCapture2D in tunnel section.

Change 3358477 on 2017/03/22 by Mitchell.Wilson

	Updating Skeletal Mesh DPW_Robot_Export to resolve screen size being too low for LOD1. Cleaned up LOD1 which was showing some visible popping when transitioning.

Change 3358529 on 2017/03/22 by Mark.Satterthwaite

	Globally disable clang's "constant-logical-operand" warning when running under Distcc - it is much easier and less invasive than constantly fixing the code.

Change 3358745 on 2017/03/22 by Mark.Satterthwaite

	Disable another warning (parentheses-equality) under Distcc because again the separation of preprocessing from compilation means it turns up where it isn't expected.

	* Planar reflections are now supported in splitscreen

Change 3360758 on 2017/03/23 by Daniel.Wright

	[Copy] Added new light property bCastVolumetricShadow, which defaults to true for directional and sky lights, but false for point / spot lights as supporting volumetric fog shadowing has significant GPU overhead

Change 3360762 on 2017/03/23 by Daniel.Wright

	[Copy] Texture flags are now properly routed to RHICreateTexture3D from the render target pool

	[Copy] Distance field cvar comments

Change 3360782 on 2017/03/23 by Daniel.Wright

	[Copy] Disabled selection color on Volume materials

Change 3360795 on 2017/03/23 by Daniel.Wright

	[Copy] Volume materials now specify Albedo and Extinction, which is more intuitive than Scattering and Absorption.  Albedo is [0-1] reflectance, while Extinction is a world space density.

Change 3360799 on 2017/03/23 by Daniel.Wright

	[Copy] Cinematic scalability levels get 2x volumetric fog resolution in x and y

Change 3360806 on 2017/03/23 by Daniel.Wright

Change 3360809 on 2017/03/23 by Daniel.Wright

	[Copy] Volumetric fog now adds a bias to the inverse squared light falloff denominator, prevents extreme aliasing from the hotspot.  Can be controlled with r.VolumetricFog.InverseSquaredLightDistanceBiasScale.

	Volumetric fog supports static shadowing from Stationary lights
	* Using bilinear on static shadowmap depths + 1 PCF to smooth out results

Change 3366029 on 2017/03/27 by Daniel.Wright

	Static shadow depth maps for Stationary point and spot lights are 2x higher res by default (4x more texels), which is more appropriate for volumetric fog

	Missed a file.

Change 3367838 on 2017/03/28 by Richard.Wallis

	Updated items from original shelved version by Mark Satt:

	- Added MetalBackend.cpp to change main function string to have an initial crc + code length zero's

	**Description below taken from Mark Satt's original verison of this in CL3343280**

	Updated for Dev-Rendering's PSOs & integrates Richard's work on RHI shader libraries.

	Replace the FShaderCache's cook-time binary shader cache with Dmitriy Dyomin's standalone FShaderCodeLibrary that saves all shader byte-code arrays to files named by the FSHAHash. This de-duplicates shaders so we only ever store the byte code once. Includes optional support for generating a platform specific library file - which Metal implements to provide a single Metal library. The platform-native implementation can perform more de-duplication and in the case of Metal has lower file overheads and will compress more efficiently.

	- All of the support code for the FShaderCache's cook caching is gone, which affects all platforms. The FShaderCodeLibrary is currently  supported by Cook-By-The-Book but can be used with iterate or child cookers - only DLC cooking requires further work.
	- With further modifications it should be possible to support Cook-on-the-Fly as well (output directories would be needed in FShaderCodeLibrary::InitForCooking) and the file-access pattern should be changed to use async. IO so that Material loading is not considered complete until all required byte-code arrays are loaded into the FShaderCodeLibrary.
	- For Metal archiving shaders this way will compile with debug information and the FShaderCodeLibrary, with some help from extensions to IShaderFormat, will save the debug information out into separate files during cooking - these can then be used to debug the game without having to locally recompile, recook & repackage but the shipped byte-code is stripped. Global shader caches are also subject to de-duplication in the library in order to support Metal's shader stripping.
	- File Move operations need to respect the 'Replace' flag - for FShaderCodeLibrary to work we need Move to be atomic.
	- This bumps the object version and will cause all content to recook.
	- Native library support is optional - only Metal currently implements one, but so could Vulkan and D3D12. For Metal the big advantages are further de-duplication where different materials generate the same MetalSL text but a different FSHAHash, that the single Metal library has lower overhead and that as a single file it all compresses far better (esp. with LZMA - 5x smaller).

Change 3367854 on 2017/03/28 by Mark.Satterthwaite

	Don't track or record draw call resources for non-OpenGL shader platforms in the shader-cache as it is unnecessary and makes it slower on the CPU than it needs to be.

Change 3367877 on 2017/03/28 by Brian.Karis

	Fixed linux build hopefully

Change 3368001 on 2017/03/28 by Mark.Satterthwaite

Change 3368019 on 2017/03/28 by Mark.Satterthwaite

	And another fix for Windows compilation of MetalShaderFormat.

Change 3368042 on 2017/03/28 by Mark.Satterthwaite

	Remove temp working directories after archive packages built.

Change 3371641 on 2017/03/30 by Rolando.Caloca

	DR - Copy 3371640 (fix mem leak)

Change 3372436 on 2017/03/30 by Uriel.Doyon

	Added flags in UPrimitiveComponent to keep track of its state in the streaming manager.
	This allows to avoid unnecessary callback and processing in begin destroy reattach and being destroy logic.

	Removed the limitation of only processing UMeshComponent when handling spawed primitive.
	This releases the level manager from having to manage dynamic primitives.
	This improves performance by not having to manage dynamic references in the level manager.

	Primitives managed as dynamic now have a callback when ever their proxy is udpated, handling
	many cases automatically where previously a manual callback to notify would have been required.

	Fixed an issue where primitives with no reference to streaming textures would loose they dynamic state
	because of lack of references in the streamer.

Change 3372740 on 2017/03/30 by Chris.Bunner

	[Experimental] Partial compute post process pipeline (r.PostProcess.PreferCompute).
	StencilSceneTexture added to deferred list.
	A few known issues to be fixed in a follow-up CL.

Change 3372765 on 2017/03/30 by Uriel.Doyon

	LPV Fade support
	- mostly integrated from CL 2959511

Change 3373272 on 2017/03/30 by Uriel.Doyon

	Refactored common param code to shared sub-class in CombineLUTs and Tonemap PS/CS.
	Skip compute post process out-of-bounds writes.
	Unsigned type conversion fixes.
	Trimmed compute post process shader inputs.

Change 3374233 on 2017/03/31 by Chris.Bunner

	Removed several redundant post process compute fences and resource transitions.
	Added testing CVar to force compute post processes to async (r.PostProcess.ForceAsyncDispatch).

Change 3374412 on 2017/03/31 by Rolando.Caloca

	DR - Fix static analysis

Change 3374544 on 2017/03/31 by Richard.Wallis

	FShaderCache Parallel-Context-Aware Merged with FShaderCache Single Library.

	Future Work
	- This was done before Engine PSO were in so this now needs a refector in the recording and playback on pipeline states instead an emulate PSO in OpenGL Driver.
	- Remove FShaderCacheState and replace the logic with FGraphicsPipelineStateInitializer which should be able to record from the RHI current pipeline state
	- This would reduce the Locking required as it's naturally per thread/context and only the final record would need a lock

	Copying Metal improvements from task stream, with some modifications:
	- Off-by-default implementations for MTLFence & MTLHeap, including some small changes to the RHI interface for parallel contexts.
	- Support for Apple's Instruments "Points of Interest" tool.
	- Consolidation of some Mac & iOS compiler, memory and thread handling code.
	- Fixes for Metal not having implicit buffer SRV typecasting for DistanceField effects.
	- Improvements to the internal FMetalDebug layer, still off by default.
	- Limited support for Xcode automatic code-signing for iOS/tvOS.
	- Minimisation of render-target changes in some rendering code, esp. SceneOcclusion, DBufferDecals.
	- Added RHISetResourceAliasability_RenderThread to FDynamicRHI for RHIs to implement simple render-target aliasing.
	- Added FApplePlatformObject, a custom block allocator for Objective-C types (with NSZombie support) which is now used in MetalRHI to decrease allocation costs of Objective-C types.
	- Smattering of lesser fixes.

Change 3375654 on 2017/03/31 by Mark.Satterthwaite

Change 3376756 on 2017/04/03 by Guillaume.Abadie

	Fixes scene captures ordering's backward compatibility.

	Before, 2d scene captures were rendered before cube scene captures. The CaptureSortPriority broke backward compatibility by settings this new member to 0 in the USceneCaptureComponent's constructor. Since it is a higher come first policy, this CL set the default of this value to 1 in USceneCaptureComponent2D's constructor.

	Partial code tidy up.

Change 3310187 on 2017/02/17 by Chris.Bunner

	Preserve constant expressions rather than always casting after translating a material attribute. Losing the notion of constant means we can't correctly detect used properties and falsely enable e.g. PDO. Happened because of the incorrect component masks in BreakMaterialNodes which then had to be downcast to the correct type which is done as an inline fragment rather than swizzle expression.

	#jira UE-41594

Change 3310215 on 2017/02/17 by Chris.Bunner

	[Copy] Added 'r.AOListMeshDistanceFields' which dumps out mesh distance fields sorted by memory size, useful for directing content optimizations

Change 3333705 on 2017/03/06 by Daniel.Wright

	[Copy] Mesh distance fields are now 8 bit fixed point by default, but can be changed back to 16 bit floating piont with a project setting.
	* 8 bit uses half memory but introduces error for thin surfaces or large meshes.

Change 3333721 on 2017/03/06 by David.Hill

	DecalProxy:
	Copy float FadeScreenSize to FDeferredDecalProxy for use in the render thread.  This avoids  pointer chasing to the UDecalComponent (game thread component).

Change 3333772 on 2017/03/06 by Daniel.Wright

	[Copy] Scene motion blur data is only updated for the main renderer frames.  Fixes scene captures and planar reflections breaking object motion blur.

Change 3333790 on 2017/03/06 by Daniel.Wright

	Non-editor compile fix

Change 3333836 on 2017/03/06 by Daniel.Wright

	[Copy] Workaround for gobal distance field volume textures being bloated by 4x on PS4 due to the recommended tiling modes.  They now use a 2d tiling mode which avoids the bloat, saving 96Mb.

Change 3333869 on 2017/03/06 by Daniel.Wright

	[Copy] Volumetric Fog using a volume texture mapped to the camera frustum
	* Volumetric fog can be enabled on an Exponential Height Fog component with additional controls
	* Lights have a VolumetricScatteringIntensity
	* New cvars r.VolumetricFog, r.VolumetricFog.GridPixelSize, r.VolumetricFog.GridSizeZ, r.VolumetricFog.DepthDistributionScale
	* Lighting features supported:
	   * Directional light with CSM and a light function
	   * Point / spot lights without shadows / light functions / IES profiles
	   * Skylight with occlusion from distance fields
	* Analytical height fog covers the view range past where the volumetric fog ends
	* Temporal reprojection is used on the volumetric fog scattering and extinction to achieve stability
	* Translucency integrates properly into volumetric fog
	* Height fog StartDistance is not supported by volumetric fog and should be set to 0.

Change 3333894 on 2017/03/06 by Daniel.Wright

	[Copy] Initialize GDummyVolumetricFogGlobalDataUniformBuffer outside of parallel rendering

Change 3333902 on 2017/03/06 by Daniel.Wright

	[Copy] Fixed volumetric fog trying to render light functions for a point light

Change 3333908 on 2017/03/06 by Daniel.Wright

	[Copy] Volumetric materials
	* Added new material domain Volume, which can output Scattering, Absorption and Emissive.  All properties are in world space densities.
	* Particle systems using the Volume domain are voxelized based on their ParticlePosition and ParticleRadius
	* Volumetric fog integration is now energy conservative - scattering is integrated against transmission over the depth of each slice.
	* Added bOverrideLightColorsWithFogInscatteringColors to exponential height fog, which can be enabled to make Volumetric Fog match Height fog more closely

Change 3334134 on 2017/03/06 by Daniel.Wright

	[Copy from Michael Trepka] Added Embree 2.14.0 and changed MeshUtilities to use it as this solves issues with Embree leaking TLS keys. UnrealLightmass is still using older Embree 2.7.0 until we can find time to properly test it with the new version. Also, invalidated distance field DDC to force it to rebuild with updated Embree.

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

Change 3232283 on 2016/12/13 by Ben.Woodhouse

	D3D12 - downgrade root signature size warning to a log following a discussion with Microsoft. There's not much we can actually do about it, and it's not relevant to all hardware
	#jira UE-36999

Change 3232641 on 2016/12/13 by Mark.Satterthwaite

	- Eliminate redundant state changes in MetalRHI in the state cache.
	- Add a new debug level for setting buffers to nil prior to calls to set*Bytes so that the tool doesn't display incorrect data.
	- Make testing for validation & statistics features use the same EMetalFeatures API as everything else for consistency.
	- Cache the fallback depth-stencil texture in the state cache and ignore it for determining whether a pass can restart - if we are using this texture its contents are worthless anyway.

Change 3232661 on 2016/12/13 by Mark.Satterthwaite

	Re-enable Metal SM5 & DFAO/DistanceFieldShadowing on Intel for 10.12.2 or later.

Change 3232759 on 2016/12/13 by Ben.Woodhouse

	Fix memory leak on XB1 when calling GPURealloc with count of 0, suggested on UDN
	https://udn.unrealengine.com/questions/326660/gpurealloc-leak.html

Change 3232803 on 2016/12/13 by Ben.Marsh

	Add UT to the populate DDC job, and cook UT and Fortnite for Mac as well.

Change 3232836 on 2016/12/13 by Ben.Marsh

	Split cooks to populate DDC into separate nodes for each platform. May help to reduce number of timeouts on remote VMs.

Change 3232974 on 2016/12/13 by Rolando.Caloca

	DR - Refactor common code to UWorld::RecreateScene
	#jira UE-36719
	PR #2824

Change 3232976 on 2016/12/13 by Ben.Marsh

	Add missing dependency on tools node for Mac cooks. Need to compile SCW first.

Change 3233289 on 2016/12/13 by Olaf.Piesche

	Fixing potentially broken spot/point light fade with old content; initialize new properties properly

Change 3233811 on 2016/12/13 by Mark.Satterthwaite

	Fix compiling QA-Material tessellation shaders that don't need to emit from Hull or sample in Domain the HSOut buffer which was confusing MetalBackend.

Change 3233854 on 2016/12/13 by Mark.Satterthwaite

	More information about texture type validation errors in Metal.

Change 3234650 on 2016/12/14 by Rolando.Caloca

	DR - vk - Fix bad aspect on depth cubemaps

Change 3234651 on 2016/12/14 by Rolando.Caloca

	DR - vk - Fix for 32 bit crash on dump layer

Change 3234813 on 2016/12/14 by Guillaume.Abadie

	Fixes texture mask static lighting when using GBuffer selective outputs.

	#jira UE-39527

Change 3235047 on 2016/12/14 by Uriel.Doyon

	Refactored HLOD texture streaming strategy to separate forced load from visibility.
	Added an incremental update in the last stage of the texture streaming update load to clear any pending work.
	Added an option "All" to the "BuildMateriaTexturelStreamingData" command to force rebuild everything.

Change 3235317 on 2016/12/14 by Uriel.Doyon

	Removed timed primitives in the texture streaming since it was not used and there is now a fallback implementation in UPrimitiveComponent::GetStreamingTextureInfo.

Change 3235431 on 2016/12/14 by Rolando.Caloca

	DR - Fix for Vulkan drawing black

Change 3236788 on 2016/12/15 by Mark.Satterthwaite

	Fix 10.11.6 support (aka -nometalv2): the stencil view workaround necessitates a mid-render blit and the way things were setup resulted in the HasValidRenderTargets assert firing. Refactored the code to separate the concept or valid render-states in the cache from active render-states in the render-pass. Now it works as intended and will be needed for 4.15.

Change 3236850 on 2016/12/15 by Mark.Satterthwaite

	Make changing the Metal Shader Version project setting prompt the user to restart for the changes to take effect.
	#jira UE-39801

Change 3237002 on 2016/12/15 by Benjamin.Hyder

	submitting updated TM-Shadermodels map

Change 3237312 on 2016/12/15 by Rolando.Caloca

	DR - Change more macros to lambdas

Change 3237394 on 2016/12/15 by Mark.Satterthwaite

	Add Metal-specific permutations of TBasePassHS - they affect the C++ definition on all platforms but are only cached or used on Metal - because the way we compile the combined VS+HS tessellation stage requires that the combined VS + HS HLSL code references the same resources, otherwise we get incorrect resouce bindings and subsequently fail to render properly. Long-term the Metal tessellation code will need to be refactored so that the vertex shader stage is emitted as a separate shader from the hull shader stage as this but will keep cropping back up and continue to complicate the engine.
	#jira UE-39799

Change 3237490 on 2016/12/15 by Daniel.Wright

	Fixed ULandscapeComponent::GetUsedMaterials

Change 3237597 on 2016/12/15 by Ben.Woodhouse

	Disable timestamp queries on pre-Maxwell nvidia hardware. Local testing suggests that this is the major cause of instability in the UE4.14 release.

	It's possible that we could be more targeted by only excluding Fermi and older hardware, but identifying fermi hardware by device ID is difficult in practice, since the range overlaps with Kepler.

Change 3237654 on 2016/12/15 by Daniel.Wright

	Replace TEA random number generator with PCG.

	Was only used in #if-disabled reference rendering, but ldoes make better quality reference rendering when enabled.

Change 3238496 on 2016/12/16 by Marc.Olano

	Tone mapping fix for OR-31752, cherry picked from Orion 3208273

	Assumption that green is approximates luminance fails on red/blue HDR content, resulting in ugly black artifacts. Go back to luminance.

Change 3238520 on 2016/12/16 by Rolando.Caloca

Change 3240163 on 2016/12/19 by Daniel.Wright

	Distance field self shadowing controls for hiding world position offset self-shadow artifacts
	* Removed static mesh build settings DistanceFieldBias, which shrunk the distance field, breaking AO and shadows
	* Added DistanceFieldSelfShadowBias, which prevents occlusion close to the surface only, maintaining shadows on the ground and AO on the ground

Change 3240271 on 2016/12/19 by Daniel.Wright

	Use 16 bit indices for distance field objects culled to tiles, when 16 bit will be enough.  Saves 10mb of tile culling buffers.

==========================
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

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

Change 3207654 on 2016/11/22 by Chris.Bunner

	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)

Change 3209305 on 2016/11/23 by Guillaume.Abadie

	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

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

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 3122543 on 2016/09/13 by Ben.Woodhouse

	#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)

	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.

	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.

	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.

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.

	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:

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.

	#orion - Lower default NetUpdateFrequency for minions (10->6). Avoid excessive latency for some knockback/knockup abilities that would have noticeable lag by forcing an update sooner when they are triggered.

	This should have the following effects:
	1. Reduce server CPU cost (we tick minions at the net frequency).
	2. Reduce server bandwidth
	3. Reduce client CPU cost (we move character capsules and perform overlaps when new positions are received).

Change 2946645 on 2016/04/18 by Richard.Fawcett

	When promoting a buidl to staged, prevent enumeration of files already in S3

	Enumerating files in S3 is a slow process, and it turns out that simply uploading all chunks blindly is more efficient than enumerating existing chunks and selectively uploading only the new ones.

	#rb Leigh.Swift
	#tests This technique has already been used in launcher promotions for several months

Change 2946622 on 2016/04/18 by Richard.Fawcett

	By default, when enumerating chunks from a manifest file, skip checking they exist on disk at enumeration time.

	This will fail anyway further down the line if the files don't exist, but will improve speed of stage promotions by around five minutes. In practice, we have NEVER seen a job fail at this point because of the existence check.

	#rb Leigh.Swift
	#tests Ensure that output of ExtractDataFilenamesFromManifest method is identical both with and without bSkipExistsCheck specified.

	Fix for OR-19778

	When some pooled systems are reused, on init they have a non zero lod level but the emitter instances are created at LOD 0 initially.
	So the component did not think it had to update it's LOD but the emitters were not at the correct LOD.
	Have forced a LOD set on init when the component LOD is non-zero.

Change 2943174 on 2016/04/13 by Aaron.McLeran

	OR-19392 Ensure condition failed: (*RequiresInitialization == 0) on loading into PVP match

	- Removing ensure since there is a rare edge case where it's possible for a sound looping node may get ResetChildren called twice.
	- Condition is when a child random node o fa looping node has a blank entry and results in no sound chosen in a given frame (which results in ResetChildren getting called). Later in the frame, if a sound had previously been playing with an active sound, it will have stop called on it, which will call NotifyWaveInstanceFinished and hit the ensure. Simply using the branch to check if the looping node has been initialized will work fine in this and other cases.

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

Change 2875025 on 2016/02/20 by Andrew.Rodham

	Sequencer: Cinematic viewport improvements
	  - Added optional letterbox overlay (defaults to 2.35:1)
	  - Added ability to change safe frame colors
	  - Added selected tracks' keys to the transport range
	  - Added buttons for jumping between selected tracks' keyframes on the transport controls
	  - Removed black padding around the viewport where possible
	  - Added ability to specify whether a combo button/menu anchor should close when its parent receives focus
	  - Separated logic of FGroupedKeyArea into FSequencerKeyCollection, so it can be used independently
	  - Added playback range to the viewport frame numbers
	  - All frame numbers are now spin boxes

	#jira UE-26429

Change 2875026 on 2016/02/20 by Thomas.Sarkanen

	Added console commands for recording sequences

	Changed plugin to a developer plugin so we can load it when the editor is in -game mode.
	Added Exec commands.
	Added some more logging to help diagnose problems when using commands.
	Added loading/saving of config for recorder settings (stored in Editor.ini).
	Also disabled controls in recorder window when recording.
	Added auto-saving of assets when in non-editor modes.
	Moved animation settings from UnrealEd to Engine module.

Change 2875036 on 2016/02/20 by Max.Chen

	Sequencer: Call RedrawAllViewports instead of RedrawLevelEditingViewports. In particular, this fixes some update issues when editing values in the key editors.

	#jira UE-26960

Change 2875046 on 2016/02/20 by Max.Preussner

	Sequencer: Fix so that clicking on UMG Animations doesn't dirty the scene.

	#jira UE-26249

Change 2875047 on 2016/02/20 by Max.Chen

	Sequencer: Add option to toggle display of channel colors/lines. View->Channel Colors

Change 2877138 on 2016/02/23 by Max.Chen

	Sequencer: Select corresponding track node when selecting key or section. Removed active/inactive selection since it was only being used in deletion and the rules for deletion are now dependent upon what is selected - delete keys and sections before deleting outliner nodes.

Change 2877143 on 2016/02/23 by Thomas.Sarkanen

	Added new math function: WindRelativeAnglesDegrees

	Given two angles in degrees, 'wind' the angle in Angle1 so that it avoids >180 degree flips.
	Good for winding rotations previously expressed as quaternions into a euler-angle representation.

Change 2877147 on 2016/02/23 by Thomas.Sarkanen

	Added the ability to import sequencer transforms from the root node of an animation sequence

	Intended for use after re-importing animations from DCC tools.
	Available in the right-click menu for transform tracks.
	Also added FindTrackBinding to UMovieScene so track bindings can be recovered from tracks.

Change 2877163 on 2016/02/23 by Max.Chen

	Sequencer: Add option to create keyframe sections as infinite. Sequencer defaults to true, UMG defaults to false.

Change 2877165 on 2016/02/23 by Max.Preussner

	Sequencer: Drawing vertical position lines when dragging keys

Change 2878748 on 2016/02/23 by Max.Chen

	Curve Editor: Switch curve type to user when flatting or straightening tangents.

	#jira UE-27277

Change 2878799 on 2016/02/23 by Frank.Fella

	Sequencer - Add folders support to the outliner.

Change 2880769 on 2016/02/24 by Andrew.Rodham

	Sequencer: Added ability to override runtime spawnable ownership in sequencer
	  - This is exposed as an option on spawnables "Keep Alive Outside Playback Range (In Sequencer)"
	  - Enabling this will stop spawnables from being destroyed when scrubbing outside of the playback range

	#jira UE-27205

Change 2880770 on 2016/02/24 by Thomas.Sarkanen

	Sequencer: Added countdown and recording indicator display when recording

	Also fixed extra popups added post-PIE when animation recordings auto shutdown.

Change 2880782 on 2016/02/24 by Max.Chen

	Sequencer: Snapping now also uses the current time as a possible snap time.

	#jira UE-26306

Change 2880793 on 2016/02/24 by Max.Chen

	Sequencer: Add +Animation to Animation track so that it's consistent with all other tracks that have a + button.

Change 2880812 on 2016/02/24 by Max.Chen

	Sequencer: Fix adjusting the leading edge of a shot section so that it cuts into the shot rather than adjusts the start time.

	#jira UE-26306

Change 2881624 on 2016/02/25 by Andrew.Rodham

	Changing shader version GUID to fix corrupt shaders in ddc

Change 2882408 on 2016/02/25 by Thomas.Sarkanen

	Asset/actors stored in TLazyObjectPtrs can now reference game content from engine

	This is a legitimate use case as lazy object ptrs are designed to reference assets/actors cross-domain.

	#test:PC

Change 2880344 on 2016/02/24 by Daniel.Wright

	Added the ability to apply DFAO to static indirect lighting, controlled by r.AOApplyToStaticIndirect
	* Lightmaps, stationary skylight and reflection captures are all affected
	* Specular occlusion on reflection captures requires a fair amount of tweaking of r.SkySpecularOcclusionStrength, MinOcclusion and MaxOcclusionDistance for good quality
	* For now, a movable skylight with low intensity (.0001) must be placed to control MaxOcclusionDistance and MinOcclusion

Change 2880346 on 2016/02/24 by Daniel.Wright

	Added several cvars to expose mesh distance field limits, which allows higher quality
	* r.DistanceFields.MaxPerMeshResolution
	* r.DistanceFields.DefaultVoxelDensity
	* r.DistanceFields.AtlasSizeXY
	* r.DistanceFields.AtlasSizeZ

Change 2881304 on 2016/02/25 by Gil.Gribb

fec728074d Custom HMD post process mesh implementation.
Instead of rendering a full screen quad for post process passes, render a mesh which represents only the screen area visible in the HMD after distortion.
This cuts the cost of post processing ~10-15% with no visible difference.
Initial implementation for the Vive.
