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 3121996 on 2016/09/12 by Ben.Marsh

	Add support for Visual Studio 2017 (aka "15"; assuming consistent naming with other versions until final name is announced).

	* Compiler, STL implementation and CRT are binary compatible with VS2015 (see https://blogs.msdn.microsoft.com/vcblog/2016/08/24/c1417-features-and-stl-fixes-in-vs-15-preview-4/), so no new third-party libraries needed so far. WindowsPlatform.GetVisualStudioCompilerVersionName() returns "2015" as a result.
	* Default compiler for compiling and generating project files is still VS 2015 for now. Pass -2017 on the command line to GenerateProjectFiles.bat to generate VS2017 projects. Projects generated for VS2017 will use the 2017 compiler by default.
	* Visual Studio source code accessor can talk to VS 2017 instances.
	* Added a VS2017 configuration for UnrealVS, and added precompiled vsix package.
	* Switched GetVSComnTools to check the SOFTWARE\Microsoft\VisualStudio\SxS\VS7 registry key rather than the individual product install registry key. "15" doesn't seem to have it's own "InstallDir" key, but this system seems to work for all versions of Visual Studio (including previous releases of VS Express).
	* Removed ATL dependency from VisualStudioSourceCodeAccessor. It's not installed with VS by default any more, and is only used for a couple of smart pointer classes.

	Tested running the editor and packaging TP_Flying for Win64. Packaging from the editor still defaults to using the 2015 compiler, so ConfigureToolchain() needs to be overriden from the .target.cs file if multiple Visual Studio versions are installed.

Change 3189363 on 2016/11/07 by Ben.Marsh

	Consolidate functionality for determining the path to MSBuild.exe to use for compiling UE4 tools into a single batch file (GetMSBuildToolPath) and fix "Clean" not working on PS4 due to include/library paths being set to something by the Visual Studio environment.

Change 3210598 on 2016/11/27 by Ben.Marsh

	UBT: Prevent the name of each file compiled being output twice on XboxOne. Compiler already outputs this string; the action doesn't need to.

Change 3210601 on 2016/11/27 by Ben.Marsh

	PR #2967: Add silent version of switch game version (Contributed by EricLeeFriedman)

Change 3210602 on 2016/11/27 by Ben.Marsh

	PR #2964: GitDependencies shouldn't try to clean up working directory files that are excluded or ignored (Contributed by joelmcginnis)

Change 3210605 on 2016/11/27 by Ben.Marsh

	UGS: Add a warning when syncing latest would remove changes that have been authored locally. Typically happens when working with precompiled binaries.

Change 3211656 on 2016/11/28 by Ben.Marsh

	UBT: Move ModuleRules and TargetRules into their own file.

Change 3211797 on 2016/11/28 by Ben.Marsh

	UBT: Remove utility functions from TargetRules for checking different classes of target types. Moving TargetRules to be data-only.

Change 3211833 on 2016/11/28 by Ben.Marsh

	UBT: Remove overridable configuration name from target rules. This feature is not used anywhere.

Change 3211859 on 2016/11/28 by Ben.Marsh

	UBT: Deprecate the GetGeneratedCodeVersion() callback in favor of a member variable instead.

Change 3211942 on 2016/11/28 by Ben.Marsh

	UBT: Remove legacy code which tries to change the output paths for console binaries. Output paths for monolithic binaries are always in the project folder now.

Change 3215333 on 2016/11/30 by Ben.Marsh

	UBT: Replace the GetSupportedPlatforms() callback on TargetRules with a SupportedPlatforms attribute. Since a TargetRules object can only be instantiated with an actual platform, it doesn't make sense for it to be an instance method.

Change 3215482 on 2016/11/30 by Ben.Marsh

	UBT: Remove the GetSupportedConfigurations() callback on the TargetRules class. A configuration is required to construct a TargetRules instance, so it doesn't make sense to need to call an instance method to find out which configurations are supported.

Change 3215743 on 2016/11/30 by Ben.Marsh

	UBT: Deprecate the TargetRules.ShouldCompileMonolithic() function: this function requires access to the global command line to operate correctly, which prevents creating target-specific instances, and does not use the platform/configuration passed into the TargetRules constructor.

	Rather than being a callback, the LinkType field can now be set to TargetLinkType.Modular or TargetLinkType.Monolithic from the constructor as appropriate. The default value (TargetLinkType.Default) results in the default link type for the target type being used. Parsing of the command-line overrides is now done when building the TargetDescriptor.

Change 3215778 on 2016/11/30 by Ben.Marsh

	UBT: Mark overrides of the TargetRules.GetModulesToPrecompile method as obsolete.

Change 3217681 on 2016/12/01 by Ben.Marsh

	UAT: Prevent UE4Build deleting .modules files when running with the -Clean argument; these files are artifacts generated by UBT itself, not by the exported XGE script.

Change 3217723 on 2016/12/01 by Ben.Marsh

	UBT: Run pre- and post-build steps for all plugins that are being built, not just those that are enabled.

Change 3217930 on 2016/12/01 by Ben.Marsh

	UGS: Add a perforce settings window, allowing users to set optional values for tuning Perforce performance on unreliable connections.

Change 3218762 on 2016/12/02 by Ben.Marsh

	Enable warnings whenever an undefined macro is used in a constant expression inside an #if or #elif directive, and fix existing violations.

Change 3219161 on 2016/12/02 by Ben.Marsh

	Core: Use the directory containing the current module to derive the UE4 base directory, rather than the executable directory. Allows UE4 to be hosted by a process in a different directory.

Change 3219197 on 2016/12/02 by Ben.Marsh

	Core: When loading a DLL from disk, convert any relative paths to absolute before calling LoadLibrary. The OS resolves these paths relative to the directory containing the process executable -- not the working directory -- so paths need to be absolute to allow UE4 to be hosted by a process elsewhere.

Change 3219209 on 2016/12/02 by Ben.Marsh

	Replace some calls to LoadLibrary() with FPlatformProcess::GetDllHandle(). The UE4 function makes sure that relative paths are resolved relative to the correct base directory, which is important when the host executable is not in Engine/Binaries/Win64.

Change 3219610 on 2016/12/02 by Ben.Marsh

	Add the -q (quiet) option to the Mac unzip command, since it's creating too much log output to be useful.

Change 3219731 on 2016/12/02 by Ben.Marsh

	UBT: Add option to disable IWYU checks regarding the use of monolithic headers (Engine.h, UnrealEd.h, etc...) and including the matching header for a cpp file first. bEnforceIWYU can be set to false in UEBuildConfiguration or on a per-module basis in the module rules.

Change 3220796 on 2016/12/04 by Ben.Marsh

	Remove PrepForUATPackageOrDeploy from the UEBuildDeploy base class. It never has to be accessed through the base class anyway.

Change 3220825 on 2016/12/04 by Ben.Marsh

	UBT: Change all executors to derive from a common base class (ActionExecutor).

Change 3220834 on 2016/12/04 by Ben.Marsh

	UBT: Remove the global CommandLineContains() function.

Change 3222706 on 2016/12/05 by Ben.Marsh

	Merging CL 3221949 from //UE4/Release-4.14: Fixes to code analysis template causing problems with stock install of VS2017.

Change 3222712 on 2016/12/05 by Ben.Marsh

	Merging CL 3222021 from //UE4/Release-4.14: Change detection of MSBuild.exe path to match GetMSBuildPath.bat

Change 3223628 on 2016/12/06 by Ben.Marsh

	Merging CL 3223369 from 4.14 branch: Use the same logic as GetMsBuildPath.bat inside FDesktopPlatformBase to determine path to MSBuild.exe

Change 3223817 on 2016/12/06 by Ben.Marsh

	Remove non-ANSI characters from source files. Compiler/P4 support is patchy for this, and we want to avoid failing prey to different codepages resulting in different interpretations of the source text.

Change 3224046 on 2016/12/06 by Ben.Marsh

	Remove the need for the iOS/TVOS deployment instances to have an IOSPlatformContext instance. The only dependency between the two -- a call to GetRequiredCapabilities() -- is now implemented by querying the INI file for the supported architectures when neeeded.

Change 3224792 on 2016/12/07 by Ben.Marsh

	UBT: Touch PCH wrapper files whenever the file they include is newer rather than writing the timestamp for the included file into it as a comment. Allows use of ccache and similar tools.

Change 3225212 on 2016/12/07 by Ben.Marsh

	UBT: Move settings required for deployment into the UEBuildDeployTarget class, allowing them to be serialized to and from a file the intermediate directory without having to construct a phony UEBuildTarget to deploy.

	Deployment is now performed by a method on UEBuildPlatform, rather than having to create a UEBuildPlatformContext and using that to create a UEBuildDeploy object.

	The -prepfordeploy UBT invocation from UAT, previously done by the per-platform PostBuildTarget() callback when building with XGE, is replaced by running UBT with a path to the serialized UEBuildDeployTarget object, and can be done in a platform agnostic manner.

Change 3226310 on 2016/12/07 by Ben.Marsh

	PR #3015: Fixes wrong VSC++ flags being passed for .c files (Contributed by badlogic)

Change 3228273 on 2016/12/08 by Ben.Marsh

	Update copyright notices for QAGame.

Change 3229166 on 2016/12/09 by Ben.Marsh

	UBT: Rewritten config file parser. No longer requires hard-coded list of sections to be parsed, but parses them on demand. Measured 2x faster read speeds (largely due to eliminating construction of temporary string objects when parsing each line, to trim whitespace and so on). Also includes an attribute-driven parser, which allows reading named config values for marked up fields in an object.

Change 3230601 on 2016/12/12 by Ben.Marsh

	Swarm: Change Swarm AgentInterface to target .NET framework 4.5, to remove dependency on having 4.0 framework installed.

Change 3230737 on 2016/12/12 by Ben.Marsh

	UAT: Stop UE4Build deriving from CommandUtils. Confusing pattern, and causes problems trying to access instance variables that are only set for build commands.

Change 3230751 on 2016/12/12 by Ben.Marsh

	UAT: Move ParseParam*() functions which use the instanced parameter list from CommandUtils to BuildCommand, since that's the only thing that it's instanced for.

Change 3230804 on 2016/12/12 by Ben.Marsh

	UBT: Add the IsPromotedBuild flag to Build.version, and only set the bFormalBuild flag in UBT if it's set. This allows UGS users to avoid having to compile separate RC files for each output binary.

Change 3230831 on 2016/12/12 by Ben.Marsh

	UGS: Warn when trying to switch streams if files are checked out.

Change 3231281 on 2016/12/12 by Chad.Garyet

	Fixing a bug where .modules files were getting put into receipts with their absolute path instead of their relative one

Change 3231496 on 2016/12/12 by Ben.Marsh

	Disable code analysis in CrashReportProcess; causes warnings when compiled with VS2015.

Change 3231979 on 2016/12/12 by Ben.Marsh

	UBT: Suppress LNK4221 when generating import libraries. This can happen often when generating import libraries separately to linking.

Change 3232619 on 2016/12/13 by Ben.Marsh

	Fix "#pragma once in main file" errors on Mac, which are occurring in //UE4/Main.

	#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.

	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

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

Change 3072947 on 2016/08/01 by Uriel.Doyon

	Texture GUIDs are now included in cooked builds, as they are required by the texture streamer to link build data to in game texture.
	#review-3072934 @marcus.wassmer
	#jira UE-34045

Change 3073301 on 2016/08/02 by Ben.Woodhouse

	Fix for large spotlight culling precision issues, reported on UDN by Aaron Jacobs at Double Fine. For a full description, see the UDN post
	https://udn.unrealengine.com/questions/305440/shadowed-light-flicker-caused-by-floating-point-pr.html
	#jira UE-34052

Change 3073689 on 2016/08/02 by Ben.Woodhouse

	Improved skin postprocess - support for full resolution, with diffuse/spec lighting combined into single RGBA (sharing chroma)

	Full res lighting gives less temporal AA flickering, sharper diffuse and specular lighting in the surface (since this is now at full resolution), faster postprocessing if using a 64-bit rendertarget (on NV 980Ti).

	Checkerboard rendering is controlled via the r.sss.checkerboard cvar. - 0 is off/full res, 1 is checkerboard, 2 is automatic based on scenecolor (non-checkerboard requires 64bit or more rendertarget w/separate alpha)

	Tested/profiled on PC, PS4

Change 3074666 on 2016/08/02 by Daniel.Wright

	Fixed stationary skylight brightness

Change 3074667 on 2016/08/02 by Daniel.Wright

	Fixed r.ReflectionEnvironmentLightmapMixing

Change 3074687 on 2016/08/02 by Daniel.Wright

	Disallowed DrawMaterialToRenderTarget and Begin/EndDrawCanvasToRenderTarget in construction scripts, since they don't work in game.  Blutilities can be used to do blueprint rendering in the editor.

Change 3075241 on 2016/08/03 by Rolando.Caloca

	DR - Fix linux compile issue & static analysis warning

Change 3075746 on 2016/08/03 by Daniel.Wright

	Removed bOverride_AntiAliasingMethod and outdated ini references to PP AntiAliasingMethod

Change 3075783 on 2016/08/03 by Ryan.Brucks

	#code.review Marcus.Wassmer

	Added two material nodes that return Atmospheric Light Vector and Light Direction using:

	View.AtmosphericFogSunColor
	View.AtmosphericFogSunDirection

	Nodes are called:
	AtmosphericLightVector
	AtmosphericLightColor

	Also changed SceneRendering.cpp so that values will be grabbed from directional lights without needing an Atmospheric Fog actor in the scene.

Change 3075969 on 2016/08/03 by Uriel.Doyon

	Material GUIDs are not updated anymore when parents or textures change.
	Lighting now uses a hash built from the list of parents, textures and shader functions.
	#review-3072980 @marcus.wassmer @daniel.wright

Change 3076116 on 2016/08/03 by Ryan.Brucks

	#review-3072984 @marcus.wassmer

Change 3077616 on 2016/08/04 by Daniel.Wright

	Planar reflection show flags can now be edited

Change 3077621 on 2016/08/04 by Daniel.Wright

	Changed default Planar Reflection DistanceFromPlaneFadeoutEnd from 600 to 100, which reduces artifacts and is a more intuitive initial setting

Change 3077792 on 2016/08/04 by Daniel.Wright

	Fixed an unnecessary sky capture caused by the sky light component owned by the default ASkyLight

Change 3077799 on 2016/08/04 by Daniel.Wright

	Skip RF_ArchetypeObject for reflection captures

Change 3077876 on 2016/08/04 by Marc.Olano

	Noise material perf improvements

	Change random number generator for Gradient-ALU (1.7x perf boost), improve speed of Voronoi noise quality level 3.

	Removes integer BBS random number generators. Fewer instructions, but too slow to use (see 1.7x perf boost above)

Change 3077884 on 2016/08/04 by Daniel.Wright

	Lighting channels can now be edited on components with static mobility, since dynamic lights can still affect them

Change 3078994 on 2016/08/05 by Simon.Tovey

	Fix for UE-34241
	Scene proxy ptr was being cached during a downcast.
	Inside a call to CreateDynamicData, CheckMaterialUsage_Concurrent() was causing the scene proxy to be recreated an so the cached ptr was stale.
	I've fixed the immediate issue but recreating the scene proxy here doesn't seem great. Maybe CheckMaterailUsage() should be rethought a bit.

Change 3079162 on 2016/08/05 by Ben.Woodhouse

	Fix for jittering in Paper2D. Was caused by override being ignored due to a change in intiialization order for AA settings.
	#jira UE-34091

Change 3079613 on 2016/08/05 by Daniel.Wright

	New blueprint function ClearRenderTarget2D, which is the only way to set a render target alpha directly
	New blueprint function CreateRenderTarget2D

Change 3079708 on 2016/08/05 by Uriel.Doyon

	Fixed crash when building texture streaming on some levels.

Change 3079795 on 2016/08/05 by Uriel.Doyon

	Fixed issue with instanced static meshes when building texture streaming.
	Fixed typo with func "GetNumTextureStreamingPrimitives"

Change 3079806 on 2016/08/05 by Uriel.Doyon

	Enabled PerTexture MipBias. The per texture mip bias now resets to 0 when the texture gets required at low resolution.
	New scalability setting named "r.Streaming.LimitPoolSizeToVRAM" enabling the PoolSize to be limited the available VRAM
	(according to GPoolSizeVRAMPercentage)
	#review-3074662 @marcus.wassmer

Change 3082698 on 2016/08/09 by Daniel.Wright

Change 3084645 on 2016/08/10 by Olaf.Piesche

	#jira UE-30398

	Fix offset added to particle collision locations.

Change 3084709 on 2016/08/10 by Daniel.Wright

	Copy - Scene capture alpha is now inverted to match DrawMaterialToRenderTarget, and to allow compositing with existing render target contents
	Added CompositeMode to SceneCapture2D, which can be used to addively accumulate or composite instead of the default overwrite behavior
	Added bCaptureOnMovement to SceneCapture, which can be disabled so the only source of scene capturing is a manual capture by calling CaptureScene()

Change 3084783 on 2016/08/10 by Rolando.Caloca

	DR - Use the first targeted rhi shader platform as the initial RHI to load on Windows
	#jira UE-34510

Change 3084958 on 2016/08/10 by Daniel.Wright

	Copy - Reverted cl 2938543 "Lightmass now respects owner bHidden, and bCastHiddenShadow" because it did not have backwards compatibility so breaks content using hidden light cards

Change 3086023 on 2016/08/11 by Marcus.Wassmer

	Merging //UE4/Dev-Main@3085468 to Dev-Rendering (//UE4/Dev-Rendering)
	#test none

Change 3089208 on 2016/08/15 by Daniel.Wright

	Downsampled separate translucency uses a separate view uniform buffer with correct buffer sizes
	* Fixes WorldPosition in downsampled translucency
	* View uniform buffer parameters are now cached on the view, to allow recreating the uniform buffer without having to rebuild the entire struct.  Currently used by global distance field, downsampled separate translucency.
	* Fixed the downsampled translucency depth buffer being full res used together with a smaller color target, now they are both the downsampled res

Change 3089209 on 2016/08/15 by Daniel.Wright

	Fixed atmospheric fog on translucency

Change 3089457 on 2016/08/15 by Daniel.Wright

	Fixed lighting build failure from UMaterialInstanceDynamic assigned to a mesh that's being exported to Lightmass.  The Swarm cache entry is created using the parent's guid, causing multiple MID's with the same parent to acquire a file handle multiple times which fails after the first.

Change 3089549 on 2016/08/15 by Daniel.Wright

	UMaterialInterface initializes LightingGuid to something valid - causes UMaterialInstanceDynamic to have a valid LightingGuid so they can be used in lighting builds

Change 3089703 on 2016/08/15 by Daniel.Wright

	Custom expression fixup for View.RenderTargetSize

Change 2975196 on 2016/05/12 by Robert.Manuszewski

	Garbage Collector will no longer be responsible for generating class token stream, instead the token stream will be generated on startup or when a class has finished loading.
