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

	[Copy] Fixed volumetric fog being offset when viewport min is not 0

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 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.

	DR - [UE-32613] - OpenGL used to have custom code in the compiler to modify the source so that the same data and matricies can be used as DirectX, unfortunately that causes precission problem. Fortunately there is an extension available (glClipControl) which enables DirectX behaviour in OpenGL and it is widely supported. We only tested Linux and Windows and therfore only default enable on those platforms.

	Move the Metal shader source code and compilation path into the newly enlarged shader optional data.

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

	#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 - vk - Fix validation spam

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.

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)

	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.

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

	#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.

	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.

	- 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.

	Duplicate CL #3135169:
	Correct Metal texture creation for AVF media framework - we can't provide a render-targetable version of the texture without blitting. The native texture we get is a GPU copy that can be made CPU accessible (i.e. it is not tiled).

Change 3137266 on 2016/09/22 by Mark.Satterthwaite

	Duplicate CL #3135237:
	Metal validation layer fix: under Metal if there are no reads from the vertex stage-in buffers we should use the Empty vertex declaration, not the filter declaration, otherwise we have to bind a redundant vertex stream buffer to silence the validation layer.

	Fix GPU selection code in MetalRHI to confirm everything is working.
	#jira FORT-30385

Change 3137269 on 2016/09/22 by Mark.Satterthwaite

	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 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

	Improved UV density computation and viewmode.

	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

	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.

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

	DR - vk - fixes for depth/stencil descriptors

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

	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

Change 3088355 on 2016/08/13 by Max.Preussner

	Media Player Editor: Fixed Local file paths without file:// open when pressing Enter, but not when clicking Go button (UE-34643)

	Porting DX12 Fix from MS:

	Update D3D12 RHI for 4.13
	 - Fixed compiler errors with missing RHI methods. Fixed compiler warnings where names were hidding other variables.

	#jira UE-0

Change 3088149 on 2016/08/12 by Mark.Satterthwaite

	Duplicate CL #3087991:
	Initial AVFoundation implementation of Media Framework for Mac, iOS & tvOS.
	- Slight adaptation of AppleMovieStreamer to pick up movies from inside the GameContentDir on all Apple platforms.
	- Video playback occurs via AVPlayerItemVideoOutput's attached to the AVPlayerItem's output. This means gathering video samples is trivial.
	- Metal texture updates occur by wrapping the texture object provided by AVF - for Mac this is simple as it can bind to the IOSurface directly, for iOS/tvOS we have to create a CVMetalTextureCache and allocate our texture from there.
	- OpenGL and OpenGLES currently have to lock the pixel buffer and upload to a texture the old fashioned way - this should be revisited when there is time.
	- Subtitles/Captions are captured using AVPlayerItemLegibleOutput which also connects to the AVPlayerItem's output.
	- On Mac audio samples are returned by manually reading from the stream using an AVAssetReaderTrackOutput, including manual seeking and synching.
	- On iOS/tvOS the audio is played directly by AVPlayer because the IOSAudio system can't handle procedural buffers - otherwise it could reuse the Mac code.
	- AVFoundation does not support AVI - that's an obsolete Microsoft/Windows file-format.
	- Only 'file://' URLs are supported - streaming would require a totally different audio solution (using MTAudioProcessingTap) and has many more edge and failure cases that would need to be handled.
	#jira UE-34315

	#jira UE-34564

Change 3088099 on 2016/08/12 by Zabir.Hoque

	Move end of frame resource clean up to end of viewport rendering, since EndFrame calls were not consistently coming in when movie was playing but asset loading was done.

	UEVR-13 PSVR: TCR Requirements : sceHmdReprojectionSetOutputMinColor
	Exposed sceHmdReprojectionSetOutputMinColor to blueprint via Morpheus Function Library.
	Allows one to set the minimum output color from reprojection processing.  Can be used to mitigate certain artifacts (dark smearing, reprojection edges).  See Sony documentation for more information. This setting does persist across switches out of vr mode and hmd disconnection, but it has no effect out of vr modes.

Change 3087200 on 2016/08/12 by Robert.Manuszewski

	Fix for potential deadlock when a worker thread crashes caused by critical section lock in FOutputDeviceRedirector. The engine will no longer attempt to flush log messages in CheckRenderingThreadHealth if a critical error has already occured. Crash handlers flush log anyway.

	#jira UE-34373

Change 3087188 on 2016/08/12 by Matthew.Griffin

	Added SignExecutables Option to installed build script, which defaults to false and means most people won't have to pass -nosign anymore

Change 3087148 on 2016/08/12 by Ben.Marsh

	Fix sample build failure due to intermediate headers being deleted from engine folder. Some modules only have *private* UObject classes which aren't included in the editor zip. UBT detects that there are no longer and UObject classes and deletes the intermediate folder, causing BuildGraph to fail when it detects the change.

Change 3087143 on 2016/08/12 by Danny.Bouimad

	#jira UE-29618 updated QA-AnimProfiles and SK_Mannequin_PhysAssetTest to include constaint profiles for switching, removed old map in wrong folder.

	GitHub 2256 : Update UnrealCodeAnalyzer.Build.cs

	I have no evidence that this actually fixes anything, but it doesn't harm anything to add it...

	#jira UE-29286

Change 3087139 on 2016/08/12 by Steve.Robb

	Failed link actions during a hot reload now output a 'failed.hotreload' file in the destination folder to indicate that another link attempt is needed.
	This is because we can't distinguish between a successful compile with a failed link action, and a compile with no changes which requires no new module.

	#jira UE-31575

Change 3087107 on 2016/08/12 by Jurre.deBaare

	Alembic Import with empty first frame will cause the editor to crash

Change 3085799 on 2016/08/11 by Ben.Marsh

	Pass the -ignorejunk option to UBT when generating code documentation. Since the UE_SDKS_ROOT environment variable is removed (because we don't want documentation for confidential platforms), UBT was deleting Linux target platform DLLs and causing an error when generating blueprint documentation when the files were missing.

	Duplicated from Dev-Editor, CL 3084475

	Fix to MathExpression node - recent modifications caused subte changes in behavior (now back in line with how it worked before). Identifiers (variable names) are back to allowing numerical characters, and we properly detect the terminating 0 at the end of a name/string. Also, reserving symbols that currently aren't operators (as they used to be) so users don't start including them in identifier names.

	#jira UE-34458

Change 3084027 on 2016/08/10 by Ben.Woodhouse

	Fix for crash when applying BSP materials
	This was caused by the renderthread dereferencing a reference to a ModelElement object which had previously been destroyed on the game thread.

	The reference to the ModelElement was solely used to dereference the irrelevant light GUIDs. The fix involves removing the reference and keeping a local copy of this array which is owned by the proxy. This is consistent with other proxies, e.g. Landscape, StaticMesh.

	PR #2516: CMake improvements and fixes (UE-22233, UE-32136).

	- Contributed by Nihlus.
	- Contains PR #1668 by mgerhardy

	Summary of changes (from PR):

	- Fixed an issue where CMake build files would contain invalid targets
	- Fixed an issue where CMake build files would generate without code completion data, making them useless in IDEs such as CLion.
	- Fixed an issue where invalid target platforms could fall through and cause issues with the file generation.
	- Improved code readability throughout the generator. Can still use some more polish.
	- Improved CMakeFile generation performance by approximately 25%. Before this patch, generating a CMakeFiles.txt for a small-ish project took 20s - by replacing most string concatenation with StringBuilders, it now takes approximately 15s. This should be more apparent in larger projects.
	- Improved commenting throughout the generator. As with readability, can still use some more polish.
	- Removed unused using statements.
	- Added the inclusion of a fake executable target to the CMake files. Some IDEs do not recognize header files that are not part of either an executable or a library. While this target will not build, it is neccesary in CLion.
	- Replaced all instances of String.Format with string interpolation expressions from C#6. This greatly improves readability, and helped me catch some bugs with the build targets.

	Xbox One - Fix a controller disconnection crash.

	- This would only reproduce in VS2015 Update 3, and only when the controller is connected right from the start, not when a pad is plugged in later, so it seems copying the array of ^ pointers wasn't incrementing the refcounts correctly and causing things to be deleted too early.
	- Changed it to copy each connected pad object one at a time, which maintains the correct refcount.

	#jira UE-34325 Implementing 3080958 in 4.13

	- When a sound buffer is flushed from audio device manager and tries to stop sounds using a resource, was possible for the async header parse task to be in-flight, which would cause a crash
	- Fix is to bring back the code to call EnsureCompletion on tasks in the FreeResoruces function of the sound source object. This will potentially encure a slight perf increase when stopping a sound but audio engine is now going to run on a separate thread, so shouldn't have a game-thread impact in non-editor builds.

	Duplicate CL #3064008 & CL #3077412:
	Fix "iOS Metal-based build crashes at launch with sub-levels":
	- Slate should not bind the null RHI texture from an unitialised texture atlas - atlases only have a valid texture pointer once an entry has been added to them and in the template projects an empty sub-level doesn't add anything.
	- To prevent this kind of bug resurfacing and being so hard to track down add Metal shader binding validation to our validation layer as Apple's is incomplete on iOS and won't warn us about nil texture usage which causes these GPU restarts. This requires reworking our vertex declaration handling to be more efficient so that we can cache the pipeline reflection data as well as the pipeline objects.
	- Fix validation error of texture reallocation on loading template projects under Metal.

	Sequencer: Fixed sequencer adding spawnables into recorded worlds twice

	The issue here is that sequencer was re-evaluating itself with the current play world as the context, which also happened to be the world that it was trying to record. As a result, it ended up with the same sequence being played twice in the recording world.

	Added the ability to specify a playback context attribute for sequencer to use, and this no longer allows sequencer to play back in any worlds that are being recorded.

Also making a tweak to WidgetCache, to update the lasthittestindex to be the one passed in, which is a bit closer to the intended behavior.

Change 3073788 on 2016/08/02 by Andrew.Rodham

	Sequencer: Added support for montage based animation

	CL#3061714 :
	    Sequencer: Fixed anim trails not playing in full, sequencer-driven animation.

	    There were 2 issues here. Firstly, we were force-handling events and anim notifies in non-preview animation which caused undefined behaviour when the animation was also updated on tick. Secondly, On the very first frame of a game, sequencer can sometimes use the PreviewSetMatineeAnimPositionInner method because the actor it is referencing has not begun play yet. Unfortunately this function left the animation in a state where the 'real' animation update function wouldn't trigger any anim notifies properly.

	CL#3063015 :
	    Sequencer: Fixed anim notifies not working when playing animation on blueprint-driven skeletal meshes

	    We now inject a new animation position into the animation system, rather than trying to 'fake' events outside of the system. This allows for much more robust event triggering when playing back through sequencer. Previously, anim notifies for trail particles would be reset every frame due to TriggerAnimNotifies being called by the animation system, and sequencer. We now defer this responsibility to the animation system entirely during playback.

	CL#3068399 :
	    Sequencer: Changed animation tracks to allow more animation types (such as anim montages)

	      - APIs now accept UAnimSequenceBases rather than UAnimSequences to afford more flexibility

Change 3073542 on 2016/08/02 by Richard.TalbotWatkin

	Duplicated from Dev-Editor, CL 3072169.

	A couple of changes to the BSP code:
	* Fixed longstanding issue where sometimes BSP geometry is not rebuilt correctly after editing it.  This was due to poly normals not being recalculated after translating vertices in Geometry Mode.
	* Fixed corruption to FPoly::iLink as it is overloaded to have two meanings: when building BSP, it temporarily represents the surface index of the next coplanar surface (and adding a new BSP node uses this to determine whether a new surface needs to be added or not). In other operations it represents an FPoly index, in general this is used more in editor geometry operations.  This fixes various crashes which arose from rebuilding BSP resulting in invalid FPoly indices.

	#jira UE-12157 - BSP brushes break when non-standard subtractive bsp brushes are used
	#jira UE-32087 - Crash occurs when creating Static Mesh from Trigger Volume

	Duplicated from Dev-Editor, CL 3057895

	Mesh paint bugfixes and improvements.

	Changes to RerunConstructionScript so that OnObjectsReplaced is called correctly on all components, whether they have been created by the SCS or the UCS. Previously, components created by the UCS were not being handled, and components created by the SCS were not always being matched.  Now a serialized index is maintained for UCS-created objects, which is matched after the construction scripts have been executed.

	This will fix issues with the mesh paint tool, and any other editor tool which hooks into the OnObjectsReplaced callback in order to update its internal cache of component pointers, for example, the component visualizer render list.

	Manually integrated some fixes from Dev-Blueprints

Change 3073311 on 2016/08/02 by Richard.TalbotWatkin

	Duplicated from Dev-Editor CL 3057868

	Spline component improvements, both tools and runtime:

	- SplineComponentVisualizer now works within the Blueprint editor. This works via a generic extension added to the base ComponentVisualizer class which correctly propagates modified properties from the preview actor to the archetype, and then on to any instances whose properties are at the default value.
	- The above feature required a breaking change to USplineComponent - namely, the three FInterpCurve properties have been collected together into a struct and added as a single property. This is so that changes to the length of one of the FInterpCurves marks all three as dirty and needing rebuilding.
	- Added a custom version for SplineComponent and provded serialization fixes.
	- Added a details customization to SplineComponent to hide the raw FInterpCurve properties.
	- Added a custom detail builder category which polls the SplineComponentVisualizer each tick and provides numerical editing for spline points which are selected in the visualizer.
	- Relaxed the limitation that SplineComponent keys need to have an increment of 1.0.  Now any SplineComponent key can be set.  The details customization enforces that the sequence remains strictly ascending.
	- Allowed an explicit loop point to be specified for closed splines.
	- Allowed discontinuous splines by no longer forcing the ArriveTangent and LeaveTangent to be equal.
	- Added some new Blueprintable methods for building splines with an FSplinePoint struct, which allows all of a spline point's properties to be specified, and added to the FInterpCurves sorted by the input key.
	- Fixed the logic which determines whether the UCS has modified the spline curves.
	- Added UActorComponent::RemoveUCSModifiedProperties, which allows a component to remove any properties from the cached list which it doesn't want to be considered as 'modified'. This is used to distinguish the case of properties preserved by the SplineInstanceDataCache from those genuinely modified by the UCS.
	- Fixed "Apply Instance Changes to Blueprint" so that edited spline data can be applied to the archetype.
	- Fixed some issues with the spline component visualizer to make it generate appropriate up vectors if scale and rotation are enabled.

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

Change 3055495 on 2016/07/19 by Marc.Olano

	Allow Noise material node on mobile

	No reason to exclude mobile, except for Fast Gradient Noise, which uses 3D textures. Allow this node on ES2 for all of the other noise functions.

	#jira UE-33345

Change 3055602 on 2016/07/19 by Luke.Thatcher

	Fix crash bug in D3D11 RHI when selecting adapters.
	 - Array of adapter descriptors will get out of sync with the adapter index if any adapter is skipped (e.g. the Microsoft Basic Render Device).
	#jira UE-33236

Change 3055890 on 2016/07/19 by Daniel.Wright

	More info to 'Incompatible surface format' GNM assert

Change 3055904 on 2016/07/19 by Daniel.Wright

	Reflection environment normalization improvements
	* Indirect specular from reflection captures is now mixed with indirect diffuse from lightmaps based on roughness, such that a mirror surface will have no mixing.  Reflection captures now match other reflection methods like SSR and planar reflections much more closely.
	* When a stationary skylight is present, Reflection captures are now normalized as if the initial skylight will always be present, giving consistent results with static skylight reflections.  The skylight and reflection captures with sky removed used to be normalized separately, compacting the relative brightness between the sky and scene.
	* Added r.ReflectionEnvironmentLightmapMixing for debugging lightmap mixing issues.  This toggle was previously not possible due to prenormalizing the capture data.
	* The standard deferred reflection path (r.DoTiledReflections 0) can no longer match the results of the compute path or base pass reflections, as it would require MRT to accumulate the average brightness
	* Removed unused r.DiffuseFromCaptures
	* Cost of reflection environment on PS4 increased from 1.52ms -> 1.75ms with this change, but decreased back to 1.58ms by reducing tile size to 8x8

Change 3055905 on 2016/07/19 by Daniel.Wright

	* Deferred passes like shadow projection, fogging and decals are only computed per-pixel and can introduce aliasing
	* Added Rendering project setting VertexFoggingForOpaque, which makes height fog cheaper and work properly with MSAA
	* The AntiAliasing method in PostProcessSettings has been removed, this may affect existing content
	* Added r.MSAACount which defaults to 4
	* Integrated wide custom resolve filter from Oculus renderer, controlled by r.WideCustomResolve
	* GBuffer targets are no longer allocated when using the forward renderer
	* Decal blend modes that write to the GBuffer fall back to SceneColor emissive only

	Note: this is currently disabled by default. Enable with the cvar r.gpustatsenabled
	Tested on PC, XB1, PS4

	Planar reflections
	* New actor and component
	* The scene is rendered to texture with a mirrored camera and a clip plane each frame
	* The reflection texture is then applied to opaque pixels in a deferred pass, with distance and angle from plane fades
	* Translucent materials apply the nearest reflection plane in the base pass
	* Planar reflections require the project setting 'Support global clip plane for Planar Reflections' to be enabled, since writing to SV_ClipDistance all the time adds about 15% BasePass GPU time on PS4
	* Fixed global distance field in materials which had been broken since moving global distance field properties into the view uniform buffer
	* Fixed PS4 removing system-value semantics when output from vertex shader and not read in next stage

556b5a068e Implement the SSR stencil pre-pass behind the console variable r.SSR.Stencil
This feature buidls a stencil buffer according to the rougness in the GBuffer to make the difference between pixels that need a SSR computation and those who don't, instead of an early return in the SSR shader itself. Therefore SSR pixel shader invocations will only be for pixel that needs on hardware that have a high resolution stencil test before the pixel shader invocations packing into front lines, removing the efficiency drop caused by the thread that might early return in front lines that still have at least one thread that didn't early return.
