	Added CustomEyeTangent to material attributes.
	Resolved some hard-coded attribute typing and other minor fixes.

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

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

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

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

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

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

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

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

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

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

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

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

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

	DR - vk - Fix some format issues

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

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

	Changes from UE4-DX12:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

	#jira UE-35878

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

	Shadow stencil optimisation with cvar (enabled by default)

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

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

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

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

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

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 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

	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 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.

	Change Apple RHI initialisation to select the first compatible shader platform to decide which RHI to initialise. Internally in MetalRHI we must gracefully fallback to a lower feature-level when this initial selection is not available on the current device/OS, in which case we need to validate that the selected shader platform was actually packaged. The order of initialisation is different per-platform:
	On Mac: Order of initialisation is the order listed in TargetedRHIs .ini specifications.
	On iOS/tvOS: Order is explicit: Metal MRT > Metal ES 3.1 > OpenGL ES 2

	DR - [UE-33438] - Added a Project Setting to enable Skincache Shader Permuations. The Default value for the Skincache mode was changed to enabled. 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.

Change 3142762 on 2016/09/27 by Uriel.Doyon

	Added per static mesh and per skeletal mesh UV density data. The data is now saved and available in cooked builds.
	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.

	LightmapUVDensity is now computed separately from UVChannel Density.

Change 3143822 on 2016/09/28 by Arne.Schober

	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 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

	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.

	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.

	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 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()

	Sceneproxy can be nullptr in FDynamicMeshEmitterData::Init if the proxy is being recreated

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

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

Change 3028958 on 2016/06/27 by Ben.Woodhouse

	Fix for perf issue with GetSingleFinalDataConst

	This was caused by the LPV integration/switch to blendables. Now we cache the flag for the directionalocclusion in the LPV class. This reduces calls to GetSingleFinalDataConst on the blendable data (potentially slow), and makes things a bit cleaner and consistent.

	Tested in QAGame editor (with LPV enabled in ConsoleSettings.ini)

	#jira UE-26179

Change 3029401 on 2016/06/27 by Rolando.Caloca

	DR - More vk logging

Change 3029549 on 2016/06/27 by Uriel.Doyon

	Refactored "r.OnlyStreamInTextures" into "r.Streaming.FullyLoadUsedTextures", making it fully load every used textures, as an alternative to disabling texture streaming.
	New options "r.Streaming.UsePerTextureBias" that assign a  bias between 0 and MipBias to each texture in order to fit in budget.
	Fixed crash when disabling texture streaming.
	Fixed issue when disabling texture streaming that would make current loaded texture low res.
	New logic to prevent retrying to cancel a streaming request more than once.
	Pending load request of one extra mip will not be cancelled anymore.
	Changed UTexture2D from float to double. Also using FApp::GetCurrentTime() instead of FPlatformTime::Seconds().
	#jira UE-32197
	#jira UE-31102

Change 3029837 on 2016/06/27 by David.Hill

	#jira UE-31238

Change 3030607 on 2016/06/28 by Marc.Olano

	Random Number generators: fixed bug in TEA, added integer and float Blum-Blum-Shub. BBS is way cheaper for similar quality, suggest it for future use.

Change 3030627 on 2016/06/28 by Ben.Woodhouse

	Fix for warning. CVar naming scope clash (doesn't appear to happen in vs2015).

Change 3030809 on 2016/06/28 by Marc.Olano

	Noise shader function rename & perf improvement.

	Due to incorrect terminology in internet soruces, previous "Perlin" noise was not, in fact, Perlin noise. Now more accurately called "Value" noise. 6x perf improvement for value noise by changing random number function to BBS. Also updated instruction counts in UI tooltips.

Change 3030850 on 2016/06/28 by Marc.Olano

	Rename & redirect noise material enums. At some point these got switched around and no longer accurately described the noise options the selected. Redirect, so all existing content will continue to work as-is. Updated UDN docs to match.

Change 3030981 on 2016/06/28 by Rolando.Caloca

	Removing Data Objects

Change 3036942 on 2016/07/04 by Ben.Woodhouse

	Fix for decal rendering resource leak

	The cause was that FD3D11BoundRenderTargets doesn't support setting RTs sparsely. So if one element is NULL, it won't release the ones after it.

	The sparse RT layout happened as a result of a change back in October, which meant that GBuffers for decals could be set sparsely, dependent on whether the decal wrote to the normalbuffer

	This change adds support for sparsely bound rendertargets in FD3D11BoundRenderTargets.

Change 3039454 on 2016/07/06 by Simon.Tovey

	Moved all Niagara files from Engine and UnrealEd to remove dependancies and increase compile times.
	Niagara is now 99.999% decoupled from engine and editor so development should be much streamlined.

	Plus a few other edits to remove Curves/DataObjects that I missed in last CL.

	Skylight occlusion tint now applies to specular
	Skylight occlusion tint on diffuse is now correctly affected by DiffuseColor

Change 3039960 on 2016/07/06 by Daniel.Wright

	Forward renderer initial implementation
	* Point and spot lights are culled to a frustum space grid, base pass loops over culled lights.
	* Light culling uses a reverse linked list to avoid a per-cell limit, and the linked list is compacted to an array before the base pass.
	* New cvars to control light culling: r.Forward.MaxCulledLightsPerCell, r.Forward.LightGridSizeZ, r.Forward.LightGridPixelSize
	* A full Z Prepass is forced with forward shading.  This allows deferred rendering before the base pass of shadow projection methods that only rely on depth.
	* Dynamic shadows are packed based on the assigned stationary light ShadowMapChannel, since stationary lights are already restricted to 4 overlapping.
	* GBuffer render targets are still allocated
	* Fixed several issues in parallax corrected base pass reflections - not blending out box shape, discontinuity in reflection vector, not blending with stationary skylight properly
	* Forward shading is now used for TLM_SurfacePerPixelLighting translucency in the deferred path
	* Notable missing features: shadowing of translucency, support for various translucency lighting modes, multiple blended reflection captures

Change 3006514 on 2016/06/08 by Zabir.Hoque

	MIGRATING FIX @ Request

	Off by 1 error on reflection roughness calculation affecting 4.12. When I hoisted the max mip index i did a -1 on both sides(c++ & hlsl). This is the simplest hotfix. In 4.13 I'll remove the shader instruction and only do the "-1" in c++ this 1 less shader instruction.

Change 3009028 on 2016/06/10 by Daniel.Wright

	Shadow depth refactor
	* Shadow setup and render target allocation now happens in InitViews, and shadow depth rendering happens at one spot in the frame
	* This provides control over where shadow depths are rendered for things like async compute, and allows easy atlasing of shadowmaps for forward shading
	* The 33Mb of shadow depth buffers in FSceneRenderTargets has been removed, and shadow depth buffers are now allocated as needed
	* A large amount of duplicated code to handle each shadow type has been combined
	* Cleaner parallel rendering: no more view hacking for the shadow depth pass, no more shadow depths in the middle of translucency
	* 'vis ShadowDepthAtlas' or 'vis WholeSceneShadowMap' must now be used to visualize the shadow depth textures

	Cached shadowmaps for whole scene point and spot light shadows
	* Controlled by 'r.Shadow.CacheWholeSceneShadows', defaults to enabled (7ms -> 1.5ms of shadow depths on Titan for ~20 lights)
	* Primitives with Static or Stationary mobility have their depths cached, as long as the light is not moving
	* Primitives with Movable mobility or using World Position Offset in their materials will not have their depths cached
	* Cached shadowmaps are copied each frame and then movable primitive depths composited
	* Fast paths exist for when there were no static primitives (skip cached shadowmap) or movable primitives (project directly from cached shadowmap)
	* 'r.Shadow.CacheWPOPrimitives' controls whether materials using WPO can be cached (default is off for correctness)
	* 'r.Shadow.CachedShadowsCastFromMovablePrimitives' can be used to force off all support for movable primitives, skipping the shadowmap copies (1.5ms -> 0ms of shadow depths for ~20 lights)

	Add a per-object shadow setting for directional lights (r.Shadow.PerObjectDirectionalDepthBias), which is independent of the CSM setting. Often a smaller bias is desirable on per-object shadows, where detailed self-shadowing is needed.

	This change also makes the CSM naming consistent with what the setting actually does (the old setting was named r.shadow.csm, although it affects per-object shadows as well as CSMs).

	- Disabled async streaming for the duration of the QOS ping measurement to avoid hitches
	- Added a circular throbber in the top left corner of the login screen indicating that something is async streaming (as a diagnostic tool for users affected by the datacenter ping, can be removed in the future)
	- Added logging of the current average frame time when the datacenter ping is finalized
	- Added a 'Pick Ideal Settings' button to the login screen (note: on the actual screen, not the login widget, so it will not appear on PS4)

	#rb martin.mittring

Change 2803240 on 2015/12/15 by Gil.Gribb

	UE4 - Added command to collect stats on spammy stats.

Change 2803476 on 2015/12/15 by Rolando.Caloca

	DR - Allow toggling compute skin dispatch at runtime
	- r.SkinCacheShaders Now enable the shaders and feature
	- r.SkinCaching enables toggling at runtime
	- r.SkinCache.BufferSize Sets the size in bytes of buffer for outputting
	- Now uses 3 UAV buffers instead of one (avoid RenderDoc crashes)
	#codereview Marcus.Wassmer, Martin.Mittring

Change 2803940 on 2015/12/15 by Marcus.Wassmer

	Add r.PS4.AsyncComputeBudgetMode to switch between CUMasking and WaveLimit modes.  So far it looks like WaveLimits behave better in UE4.

	Also rearrange AsyncSSAO to run immediately after HZB to overlap with occlusion queries.  In my testing this takes SSAO cost from .5ms -> .2ms.   However it had to be hacked to run without normals.  Hopefully Martin can get some real AsyncSSAO in.

	#rb Martin.Mittring
	#codereview Martin.Mittring

Change 2803999 on 2015/12/15 by Uriel.Doyon

	Refactored the shader complexity material override logic to allow other viewmodes shader overrides.
	TexelFactorAccuracy ViewMode : shows the accuracy of the static mesh texel factors, used for streaming.
	WantedMipsAccuracy ViewMode : shows the accuracy of the static mesh wanted mips accuracy, used for streaming.
	Added an option to stream textures based on the AABB distance instead of using the sphere approximation.
	Added an option to only keep a the wanted mips.
	Moved optimization related viewmodes into a submenu to avoid polluting the interface.

Change 2804150 on 2015/12/15 by Olaf.Piesche

	make separate translucency screen percentage a bit more robust; add numsamples to the render target creation functions in preparation for MSAA support for higher quality with low res separate translucency

	#rb martin.mittring

Change 2804367 on 2015/12/15 by Daniel.Wright

	Capsule shadow primitives are tracked separately on registration - saves 2.6ms of RT time doing the view frustum culling in a medium sized map

Change 2805293 on 2015/12/16 by Olaf.Piesche

	logging if potentially immortal emitters are spawned from gameplay; this should catch if we spawn burst only emitters with indefinite life spans (muzzle flashes, hit impacts, etc.)

	#rb martin.mittring

Change 2805586 on 2015/12/16 by Zabir.Hoque

	Adding support for decals to fade and destroy themselves automatically.

	#CodeReview: Martin.Mittring, Daniel.Wright, Olaf.Piesche

	#test:editor

Change 2811205 on 2015/12/22 by Brian.Karis

	Pulled clear coat out of the reflection compute shader. Added permutation for skylight.

	Clear coat base layer now done in base pass. It only picks up the closest capture. This will cause popping when the object moves. Still needs a cross fade.

Change 2811275 on 2015/12/22 by David.Hill

	UE-24675

	Fixed SCW always exiting after compiling a long shader, now checks idle time starting from the end of the last compile task
	Automated smoke tests aren't run in standalone programs which are frequently launched as they increase the startup time (doubles startup time of SCW as shown in sampling profile)
	#rb Rolando.Caloca

Change 2772471 on 2015/11/18 by Daniel.Wright

	Particle SubUV cutouts
	* A new asset type 'SubUV Animation' precomputes bounding geometry for every frame of a SubUV texture animation.
	* Particle emitters with a SubUV module can then use this SubUV Animation to render with much tigher bounding geometry to reduce overdraw.
	* GPU performance savings depend on how much empty space (zero alpha) existed in the texture.  Measured a reduction of 2-3x GPU time on a smoke effect.
	* This only works if the material does not modify opacity to reveal areas with zero texture alpha
