	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

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

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

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

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

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

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

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

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

	#jira FORT-31590

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

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

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

	Add missing parenthesis to fix compile error on iOS.

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

	Submitting TM-AutoLOD level to QAGame

	#jira UE-29618

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

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

	DR - vk - Fix validation spam

Change 3164679 on 2016/10/17 by Arne.Schober

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

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

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

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

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

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

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

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

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

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

	#jira UE-35878

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

	Shadow stencil optimisation with cvar (enabled by default)

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

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

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

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

	Zero bad tangents from input mesh.

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

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

	DR - [UE-34481] - Fix UT build and mac

Change 3126953 on 2016/09/15 by Rolando.Caloca

	DR - Enable GPU capture when running OpenGL under RenderDoc
	- Will also set the memory mode to non coherent so not to kill performance on RenderDoc

Change 3126966 on 2016/09/15 by Rolando.Caloca

	DR - Allow cooking for Vulkan SM4 to help with packaging

Change 3127082 on 2016/09/15 by Guillaume.Abadie

	#jira UE-35367, UE-33602, UE-33603, UE-33604
	#review-3125887 @brian.karis

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

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

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

	DR - vk - Debug dump

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

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

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

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

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

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

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

	Also fixes some potential precision issues with unit GPU timing

Change 3128247 on 2016/09/16 by Rolando.Caloca

	DR - vk - Cache framebuffers

Change 3128593 on 2016/09/16 by Rolando.Caloca

	DR - vk - Fix for crash loading map
	#jira UE-36072

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

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

Change 3130236 on 2016/09/19 by Chris.Bunner

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

Change 3130388 on 2016/09/19 by Rolando.Caloca

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

Change 3130393 on 2016/09/19 by Marc.Olano

	Improve vector noise tooltips & documentation

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

	Fix for ensure fail when initializing point light shadowmaps.

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

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

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

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

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

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

Change 3130767 on 2016/09/19 by Uriel.Doyon

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

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

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

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

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

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

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

Change 3131153 on 2016/09/19 by Rolando.Caloca

	DR - Fix recompute normals when triangles have a LHS tangent basis

	Integrate from 3028634
	- Also make meshes that don't have morphs be able to run through the recompute normals path
	#jira UE-35472

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

	Duplicate CL #3114668: Always disable asynchronous shader compilation for the global shader map on Metal as some of them are needed very early.
	#jira UE-35240

Change 3131246 on 2016/09/19 by Rolando.Caloca

	DR - Shrink gpu skinning permutations

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

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

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

	Fix FMetalDynamicRHI::RHIReadSurfaceData for shared textures on iOS.

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

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

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

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

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

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

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

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

Change 3131402 on 2016/09/19 by Rolando.Caloca

	DR - Disambiguate callstack
	#jira UE-34415

Change 3131469 on 2016/09/19 by Rolando.Caloca

	DR - vk - Check if we can allocate descriptors off a pool

	DR - vk - Remove unused var

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

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

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

	DR - vk - Compile fix

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

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

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

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

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

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

Change 3131955 on 2016/09/20 by Gil.Gribb

	Merging //UE4/Dev-Main@3129758 to Dev-Rendering (//UE4/Dev-Rendering)

	Add some additional checks to help track down a rare crash with terrain rendering and shader recompiling

	#jira UE-35937

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

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

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

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

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

	Fix mac compile error

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

Change 3137265 on 2016/09/22 by Mark.Satterthwaite

	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.

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

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

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

The order of initialisation is different per-platform:

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

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

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

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

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

	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

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

	DR - Custom Renderer callback after getting SceneColor

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

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

	#jira UE-34838

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

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

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

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

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

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

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

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

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

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

	- Re-enable non-checkerboard skin by default

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

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

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

	#jira UE-34561

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

	Removed unused reflection shape variables

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

Change 3099730 on 2016/08/24 by Daniel.Wright

	MSAA depth resolve uses depth of closest surface, hides some artifacts with dynamic shadowing against the skybox

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

	FloatRGB  is now always supported.

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

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

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