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

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

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

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

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

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

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

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

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

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

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

	* Planar reflections are now supported in splitscreen

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

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

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

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

	[Copy] Distance field cvar comments

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

	[Copy] Disabled selection color on Volume materials

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

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

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

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

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

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

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

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

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

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

	Missed a file.

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

	Updated items from original shelved version by Mark Satt:

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

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

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

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

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

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

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

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

	Fixed linux build hopefully

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

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

	And another fix for Windows compilation of MetalShaderFormat.

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

	Remove temp working directories after archive packages built.

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

	DR - Copy 3371640 (fix mem leak)

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

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

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

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

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

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

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

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

	LPV Fade support
	- mostly integrated from CL 2959511

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

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

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

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

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

	DR - Fix static analysis

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

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

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

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

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

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

	Fixes scene captures ordering's backward compatibility.

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

	Filter out excluded HMD modules during FEngineLoop:PreInitHMDDevice. The final selection still happens in UEngine::InitializeHMDDevice as all HMD plugins have not been loaded during PreInit

Change 3235308 on 2016/12/14 by Ryan.Vance

	#jira UEVR-478

	Monoscopic far field improvements

	Shader changes are now gated behind the read only cvar vr.MonoscopicFarField. Changing this requires a shader compile.
	Moved the mono rendering mode to the cvar vr.MonoscopicFarFieldMode. This is writable, so users can enable/disable mono rendering on the fly if the above cvar is enabled.
	Only write to the alpha channel in the mobile base pass if the object is opaque and MONOSCOPIC_FAR_FIELD is defined.
	Addressed code review comments.

	#jira UEVR-412: Rename and merge remaining Morpheus console commands
	#jira UEVR-417: Remove Exec from IHeadMountedDisplay

Change 3269971 on 2017/01/24 by Jeff.Fisher

	UEVR-498 move controller is missing world to meters
	UEVR-522 PS4 motion controller worldscale support.
	-Passing world to meters scale into getControllerOrientationAndPosition because the thing asking about it ought to be part of a world, and know what it should be.  This also avoids making PS4 motion controllers dependent on the HMD.  Note Google VR Controller doesn't do position, so doesnt' care about scale.  Oculus already had internal threadsafe tracking of world scale, so I left that.  Steam handles world scale below our input level.
	-Also adding PlayerIndex member to FSceneView so we can figure out which view the MotionControllerComponent should get its worldscale from for the late render thread update.
	#jira UEVR-498
	#review-3384107

Change 3288308 on 2017/02/06 by Jeff.Fisher

	UEVR-517 Detect MotionController Connectivity
	-PS4 can only track 2 controllers and 1 hmd.  Support for dealing with that is needed.
	-Also need to support multiple motion controller components mapped to a single controller.  Licencees have done that before.
	-Created a new interface IMotionTrackingSystemManagement, and implements it for PS4Tracker on PS4.
	-Created a MotionTrackedDeviceFunctionLibrary to expose that interface to blueprint.
	-With those one can enable and disable tracking on ps4 controllers and query their state to stay within the controller tracking limit.
	-PS4Tracker also keeps a blackboard of the enable/disable state so that one can enable or disable controllers that have not been connected yet, and have them enable tracking or not when they are connected.
	-DS4 controller no longer jumps back to 000 if it loses tracking.
	#review-3384107
	#jira UEVR-517

Change 3288309 on 2017/02/06 by Keli.Hlodversson

	Add file missing from CL#3257373.

Change 3288311 on 2017/02/06 by Jeff.Fisher

	UEVR-517 Detect MotionController Connectivity - Test content.
	-tm-motionControllers has a third mode where all playstation motion controllers for player 0 are availalbe.  You can toggle them to track or not with ctrl-P,G,L,R for pad, gun, leftmove, rightmove or with alt-P,G,L,R.  Ctrl tests doing so via MotionControllerComponent.  Alt tests doing so by player index and controller type enum.
	-ctrl-A disables tracking of all controllers
	-alt-A disables tracking of all controllers for player 0
	-ctrl-D toggles enabling new controllers by default
	-Also fixed one button not working in one of the other test modes for the Aim (gun) controller.
	-The controller 'models' have an arrow out the front.  It is black if disabled.  Red if enabled, but no tracker is active, yellow if tracked but inertial only, and green if fully tracked by the camera.
	-This logic is in the QA_MoCoAll blueprint.

Change 3291601 on 2017/02/07 by Jeff.Fisher

	UEVR-536 PSVR motion controller tracking problem with multiple controllers
	-Previous code called GetRelativeTransform from the render thread, but the game thread could update it at any time.  This caches that transform so that it can be safely used in the render thread.
	#jira UEVR-536
	#review-3384107 @Ryan.Vance

Change 3292460 on 2017/02/08 by Jeff.Fisher

Change 3313467 on 2017/02/20 by Ryan.Vance

	#jira UE-41604

	3278583
	pCustomPresent->AllocateRenderTargetTexture may return false, if we blindly return true we can end up with an invalid render target since the fall back sceneviewport will be skipped.

	* Pre VS2015 compilers don't like mixing wide and unmarked strings in concatenation. Unfortunately LOCTEXT hides the call to the TEXT macro, completely hinding the prefix (which only gets added to the first fragment.)
	* Switch apparently doesn't know how to format a size_t for analytics either.
	Also: Typo in backwards compatibility command name alias

Change 3337347 on 2017/03/08 by Jeff.Fisher

	-This does the basics of driving output through the Aux port in the proper format for display on the mirror monitor.
	-Only supports 30fps on the mirror monitor.  60fps will require the implementation of sony system dialogs to deal with incompatable system features (video streaming, remote play).
	-There is a project setting in Morpheus, under experiemental bEnableSocialScreenSeparateMode.  This must be set to true to use this feature.  When it is false we avoid allocating the back buffers.
	-MorpheusFunctionLibrary blueprints now have a node "SetSocialScreenMode" which can switch between SystemMirror (hardware supported mirroring), SeparateTest (alternates black and white), SeparateTexture (displays a texture, eg a render target, specified via blueprint), and SeparateMirror(puts the hmd render buffer on screen - which is both eyes, like a debug mode).
	-Also finally updated the bEnabled flag in project settings to tell people it's only for PC.

	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

Change 3333693 on 2017/03/06 by Daniel.Wright

	[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

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 3333843 on 2017/03/06 by Daniel.Wright

	[Copy] Added OcclusionExponent to skylight component
	* Useful for brightening up indoors without losing contact shadows as MinOcclusion does

	* Clearing the entire light attenuation buffer costs .1ms on PS4.  This optimization lowers the minimum cost of a shadow casting light from .15ms -> .03ms.
	* Shadowed lights in Fortnite with 25 lights 3.7ms -> 1.42ms on PS4

Change 3333860 on 2017/03/06 by Daniel.Wright

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

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.

	* Forward lighting of local lights can be forced with 'r.VolumetricFog.InjectShadowedLightsSeparately 0'
	* Shadowed lights come at a cost: 2.9ms for volumetric fog on 970 -> 4.2ms with shadowing

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

Change 3148067 on 2016/10/01 by Daniel.Wright

	Support for ReflectionEnvironment and light type show flags with ForwardShading

	Material expressions; Trig, fast-trig, saturate, round, truncate, pre-skinned normal.
	Added CustomEyeTangent to material attributes.
	Resolved some hard-coded attribute typing and other minor fixes.

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

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

	#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 - 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.

	Dynamic Indirect Shadows for static meshes using distance fields
	* These Distance Field indirect shadows use the same tile culled and downsampled framework that capsule shadows use, with similar GPU cost
	* Individual StaticMesh assets can enable bGenerateMeshDistanceField to compute a distance field, without the memory cost of enabling for the whole project
	* 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.

	- socket not readable or writable is not an error condition if output buffer is full
	- messages were previously limited to 64kb but screenshots overflowed this

Change 3143808 on 2016/09/28 by Steve.Cano

	Assume that the app starts in focus at startup and don't wait for an "APP_EVENT_STATE_WINDOW_GAINED_FOCUS" event to fire, as this event will not come down from SplashActivity since it is not a NativeActivity. If the user then rotates the device in Sensor or FullSensor orientation during SplashActivity and forces an eglSurface recreation, the initial Create will properly execute if we're "in focus". Previously, the create-destroy-create cycle would not properly execute due to the EventManager thinking the app was not yet in focus, and would cause the second create to get a 0x3003 error (EGL_BAD_ALLOC)

Change 3094167 on 2016/08/18 by Jeff.Fisher

	UEVR-97 Morpheus HMD tracking needs to wait until HMD is fully tracked.
	-Morpheus CALIBRATING/NOT_TRACKED tracking state hmd orientation update disabled and delegates added to present instructions to the user.  This behavior is controlled by morpheus ini setting bDisableHMDOrientationUntilHMDHasBeenTracked, but defaulted to true to avoid subtly bad user experiences.
	#review-3094106 @chad.taylor
	#jira UEVR-97

Change 3104799 on 2016/08/29 by Jeff.Fisher

	UEVR-178 Morpheus HMD Black crescents
	-Switched reprojection frame time for 60/120 mode from 120hz to 60hz so we much better predict where the hmd will be pointing when the frame we are about to render is actually displayed, and are run off the edge of it less often and less severely.  This makes the black crescent artifacts only just visible during very fast head turning.  The kWrapModeMirror change, which will be submitted separately, makes the left and right crescents invisible to me.
	-Renamed the functions for setting the prediction info in the PS4Tracker.
	-Added render frame parameters to sony reprojection functions, these can help with debugging reprojection.
	-Added commented out sce call to get the reprojection debug data.  Not allowed to submit an executable that calls it, but its nice to at least know where one can put it.  May improve this later.
	-Wrapped PS4Tracker->Synchronize call in a check that the tracker handle is valid, because I managed to get it called when it wasn't (probably during hmd power off testing, but I don't remember now).  It should be fine to not do it if the tracker is not functioning.

	Morpheus Config Improvements.
	-UEVR-138 Morpheus HMD reprojection wrap mode config setting
	-Can now switch between wrap mode Mirror and ClampToBorder.  Mirror is the default.
	-Made bDisableHMDOrientationUntilHMDHasBeenTracked editable in UE4Editor project settings.
	-Using generic project setting for bStartInVR, removed the morpheus specific one.

Change 3111231 on 2016/09/01 by Jeff.Fisher

	Fixed bStartInVR ini setting.
	-Initial implementation worked via a generic EnableStereo call, which worked, but happened after the hmd setup dialog, which is not what I wanted.
	-Also fixed a tracking frame mismatch assert that hit when I powered the hmd off once, causing it to lose tracking.  Its ok that it doesn't update in that circumstance.

	PSVR: stereo layers implementation

Change 3116593 on 2016/09/07 by Jeff.Fisher

	UEVR-126 Morpheus HMD connect dialog cancel reactions
	-VR only apps can't allow the player to cancel out of the hmd setup dialog, so lets just pop the dialog up again (sony were ok with a licencee doing this) if an ini setting says to do that.
	-VR/2D apps might want to switch to 2d if the player cancels out of the hmd setup dialog, so there is an ini setting for that.
	-A delegate only implementation is also provided for apps that want to do something else.  This leaves the game rendering in VR mode, and fires the delegate.
	-Refactored to better separate successful HMD acquisition from stereo rendering.  This was necessary to support the delegate only option on startup.  If you start in vr mode with your hmd off and cancel the dialog stereo rendering now starts with default values for the hmd hardware stats (as read from my pvt) instead of crashing trying to use uninitialized data.  When an hmd is connected its values will be read.
	-Refactored to ensure reprojection starts immediately when we call StartReprojection.

	UEVR-225 Morpheus HMD top and bottom black crescents

Change 3136652 on 2016/09/22 by Keli.Hlodversson

	Allow shutting down Steam VR subsystem without shutting down the Steam VR plugin completely in response to quitting from the SteamVR overlay. Enabling stereo rendering again will reinitialize SteamVR. This is useful when using PIE in VR mode as it allows entereing it again without restarting the editor. Also fixes crashes by first disabinge stereo rendering a short while before shutting down the VR subsystem.

	UEVR-242 Is AddControllerYawInput not allowed when morpheus is enabled?

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

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

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

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

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

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

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

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

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

	Tested/profiled on PC, PS4

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

	Fixed stationary skylight brightness

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

	Fixed r.ReflectionEnvironmentLightmapMixing

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

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

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

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

	#code.review Marcus.Wassmer

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

	View.AtmosphericFogSunColor
	View.AtmosphericFogSunDirection

	Nodes are called:
	AtmosphericLightVector
	AtmosphericLightColor

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

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

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

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

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

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

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

	Skip RF_ArchetypeObject for reflection captures

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

	Noise material perf improvements

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

	Merging //UE4/Dev-Main@3085468 to Dev-Rendering (//UE4/Dev-Rendering)

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 3011102 on 2016/06/13 by Steve.Cano

	After taking a screenshot using glReadPixels, transfer the data to the target buffer from bottom row up to fix the "upside-down" render that OpenGL does. Confirmed with QA (owen.stupka_volt) that this does not appear to be happening on iOS (non-metal devices, inclusion of iOS in write-up was a mistake), verified on an ipod touch 5. Also confirmed that this does not happen on html5, and that Mobile HDR flag does not make a difference in function.

Change 3029220 on 2016/06/27 by Steve.Cano

	Change Android Tilt values to use GetRotationMatrix/GetOrientation logic, same as java-side android would use, and adjust slightly to match as closely as possible to iOS values for tilt. There is drift and some differences in the "Y" value but the same sort of inconsistencies are also seen on iOS.

	- No channel limitations for dynamic point lights

	Notes:
	Removed mobile-specific directional light shadowing fields from View uniform buffer and mobile no longers uses SimpleDirectionalLight.
	Separate uniform buffers for mobile directional light are generated for each lighting channel.
	CSM culling information is now stored in FViewInfo and not per FVisibleLightViewInfo as the visibility bits are per view.

	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

Change 3013736 on 2016/06/14 by Daniel.Wright

	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)

Change 3019691 on 2016/06/20 by Ben.Woodhouse

	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).
