b11ea1332c Base pass can output velocity data for moveable object with no static lighting, in forward and deferred rendering. This saves cpu draw call submission.
In base vertex and pixel shader pass, uniform variable OutputVelocityBuffer is tested to ouput or not velocity data
Configurable per project and/or per platform (r.BasePassOutputsVelocity)

	- Now not using templates to handle input parameters to data interface. Now taking a bit from the bytecode offset to denote constant vs register.
	- As well as improving compile times, this also makes DIs far easier to write and maintain so I've rolled out to all DIs. Has no affect on perf.

Change 4415679 by Rolando.Caloca

	UE4.21 - Copy fix from 4415584 and 4401641
	- Added support for -vulkanpresentmode=N where N is a VkPresentModeKHR
	- This prevents the CPU from getting more than one frame ahead of the GPU. In addition to making the Vulkan RHI more consistent with the DX RHIs and reducing game input latency, this also fixes the issue where memory for volatile uniform buffers could be overwritten by the CPU before the GPU was done with it. This could happen when running in immediate present mode with frame pacing and smoothing disabled, as the CPU could get several frames ahead of the GPU.

	Linux: switch to Vulkan by default (UE-62807).

	[Vulkan][Engine] Update the Vulkan RHI to obey r.VSync (and the vsync and novsync command-line arguments).

	Change 4222769 by Jason.Stewart[at]Jason.Stewart_AMD_Dev_Rendering_threadripper-win10 on 2018/07/19 10:55:48

		The original implementation ran into a latent thread hazard between the RHI thread and the rendering thread, where the rendering thread would try to use the backbuffer of the swap chain while the swap chain was being recreated (specifically after the swap chain recreation code had released and nulled out the back buffer, but before swap chain creation had actually happened to get a new back buffer). This implementation addresses that issue.

		This is Tim's code. I'm just submitting it as Tim is currently out of office.

Change 4331946 by Luke.Thatcher

	[CONSOLE] [^] (merging CL 4162064) Implement new thread heart beat clock to solve the suspend/resume problem across all platforms.
	 - The hang and hitch detectors now maintain their own clocks which are ticked by their respective threads.
	 - If the title is suspended, the ticking thread will stop and the clock will stop advancing. On resume, the maximum delta in the clock is clamped to a small value, so we ignore all the time the thread was not ticking for (i.e. the duration of the title being suspended).
	 - As such, we don't need any logic for handling PLM suspend/resume in the hang and hitch detectors, so this change removes that too.

	#jira FORT-96886

Change 4331973 by Luke.Thatcher

	[CONSOLE] [^] (merging CL 4183499) Add frame-present-based hang detection.
	 - RHIs call FThreadHeartBeat::PresentFrame() whenever they present a frame to the swap chain.
	 - These calls form a separate heartbeat from the thread-based ones, allowing the hang detector to fire if, for example, the game thread is stuck in an async loading loop and is ticking the game thread heartbeat, but making no progress.
	 - Also refactored ThreadHeartBeat.cpp to move hang detection logging into a FORCENOINLINE function. This will put OnHang and OnPresentHang at the top of the callstack in retail crash dumps, making the bucketing easier to recognise.

Change 4332200 by Luke.Thatcher

	[CONSOLE] [+] (merging CL 4227517) Add PlatformDebugData to FShaderResource.
	 - We can use this to store platform specific shader symbols etc. The data gets serialized to the DDC and can be retrieved during a cook.
	 - Data is entirely discarded in cooked builds, and is a no-op on platforms which don't implement support for shader debug data.
	 - Bumped shader version to invalidate DDC keys.

	[CONSOLE] [CORE] [!] (merging CL 4279686) Fixed unaligned integer load macro inconsistencies.

	#jira none

Change 4092798 by Matt.Collins

	Some HDR refactoring.

	Previously the DisplayOutput and ColorGamut were only set in GameUserSettings.
	I added a Sink that checks the HDR enable. If it's toggled we apply the correct DisplayOutput and ColorGamut for the current platform (this way we get good settings even if you toggle via the console). These settings are still exposed via the console and can be set independently if the user wants.

Change 4096954 by Chris.Bunner

	Added ShaderModelID as scene texture option and renamed existing value to ShaderModelColor to better reflect the internal code.

	Planar reflection prefilter - use scene viewport size instead of reflection target size in order to keep filter size constant in screen space. This makes planar reflection filter more stable in case of dynamic resolution.

	#jira none

Change 4167644 by Krzysztof.Narkowicz

	Global shader map is now stored in multiple DDC entries (one per shader filename) instead of keeping everything in a single one. This allows to skip recompilation of unchanged shader files.

Change 4183727 by Yuriy.ODonnell

	Implemented auto-conversion from deferred to DBuffer decals in forward shading mode (when GBuffer is not available).

	Added support for specular and metallic channels for DBuffer decals, based on work by Chris Bunner.
	This requires DBufferC to be expanded from 2 to 4 channels, leading to slight increase in DBuffer bandwidth and memory requirements.

	Appearance of DBuffer decals is affected by this change, as specular and metallic channel values previously hard-coded in DBufferDecalShared.ush.
	Decals were forced to be non-metallic and have specular of 4% (0.5 numeric value). Now the authored decal material values will be used, which matches GBuffer decals.

	Added support for DBuffer decals with emissive component.

	Most decal types can now be automatically converted, with the exception of stain decals. Those are currently approximated as regular translucent decals.

Change 4197684 by laz.matech

	Added a PostProcess Volume test to the map to test that Cinematic Depth of View can be achieved through PPVs as well. Changed the BP_DepthOfFeildPOV asset - I exposed Focus Method so that it can be disabled for the PPV test. Added a second Hair Model head to the InFocusHair test so that it tests in and out of focus hair models (changed the name of the test to FocusHair).

Change 4334607 by Uriel.Doyon

	Added custom overrides to reset ULightComponent::Intensity to default (in FLightComponentDetails).
	Now settings a light Intesity to default resets the brightness to the archetype brightness.
	This handles correctly cases where the intensity units differs between the two objects.
	Also changed FLocalLightComponentDetails so that changing intensity units kepts the same brightness
	(by recomputing the Intensity).

Change 3810363 by Mark.Satterthwaite

	More random fixes to mtlpp: most important is the extension to Buffer that allows creation of sub-buffers that are merely views onto a sub-range of the parent. These sub-buffers are valid to use throughout the mtlpp API with two exceptions: they may not be used for visibilityResultsBuffers and Set*BufferOffset functions cannot take this offset into account (as the encoder does not hold onto the buffers and I don't want it to). In the case of Set*BufferOffset the caller has to know what is going on and in the case of visibilityResultsBuffers it'll just assert as it isn't sensible.

	This makes it *much* easier to do things like sub-buffer allocation, though the caller must be aware of the alignment restrictions of their intended usage as they are not possible to enforce. For example, a call to SetVertexBuffer requires an offset alignment must match the alignment of the data-type in the shader for "device" resources, or for "constant" data it must be max(4, sizeof(datatype)) on iOS and 256 on macOS. This should allow for much more tightly packed sub-allocations than earlier approaches, though older drivers (e.g. Mac OS X 10.11) enforce only the coarser "constant" data restriction everywhere.

	rd_route v1.1.1 with attached TPS approval.

	For macOS function interposition which is useful for debugging and the occasional workaround.

Change 3845164 by Mark.Satterthwaite

	Add LLM support for macOS, including tracking of memory allocated in Objective-C. This makes use of runtime method swizzling in the Objective-C runtime and the rd_route library I added for Richard Wallis, which allows for arbitrary runtime function interposition and allows me to hook the custom allocators used in Apple's many Objective-C frameworks on which the whole macOS edifice is built. Objective-C objects are charged to the calling scope as they are too common to impose their own without murdering frame rate.

	We would need a TPS approval for an iOS function interposition library for this to work fully on iOS, if desired in the short term discarding LowLevelFree events that aren't in the map rather than asserting will workaround the problem.

	Duplicate #3831616

	Fix the black ground scattering on Metal - we've had issues with the atmospheric fog calculations for a long time - one or more intermediate operations generates different precision on Metal so we end up passing -ve values into sqrt which then generates NaN/INF. For Metal when compiling this file and this file only #define sqrt() to sqrt(abs()) so that we don't see anymore unexpected black in atmospheric rendering. This is far from ideal but I don't want to make abs all inputs into every sqrt because AFAIK this is the only case where we have an issue, and until we to investigate each intermediate calculation that isn't ridiculously, soul-crushingly tedious, it isn't practical to identify the source of the error.

	- We can't use the optimisation of loading texture width & height from the buffer meta-table in tessellation shaders as the combined stages don't guarantee not to clobber unused buffer slots and screw it up when we use linear textures.

Change 3877428 by Krzysztof.Narkowicz

	Merged with tiny tweaks Ansel photography plugin improvements from Adam Moss (GitHub pull request #4426):
	-The free-roaming photography camera has new constraints by default, i.e. it can't pass through walls
	-Photography session can be started and stopped programmatically, e.g. making it possible to bind photography to an alternative hotkey or button combo. This was an often-requested feature.
	-Tweakables and utilities are now exposed through a Blueprint Function Library (rather than direct manipulation of console variables)
	-The Ansel photography session UI now exposes some engine effect tweakables as sliders. For example, if the game is using depth-of-field then sliders are made available to allow the photographer to change the focal depth etc. The developer may suppress this behavior through the Blueprint Function Library.
	-Letterboxing is now removed during multi-part capture, d'oh.
	-Tiled shots are taken at full resolution even if ScreenPercentage < 100
	-SSR is enabled during super-resolution shots since Ansel is now better at hiding any ensuing artifacts
	-Postprocess settings are frozen at session start to avoid discontinuities during photography, i.e. wandering between postprocess volumes when the camera auto-moves for stereo and 360 shots.

Change 3891925 by Yuriy.ODonnell

	Fix/workaround for inconsistent preprocessor definitions for NVAftermath that result in FD3D11DynamicRHI class layout mismatch. NVAftermath support is now enabled by default for Win64.

	NVAftermath is declared as a private dependency in D3D11RHI. It does not automatically propagate to modules that explicitly include private RHI headers (OculusHMD, OSVR, OSVRInput). This results in NV_AFTERMATH being defined while compiling RHI module and not defined when compiling other modules, causing memory corruption at runtime.

	The long-term solution for this and similar issues requires some mechanism for adding transitive module dependencies, so that anyone that depends on D3D11RHI module would automatically also get the NVAftermath. Additionally, private headers should *never* be included directly by external modules.

	The short-term solution is to explicitly add NVAftermath dependency to OculusHMD, OSVR and OSVRInput.

	Additionally, NV_AFTERMATH is no longer forced by D3D11RHIPrivate.h when it's not defined. This allows catching this kind of mismatch in the future through a compiler warning (C4668).

	[Integrate] Scene Textures uniform buffer
	* Base Pass Uniform Buffer now contains a Scene Textures uniform buffer.  Previously the translucent base pass had to check ~40 loose scene texture parameters every draw.
	* FMeshMaterialShader's must now bind PassUniformBuffer and supply a valid pass uniform buffer.  For most passes this is just FSceneTextureUniformParameters.
	* FRendererModule::DrawTileMesh can now cleanly set dummy scene texture resources, just by configuring how the pass uniform buffer is created.
	* Moved scene texture shader functions out of Common, into SceneTexturesCommon which must be manually included by shaders that want to use them
	* Separate Mobile Scene Textures uniform buffer to silo the platform complexities

	Moved DBuffer inputs out of FDeferredPixelShaderParameters and into FOpaqueBasePassUniformParameters

	Removed per-frame material uniform expressions.  GameTime material node with period is now implemented with an fmod in the shader, without the use of MaterialFloat, so that it will happen at full precision.
	* Per-frame expressions were used when the GameTime material node had a period, to do the fmod on the CPU where 32 bit precision is guaranteed, for mobile GPU's where pixel shader precision is sometimes less than 32fp.

	Moved forward shading data into the Base Pass Uniform Buffer
	Removed instanced stereo support for the light cull grid - will have to be reimplemented without changing SRV's per draw
	Base pass sets View Uniform Buffer from DrawRenderState instead of choosing which one to set per-draw

	Moved FSceneTextureUniformParameters out of the opaque base pass uniform buffer.
	* Base Pass shaders now enable SCENE_TEXTURES_DISABLED when compiling for a material of any domain other than MD_Surface.  These are used when rendering thumbnails of a material in a different domain, which could be opaque, but the opaque base pass drawing policy does not bind a scene textures uniform buffer, so the shader must not bind it.
	* Opaque materials can no longer use EyeAdaptation.

	Clone of CL 3974146 converted for mtlpp along with extra mtlpp usage suggestions by Mark Satt:

	Fix for black flickering on first paint with weighted material landscape on Mac.  When using AsyncCopyFromBufferToTexture in Metal we put the blit operation on the prologue encoder - however after a draw call using that resource the copy operation should happen after on the current encoder, this keeps the correct order of operations.

	Initial implementation of tracing profiler to show CPU and multiple GPUs on the same timeline. Currently only supported on DX12 platforms.

	Use `TracingProfiler frames=N` console command to trigger a capture of the next N frames. Trace is saved to disk as a JSON file into `Saved/Profiling/Traces` directory.
	Trace file uses Google Tracing format and can be visualized in Chrome built-in profiler (chrome://tracing).

	`r.GPUStatsChildTimesIncluded=1` CVar makes timing scopes hierarchical.
	`TracingProfiler.BufferSize=N` CVar controls the size of the tracing buffer, which may need to be increased for long traces (default is 65k events). Only can be set at startup.

Change 3990064 by Mark.Satterthwaite

	Ensure that packed globals are reuploaded when the command-encoder is restarted - don't simply invalidate the existing parameters. This properly handles cases where a single logical render-pass is broken into multiple command-encoders and/or command-buffers - otherwise all shaders must reset all parameters each time. When we move between frames we *do* want to perform a full state reset though as previous frame globals are treated as invalid.

Change 3990080 by Mark.Satterthwaite

	Change the way we invalidate the visibility buffer between command-buffers and command-encoders so that on iOS you can reuse the same buffer within the same command-buffer, but not across more than one. The code provides an exception to this rule when running under the MetalRHI validation tools which can break each draw call into its own buffer.

	FStaticMeshComponentRecreateRenderStateContext didn't flush deferred render updates causing stale RenderData to be left:
	1. Thumbnail manager called SetStaticMesh(nullptr), which added StaticMeshComponent to deferred render updates.
	2. UStaticMesh::Build called FStaticMeshComponentRecreateRenderStateContext and destroyed DenderData, but didn't touch Thumbnail's manager StaticMeshComponent as it was nullptr.

	- Dynamic components do not need to register to the streaming manager anymore.
	- Optimized dynamic component management by removing duplicate entries in the update list.
	- Added a pregarbage collect pass to the dynamic component management to optimize GC handling.
	- Added a budget reset logic whenever the scene requirements change significantly.
	- PIE worlds now have correct visibility information.
	- Fixed possible invalid memory access when processing the streaming manager slave views.
	- Refactored the incremental level texture data build to prevent new components from being unhandled.
	- Removed StreamingManager callbacks for NotifyActorSpawned() and NotifyPrimitiveAttached()
	- Added a StreamingManager callback NotifyPrimitiveUpdated(), to be used whenever a primitive streaming state must be updated.

	No video when playing HLS streaming video on Mac.  2 Issues, FPS was zero making duration for video sample buffer nonsense and Video Track dimensions were going to zero on the AVAsset once fully initialized when playing HSL streams.  Now cache relevant details and handle zero frame rate.

	Notes:
	- Caching the frame rate is not as important as we could look it up each time and fix for zero - ignoring that at the moment.
	- Assume we DO NOT want the FrameSize to be the last fetched video frame size from the AvfMediaVideoSampler as I think that is the video quality for streaming video and not the media frame size.

	Fix broken rendering on Metal that tracked back to the innocuous looking changes in CL #4006495 (no blame attached - these changes are entirely reasonable) and cause various bugs in QAGame's TM-DistanceFields, ElementalDemo and probably more. Doesn't fix broken SpeedTree rendering :(.

	MetalRHI was allowing uniform buffers to blow away linear texture buffers when the constant buffer has been elided due to dead-code elimination. This problem can manifest without linear textures if the uniform buffer contains both constant data and a resource-table but the shader doesn't use any of the constant data. That's because Metal doesn't separate constant buffers from any other kind of buffer unlike D3D which separates all the slots out - and Metal doesn't provide enough buffers to emulate the D3D arrangement. So far this has only manifested in the MVF + Linear Texture case but a more robust solution will be necessary long term.

Change 4025337 by Yuriy.ODonnell

	Improved use-after-free detection mechanism and physical memory usage of MallocStomp on Windows.

	MallocStomp on Windows will now reserve virtual address space for every allocation and then commit physical pages only to the valid usable part.
	Physical pages will be unmapped on Free, but virtual address space will not be released and therefore will never be re-used.

	Virtual address space is allocated from the OS in blocks of 1GB and then linearly sub-allocated.
	This reduces VA space usage, as VirtualAlloc returns blocks on 64KB granularity even if we just need 4KB. As a small bonus, this also reduces number of syscalls per allocation.

	This dramatically increases accuracy of use-after-free detection, but consumes significant amount of memory for the OS page table.
	Virtual memory limit for a process on Win10 is 128 TB, which means we can afford to keep virtual memory reserved for a long time.
	Running Infiltrator demo consumes ~700MB of virtual address space per second.

	Additionally, committing physical pages only for the usable part of the entire virtual block reduces physical memory usage by ~30% compared to old behavior,
	which allocated and committed entire block of pages via BinnedAllocFromOS and then marks border page as non-accessible.

Change 4030225 by Yuriy.ODonnell

	Static analysis warning fix: make sure declaration of Sleep() is consistent between Windows headers and TBB

	The complexity with this particular case is that the warning is generated in synchapi.h, which is included by some Windows headers.
	If a module includes TBB and then Windows platform headers, static analyzer will report this warning.
	Suppressing it would require wrapping all instances of Windows header includes in third-party macros.

	Current pragmatic solution is to modify the Sleep() declaration in TBB header to be consistent with Windows and to report the issue to Intel for a permanent fix.

	Fixed UStaticMeshComponent modifying its UStaticMesh when undoing a change.  This caused a crash when other static mesh components using the same mesh asset were rendered, since their rendering state was not recreated.  A component should not modify its asset during PostEditUndo.
	 * This behavior has been present for a long time but was previously hidden because only the vertex factory of the mesh asset is cached in static draw lists, not any of its rendering resources (eg vertex declaration).

	Projects targetting OpengGL don't have access to compressed formats (as the implementation has texture tiling issues).
	Add "r.AllowVolumeTextureAssetCreation" set as 0 by default, which controls whether volume texture can be sampled in materials and whether they can be created from 2D texture assets.
	Platform not supporting BC7, will now fallback on RGBA8 instead of DXT to preserve quality, in an attemps to increase usage of BC7.

Change 3903799 by Daniel.Wright

	[Integrate] Pass Uniform Buffers
	* All pass-constant shader inputs should go into the appropriate pass uniform buffer, instead of being set per-draw
	* Moved many per-draw base pass parameters over to the Base Pass Uniform Buffer
	* Opaque and Translucent base pass shaders have different uniform buffers, which allows compile errors when accessing an invalid resource (eg GBuffer in Opaque), instead of silently falling back to GBlackTexture

	Uniform buffers can now contain nested structs with UNIFORM_MEMBER_STRUCT()
	* This allows composing a uniform buffer at a particular update frequency out of many features, with encapsulation of each feature's parameters in a struct.
	* Eg deferred fog uses FFogUniformParameters, but so does translucency in the base pass, where FFogUniformParameters is reused nested inside the base pass uniform buffer.
	* Resources can now be located anywhere in the uniform buffer.  Padding is inserted to the cbuffer representation to keep memory layouts matching.  In the future the cbuffer could be compacted.
	* RemoveUniformBuffersFromSource() which works around HLSLCC lack of struct initializers now handles nested structs

Change 3979171 by Mark.Satterthwaite

	Copying //Tasks/UE4/Dev-UERNDR-354-mtlpp to Dev-Rendering (//UE4/Dev-Rendering):

	Rewrites MetalRHI in terms of mtlpp, which is a C++ wrapper library built around Metal's Objective-C API that attempts to reduce overheads and eliminate resource lifetime errors.

	Regarding mtlpp:
	- The mtlpp library uses C++ constructor/destructor and smart-pointer style management of Objective-C retain/release calls to prevent over- and under-release problems.
	- To reduce Objective-C overheads the mtlpp library caches the internal C-function that implements the Objective-C selectors for the most commonly used Metal protocol types and calls the function directly - this avoids objc_msgSend which does this look-up dynamically and thus improves CPU performance slightly.
	- Another advantage is that mtlpp provides infrastructure to extend the Metal API slightly to help improve MetalRHI - the two important aspects are mtlpp::CommandBufferFence which provides a consistent CPU<->GPU synchronisation primitive and sub-buffer allocations from mtlpp::Buffer which allow for far superior memory management.
	- Validation functionality is also provided by mtlpp to detect CPU vs. GPU data races and resource lifetime validation - this is expensive and is thus optional and compiled out from Shipping binaries that should be used when performance is most critical. The validation only works between resource modification and *submitted* command-buffers - anything that is being actively encoded on the CPU is ignored and it remains the responsibility of the application to validate the order of operations when encoding.

	Apple Platform:
	- LLM support which tracks Objective-C objects is enabled only on macOS - we don't have the necessary libraries to intercept and override the internal system calls on iOS.

	MetalRHI:
	- All the types are switched over, (mostly) insuling the external API from the horror of Metal and Objective-C.
	- Buffers are now managed quite differently, small buffers are allocated from a magazine allocator that allocates in fixed blocks from a larger parent buffer, intermediate sized buffers are allocated from a simple heap allocator that wraps a larger buffer and anything of reasonable size (>2Mb) will use the pooled allocator. This *radically* reduces the number of buffer resources, by as much as a factor of 10, because they are now sub-allocated without the need to use MTLHeap or MTLFence so they are performance equivalent to the existing implementation on the GPU and much faster on the CPU. Total memory use is approximately the same.
	- Vertex & index buffer management has been updated to reflect changes in the management and to avoid reallocating buffers which provide a Linear Texture (for SRVs) unless strictly necessary. This ensures that even in cases where a dynamic buffer is updated multiple times in a frame it will still work acceptably well.
	- The Metal ring-buffer implementation is completely different again, this time it can use Managed memory on macOS which allows for much better performance on eGPUs which will be more and more important for Mac.
	- Everyone that needs to wait on a command-buffer fence (rather than a command-buffer itself) now use mtlpp::CommandBufferFence, which prevents race conditions between the different command-buffer handlers (which sometimes execute out of order).
	- LLM tracking should now report the same data as the MetalRHI stats group for buffer & texture allocations - there is no segmentation for Vertex/index/Structured/Uniform allocations in Metal so these numbers are going to be wrong and will need to be rethought.
	- What will be unseen are the number of small but important resource usage fixes that avoid stale resources from being bound to the device after the point at which they become invalid. This should eliminate a class of errors where the GPU uses a resource pointer that is modified by the CPU and was necessary to satisfy the new mtlpp validation code.

	Other:
	- Remove the Metal focused workarounds from the ClothBuffer resource binding and related vertex-buffer SRV - these were put in when MetalRHI/MetalShaderFormat couldn't handle float->uint conversions correctly and they should now.
	- Fix a validation error caused by trying to render a 0-sized scissor rect which is invalid in Metal and simply pointless elsewhere.
	- Consistency of disabling the Manual Vertex Fetch behaviour in shaders.

Problem stems from the extra call to update the slate cached window position in mouse move while dragging, which is itself is a hack but apparently this is needed as we don't get window position updates on Mac while dragging (although I couldn't see any -ve side effects without it) then the OS (in 10.12.6) doesn't always push out a final window did move notificaiton when changing desktops which leaves the window according to slate incorrectly positoned to it's frame.

	Solution is to either remove the mouse-move-while-drag window position hack or add a final window position update to the mouse-up event while dragging - this change is the latter.

Change 3697501 by Richard.Wallis

	Move audio processing over to audio bus tap.  Currently on Mac Media audio playback uses OS media player mixer rather than Engine as existing implemtation, using AVAssetReader, now suffers from poor performance with new Media Framework.  This audio tap version replaces that asset reader implementation but also suffers from bad quality audio hence is still disabled at the top of AvfMediaTracks.cpp.

	Original Code Review Description:

	Convert Mac to Play audio through the engine MediaFramework API rather than using AVMediaPlayer.  This is the Mac implementation only - this should work ok on iOS but unable to test due to missing audio type implementation (throws error "Init Buffer on unsupported sound type name = Synth type = 5"), as such is only enabled for Mac.  There maybe some extra tweaks required for iOS on app backgrounding etc if this feature is enabled.

	- Stuttering Audio Performace issue investiagation:  Re-Tested this implementation against [now fixed] current Mac implementation which was working fine last year and that implementation now has the same audio output quality (performance) issues as this one.  Basic investigation seems to point to somewhere in the engine audio handing.  When poor audio is heard the FMediaAudioResampler::Generate() function is dequeing an IMediaAudioSample sample buffer and the audio sample queue usually has 50-100 of these IMediaAudioSample buffers waiting in the queue.  I think the AvfMedia playback system is providing the sample buffers in good time but they are not getting consumed "fast" enough.  This under consuming also occurs if I force the Core Audio - Audio Unit mixer to use 48000 samples/sec.

Increase MAX_THREADS multiplier per bank from 22 to 26. Intel VTune ITT event annotations. Wrapped in same function as your existing CPU events and enabled with √vtune. Optimize NV cloth by consuming FVector instead of FVector4 out of the solver. Vertex buffers were using FVector all along. ~15% improvement. Optimize cloth copy to vertex buffer by adding prefetch (similar to how bones are already done). Move local to world cloth transform from CPU to GPU.

Change 3710454 by Mark.Satterthwaite

	Refactor the way we compile Buffer<> & RWBuffer<> types for Metal so that we can support the type-conversion semantics of HLSL/D3D.
	- Buffer<> types are converted to Linear Textures unless the internal type is 3-compnent or the STRONG_TYPE macro is added as a type-qualifier. Linear Textures require an MTLTexture "view" object be created around the MTLBuffer which is the backing-store and it is typically best if that buffer is marked as Private (GPU-only) memory, reading from this in the shader then uses the texture-fetch hardware to perform the format conversion on load.
	- RWBuffer<> & 3-compnent Buffer<> types are converted to use template functions to load/store - the implementation of which will read the format from the BufferSizes meta-table and determine which type-conversion to apply. Function-constants are used to specialise the shader where feasible to reduce branch costs (function-constants are a Metal feature that allow efficient runtime recompilation of bytecode shaders).
	- Buffer<> & RWBuffer<> types where the STRONG_TYPE macro is added as a type-qualifier (only does something on Metal, everywhere else it is #define'd away) are compiled as "raw" Metal buffers of the inner-type (e.g. float4 for Buffer<float4>) and the MetalRHI runtime will enforce that only SRVs/UAVs of the proper format are bound to it. This is necessary in a couple of cases (BoneMatrices, NumCulledLightsGrid, CulledLightDataGrid & ForwardLocalLightBuffer buffers) which are used in a larger number of shaders as Linear Textures have poorer performance than Buffer<>/RWBuffer<>.
	- Most of the complications to generating subtly different Metal code for different OS/device combinations have been factored out into ue4_stdlib.metal which acts as an extension to the Metal shader standard-library and helps simplify the MetalBackend code - particularly helpful for Buffer<>/RWBuffer<> but also texturecube_array and the SM6 wave-related intrinsics.
	- Reverted some of the awkward Metal-specific changes Richard.Wallis & Arne had to make to the high-level shaders as they aren't necessary anymore.
	- Made the existing Metal-specific changes to use uint32 for all light-grid injection buffers apply to all Metal platforms again (I had hoped that it would not be necessary anymore, but it is much faster this way).
	- STRONG_TYPE is actually hlslcc's "invariant" keyword applied as a type-qualifier to a Buffer<>/RWBuffer<> type - only valid when using Metal which exports this through ILanguageSpec and #define'd out for everyone else.
	- Old versions of iOS (anything earlier than iOS 10.3) won't be able to use this new code, so every buffer will be treated as "raw" and the MetalRHI will now properly report when something goes awry rather than it leading to mysterious rendering errors and crashes.

Change 3713494 by Richard.Wallis

	Fix for hitch when PIE unloading sublevel.  PerformReachabilityAnalysisOnObjects is spawing multiple threads in Editor builds as there is an extra code path that results in Critical Section locking within a singleton type static object - this is a bottle neck for multiple threads.  However they all just need to read the data not change it.  Replaced FScopeLock with a Read/Write version allowing these threads to all take a read lock at the same time to reduce contention.

	Changed the FUObjectAnnotationDense implementation only - left the sparse implementation alone as its not currently affecting this - although we could proactivly change that too.

	Load/Store{+2,3,4} & Atomics are supported. Counter operations are not supported and aren't likely to be.

Change 3713636 by Mark.Satterthwaite

	Enable LPVs for Mac Metal.
	- Rework some multi-dimensional arrays & array-index dependent HLSL code that hlslcc simply can't cope with, the mesa-glsl compiler core is only capable of dealing with 1 dimensional arrays and array-indexing can't itself be directly dependent on the result of an array-index operation.
	- MetalRHI needs to ignore any SetRenderTargets call that binds nothing at all as you must bind at least one target (UAV, RT, Depth/Stencil) for it to be able to do anything sensible.
	- Turn on LPVs for Metal as it works now.

	Lightmass correctness fixes
	* After these changes, point, spot, directional and sky lights closely match reference renderer Mitsuba after light unit conversions
	* Photon density trimming intended for direct photons was affecting indirect photons as well.  This caused high noise for point / spot lights with a large attenuation radius.  Indirect photon density even for small lights is 5x with this change, which improves 2nd bounce quality.
	* Removed legacy fudge factor on point / spot light photon energy
	* Spotlights no longer emit based on indirect photon paths.  Fixes excessive photon energy from spot lights as they were emitting outside of the cone.
	* Fixed photons computing one more bounce than requested.
	* Added an option to use the Radiosity solver for all multibounce, replacing photons.  Useful as a reference but generally too much noise indoors.
	* Fixed visualization of photons without final gather

	No more Metal Shader Model 4 - instead we have to have a Metal Shader Model 5 w/o Tessellation as Nvidia's shader compiler is broken on all tessellation shaders in 10.13.0 and above. There is no guarantee that they will fix this prior to 10.14 and I can't afford to disable tessellation entirely as if I do that then the AMD & Intel compilers will also regress. As there is no Shader Model 4 platform on Mac anymore I've amended the LevelEditorActions to disable the preview modes when no appropriate shader platform is available.

	- Material no longer have to deal with BufferUV, and post process material after TAA upsample can sample any scene buffer seamlessly;
	- Material texture per view mip bias to produce sharper images with TAA upsample;
	- Render thread dynamic resolution heuristic is fully plugable by game code (for VR plugin specific heuristics);
	- Dynamic resolution in PIE and game builds;
	- Busy time queries in the RHI to be implemented on the different platforms so that the dynamic resolution heuristic can  exactly associate GPU frame times with screen percentages in its history;
	- Game user settings to enable/disable dynamic resolution;
	- In editor viewport screen percentage config to previsualise and test content at different screen percentage.

	Fixes:
	- Various fixes for algorithms producing different outputs at different screen percentage.
	- Various fixes for algorithms sampling outside view rects.

	Refactors:
	- TAA shader
	- Moved some screen percentage specific members from FSceneView to FViewInfo for thread race bullet proofing.

	Aknowledgements:
	- VR plugins are broken
	- DFAO still have some artifacts

	Premiliminary review: Marcus.Wassmer
	Review for TAA refactor and TAA upsample shader: Brian.Karis

  MAJOR FEATURES & CHANGES
============================

	#jira UE-42783

Change 3454934 by Chris.Bunner

	#jira UE-44405

Change 3512288 by Rolando.Caloca

	DR - Fix issue when recycling image handles

Change 3512338 by Michael.Lentine

	Fix precision if user enters a multiple of 90 degree rotation for transforms.

	This will only work for exact values. Generally comparing float point numbers using == is unsafe but it should be ok in this case as they are exact values entered from the UI. We may want to later expand this to include thresholding using a value ~1e-7.

	#jira UE-46137

Change 3513112 by Richard.Wallis

	Crash when packaging for iOS with Shared Material Native Libraries and Share Material Shader Code from windows platform.  Offline shader compile for archiving not done - shader header has missing offline compile flag for native Metal library archiving.

	Fix includes:
	- Handle offline compile failure when not running on Mac and no remote is configured (or remote fails). (I think it's this point at which the crash in the bug report is at).
	- Make sure remote can build for native Metal libraries and archive correctly - this should now support Linux platforms or Mac to Mac (if enabled in MetalShaderCompiler.cpp) for testing if required.
	- Updated to include remote calling into the xcode 9 Metal pch fix already submitted by Mark Satt.

	#jira UE-45657

Change 3513357 by Richard.Wallis

Change 3517039 by Yujiang.Wang

	GitHub #2655: Optimization for shadow map resolution selection for spot lights

	* Use the radius of the inscribed sphere at the cone end as the spot light's screen radius

	Note: slight drop of shadow quality of spot lights may occur when they are far away from the camera. This is intended, since before this optimization they tend to be always rendered with the maximum shadow map resolution (2048), which is very costly

	#jira UE-33982

Change 3517069 by Yujiang.Wang

	Fix for ScissorRect settings in d3d11 being lost under certain scenarios

	* Scissor rectangle is always enabled in the low-level d3d11 pipeline, and it is expected that at least one ScissorRect is present no matter whether RHISetScissorRect is called with bEnable=false (when it is false we just use a big rect to make it effectively disabled)
	* However FD3D11StateCacheBase::ClearState() clears all the states, which removes scissor rectangles and causes problems for certain routines (FScene::UpdateSkyCaptureContents)
	* Now SetScissorRectIfRequiredWhenSettingViewport will always set a effectively disabled ScissorRect on each FD3D11DynamicRHI::RHISetViewport call, just like d3d12 does

	#jira UE-45465 UE-44760

	#jira UE-46505

Change 3520849 by Uriel.Doyon

	* A new, scalable, platform-independent IssueLongGPUTask is now implemented in UtilityShaders
	* Removed IssueLongGPUTask and G*Vector4VertexDeclaration from RHI implementations
	* The measurement of the execution time of a basic LongGPUTask unit is kicked off on the very first frame

Change 3525346 by Rolando.Caloca

	DR - Fix linking issue

Change 3525459 by Daniel.Wright

	Volumetric Lightmaps - higher quality precomputed GI on dynamic objects and GI on Volumetric Fog
	* Enabled by default on all maps, effective after a lighting build.  This replaces the existing Precomputed Light Volume and Indirect Lighting Cache features.
	* New Lightmass World Settings: VolumeLightingMethod, VolumetricLightmapDetailCellSize and VolumetricLightmapMaximumBrickMemoryMb.
	* Lightmass computes lighting samples in an adaptive grid, with higher density around geometry inside the importance volume.  Positions outside the importance volume get lit with the border texels.
	* Improved Lightmass volume solver to use importance photons and full adaptive final gather, so volume samples have similar quality to 2d lightmaps.
	* A static indirection texture is built covering the importance volume and flattening the brick tree by storing the offset to the highest density brick at each indirection cell.
	* Seamless and efficient GPU interpolation across density levels is achieved by adding a single row of padding to bricks, copied from neighbors, and stitching up bricks with lower density neighbors
	* The Volumetric lightmap stores Irradiance as a 3 band SH, which is 27 floats, quantized into 28 bytes, 7 texture lookups.
	* A full screen barebones material using Volumetric Lightmaps costs .42ms on 970 GTX, while Indirect Lighting Cache Point costs .32ms
	* Sky bent normal is also stored for stationary skylights and Directional Light Shadowing for Single Sample Shadow receiving.
	* Volumetric fog, Movable components, unbuilt Static Components, SingleSampleShadow receiving and Capsule Shadows use Volumetric Lightmaps if available
	* New Visualization show flag for Volumetric Lightmap sample points
	* Level streaming of volume light data is not currently supported with this method

Change 3525461 by Daniel.Wright

	Lowered default r.Shadow.RadiusThreshold for Epic shadow settings as it was causing a lot of visible artifacts from small objects popping out.  This will increase shadowmap cost slightly (13.5ms RT -> 14.3ms RT in Fortnite on PS4, no measurable GPU difference).

Change 3526459 by Rolando.Caloca

Change 3531357 by Michael.Trepka

	Updated Mac glslang libraries with latest changes. Also, updated the Xcode project (generated with CMake) and moved it to a different location so that it no longer uses hardcoded absolute paths. It should be easy to rebuild these libraries in the future.

	Submitted on Richard Wallis's behalf as he's on holiday:

	Mac fixes for Compute Skin Cache rendering issues (resulting in incorrect positions and tangents) and for recomputing tangents.  Problem sampling from buffers/textures as floats with packed data.  Some of the data appears as denorms so get flushed to zero then reinterpreted as uints via asuint or in Metal as_type<uint>().  Fix here for Metal seems to be to use uint types for the skin cache SRV's and as_type<> to floats instead.

	There could be some other areas where we're unpacking via floats that could affect Metal and I'm not sure how this will impact on other platforms.

	#jira UE-48748

Change 3606009 by Mark.Satterthwaite

	Correctly implement ClipDistance for Metal as an array of floats as required by the spec. and fix a few irritating issues from the merge that should not have.
	- When compiling a tessellation vertex shader in the SCW direct mode we can't evaluate non-existant defines and we don't actually need to.
	- The define names, values & shader file name are irrelevant to the Metal output key, but the shader format name & Metal standard really do matter - should speed up Metal shader compilation a bit.
	- Move the shader vertex layer clip-distance to index 2 to avoid conflicts.
	- Don't default initialise the debug code string for Metal shaders or it won't print out the actual code....

	Tested in PIE, engine (cooked, packaged)

Change 3388819 on 2017/04/11 by Arne.Schober

	DR - Faster MorpthTarget implementation. Changed the previous Gather aproach to a scatter based one. Reaching about 110GB/s on PS4 which is up to 4x faster than the previous implementation. On PC DX11 the impact is lower due to unecessary UAV barriers but still 2x faster on AMD and up to 6x faster on Nvidia Hardware.
	#RB Lina.Halper, Rolando.Caloca

	DR - Fix crash when opening a Level without Contentbrowser open.
	#RB Matt.Kuhlenschmidt

Change 3389400 on 2017/04/11 by Uriel.Doyon

	- Renamed FMaterialResource::IsSeparateTranslucencyEnabled() to FMaterialResource::IsTranslucencyAfterDOFEnabled()
	- Removed different logic to determine if translucency after DOF was enabled, and centralized it into a single function: FSceneViewFamily::AllowTranslucencyAfterDOF()
	- FSceneRenderTargets::FinishRenderingSeparateTranslucency() now only resolves a single view, allowing better Begin/Finish scopes.
	- Renamed FSceneRenderTargets::SeparateTranslucencyDepthRT into FSceneRenderTargets::DownsampledTranslucencyDepthRT since this one is only allocated when rendering in downsampled mode.
	- Standard translucency is now rendered in the same resolution than translucency after DOF. (downsampled or full resolution)
	- Removed RenderTranslucencyParallel and merged it's logic into RenderTranslucency. Renamed DrawAllTranslucencyPasses to RenderViewTranslucency and added a parallel version RenderViewTranslucencyParallel.
	- Moved all debug draw logic (VisualizeLPV, ViewMeshElements and SimpleElementCollector) to a common place.
	- New option "r.AllowDownsampledStandardTranslucency" to control the downsampling of standard translucency. Affect blend module materials

Change 3404591 on 2017/04/21 by Olaf.Piesche

	#jira UE-41979
	Should never be crashing there, unless the mesh is changed after Init of the effect instance; this change safeguards against the number of mesh sections (and hence materials) changing after creation of the dynamic data to avoid the crash.

Change 3407451 on 2017/04/25 by Daniel.Wright

	Fixed Indirect Lighting Cache updates caused by capsule indirect shadows forcing point samples, breaking primitives using ILCQ_Volume

Change 3407452 on 2017/04/25 by Daniel.Wright

	Added r.AOJitterConeDirections, although disabled by default because it requires the temporal filter to be much stronger

Change 3408397 on 2017/04/25 by Daniel.Wright

	ViewFamily.bRealtimeUpdate is set to false if Slate is throttling (like when toggling show flags).  Volumetric fog discards the temporal history when not realtime, so you can see changes immediately.

Change 3408428 on 2017/04/25 by Daniel.Wright

	Changed 'r.AOMaxObjectsPerCullTile' default back to 512 as 256 causes artifacts with RTDF shadows

Change 3409764 on 2017/04/26 by Daniel.Wright

	Force dumping shader debug info for Global shaders when r.ShaderDevelopmentMode is enabled.  Most of the shaders you want to look at in a GPU capture are global shaders, and global shaders create few debug files.  'recompileshaders global' time 35s -> 38s for SM5.

Change 3411659 on 2017/04/27 by Daniel.Wright

	[Copy] Set Xbox One engine default screen percentage to 83.33 (1600x900), as ESRAM choices are dependent on this

Change 3411660 on 2017/04/27 by Daniel.Wright

	[Copy] Global distance field composite shader has a version for each flattened axis, which improves efficiency when updating a slab which is what camera movement typically causes

Change 3411667 on 2017/04/27 by Daniel.Wright

	[Copy] Discard distance field AO history buffer if it doesn't match the new buffer size.  This prevents reading uinitialized data after a scene render target resize.

Change 3411668 on 2017/04/27 by Daniel.Wright

	[Copy] Better indirect capsule shadow draw event info

Change 3411669 on 2017/04/27 by Daniel.Wright

	[Copy] Pass down FeatureLevel to AddSubjectPrimitive and GatherShadowsForPrimitiveInner instead of calling the scene's virtual function.  Showed up prominently in a sampling profile.

Change 3411755 on 2017/04/27 by Daniel.Wright

	[Copy] Occlusion queries are now always done before the base pass if a nearly full prepass is being used(DDM_AllOccluders or DDM_AllOpaque)
	* Removed r.OcclusionQueryLocation

Change 3411827 on 2017/04/27 by Daniel.Wright

	[Copy] Much cheaper implementation of IsForwardShadingEnabled which showed up prominently in sampling profiles - inlined function and no more unnecessary thread safety overhead

Change 3411829 on 2017/04/27 by Daniel.Wright

	Added an ensure to console manager when doing FindTConsoleVariableData* on a FAutoConsoleVariableRef

Change 3411837 on 2017/04/27 by Daniel.Wright

	[Copy] Worked around slow memcpy's being used to sort FSortedLightSceneInfo

Change 3411838 on 2017/04/27 by Daniel.Wright

	[Copy] Skip tracking MaterialRenderProxyMap on cooked platforms

Change 3411843 on 2017/04/27 by Daniel.Wright

	[Copy] Fixed r.ParallelShadows on PS4 and enabled by default engine-wide (saves 5ms RT with CSM)
	* Gnm was not tracking DepthClearValue when a depth target was set but not cleared
	* Gnm has a bug where TargetsNeedingEliminateFastClear does not persist across commandlist breaks.  Moved FinishRenderingGBuffer before RenderShadowDepthMaps to workaround (accidentally not in this changelist)
	* Shadow depth rendering was not using BindClearMRTValues to populate GNM parallel commandlist TargetsNeedingEliminateFastClear values

Change 3411873 on 2017/04/27 by Daniel.Wright

	[Copy] Deferred uniform expression caching.  Setting multiple parameters on a material only causes its uniform expressions to be recached once.
	* 280 calls to CacheUniformExpressions -> 120 during Fortnite combat (6.5ms -> 3.4ms)

Change 3411891 on 2017/04/27 by Daniel.Wright

	[Copy] GatherShadowPrimitives optimizations
	* Total GatherShadowPrimivies went from 2.3ms -> 1.3ms on PS4 with these changes in GPUPerfTest (duplicated 3x)
	* Much flatter primitive octree (16 -> 256 max primitives)
	* Primitives are culled against the shadow frustum before FPrimitiveSceneInfo or FPrimitiveSceneProxy are dereferenced in FilterPrimitiveForShadows
	* FilterPrimitiveForShadows work is done in a ParallelFor.  Primitive octree nodes are processed in different jobs.
	* StaticMeshWholeSceneShadowBatchVisibility now only stores entries for meshes with bRequiresPerElementVisibility (landscape).  Previously it was allocating and zeroing 500Kb 3x per frame (main view + 2 cascades) which cost ~.8ms on PS4.

Change 3412192 on 2017/04/27 by Michael.Trepka

	Fixed Clang compile errors in FortniteGame, partial copy of CL 3313426

Change 3412547 on 2017/04/27 by Daniel.Wright

	#RB none
	#jira UE-44500

Change 3414754 on 2017/04/28 by Daniel.Wright

	Added VolumetricFogEmissive to ExponentialHeightFogComponent
	* Volumetric fog does not yet support precomputed lighting, so this is the only way to get an ambient lighting term

Change 3431667 on 2017/05/09 by Daniel.Wright

	Volumetric fog now supersamples lighting when the history is not available, reducing noise on areas that just came on-screen or after a camera cut.
	* The number of samples is controlled by r.VolumetricFog.HistoryMissSupersampleCount, defaults to 4, cinematic scalability uses 16
	* Under fast camera movement, volumetric fog cost went from 1.79ms -> 1.97ms with 4 samples, on a 970GTX

Change 3432366 on 2017/05/10 by Richard.Wallis

	Fix for MetalRHI Asserts When Using "Profile GPU" With RHI-Thread/Parallel-Execution.  Don't insert events when not in RHIThread or the actual single-threaded-render thread.

	#jira UE-36006

Change 3432367 on 2017/05/10 by Richard.Wallis

	Fix for Metal ReStartRenderPass assert with profiling.  macOS metal asserts when using "profileGPU" even with -norhithread argument set.

	Added no action to the allowed render pass restart store actions for the depth buffer avoiding the assert.  Interested to know the details if this is not a valid assumption to make - throwing away the depth buffer after a render pass I think would be a common case.

	#jira UE-44322

	Fix for shared Material Native Shader Libraries Don't Function With Iterative Cooking.   Keep latest versions of shader byte code in native shared material packaged build in an intermediate directory than can be reused on a later iterative cook.

	- Doesn't handle deletion of the intermediate directory contents.  Assumed to be a higher level requirement on non iterative cook flag.

	Skip recapturing reflection captures when PropagateLightingScenarioChange is being called for a level unload.  This leaves stale results in reflection captures around when hiding a level in the editor, but avoids the double recapture that happens when swapping lighting scenarios in game, and the unnecessary reflection capture update when exiting PIE.

	Crash fix.
	Issue found in https://udn.unrealengine.com/questions/355944/crash-in-fdynamicspriteemitterdatagetdynamicmeshel.html

	Particle proxies would have stale material resource pointers if the material is changed while the system was invisible.

	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.

Change 3235397 on 2016/12/14 by Keli.Hlodversson

	#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.

	3278536

	* 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

	UEVR-9 PSVR: Social Screen Support
	-Experimental social screen support for 4.16.
	-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.

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

Change 3219796 on 2016/12/02 by Rolando.Caloca

	DR - vk - Increase timeout to 60ms

Change 3219884 on 2016/12/02 by Daniel.Wright

	Assert to help track down rare crash locking capsule indirect shadow vertex buffer

Change 3219885 on 2016/12/02 by Daniel.Wright

	Fixed saving a package that doesn't exist on disk but exists in p4 at a newer revision when the user chooses 'Mark Writable'

Change 3219886 on 2016/12/02 by Daniel.Wright

	Don't create projected shadows when r.ShadowQuality is 0
	* Fixes crash in the forward path trying to render shadows
	* In the deferred path, the shadowmap was still being rendered and only the projection skipped, now all cost will be skipped

Change 3219887 on 2016/12/02 by Daniel.Wright

	Changed ClearRenderTarget2D default alpha to 1, which is necessary for correct compositing

Change 3219893 on 2016/12/02 by Daniel.Wright

	AMD AGS library with approved TPS
	Disabled DFAO on AMD pre-GCN PC video cards to workaround a driver bug which won't be fixed (Radeon 6xxx and below)

Change 3219913 on 2016/12/02 by Daniel.Wright

	Level unload of a lighting scenario propagates the lighting scenario change - fixes crash when precomputed lighting volume data gets unloaded

Change 3220029 on 2016/12/02 by Daniel.Wright

	Async shader compiling now recreates scene proxies which are affected by the material which was compiled.  This fixes crashes which were occuring as proxies cache various material properties, but applying compiled materials would not update these cached properties (bRequiresAdjacencyInformation).
	* A new ensure has been added in FMeshElementCollector::AddMesh and FBatchingSPDI::DrawMesh to catch attempts to render with a material not reported in GetUsedMaterials
	* Fixed UParticleSystemComponent::GetUsedMaterials and UMaterialBillboardComponent::GetUsedMaterials
	* FMaterialUpdateContext should be changed to use the same pattern, but that hasn't been done yet

Change 3220108 on 2016/12/02 by Daniel.Wright

	Fixed shadowmap channel assignment for stationary lights which are not in a lighting scenario level, when a lighting scenario level is present

Change 3220504 on 2016/12/03 by Mark.Satterthwaite

	Metal Desktop Tessellation support from Unicorn.
	- Apple: Metal tessellation support added to MetalShaderFormat, MetalRHI and incl. changes to engine runtime/shaders for Desktop renderer and enabled in ElementalDemo by default (OS X 10.11 will run SM4).
	- Epic: Support for different Metal shader standards on Mac, iOS & tvOS which required moving some RHI functions around as this is a project setting and not a compile-time constant.
	- Epic: Fragment shader UAV support, which is also tied to newer Metal shader standard like Tessellation.
	- Epic: Significant refactor of MetalRHI's internals to clearly separate state-caching from render-pass management and command-encoding.
	- Epic: Internal MetalRHI validation code is now cleanly separated out into custom implementations of the Metal @protocol's and is on by default.
	- Epic: Various fixes to Layered Rendering for Metal.
	- Omits Mobile Tessellation support which needs further revision.

Change 3220881 on 2016/12/04 by Mark.Satterthwaite

	DR - Lambdaize
	- Added quicker method to check if system textures are initialized

Change 3222290 on 2016/12/05 by Mark.Satterthwaite

	Trivial fixes to reporting Metal shader pipeline errors - need to check if Hull & Domain exist.

Change 3222864 on 2016/12/06 by Rolando.Caloca

	Moved HLOD persistent data to viewstate to fix per-view compatability.
	#jira UE-37539

Change 3223349 on 2016/12/06 by Chris.Bunner

	Fixed HLOD with FreezeRendering command.
	#jira UE-29839

Change 3223371 on 2016/12/06 by Michael.Trepka

	Removed obsolete check() in FMetalSurface constructor

Change 3223450 on 2016/12/06 by Chris.Bunner

	Added explicit ScRGB output device selection rather than Nvidia-only hardcoded checks. Allows easier support for Mac and other devices moving forward.

Change 3223638 on 2016/12/06 by Michael.Trepka

	Restored part of the check() in FMetalSurface constructor removed in CL 3223371

Change 3223642 on 2016/12/06 by Mark.Satterthwaite

	Experimental Metal EDR/HDR output support for Mac (iOS/tvOS need custom formats & shaders so they are not supported yet).
	- Only available on macOS Sierra (10.12) for Macs with HDR displays (e.g. Retina iMacs).
	- Enable with -metaledr command-line argument as it is off-by-default.
	- Sets up the CAMetalLayer & the back-buffer for RGBA_FP16 output on Mac using DCI-P3 as the color gamut and ACES 1000 nit ScRGB output encoding.

Change 3223830 on 2016/12/06 by Rolando.Caloca

	DR - vk - Better error when finding an invalid Vulkan driver
	#jira UE-37495

Change 3223869 on 2016/12/06 by Rolando.Caloca

	DR - vk - Reuse fences

Change 3223906 on 2016/12/06 by Guillaume.Abadie

	Fix alpha through TempAA artifact causing a small darker edge layouts.

Change 3224199 on 2016/12/06 by Mark.Satterthwaite

	Fix a dumb copy-paste error from the HDR changes to Metal.

Change 3224220 on 2016/12/06 by Mark.Satterthwaite

	Fix various errors with Metal UAV & Render-Pass Restart support so that we can use the Pixel Shader culling for DistanceField effects.
	- Unfortunately Metal requires that a texture be bound to start a render-pass, so reuse the dummy depth-stencil surface from the problematic editor preview tile rendering.

Change 3224236 on 2016/12/06 by Mark.Satterthwaite

	IWYU CIS compile fix for iOS.

Change 3224366 on 2016/12/06 by Mark.Satterthwaite

	Simplify some of the changes from CL# 3224220 so that we don't perform unnecessary clears.
	- If the RenderPass is broken to issue compute or blit operations then treat the cached RenderTargetsInfo as invalid, unless the RenderPass is restarted.
	- This guarantees that we don't erroneously ignore calls to SetRenderTargets if the calling code issues a dispatch between two RenderPasses that use the same RenderTargetsInfo.

Change 3224416 on 2016/12/06 by Uriel.Doyon

	New default implementation for UPrimitiveComponent::GetStreamingTextureInfo using a conservative heuristic where the textures are stretched across the bounds.
	Optimized UPrimitiveComponent::GetStreamingTextureInfoWithNULLRemoval by not handling registered components with no proxy (essentially hidden game / collision primitives).

	Added blueprint support for texture streaming built data through FStaticMeshComponentInstanceData.

	Fix for material texture streaming data not being available on some cooked builds.

	Enabled split requests on all texture load requests (first loading everything visible and then loaded everything not visible).
	This is controlled by "r.Streaming.MinMipForSplitRequest" which defines the minimum mip for which to allow splitting.
	Forced residency are now loaded in two steps (visible, then forced), improving reactiveness.

	Updated "stat streaming" to include "UnkownRefMips" which represent texture with no known component referencing them,
	and also "LastRenderTimeMips" which related to timed primitives.
	Changed "Forced Mips" so that it only shows mips that are loaded become of forced residency.

	"Texture Streaming Build" now updates the map check after execution.

	Removed Orphaned texture logic as this has  become irrelevant with the latest retention priority logic.

	Updated "r.streaming.usenewmetrics" so that it shows behavior before and after 4.12 improvements.

Change 3224532 on 2016/12/07 by Uriel.Doyon

	Integrated CL 3223965 :

	Building texture streaming data for materials does not wait for pending shaders to finish compilation anymore.
	Added more options to allow the user to cancel this build also.

Change 3224714 on 2016/12/07 by Ben.Woodhouse

	Cherry pick CL 3223972 from //fortnite/main:

	Disable Geometry shader onchip on XB1. This saves 4ms for a single shadow casting point light @ 512x512 (4.8ms to 1.8ms)

Change 3224715 on 2016/12/07 by Ben.Woodhouse

	New version of d3dx12.h from Microsoft which incorporates my suggested static analysis fixes. This avoids us diverging from the official version

Change 3224975 on 2016/12/07 by Rolando.Caloca

	DR - vk - Dump improvements

Change 3225012 on 2016/12/07 by Rolando.Caloca

	DR - Show warning if trying to use num samples != (1,2,4,8,16)

Change 3225126 on 2016/12/07 by Chris.Bunner

	Added 'force 128-bit rendering pipeline' to high-res screenshot tool.
	#jira UE-39345

Change 3225449 on 2016/12/07 by Chris.Bunner

	#jira UE-38081

Change 3225485 on 2016/12/07 by Chris.Bunner

	#jira UE-19394

Change 3225486 on 2016/12/07 by Chris.Bunner

	Only disable TAA during HighResScreenshots if we don't have a reasonable frame-delay enabled.

Change 3225505 on 2016/12/07 by Daniel.Wright

	Fixed exponential height fog disappearing with no skybox

Change 3225655 on 2016/12/07 by Benjamin.Hyder

	Dirty owning packages when user manually forces regeneration of all reflection captures.
	#jira UE-38759

Change 3226139 on 2016/12/07 by Rolando.Caloca

	DR - Fix recompute tangents disabling skin cache
	- Make some macros into lambdas
	#jira UE-39143

Change 3226212 on 2016/12/07 by Daniel.Wright

	Features which require a full prepass use DDM_AllOpaque instead of DDM_AllOccluders, which can be skipped if the component has bUseAsOccluder=false

Change 3226213 on 2016/12/07 by Daniel.Wright

	Scene Capture 2D can specify a global clip plane, which is useful for portals
	* Requires the global clip plane project setting to be enabled

Change 3226214 on 2016/12/07 by Daniel.Wright

	Improved deferred shadowing with MSAA by upsampling light attenuation intelligently in the base pass
	* If the current fragment's depth doesn't match what was used for deferred shadowing, the neighbor (cross pattern) with the nearest depth's shadowing is used
	* Edge artifacts can still occur where the upsample fails or the shadow factor was computed per-sample due to depth / stencil testing
	* Indirect Occlusion from capsule shadows also uses the nearest depth neighbor UV for no extra cost
	* Base pass on 970 GTX 1.69ms -> 1.85ms (.16ms) in RoboRecall

Change 3226258 on 2016/12/07 by Rolando.Caloca

	DR - Typo fix

	Re-saved Infiltrator maps to update reflection captures.
	#jira UE-38759

Change 3227063 on 2016/12/08 by Mark.Satterthwaite

	For Metal platforms ONLY temporarily disable USE_LIGHT_GRID_REFLECTION_CAPTURE_CULLING to avoid UE-37436 while the Nvidia driver team investigate why this doesn't work for them but does for the others. This won't affect non-Metal platforms and the intent is to revert this prior to 4.16 provided we can work through the problem with Nvidia.
	#jira UE-37436

Change 3227120 on 2016/12/08 by Gil.Gribb

	Merging //UE4/Dev-Main@3226895 to Dev-Rendering (//UE4/Dev-Rendering)

Change 3227211 on 2016/12/08 by Arne.Schober

	Extension to PseudoVolumeTexture for more flexible layout
	Change by ryan.brucks

	#jira UE-39311

Change 3227376 on 2016/12/08 by Mark.Satterthwaite

	Must not include a private header inside the MenuStack public header as that causes compile errors in plugins.

Change 3227415 on 2016/12/08 by Mark.Satterthwaite

	Fix shader compilation due to my disabling of USE_LIGHT_GRID_REFLECTION_CAPTURE_CULLING on Metal - InstancedCompositeTileReflectionCaptureIndices needs to be defined even though Metal doesn't support instanced-stereo rendering.

Change 3227516 on 2016/12/08 by Daniel.Wright

	Implemented UWidgetComponent::GetUsedMaterials

Change 3227521 on 2016/12/08 by Guillaume.Abadie

	Fixes post process volume's indirect lighting color.

	#jira UE-38888

Change 3227567 on 2016/12/08 by Marc.Olano

	New upscale filters: Lanczos-2 (new default), Lanczos-3 and Gaussian Unsharp Mask

Change 3227628 on 2016/12/08 by Daniel.Wright

	Removed redundant ResolveSceneDepthTexture from the merge

Change 3227635 on 2016/12/08 by Daniel.Wright

	Forward renderer supports shadowing from movable lights and light functions
	* Only 4 shadow casting movable or stationary lights can overlap at any point in space, otherwise the movable lights will lose their shadows and an on-screen message will be displayed
	* Light functions only work on shadow casting lights since they need a shadowmap channel to be assigned

Change 3227660 on 2016/12/08 by Rolando.Caloca

	DR - vk - Fix r.MobileMSAA on Vulkan
	- r.MobileMSAA is now read-only (to be fixed on 4.16)
	- Show time for PSO creation hitches
	#jira UE-39184

Change 3227704 on 2016/12/08 by Mark.Satterthwaite

	Fix Mac HDR causing incorrect output color encoding being used, HDR support is now entirely off unless you pass -metaledr which will enable it regardless of whether the current display supports HDR (as we haven't written the detection code yet). Fixed the LUT/UI compositing along the way - Mac Metal wasn't using volume LUT as it should have been, RHISupportsVertexShaderLayer now correctly returns false for non-Mac Metal platforms.

Change 3227705 on 2016/12/08 by Daniel.Wright

	Replaced built-in samplers in the nearest depth translucency upsample because the built-in samplers are no longer bound on PC (cl 2852426)

Change 3227787 on 2016/12/08 by Chris.Bunner

	Added extent clear to motion blur pass to catch misized buffers bringing in errors.
	Added early out to clear call when excluded region matches RT region.
	#jira UE-39437

	Merging //UE4/Dev-Main@3228528 to Dev-Rendering (//UE4/Dev-Rendering)

Change 3228940 on 2016/12/09 by Mark.Satterthwaite

	Editor fixes for 4.15:
	- PostProcessTonemap can't fail to bind a texture to the ColorLUT or the subsequent rendering will be garbage: the changes for optimising stereo rendering forgot to account for the Editor's use of Views without States for the asset preview thumbnails. Amended the CombineLUT post-processing to allocate a local output texture when there's no ViewState and read from this when this situation arises which makes everything function again.
	- Don't start render-passes without a valid render-target-array in MetalRHI.

Change 3228950 on 2016/12/09 by Mark.Satterthwaite

	Make GPUSkinCache run on Mac Metal - it wasn't working because it was forcibly disabled on all platforms but for Windows D3D 11.
	- Fixed the Skeleton editor tree trying to access a widget before it has been constructed.
	- Enable GPUSkinCache for Metal SM5: doesn't render correctly, even on AMD, so needs Radar's filing and investigation.
	#jira UE-39256

	XB1 D3D11 and D3D12: Use the DXGI frame statistics to get accurate GPU time unaffected by bubbles

Change 3229430 on 2016/12/09 by Ben.Woodhouse

	PR #2680: Optimized histogram generation. (Contributed by PjotrSvetachov)

	Profiled on nvidia 980GTX (2x faster), and on XB1 (marginally faster)

Change 3229580 on 2016/12/09 by Marcus.Wassmer

	DepthBoundsTest for AMD.

Change 3229701 on 2016/12/09 by Michael.Trepka

	Changed "OS X" to "macOS" in few places where we display it and updated the code that asks users to update to latest version to check for 10.12.2

Change 3229706 on 2016/12/09 by Chris.Bunner

	Added GameUserSettings controls for HDR display output.
	Removed Metal commandline as this should replace the need for it.

Change 3229774 on 2016/12/09 by Michael.Trepka

	Disabled OpenGL on Mac. -opengl is now ignored, we always use Metal. On old Macs that do not support Metal we show a message saying that the app requires Metal and exit.

Change 3229819 on 2016/12/09 by Chris.Bunner

	Updated engine rendering defaults to better match current best practices.

	DR - Fix d3d debug error
	#jira UE-39589

Change 3230341 on 2016/12/11 by Mark.Satterthwaite

	Don't fatally assert that the game-thread stalled waiting for the rendering thread in the Editor executable, even when running -game as the rendering thread can take a while to respond if shaders need to be compiled.
	#jira UE-39613

Change 3230860 on 2016/12/12 by Marcus.Wassmer

	Experimental Nvidia AFR support.

Change 3230930 on 2016/12/12 by Mark.Satterthwaite

	Disable RHICmdList state-caching on Mac - Metal already does this internally and depends on receiving all state changes in order to function.

Change 3231252 on 2016/12/12 by Marcus.Wassmer

	Fix NumGPU detection. (SLI only crash)

Change 3231486 on 2016/12/12 by Mark.Satterthwaite

	Fix a stupid mistake in MetalStateCache::CommitResourceTable that would unnecessarily rebind samplers.

Change 3231661 on 2016/12/12 by Mark.Satterthwaite

	Retain the RHI samplers in MetalRHI to guarantee lifetime.
