c72b7a33d8 Merging //UE4/Dev-Rendering-Graph@4492585 to Dev-Rendering (//UE4/Dev-Rendering)
This implements the framework to write the high level rendering code into passes organized in direct acyclic graph. It is also unifying the uniform buffer, shader parameters, and pass parameters to same single API: structures with run time meta data. This allow high level user code be extremely seamless, user code debugging, and render graph ease of implementation and debugging.

Issue of collaborative work of Arne Schnober, Brian Karis, Daniel Wright, Marcus Wassmer and Guillaume Abadie.

Names of the graph managed resources are not final.

	#jira UE-53483

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.

	D3D12 RHI: only refcount uniform buffers if GRHINeedsExtraDeletionLatency is false, which is no longer the case for PC or Xbox.

Change 3844946 by Mark.Satterthwaite

	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.

Change 3853945 by Mark.Satterthwaite

	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.

	#jira UE-53720

Change 3853966 by Mark.Satterthwaite

	Duplicate #3835852

	Fix tessellation shaders in Metal with Manual Vertex Fetch enabled:
	- The control points idnex buffer shouldn't collide with anything else.
	- 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

	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.

	Fixed crashes inside RemoveSpeedTreeWind() and RemoveSpeedTreeWind_RenderThread().
	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()

	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.
	- Renamed a variable in the AvfMediaVideoSample - was called FrameRate but it was the FrameDuration by that point.

	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.

	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.

	[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.

	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.

Change 3587943 by Luke.Thatcher

	[CONSOLE] [+] Improved XGE shader compiler
	 - Added support for XGE interception interface, which allows asynchronous streaming of shader tasks into XGE, and eliminates the stalling/flushing found in the old system.
	 - Old system has been renamed "Xml interface"
	 - Both systems are available and selectable based on r.XGEShaderCompile.Mode CVar.

	Overview of the new system:
	 - New system uses an additional XGEControlWorker process to manage communication between the engine and XGE. This is simply a copy of ShaderCompileWorker.exe (the implementation is part of SCW, but XGE requires the two files to be separate, hence the duplicate).
	 - When shader jobs arrive from the engine, the shader compiler thread spawns an instance of XGEControlWorker within an XGE context, and connects to it via named pipes.
	 - Job command lines are fed to the control worker via the pipe, which the worker enqueues within XGE by issuing a CreateProcess call, which is intercepted. Job completion is reported back to the engine via the named pipes.

	 - New system is preferred over the old one, and is enabled with "-xgeshadercompile" command line switch or "r.XGEShaderCompile" cvar.
	 - The new system depends on the "XGEController" engine module. Support for which is based on the WITH_XGE_CONTROLLER #define, or -xgecontroller/-noxgecontroller command line options.

Change 3624878 by Ben.Woodhouse

	Integrate as edit CLs 3611835 3611844 3616942 3617607
	Descriptor heap memory fix (saves up to ~100MB).
	 * Fix a bug where rolling over a thread-local heap immediately after switching to context-local would crash due to an uninitialized syncpoint
	 * Add a separate value for context local heaps (LOCAL_HEAP_SIZE) and set it to a sensible value (2MB) instead of the current 16MB. This means thread local heaps will be allocated in chunks of ~2MB instead of 16MB. There can be up to 6 thread-local heaps, since they're per-context.

	Measured peak descriptor heap memory with LLM: 45MB (compared to 145MB previously)

	This improves behaviour, but this code could use a bit of a rewrite to allow it to reclaim memory better. For example, the global heap memory is almost entirely wasted currently, since when a context switches to "context local strategy" it simply throws this memory away, never to be reclaimed. Having the pools thread-local is also not a good strategy. Ideally we want a thread-safe pool allocator for descriptor heaps which is shared between all the contexts .

	Fix virtual destructor warning in D3DX12.h

Change 3626419 by Stewart.Lynch

	Merging
	//Fortnite/Main/...

	to //UE4/Dev-Console/...

	LLM Update - Memory reductions, Summary page, enum scopes, refactor and cleanup of tags

	* Remove all static arrays and hard limits from LLM. Everything is now dynamically allocated using the internal LLM allocators. The overhead when LLM is disabled is now only 48K (was 40MB)
	* re-wrote LLMMap. Now stores an int32 index rather then pointer in the HashMap array. Also, changed the Values to be arrays for structs instead of structs of arrays. Means that the tag can be stored in a single byte. Changed the size of the allocation size from int64 to int32. All this takes the memory down from around 600MB to 100MB. It was 120 bytes per allocation, now 29 bytes.
	* changed all LLM scopes over to enums. This has a number of benefits; LLM can be enable in Test, less CPU overhead, stored in a byte (LLM overhead /= 8)
	* summary page for content creators where all lower-level stats are grouped under one Engine stat
	* renamed ELLMScopeTag enum to ELLMTag
	* renamed LLM_SCOPED_TAG_WITH_ENUM macro to LLM_SCOPE
	* removed Tracker arg from LLM_SCOPE and added LLM_PLATFORM_SCOPE macro
	* fixed GenericPlatformMallocCrash stat. Although it seems not be be used anymore
	* fixed BackupOOMMemoryPool stat (now shows in both default and platform pages)
	* lots of changes adding/removing/renaming tags
	* added LLMArray and FLLMObjectAllocator classes
	* disabled asset tag tracking by default because it takes up so much memory even when not used
	* enable LLM in all non-shipping builds. In Test the on screendisplay won't show because it uses the stats system but it till still write out the csv.
	* all the stat macros have been left as they were and can be enabled on the LLM_STAT_TAGS_ENABLED define. These are needed for the asset tagging.
	* disabled LLM_TRACK_PEAK_MEMORY because there is a problem with the way it adds the peaks for multiple threads. This needs to be fixed.
	* added a CVar to control the csv write interval: LLM.LLMWriteInterval
	* added static arrays for the enum tags setup. Easier to manage and removes need for slow switch statements.
	* renamed FLLMThreadStateManager to FLLMTracker to make it consistent with the enum

	Fixed issue when building distribution lookup tables where the final sample fell short of the max input time.
	As sampling is done only over this range, under constant interpolation the final value was never actually sampled and so cut from the final optimized LUT.

	#tests constant interpolation now works.

	#jira UE-45614

Change 3482965 by Yujiang.Wang

	Some quality of life changes for UE-42757

	Fix for shadow color not updated after light build when a texture is changed and reimported

	* Bug caused by counter-intuitive design of UMaterial::GetReferencedFunctionIds and UMaterial::GetReferencedParameterCollectionIds, both of which will reset the OutIds parameter
	* Renamed to AppendReferencedFunctionIdsTo and AppendReferencedParameterCollectionIdsTo, the resets are removed

	#jira UE-45647

Change 3484969 by Yujiang.Wang

	Fix for UE-39929 inconsistent type between C++ and shader code

	* MeshDistanceFieldCasterIndices is declared as Buffer<uint> in CapsuleShadowShaders.usf, while created as PF_R32_SINT in CapsuleShadowRendering.cpp
	* Changed PF_R32_SINT to PF_R32_UINT in CapsuleShadowRendering.cpp

	Fixes some shader file name casing issues in LPV.

Change 3488014 by Uriel.Doyon

	New AllowAsyncLoading flag for UTexture::CachePlatformData().
	It allows to load the source texture data in the async task if the source bulk data was not yet loaded.

	Data loaded that way is not sharable between tasks and will be discarded.
	This is required because updating the source data is not thread safe.

	#jira UERNDR-190
	#jira UE-33401

Change 3488249 by Uriel.Doyon

	Fixed long stall in UpdateResourceStreaming() caused by Actor.GetComponents() not resetting the number of actors anymore.
	Fixed inconsistent results in ALODActor::HasValidSubActors() caused by the same change.

	#jira UE-46004

Change 3490228 by Mark.Satterthwaite

	Fix the Nvidia driver bug with the old reversebits fallback function - you need to use the native reverse_bits intrinsic or use some uint(ushort()) casts to get the compiler to do the right thing, which means injecting the reverse_bits function in MetalBackend not the HLSL (as it has no such type).

	Project or plugin must be loaded in PostConfigInit phase
	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

Change 3388862 on 2017/04/11 by Guillaume.Abadie

	Allows Motion Blur and TAA in scene capture 2d.

	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

	#RB None
	#jira UE-43898

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

	Fixed leak of FShadowMapAllocation and FLightMapAllocation's found by licensee

Change 3414239 on 2017/04/28 by Arne.Schober

	DR - UE-44500 - Removed use of Structured Buffer from MorphTargets due to HLSLCC not supporting it.

	#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 3416859 on 2017/05/01 by Arne.Schober

	DR - Remove FeatureLevel from the Clear Functions to reduce area of error
	#RB Rolando.Caloca

Change 3431591 on 2017/05/09 by Daniel.Wright

	Disallow map building while in PIE, or PIE while buildling lighting

Change 3431594 on 2017/05/09 by Daniel.Wright

	Added RenderTargetFormat to UTextureRenderTarget2D, with choices of 8 bit, 16fp, 32fp and 1, 2 or 4 channels.

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

Change 3432409 on 2017/05/10 by Richard.Wallis

	Merged across CL 3415890 from Release-4.16 fix for (jira UE-43895)

	Fix for deferred store actions getting cleared when we don't have a valid render target.

	Improved captions for Noise and VectorNoise material nodes

Change 3432947 on 2017/05/10 by Richard.Wallis

	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.

	#jira UE-44657

Change 3433484 on 2017/05/10 by Arne.Schober

	DR - UE-44393 - Move ShaderPlatform into TShaderMap for extra debuginformation when it fails to find a proper shader. Also log when Gobalshaders are verified and recompiled.
	#jira UE-44393
	#RB Daniel.Wright

	Fixed static shadowing of volumetric fog and translucency causing shadowing past the lightmass importance volume.

Change 3433619 on 2017/05/10 by Daniel.Wright

	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.

Change 3433795 on 2017/05/10 by Arne.Schober

	DR - add cmdline to select a GPU vendor when multiple GPUs from differnt Vendors are installed into the same Machine
	#RB marcus.Wassmer

Change 3433941 on 2017/05/10 by Daniel.Wright

	Cone vs tile bounding sphere intersection tests for Light Grid culling of spotlights, which provides much tighter culling than just View space tile AABB vs light bounding sphere.
	* Forward shading BasePass 3.7ms -> 2.4ms in a scene with 24 spotlights on 970GTX
	* Volumetric fog 2.87ms -> 2.09ms in the same scene

Change 3435139 on 2017/05/11 by Daniel.Wright

	Restored GTextureRenderTarget2DMaxSizeX which is used by Ocean

Change 3435297 on 2017/05/11 by Arne.Schober

	DR - Remove manual AlignOf and use C++11 keyword instead
	#RB Steve.Robb

Change 3435367 on 2017/05/11 by Daniel.Wright

	Circle vertex buffer for slightly tighter voxelization of volumetric fog shadowed lights
	* 1.5ms -> 1.38ms on 970 GTX with 24 spotlights

Change 3435522 on 2017/05/11 by Brian.Karis

	Fix for fixed bounds being "invalid" unless set via the toolbar option.

Change 3436700 on 2017/05/12 by Simon.Tovey

	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.
	If the old material is freed during this time, the next time the system renders it will crash.

Change 3437367 on 2017/05/12 by Brian.Karis

	Fixed bug with small UV charts not packing.

Change 3441680 on 2017/05/16 by Uriel.Doyon

	Added units to point light intensity, to allow the user to specify the value in candelas or lumens.
	New point light actors now configure the intensity in candelas by default.
	Replaced viewport exposure settings by an EV100 slider.
	Hidding the tone mapper in the show flag now still applies the exposure.
	Added a new AutoExposure method called EV100 which allows to specify :
	- MinEV100, MaxEV100
	- Calibration Constnat
	- Exposure Compensation

	UE4 - Allowed the possibility of running the RHI "thread" on task threads instead and cleaned up and unified the conditionals involved. By default we still have a dedicated RHI thread because it tested slightly faster.

Change 3443951 on 2017/05/17 by Richard.Wallis

	Added Apple override allocator macro - each command encoder type needs it's own allocator queue.

Change 3444787 on 2017/05/17 by Daniel.Wright

	Fixed DBuffer decal default normal (used when DBuffer decals enabled, but not decals rendered) not reconstructing zero properly, adding -.008 to WorldNormal which then caused artifacts with forward lighting specular on materials with roughness near 0.

Change 3444882 on 2017/05/17 by Daniel.Wright

	Added comment to  FClearValueBinding::DefaultNormal8Bit to make the dependency on shader decode clear

	[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

	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

	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).

	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

Change 3374588 on 2017/03/31 by Richard.Wallis

	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.

	Merging CL 3233886: AMD HDR support (requires r.AMDSupportsHDRDisplayOutput=1 in ini).
	Update to AGS 5.0.5.
	Partial code tidy up.

Change 3310187 on 2017/02/17 by Chris.Bunner

	Preserve constant expressions rather than always casting after translating a material attribute. Losing the notion of constant means we can't correctly detect used properties and falsely enable e.g. PDO. Happened because of the incorrect component masks in BreakMaterialNodes which then had to be downcast to the correct type which is done as an inline fragment rather than swizzle expression.

	#jira UE-41594

Change 3310215 on 2017/02/17 by Chris.Bunner

	[Copy] 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 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.

	[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.

Change 3346526 on 2017/03/14 by Daniel.Wright

	[Copy] Volumetric Fog supports point and spot light shadows
	* These lights are injected separately so that per-light resources can be bound (shadow depth map, static shadow depth map)
	* 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 3232283 on 2016/12/13 by Ben.Woodhouse

	D3D12 - downgrade root signature size warning to a log following a discussion with Microsoft. There's not much we can actually do about it, and it's not relevant to all hardware
	#jira UE-36999

Change 3232641 on 2016/12/13 by Mark.Satterthwaite

	- Eliminate redundant state changes in MetalRHI in the state cache.
	- Add a new debug level for setting buffers to nil prior to calls to set*Bytes so that the tool doesn't display incorrect data.
	- Make testing for validation & statistics features use the same EMetalFeatures API as everything else for consistency.
	- Cache the fallback depth-stencil texture in the state cache and ignore it for determining whether a pass can restart - if we are using this texture its contents are worthless anyway.

Change 3232661 on 2016/12/13 by Mark.Satterthwaite

	Re-enable Metal SM5 & DFAO/DistanceFieldShadowing on Intel for 10.12.2 or later.

Change 3232759 on 2016/12/13 by Ben.Woodhouse

	Fix memory leak on XB1 when calling GPURealloc with count of 0, suggested on UDN
	https://udn.unrealengine.com/questions/326660/gpurealloc-leak.html

Change 3232803 on 2016/12/13 by Ben.Marsh

	Add UT to the populate DDC job, and cook UT and Fortnite for Mac as well.

Change 3232836 on 2016/12/13 by Ben.Marsh

	Split cooks to populate DDC into separate nodes for each platform. May help to reduce number of timeouts on remote VMs.

Change 3232974 on 2016/12/13 by Rolando.Caloca

	DR - Refactor common code to UWorld::RecreateScene
	#jira UE-36719
	PR #2824

Change 3232976 on 2016/12/13 by Ben.Marsh

	Add missing dependency on tools node for Mac cooks. Need to compile SCW first.

Change 3233289 on 2016/12/13 by Olaf.Piesche

	Fixing potentially broken spot/point light fade with old content; initialize new properties properly

Change 3233811 on 2016/12/13 by Mark.Satterthwaite

	Fix compiling QA-Material tessellation shaders that don't need to emit from Hull or sample in Domain the HSOut buffer which was confusing MetalBackend.

Change 3233854 on 2016/12/13 by Mark.Satterthwaite

	More information about texture type validation errors in Metal.

Change 3234650 on 2016/12/14 by Rolando.Caloca

	DR - vk - Fix bad aspect on depth cubemaps

Change 3234651 on 2016/12/14 by Rolando.Caloca

	DR - vk - Fix for 32 bit crash on dump layer

Change 3234813 on 2016/12/14 by Guillaume.Abadie

	Fixes texture mask static lighting when using GBuffer selective outputs.

	#jira UE-39527

Change 3235047 on 2016/12/14 by Uriel.Doyon

	Refactored HLOD texture streaming strategy to separate forced load from visibility.
	Added an incremental update in the last stage of the texture streaming update load to clear any pending work.
	Added an option "All" to the "BuildMateriaTexturelStreamingData" command to force rebuild everything.

Change 3235317 on 2016/12/14 by Uriel.Doyon

	Removed timed primitives in the texture streaming since it was not used and there is now a fallback implementation in UPrimitiveComponent::GetStreamingTextureInfo.

Change 3235431 on 2016/12/14 by Rolando.Caloca

	DR - Fix for Vulkan drawing black

Change 3236788 on 2016/12/15 by Mark.Satterthwaite

	Fix 10.11.6 support (aka -nometalv2): the stencil view workaround necessitates a mid-render blit and the way things were setup resulted in the HasValidRenderTargets assert firing. Refactored the code to separate the concept or valid render-states in the cache from active render-states in the render-pass. Now it works as intended and will be needed for 4.15.

Change 3236850 on 2016/12/15 by Mark.Satterthwaite

	Make changing the Metal Shader Version project setting prompt the user to restart for the changes to take effect.
	#jira UE-39801

Change 3237002 on 2016/12/15 by Benjamin.Hyder

	submitting updated TM-Shadermodels map

Change 3237312 on 2016/12/15 by Rolando.Caloca

	DR - Change more macros to lambdas

Change 3237394 on 2016/12/15 by Mark.Satterthwaite

	Add Metal-specific permutations of TBasePassHS - they affect the C++ definition on all platforms but are only cached or used on Metal - because the way we compile the combined VS+HS tessellation stage requires that the combined VS + HS HLSL code references the same resources, otherwise we get incorrect resouce bindings and subsequently fail to render properly. Long-term the Metal tessellation code will need to be refactored so that the vertex shader stage is emitted as a separate shader from the hull shader stage as this but will keep cropping back up and continue to complicate the engine.
	#jira UE-39799

Change 3237490 on 2016/12/15 by Daniel.Wright

	Fixed ULandscapeComponent::GetUsedMaterials

Change 3237597 on 2016/12/15 by Ben.Woodhouse

	Disable timestamp queries on pre-Maxwell nvidia hardware. Local testing suggests that this is the major cause of instability in the UE4.14 release.

	It's possible that we could be more targeted by only excluding Fermi and older hardware, but identifying fermi hardware by device ID is difficult in practice, since the range overlaps with Kepler.

Change 3237654 on 2016/12/15 by Daniel.Wright

Change 3238496 on 2016/12/16 by Marc.Olano

	Tone mapping fix for OR-31752, cherry picked from Orion 3208273

	Assumption that green is approximates luminance fails on red/blue HDR content, resulting in ugly black artifacts. Go back to luminance.

Change 3238520 on 2016/12/16 by Rolando.Caloca

Change 3240163 on 2016/12/19 by Daniel.Wright

	Distance field self shadowing controls for hiding world position offset self-shadow artifacts
	* Removed static mesh build settings DistanceFieldBias, which shrunk the distance field, breaking AO and shadows
	* Added DistanceFieldSelfShadowBias, which prevents occlusion close to the surface only, maintaining shadows on the ground and AO on the ground

Change 3240271 on 2016/12/19 by Daniel.Wright

	Use 16 bit indices for distance field objects culled to tiles, when 16 bit will be enough.  Saves 10mb of tile culling buffers.

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

Change 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

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

	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

	#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

	- 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

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)

	#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

	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)

	#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.

Change 3228680 on 2016/12/09 by Gil.Gribb

	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

Change 3229013 on 2016/12/09 by Mark.Satterthwaite

	Further tidy up in SSkeletonTreeView as suggested by Nick.A.

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.

	#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.

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

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

	Support for ReflectionEnvironment and light type show flags with ForwardShading

Change 3149085 on 2016/10/03 by Daniel.Wright

	Support for ReflectionEnvironment show flag in base pass reflections without any shader overhead

Change 3162206 on 2016/10/13 by Chris.Bunner

	Merging Dev-MaterialLayers to Dev-Rendering, CL 3161593:
	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

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

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

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

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

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

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

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

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

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

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

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

	#jira FORT-31616
	#code_review keith.judge

Change 3207541 on 2016/11/22 by Ben.Woodhouse

	Cherry picked from //fortnite/Main@3207422
	* Fix UpdateTexture3D to create a staging texture of the region to update rather than the whole texture. This prevents distance fields crashing during update (allocating 18GB per frame in some cases)
	* Put UpdateTexture2D DMA support onto a cvar, disabled by default (corruption issues reported by licensees, plus not sure it's actually faster - could be slower due to reduced bandwidth; issues reported by licensees)
	* Fix UpdateTexture2D to only create a staging texture of the region to update, saving memory
	#jira UE-38609

Change 3207654 on 2016/11/22 by Chris.Bunner

	Don't flag 16-bit PNG/JPG textures as sRGB on import.

	Unified IsResultMA detection across switch nodes.

Change 3208860 on 2016/11/23 by Rolando.Caloca

	DR - vk - Fix some format issues

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

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

Change 3209305 on 2016/11/23 by Guillaume.Abadie

	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.

	#jira UE-35878

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

	Shadow stencil optimisation with cvar (enabled by default)

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

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

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

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

	Fix for ensure fail when initializing point light shadowmaps.

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

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

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

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

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

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

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

	- Disable framebuffer recycling as its causing a hang

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

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

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

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

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

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

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

The order of initialisation is different per-platform:

	On iOS/tvOS: Order is explicit: Metal MRT > Metal ES 3.1 > OpenGL ES 2

	Renamed texture streaming viewmodes:
	MeshTexCoordSizeAccuracy -> MeshUVDensityAccuracy

Renamed the heavy weight members on this struct to Compute*. Methods that modify The ViewMatrices have been renamed to Hack* to discurage their use in the future until a better solution for those problems is found. The ViewMatrix modification is especially misleading because it only changes the State of the ViewMatrices to read their Position from the Material Editior as if coming from the Lightsource (mainly for manual bilboards) as well as doing someting similar to generate CPU bilboards for shadows.
