32bb8acd0b Support virtual textures on mobile platforms. Requires Vulkan, OpenGL ES3.1 + SRV, iPhone8 and up.
Disabled by default, set r.Mobile.VirtualTextures=1 to enable
known issues: RVT compression is not implementted, Android OpenGL will have R and G channels swapped for uncompressed streaming VT, no sRGB support

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

Change 4073167 by Krzysztof.Narkowicz

	Added subsurface profile for eye shading model.
	#jira none

Change 4073422 by Krzysztof.Narkowicz

	Added dual specular for subsurface profile shading model.
	#jira none

Change 4075278 by Krzysztof.Narkowicz

	Fixed forward reflection/refraction rendering issues, which caused ShaderModels.Material.Refraction to fail.
	#jira none

Change 4084231 by Krzysztof.Narkowicz

	Dual specular - replace lobe spread with two separate roughness multipliers. Default material roughness is now replaced by an average lobe roughness in order to support non dual specular features.
	#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.

Change 4111285 by Brian.Karis

	Eye shading update.
	Added Iris normal (disabled). Removed wrap. Fixed contact shadows.

Change 4155261 by Krzysztof.Narkowicz

	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).

	#jira none

Change 4225614 by Rolando.Caloca

	DR - Enable depth collision particles on Vulkan mobile

Change 4235489 by Uriel.Doyon

	Removed r.DefaultFeature.PointLightUnits and r.DefaultFeature.SpotLightUnits and replaced them by a single r.DefaultFeature.LightUnits which also controls the units of newly placed rect lights.

	#jira UE-59525

Change 4260154 by Mark.Satterthwaite

	Parallelize the creation of Metal archives and libraries when they are broken up into smaller sub-libraries, this should reduce apparent cook time by going wide across threads on the host of the cooker.

Change 4270594 by Brian.Karis

	Fix for textured rect light L pointing away from plane due to approximate diffuse integration.

Change 4273361 by Daniel.Wright

	Particle Cutouts with 8 verts now always use stochastic approach.  Circle textures with > 234 edges in the convex hull were overflowing the uint64 calculation of the total number of combinations, causing an infinite loop.

Change 4309174 by Mark.Satterthwaite

	Graph device utilization from the driver monitor stats - really helps see how well the GPU is being used.

Change 4310121 by Matt.Collins

	Optmizing RemoveUniformBuffersFromSource. Brings it from ~20% to ~1.5% in my testing.

	#jira none

Change 4312960 by Daniel.Wright

	Fix from Stephen Hill for incorrect light grid culling near the near plane

Change 4314169 by Richard.Wallis

	FShaderCache and associated public structures are now marked as deprecated.  All FShaderCache code hooks removed from MetalRHI, OpenGLDrv and engine Launch/Shutdown logic.

	#jira none

Change 4320760 by Arne.Schober

	DR - Remove SV_Coverage from basepass interpolants when running with Masked in early Depth with ForwardShading as otherwise earlyZ will be disabled (as the PS has to run).
	#jira UE-60992

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).

	#jira UE-61401

Change 4336188 by Rolando.Caloca

	DR - Added -ReduceThreadUsage so programs can use less threads (for SCW )

Change 4337967 by Rolando.Caloca

	DR - Remove unused RHISupportsShaderCompression function

  MAJOR FEATURES & CHANGES

Change 3870267 by Arne.Schober

	DR - SafeRelease SRVs that might be hold by the Vertexfactories (maybe due to indirect use in GlobalResources)
	Note that the VFs are not owners of the data, e.g the underlying Buffers might be released before this and this reference counting should be uneccessary

Change 3872507 by Arne.Schober

	Back out changelist 3870267

Change 3988916 by Marcin.Undak

	Quail/Linux compilation fix #rb none #codereview arciel.rekman

Change 4042277 by Rolando.Caloca

	DR - Clear UBs between PSOs on D3D to help track down not setting resources

Change 4042297 by Arne.Schober

	DR - Fix case where LPV requires SSAO to run but no GBuffer is available in formward mode. In this case we force the behaviour to use the simple AO (as ASyncAO pass)
	#jira UE-42135

Change 4042404 by Jian.Ru

	Fix a race condition when RT is disabled and then re-enabled
	#jira

Change 4042437 by Richard.Wallis

	Mac Localization - Mac now uses FUICommand and NSLOCTEXT to build main menu items.  Don't fetch menu items using name since that could change.  Lookup using ID's.

	Note:
	New CB function binding system in *FStartupApplicationToMacMenuBinder*.  Added to simplify the existing and new CB function binding.

	Update:
	Application menu now also gets an update on runtime langauge changed event.  Other menu's get updated anyway as per runloop updates.

	#jira UE-49526

Change 4042602 by Guillaume.Abadie

	Adds support for alpha channel in DOF.

Change 4042603 by Guillaume.Abadie

	Gates global sampler behind SUPPORTS_INDEPENDENT_SAMPLERS for nicer error messsage on platform that do not support them.

Change 4042671 by Guillaume.Abadie

	Massages DOF's shader code for HLSLCC.

Change 4042772 by Mark.Satterthwaite

	Expose the MTLComputePipelineState's label string.

Change 4043013 by Juan.Canada

	Fixed bounds of skeletal meshes could be inverted (min > max) with negative scaling. That was breaking occlusion tests in some scenes, creating flicking issues.
	#jira UE-49290

Change 4043171 by Rolando.Caloca

	DR - Workaround crash on hlslcc

Change 4043182 by Uriel.Doyon

	Fixed skylight issues when using pre-exposure.
	Improved IndirectIrradiance gbuffer encoding when using pre-exposure.

Change 4043452 by Mark.Satterthwaite

	Extensively refactor the MetalRHI GPU profiling code. There is now a "MetalProfiler Start/Stop/Frames=X" in-game command that will spit out JSON files similar to the platform-agnostic TracingProfiler, but this displays the command-buffer encoding and execution which actually makes sense with Metal where we can't arbitrarily insert requests for time-stamps and breaking command-buffers/encoders is expensive.

Change 4044732 by Richard.Wallis

	Fix for macOs restoring to fullscreen results in render with large black border.  Also tested that is fix doesn't seem to re-introduce UE-51270 (CL 3696161).  There appears to be an edge case that can cause the toogleFullScreen: method to not correctly expand window frame to the full screen size - we end up with a frame size of the previous setting.  Forcing the correct values doesn't fix the issue - the only consistant fix seems to be to re-introduce the - (NSSize)window:(NSWindow *)window willUseFullScreenContentSize:(NSSize)proposedSize delegate method.

	#jira UE-57549

Change 4044741 by Guillaume.Abadie

	#jira

Change 4045923 by Mark.Satterthwaite

	Further insulate private plugin usage within MetalRHI.

Change 4046006 by Mark.Satterthwaite

	Simplify dependency on the private module and hope it now builds properly.

Change 4046612 by Mark.Satterthwaite

	Apple A9 introduced support for baseVertex & baseInstance, earlier GPUs don't support it at all. The code was incorrectly compiling shaders assuming they did at given Metal shader standard versions. Instead we always compile mobile shaders assuming they don't support base index & vertex and for dektop shaders we now need an A9 or better GPU for it to work.

	#jira UE-55234

Change 4047504 by Mark.Satterthwaite

	Supress warnings about the missing module when not available or enabled. Also make it work on all Metal platforms.

Change 4048765 by Uriel.Doyon

	Fixed compilation issue from CL 4048308

Change 4048776 by Guillaume.Abadie

	Fixes a static pixel projection regressions in TAA caused by alpha channel support in DOF.

Change 4049059 by Mark.Satterthwaite

	Thread names in the MetalProfiler output and don't load the private module when selecting a device as it isn't useful anymore.

Change 4050290 by Mark.Satterthwaite

	Sort out the timebase for all the different Metal clocks when profiling - everything is now in microseconds and seems to line up! Need to rework all the other timing code similarly - but not in this commit.

Change 4050822 by Mark.Satterthwaite

	Partial custom counter support - still has bugs.

Change 4051210 by Guillaume.Abadie

	Dumps PermutationID of shader when shader compile worker crashes.

Change 4052611 by Guillaume.Abadie

	Fixes a crashes in light shaft.

Change 4052916 by Mark.Satterthwaite

	Extend the Mac & iOS Frame-Pacer API to proivde the target output time and the intended duration so that the MetalProfiler can record the display V-Blank window.

Change 4053111 by Rolando.Caloca

	DR - hlslcc - RequiresNegateDDY()

Change 4053402 by Mark.Satterthwaite

	Add instrumentation for buffer & texture allocation and shader & pipeline compilation to MetalProfiler. Everything that I personally care to track should now be in place but the implementation details are grim so there's still plenty of room for improvement.

Change 4053454 by Mark.Satterthwaite

	More attempts to allow the builders to compile for Mac in such a fashion that the private module's perfectly innocuous headers don't cause an error.

Change 4053765 by Guillaume.Abadie

	Fixes a failure in DOFGather's ShouldCompilePermutation() caused by R11G11B10 change.

Change 4057220 by Guillaume.Abadie

	Cherry-picks and reworks experimental AO decal from GDC 2017's The Human Race demo.

	AO decal are on purpose not supported with ASync AO, because the proper way location to do that would be right before whenever a pass use it, but is currently challenging to track down considering the screen space AO buffer is used a by a lot of different passes through the scene texture uniform buffer.

	In English this means that when the reference is taken (or it is passed by reference) the pointers could be compared and therefore needed to be allocated.

	Merging //UE4/Partner-MGPU to Dev-Rendering (//UE4/Dev-Rendering) at CL 4047519 :
	- Fixed d3derror when resizing the window in multi-gpu.
	- Fixed d3d12 checks when exiting in multi-gpu.
	- Command context containter can now only be used with a single gpu mask. This cleans up passing the mask everywhere.
	- RenderPass now reuse the current GPUMask instead of assuming the view mask. Decoupling furter more the binding.
	- Removed of IRHIComputeContext::GetContextForGPUMask().
	- Removed GPUMask from QueueRenderThreadCommandListSubmit and QueueCommandListSubmit since it is now a member of FRHICommandListBase.
	- FRHICommandListBase::CopyContext() can not change anymore the GPUMask and the target list must have the same GPUMask as the reference one.
	- Command lists now have a GPU mask set at creation time.
	- Support for immediate command list GPU mask.
	- Using the new SCOPED_GPU_MASK where we previously used a new command list on the stack.
	- Refactored most NodeMask naming to GPUMask, and also "const FRHIGPUMask&" to "FRHIGPUMask".
	- Commandline option "-mgpu" is now replaced by "-MaxGPUCount=" and "-PresentGPU="
	- Multi-gpu modes are now controlled through  -mgpumode={ gpu0, gpu1, broadcast, avr, afr }
	- Defines WITH_SLI and WITH_MGPU now control the path to multi-gpu support in the engine.
	- Variable GNumActiveGPUsForRendering is now split in  GNumAlternateFrameRenderingGroups and GNumExplicitGPUsForRendering.

	Duplicate CL #3871025
	Make Manual Vertex Fetch a property of the shader platform for Metal - only the desktop platforms (METAL SM5/SM5_NoTess/MRT) will use manual vertex fetch. The mobile platforms use vertex descriptors. Prevents problems with cooked versions of games not working properly on Metal due to a mismatch between the runtime's Manual-Vertex-Fetch state versus the state used by the cooker when compiling shaders.

	* added FMalloc Unused stat to LLMFULL to account for memory Binned2 has allocated internally. This can be used to track Binned2 fragmentation over time.
	* renamed Binned stats to FMemory to make it more general
	* added Default tracking to CustomVirtualAlloc and disable it where necessary. This catches the few VirtualAlloc calls that were missed.
	* added AllocType arg to all allocation tracking. This was needed in order to track the FMalloc total, and also to fix the pausing
	* fixed a bug in pausing where alloc/frees were being missed. Now only pauses a specific allocation type.
	* Trackers now maintain totals for each enum tag
	* tracking of Texture and mesh allocation on Windows D3D11 & D3D12

	Merging CL 3659069 from //Fortnite/Main/... to to //ue4/dev-console/...:

	[FORTNITE] [CONSOLE] [+] Improved frame syncing mechanism
	 - Improves input latency by allowing the game thread to sync to the swap chain flip of the previous frame.
	 - Added "r.GTSyncType" CVar to control how the game thread syncs with the rest of the pipe.
	 - r.GTSyncType 2 will sync the game thread with the flip of the swap chain, preventing the pipe from getting too long and causing excess input latency.

	Platforms are required to implement RHIWaitForFlip and RHISignalFlipEvent, and call RHIInitializeFlipTracking on RHI startup.
	A separate thread monitors the progress of frame flips and signals task graph events as they pass their corresponding frame index.
	In r.GTSyncType 2 mode, the game thread is signaled by this flip tracking thread.

	[~] Unified platform specific sync interval CVars into one: rhi.SyncInterval
	 - 1 == 60Hz
	 - 2 == 30Hz
	 - 3 == 20Hz

Change 3726532 by Luke.Thatcher

	[CONSOLE] [~] Enable XGE shader compilation by default.
	 - Also set XGE mode to "force interception". With XGE on by default, we don't want people with an old Incredibuild version using the old system inadvertently.

Change 3726554 by Luke.Thatcher

	[CONSOLE] [+] Improved Scoped Named Events
	 - Added SCOPED_NAMED_EVENT(_FSTRING/_TEXT/_F) macros to allow use of string literals, FString and printf in scoped named event strings.
	 - Replaced explicit use of FPlatformMisc::Begin/EndNamedEvent throughout the engine with macros, so the events can be compiled out.
	 - Fixed performance issues on various platforms with named events. SCOPED_NAMED_EVENT macros were not considering whether the platform uses wide or ansi char strings.

	Duplicate from FN CL 3712515
	CSV profiler GPU and pre-declared stat support
	- refactor the GPU profiler so it's no longer dependent on the stats system and can work in Test builds
	- add support for pre-declared CSV stats, using FNames (these are required for GPU stats)
	- add DECLARE_GPU_STAT macro which handles STATS and CsvProfiler declarations
	Note: still a few issues to resolve with GPU stats: these randomly go to 0 at times during a replay on XB1, the GPU total is lower than the stat unit number, and the unaccounted stat is too large due to missing stats

Change 3813513 by Ben.Woodhouse

	CSV profiler refactor+ bug fix
	- Move the CSV profiler to core, so we can use it in modules other than engine
	- Profiler no longer enqueues RT commands - this is handled by a new core delegate type
	- Make begin/end requests more robust, enqueued via a command queue and processed in order
	- Defer end capture requests by a frame. This ensures stats on threads other than the gamethread (e.g. renderthread etc) are complete, so the last frame is not truncated
	- Fix long-standing bug with multiple captures where old/stale frames would appear in the first <128 frames of captures
	- Move unit stats and dynamic resolution out of the profiler itself and into the engine. Only frametime is recorded in the profiler now
	- Fix longstanding bug in first frame renderthread time in the engine

Change 3814039 by Ben.Woodhouse

	More Csvprofiler improvements
	- Event support (via CSV_EVENT macros). These appear in the "EVENTS" column of the CSV and can be used to add context to the stat data
	- Reduced memory overhead for timestamps through bit-packing (now 16 bytes per marker instead of 24), and splitting stats into different types

Change 3814041 by Ben.Woodhouse

	Integrate as edit CL 3796390 from Fortnite/Main:

	Fix CsvProfiler not compiling in shipping for now

Change 3814229 by Ben.Woodhouse

	Integrate + refactor of CL 3792591 to reduce complexity and fix bugs

	Original changelist description:
	CSV profiler improvements:
	- The CSV profiler is now always compiled in on the server
	- The CSV profiler can now handle both int32 and float stats
	- In BeginCapture, the function can take additional arguments for some customization of filenames

	Fixes to the above:
	 - Remove FCustomValue class
		- Fixes bug where all timestamp values from CSV_SCOPED_STATs were garbage (due to issues resulting from FCustomValue type ambiguity when adding values together)
		- FCsvCustomStat now just uses simple union + bitfield flag to reduce size and complexity (4 bytes instead of 8 per value)
		- FCsvColumn class modified to use doubles, which can represent both ints and floats without loss of precision - this class is not memory or time critical
	 - Replace multiple overrides used by the server for filenameprefix/folder/postfix etc with a single FilenameOverride

Change 3814242 by Ben.Woodhouse

	Disable CSV unit stats on the dedicated server

Change 3817339 by Ben.Woodhouse

	Duplicate from 3816641: CSV profiler improvements
	- Added a low-pri processing thread to compress raw timing data into a much more efficient format
	   - Reduces memory usage for 15 minute 30k frame capture with GPU stats enabled from 110MB to 3.4MB
	   - Processing time : 0.1ms per frame
	- Improved name handling for char literal stats. We now use the string as the ID rather than the pointer so multiple stat uses of the same name string apply only to  a single stat
	- Reworked thread data access to eliminate locking for anything time-critical. Frame boundaries now handled via a lock-free helper class
	-  Fixed bug with queue implementation where 1 in 128 reads would duplicate the last block of stat data
	-  Reduced #include dependencies for CSVProfiler.h
	-  Removed AccumulateMax because it doesn't work, and implementing properly would add a lot of complexity
	-  Added a simple test harness

Change 3817582 by Ben.Woodhouse

	Fix android compile warning

Change 3823242 by Ben.Woodhouse

	Integrate as edit from Fortnite/Main 3820067:

	Fix threading issue with D3D12 pipeline state caches for windows. This was caused by the usage of FRwScopeLock::RaiseLockToWrite. A pointer read before RaiseLockToWrite was called was invalidated because RaiseLockToWrite has to release the read lock before acquiring the write lock.

	Rename FRwScopeLock::RaiseLockToWrite to ReleaseReadOnlyLockAndAcquireWriteLock_USE_WITH_CAUTION to make it more explicit what's happening. As the comment says:

		// This function should be used with caution.
		// It releases the read lock _before_ acquiring a new write lock. This is not an atomic operation and the caller should
		// not treat it as such.
		// E.g. Pointers read from protected data structures prior to this call may be invalid after the function is called.

Change 3823840 by Ben.Woodhouse

	Edigrate from 3823816
	Fix an issue where the csvprofile console commands would sometimes result in an empty CSV. The root cause was GFrameNumber incrementing between the console command being read and FCSVProfiler::EndFrame(). We now use our own frame counter which is updated in EndFrame, so this can't happen

	Also fix an issue where calling csvprofile stop twice would cause all further commands to be ignored.

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

	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.

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.

	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

	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 3541347 by Yujiang.Wang

	Fix wrong ViewFlags being set between objects when rendering shadow depth maps

	Fixed shadow occlusion culling broken by shadowmap caching change.  FProjectedShadowKey is now computed correctly for whole scene shadows and SDCM_StaticPrimitivesOnly shadowmaps will fall back to the query for a SDCM_MovablePrimitivesOnly, since the static primitives shadowmap's query is not issued every frame.

	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.

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....

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

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

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

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

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

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

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

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

	#jira UE-35878

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

	Shadow stencil optimisation with cvar (enabled by default)

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

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

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

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

	DR - [UE-34481] - Extract all the State which is necessary to execute the DebugTextDrawingDelegate from the SceneProxy into its own Helpers to be drawn to the canvas later on.

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

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

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

	Improve vector noise tooltips & documentation

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

	Fix for ensure fail when initializing point light shadowmaps.

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

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

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

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

	#jira UE-32724

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

	#jira UE-35937

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

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

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.

	Duplicate CL #3140166
	Fix the video playback in Fortnite - bind our shader resource texture as the render-target texture as for some reason the playback code expects it there, even though we could never provide one.
	#jira FORT-30551

Change 3140584 on 2016/09/26 by Mark.Satterthwaite

	Duplicate CL #3140131:

Change 3140594 on 2016/09/26 by Zabir.Hoque

	Fix benchmark shaders register bindings. TEXCOORD0 was bound to register 1 in VS and then register 0 in PS. DX12 treats this a PSO creation failuer unlike DX11 this was an error.

Change 3140601 on 2016/09/26 by Marcus.Wassmer

	New 'Cinematic' Scalability level.  Remove unused 'new' motionblur CVAR

Change 3140602 on 2016/09/26 by Zabir.Hoque

	CreateTexture3D on XB1 DX11 was leaking ESRAM by reserving it but not allocating to it.

Change 3141941 on 2016/09/27 by Olaf.Piesche

	Speculative fix for UE-34815; have yet to repro this but there's really only so many things it could be. I currently don't see how the sim resources could go away after queueing, so I'm replacing the check with an ensure and null checking the resource pointer.

Change 3142035 on 2016/09/27 by Olaf.Piesche

	Fix compiler error from silly leftover bit of code.

Change 3142065 on 2016/09/27 by Benjamin.Hyder

	Updating Lighting Scenario map

Change 3142262 on 2016/09/27 by Mark.Satterthwaite

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

	DR - Proper support for int defines

Change 3142519 on 2016/09/27 by Arne.Schober

	DR - [UE-33438] - Added a Project Setting to enable Skincache Shader Permuations. The Default value for the Skincache mode was changed to enabled. The reasoning behind this was that it will be auto disabled when Skincache Shaders are disabled, and runtime toggle is a debuging feature that mainly programmers are dealing with. The Recompute Tangents option in the Skinned Mesh is now automatically grayed out when no Skincache Shader Permuations are available.

Change 3142537 on 2016/09/27 by Daniel.Wright

	Fixed r.ScreenPercentage with MSAA - a scissor rect was being setup during the resolve and not reset

Change 3142712 on 2016/09/27 by Daniel.Wright

	Separate category for ParticleCutout properties

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

	Added per static mesh and per skeletal mesh UV density data. The data is now saved and available in cooked builds.
	The density are computed by the engine but can be overridden by the user in the material tabs.

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

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

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

	Improved UV density computation and viewmode.

	LightmapUVDensity is now computed separately from UVChannel Density.

	Fixed texture streaming for instanced static mesh component and derived types.

	DumpUnbuiltLightIteractions after lighting build for debugging

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

	DR - Refactoring of the ViewMatrices. Moved the Derived Matrices into the FViewMatrix struct. Made all members private do emphasize the static constness of that struct after creation. Renamed the heavy weight members on this struct to Compute*. Methods that modify The ViewMatrices have been renamed to Hack* to discurage their use in the future until a better solution for those problems is found. The ViewMatrix modification is especially misleading because it only changes the State of the ViewMatrices to read their Position from the Material Editior as if coming from the Lightsource (mainly for manual bilboards) as well as doing someting similar to generate CPU bilboards for shadows.

Change 3046088 on 2016/07/12 by Ben.Woodhouse

	Live GPU stats
	A non-hierarchical realtime high level GPU profiler with support for cumulative stat recording.
	Stats are added with SCOPED_GPU_STAT macros, e.g. SCOPED_GPU_STAT(RHICmdList, Stat_GPU_Distortion)
	The bulk of the files in this change are simply instrumentation for the renderer. The core changes are in SceneUtils.cpp/h and D3D11Query.cpp (this is the XB1/DX11X implementation of timestamp RHI queries, which was missing)
	Note: this is currently disabled by default. Enable with the cvar r.gpustatsenabled
	Tested on PC, XB1, PS4

	UE-23925
	Clamping noise tessellation for beams at a high but sensible value; also making sure during beam index buffer building that we never get over 2^16 indices; this is a bit hokey, but there are so many variables that can influence triangle/index count, that this is the only way to be sure (short of nuking the entire site from orbit).
