Change 3310176 on 2017/02/17 by Chris.Bunner
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
Prevent SpeedTree node compiling for skeletal meshes (not supported as uses more UV sets than available).

Preparing TM_Shadermodels map for automation
Change 3328222 on 2017/03/01 by Chris.Bunner
Prevent decals from drawing in separate translucency pass. Whilst user control and material relevance were already removed, if the flag was checked before being disabled (by swapping to decal domain) this was still being read in the render loop, now explicitly ignores decals.

[Copy] Changing movable skylight properties no longer affects static draw lists
Change 3333693 on 2017/03/06 by Daniel.Wright
[Copy] Added 'r.AOListMeshDistanceFields' which dumps out mesh distance fields sorted by memory size, useful for directing content optimizations
Change 3333705 on 2017/03/06 by Daniel.Wright
[Copy] Mesh distance fields are now 8 bit fixed point by default, but can be changed back to 16 bit floating piont with a project setting.
* 8 bit uses half memory but introduces error for thin surfaces or large meshes.
Change 3333721 on 2017/03/06 by David.Hill
DecalProxy:
Copy float FadeScreenSize to FDeferredDecalProxy for use in the render thread. This avoids pointer chasing to the UDecalComponent (game thread component).
Change 3333772 on 2017/03/06 by Daniel.Wright
[Copy] Scene motion blur data is only updated for the main renderer frames. Fixes scene captures and planar reflections breaking object motion blur.
Change 3333790 on 2017/03/06 by Daniel.Wright
[Copy] Mesh distance field generation uses Embree, for a 2.5x speedup

Change 3333822 on 2017/03/06 by Daniel.Wright
[Copy] Moved mesh distance field code into MeshDistanceFieldUtilities.cpp
* Moved FMeshUtilities to its own header so the 8k line MeshUtilites.cpp file can be further split up

Non-editor compile fix
Change 3333836 on 2017/03/06 by Daniel.Wright
[Copy] Workaround for gobal distance field volume textures being bloated by 4x on PS4 due to the recommended tiling modes. They now use a 2d tiling mode which avoids the bloat, saving 96Mb.
Change 3333843 on 2017/03/06 by Daniel.Wright
[Copy] Added OcclusionExponent to skylight component
* Useful for brightening up indoors without losing contact shadows as MinOcclusion does

Change 3333857 on 2017/03/06 by Daniel.Wright
[Copy] Clear light attenuation for local lights with a quad covering their screen extents
* Clearing the entire light attenuation buffer costs .1ms on PS4. This optimization lowers the minimum cost of a shadow casting light from .15ms -> .03ms.
* Shadowed lights in Fortnite with 25 lights 3.7ms -> 1.42ms on PS4
Change 3333860 on 2017/03/06 by Daniel.Wright
[Copy] Flush deferred deletes when reallocating distance field atlas to reduce peak memory
Change 3333861 on 2017/03/06 by Daniel.Wright
[Copy] Disable all distance field features on Intel cards as HD 4000 hangs in the RHICreateTexture3D call to allocate the large atlas
Change 3333869 on 2017/03/06 by Daniel.Wright
[Copy] Volumetric Fog using a volume texture mapped to the camera frustum
* Volumetric fog can be enabled on an Exponential Height Fog component with additional controls
* Lights have a VolumetricScatteringIntensity
* New cvars r.VolumetricFog, r.VolumetricFog.GridPixelSize, r.VolumetricFog.GridSizeZ, r.VolumetricFog.DepthDistributionScale
* Lighting features supported:
* Directional light with CSM and a light function
* Point / spot lights without shadows / light functions / IES profiles
* Skylight with occlusion from distance fields
* Analytical height fog covers the view range past where the volumetric fog ends
* Temporal reprojection is used on the volumetric fog scattering and extinction to achieve stability
* Translucency integrates properly into volumetric fog
* Height fog StartDistance is not supported by volumetric fog and should be set to 0.
Change 3333894 on 2017/03/06 by Daniel.Wright
[Copy] Initialize GDummyVolumetricFogGlobalDataUniformBuffer outside of parallel rendering
Change 3333902 on 2017/03/06 by Daniel.Wright

[Copy] Fixed volumetric fog trying to render light functions for a point light
Change 3333908 on 2017/03/06 by Daniel.Wright
[Copy] Volumetric materials
* Added new material domain Volume, which can output Scattering, Absorption and Emissive. All properties are in world space densities.
* Particle systems using the Volume domain are voxelized based on their ParticlePosition and ParticleRadius
* Volumetric fog integration is now energy conservative - scattering is integrated against transmission over the depth of each slice.
* Added bOverrideLightColorsWithFogInscatteringColors to exponential height fog, which can be enabled to make Volumetric Fog match Height fog more closely
Change 3334134 on 2017/03/06 by Daniel.Wright
[Copy from Michael Trepka] Added Embree 2.14.0 and changed MeshUtilities to use it as this solves issues with Embree leaking TLS keys. UnrealLightmass is still using older Embree 2.7.0 until we can find time to properly test it with the new version. Also, invalidated distance field DDC to force it to rebuild with updated Embree.

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

Duplicated from Fortnite CL 3243458:
D3D12 memory optimization - The d3d12 buddy suballocator is very wasteful for allocations above 4KB, but the vast majority of allocations are smaller . In the default buffer allocator this was causing 149MB of waste in 340MB of allocations. Moving the max allocation size threshold down to 4KB from 512KB saved 100MB of memory wastage memory.
On PC, buffers are 64KB aligned, so we need the threshold to be higher to avoid additional wastage.
Add PIX memory tracking instrumentation for buddy allocators so we can track the memory properly in PIX

Duplicated from Fortnite 3243496
memory optimisation: use NULL-terminated ansi strings instead of unicode FStrings for symbols, saving 118MB. Previously the strings were loaded from disk as ansi and then converted to FStrings (slowly), before finally being converted them back to ansi strings before being used. In addition to reducing memory overhead, this change reduces complexity and improves startup time.

The bound defrag is now done outside of the async work logic.
Change 3252866 on 2017/01/10 by Mark.Satterthwaite
Fix Metal shader pipeline hash collisions caused by deferring MTLFunction construction until PrepareToDraw so that we may use Function-Constants to specialise the shader source without generating additional permutations. This is required to generate proper tessellation shaders which are specialised against the index-buffer usage & type (none, uint16, uint32). While we're here amend the hash functions to make better use of the existing hash functions to improve the distribution and hopefully reduce the possibility of collisions in future.

DR - PSO stats
Change 3255958 on 2017/01/12 by Mark.Satterthwaite
Reimplement RQT_AbsoluteTime for Metal - pretty sure I did this before, but somehow it got lost. When a RQT_AbsoluteTime is inserted into the command-stream, insert a command-buffer completion handler to record the time of completion & submit the command-buffer immediately. This breaks command-buffers so is noticeably slower and if inserted in a pass that can't be restarted will fail but is currently the only option available. This is sufficient to support the GPUBenchmark used by Scalability. To make this more efficient I've refactored the FMetalCommandBufferFence implementation so that we use a single shared-ptr object containing the command-buffer and a dispatch semaphore, rather than allocating one for each query. The semaphore allows for timed-waits where previously we'd block until completion, unlike the other APIs that report failure after a fixed interval (2s for RQT_AbsoluteTime, otherwise 0.5s). Sadly not all drivers support this abuse of the Metal API, so replace the GL-based workaround for not having time queries with one that just guesses based on RHI device details. Radars will be filed.

DFAO optimizations
* Changed the culling algorithm to produce a list of intersecting screen tiles for each object, instead of the other way around. Each tile / object intersection gets its own cone tracing thread group so wavefronts are much smaller and scheduled better. 3.63ms -> 3.48ms (.15ms)
* Replace slow instructions in inner loop with fast approximations (exp2 -> sqr + 1, rcpFast, lengthFast) 3.25ms -> 3.09ms (.16ms)
* Moved transform from world to local space out of the inner loop (sample position constructed from local space position + direction) 3.09ms -> 3.04ms
* Compute shader for ClearUAV 3.04ms -> 2.62ms (.42ms)

Change 3260594 on 2017/01/17 by Daniel.Wright
Added a new global distance field (4x 128^3 clipmaps) which caches mostly static primitives (Mobility set to Static or Stationary)
* The full global distance field inherits from the mostly static cache, so when a Movable primitive is modified, only other movable primitives in the vicinity need to be re-composited into the global distance field
* Global distance field update cost with one large rotating object went from 2.5ms -> .2ms on 970GTX and 4.6ms -> .3ms. Worst case full volume update is mostly the same.
* Adds 12Mb for the new volume textures

Integrate latest changes from MS-DX12 CLs 3231395-3262526
- Added WinPixEventRuntime.tps
- Includes PIX support, various optimizations (saved 1.3ms in testbed scene)
CL 3262343:
Fix depth testing on translucency not working correctly after cl 3231395. This change reapplies the D3D12RHI changes from CL 3231395 because those changes were lost when integrating from //Dev-Rendering/ but also includes the depth fixes:
- Fix depth state not being in DEPTH_READ for use as depth read. The issue was HasDepthBits and HasStencilBits wern't intended for SRV formats and always returned false in the SRV case.
CL 3231395:
Update D3D12 RHI:
- Fix deferred MSAA path in RHI
- Add Pix3.h support
- Cleanup SetName usage and remove it from shipping builds.
- Fix fence reuse bug. We were signaling MAX UINT (-1) and then waiting for 0, which was always signaled. This change also removes the fence value reset code, there is no need to reset a fence to a previous value.
- Use FPlatformAtomics::InterlockedIncrement instead of InterlockedIncrement64
- Use InterlockedIncrement() instead of _InterlockedIncrement() and use the FPlatformAtomics:: version.
- Fix possible readback heap being evicted while in use. GetQueryData happens on the render thread and isn't tied to a command list so we should always have readback heaps resident.
Change 3264251 on 2017/01/19 by Mark.Satterthwaite
Modify some asserts in MetalRHI - technically using a store-action of ENoAction on Stencil buffers should make it invalid to restart a render-pass but on Mac it will work because ENoAction won't invalidate anything written. In future we need to use deferred store-actions in Metal so that we can "restart" passes while enforcing correct Load/Store actions.

ESRAM support stage 1:
Implemented noncontiguous ESRAM page allocator replacing XgMemoryLayout API. The allocator allocates non-contiguous ranges of pages and maps them onto a contiguous virtual address range.
Unlike the previous implementation, this allocator frees pages for reuse when resources are destroyed
Note: issues with deferred deallocation may prevent reuse in many cases - that will be addressed in the next stage
Support for the old allocator is still available (for now) via the define NEW_ESRAM_ALLOCATOR

- Eliminate redundant state changes in MetalRHI in the state cache.

- 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.

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.

XB1/Fast semantics:
Add missing L1/L2 cache flush on transition to readable (or RW). The missing cache flush was causing indeterminism when reading from a texture shortly after writing to it as a render target.
This fixes bloom and diffuse irradiance issues
The bug has been there for a while, but CL 3227787 (drawclear early out) caused it to manifest
#jira UE-39727

MAJOR FEATURES + CHANGES
==========================
Change 3148067 on 2016/10/01 by Daniel.Wright

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.

* 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

Change 3209265 on 2016/11/23 by Arne.Schober
DR - originally unshelved from 3153924 - Made Depth and Velocity Rendering Passes to use PSO only RHI interface,
We are now passing down two structs that collect all the necessary information for the drawing policies to construct a PSO object.
One during construction of the Policy, which contains information abouyt the CullMode, FillMode and PrimType.
And another during rendering that passes infomation like BlendState and DepthStencilState down to the low levelrenderer into SetSharedState.
Performance of the static drawlist ist slightly slower (less than 0.1ms on Consoles) due to some addtional branches and copies. The branches in the FDrawingPolicyRenderState will go away as soon as everything is converted to use the PSO interface.
Performace of the GPU is slightly better due to less context rolls (mainly CullMode sorts in differently now)

Changes from UE4-DX12:
*** CL 3183818 ***
Update D3D12 RHI to 4.14:
- Merged changes from Epic up until 10/20/16
- Fixed an issue where command allocators where resetting too early. I changed to aggressive command list batching by default now that more SubmitCommandListHint calls exist in the upper engine, we don't need to worry about starving the GPU. Fewer ExecuteCommandLists calls means better performance and fewer Signals() so this change provides a GPU perf win.
I had to fix an issue with aggressive batching where we would sometimes hold on to a command list long enough (in the pending list) but hadn't executed it yet. The command allocator was being put back in the queue of allocators during ReleaseCommandAllocator() without a syncpoint set and was thus being reset too early. I added a simple counter to the command allocator so it could track how many command lists were using it. It doesn't need to be thread safe since only one thread uses a command allocator at a time.
I also added some stats around the # command lists and # command allocators since it would be possible to leak command allocators now if it's pending command list count isn't decremented correctly. In that case we'd keep creating new command allocators and eventually run out of memory.
-Remove clear during allocate in the FD3D12FastConstantAllocator and FD3D12FastAllocator. The supplied resource locations are assumed to be new and thus don't need to be cleared.
-Cleanup D3D12RHI stats. There were some unused stats as well as some missing ones.
-Mark shader resource table uniform buffers as dirty only when the shader changes. Cleanup SetComputeShader calls and Dispatch calls to not set/unset the CS for each Dispatch.
-Remove unused Check SRV resolved code that epic added to the D3D11 RHI and was brought over. We dont need it and we won't use this.
-Remove "always on" cycle counters for high frequency RHI methods like RHISetShaderTexture. These should use the engine's stat macros as they are removed on TEST + SHIPPING builds. On Xbox a significant amount of CPU time is spent in things like QueryPerformanceCounter even when STATS aren't enabled. Currently 1% of an entire capture on XBOX is spent inside this call.
I improved and cleaned up high freqency call stacks like:
- RHISetShaderTexture
- RHISetShaderResourceViewParameter
- RHISetShaderParameter
- RHISetUAVParameter
In general I moved to use templated functions, removed unused parameters, unnecessary copies, etc.
-Change D3D12 PIX profiling enable/disable to match Xbox and handle logic in the UEBuildWindows.cs for UBT. Also add a static assert to inform the developer when PIX profiling is requested but the engine is compiling out draw events.
-Resources should be associated with the rendering thread's frame that it's currently recording command lists for and they shouldnt be cleaned up until those command lists have been translated to D3D12 command lists on the RHI thread AND completed executing on the GPU. This was confirmed to resolve an issue where CBV resources were being released too early.
This work involved a couple changes:
1) Move the "frame" fence to be incremented on the rendering thread (during RHIAdvanceFrameForGetViewportBackBuffer()) so that resources that are deleted from the rendering thread are assosicated with the correct frame count
2) Queue up a command from the rendering thread to signal the "frame" fence. It needs to be queued to ensure that it's signaled at the correct time on the RHI thread (after that frame's command lists have been executed).
-Disable GRHIRequiresEarlyBackBufferRenderTarget. Metal/Vulkan/Xbox11.x already do this. This is used by the Slate renderer during BeginRenderFrame and avoids a SetRenderTargets call.
-Enable GRHISupportsMSAADepthSampleAccess (used in the Editor). This was enabled for D3D11 on SM5, but not for D3D12.
-Delay load D3D12.dll and add root signature 1.1 support.
-Add explicit flush calls to improve resource barrier batching instead of implict flushes inside FConditionalScopeResourceBarrier and FScopeResourceBarrier. Also update those classes with const members.
*** CL 3183824 ***
Fix the D3D12 RHI after integrating UE 4.14 updates:
- Fixed a bug where we would try to get the PSO of a nullptr in SetPipelineState if we needed to reset the current PSO on the cmd list.
- Fixed a spelling error
- Removed the need for bForceState, we use dirty bits now
*** CL 3183830 ***
- GetDebugFlags RHI extension, needed by XB1 movie player.
- Only query memory info if stats are enabled
- Add support for the engine's new RHISubmitCommandsAndFlushGPU function
- Update CommitPendingPipelineState to be Graphics/Compute specific and avoid the need for a IsCompute parameter.
*** CL 3183837 ***
Made PipelineState caches contain pointers to FD3D12PipelineState objects to avoid issues with using pointers to after Find/Add to the maps. TMap indicates that the pointer to the value associated with a key "is only valid until the next change to any key in the map." The lifetime of the PSO pointers is managed by the low level caches (graphics and compute). Added stat for the number of Pipeline State Objects.
*** CL 3183931 ***
Update Windows D3D12 headers and libs to RS1 release bits (10.0.14393.0)
*** CL 3183978 ***
Update UBT Windows build settings:
- Change D3D12 PIX profiling enable/disable to match Xbox and handle logic in the UEBuildWindows.cs for UBT. Also add a static assert to inform the developer when PIX profiling is requested but the engine is compiling out draw events.
-Delay load D3D12.dll and add root signature 1.1 support.
*** CL 3184132 ***
Fix Xbox PSO cache code where it could leak PSOs. Related to change 3183837.
*** Changelist 3211714 ***
Update D3D12 RHI with fixes:
- Check if we can reserve slots in GatherUniqueSamplerTables
- DirtyState more often in StateCache
- Remove InternalSetSamplerState. The alternate function isn't used.
- Allow MRTClear for arrays with holes in them
- Fix uninitialized descriptors. This was causing a GPU hang on Xbox. We need to set dirty bits for resources bound to slots outside of the current descriptor table's range
- Cleanup SetDescriptorHeap code. Move setting descriptor heap logic to the descriptor cache since it also owns things like the sampler maps. Added members to the descriptor cache to track the last heaps that were set on the command list to avoid dirtying bit unnecessarily.
- Resource transitions: go through Common between queues (3D <--> Compute)
- Fix initial state for placed resources.
- Merging epic

Change 3209340 on 2016/11/23 by Ben.Marsh
Convert UE4 codebase to an "include what you use" model - where every header just includes the dependencies it needs, rather than every source file including large monolithic headers like Engine.h and UnrealEd.h.
Measured full rebuild times around 2x faster using XGE on Windows, and improvements of 25% or more for incremental builds and full rebuilds on most other platforms.
* Every header now includes everything it needs to compile.
* There's a CoreMinimal.h header that gets you a set of ubiquitous types from Core (eg. FString, FName, TArray, FVector, etc...). Most headers now include this first.
* There's a CoreTypes.h header that sets up primitive UE4 types and build macros (int32, PLATFORM_WIN64, etc...). All headers in Core include this first, as does CoreMinimal.h.
* Every .cpp file includes its matching .h file first.
* This helps validate that each header is including everything it needs to compile.
* No engine code includes a monolithic header such as Engine.h or UnrealEd.h any more.
* You will get a warning if you try to include one of these from the engine. They still exist for compatibility with game projects and do not produce warnings when included there.
* There have only been minor changes to our internal games down to accommodate these changes. The intent is for this to be as seamless as possible.
* No engine code explicitly includes a precompiled header any more.
* We still use PCHs, but they're force-included on the compiler command line by UnrealBuildTool instead. This lets us tune what they contain without breaking any existing include dependencies.
* PCHs are generated by a tool to get a statistical amount of coverage for the source files using it, and I've seeded the new shared PCHs to contain any header included by > 15% of source files.
Tool used to generate this transform is at Engine\Source\Programs\IncludeTool.

Change 3170391 on 2016/10/21 by Ben.Woodhouse
Remove the wait on end of frame ensure, because we can't rely on all the the underlying codepaths to never miss a call to flush RHI resources. The consequences of missing a flush on a given frame are not serious now, since we enforce the synchronisation with a fence, preventing the rendering thread from getting too far ahead. We will simply accumulate resources for an additional frame when this happens.

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)

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))).

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.

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.

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.

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.

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.

Improved skin postprocess - support for full resolution, with diffuse/spec lighting combined into single RGBA (sharing chroma)
Full res lighting gives less temporal AA flickering, sharper diffuse and specular lighting in the surface (since this is now at full resolution), faster postprocessing if using a 64-bit rendertarget (on NV 980Ti).
Checkerboard rendering is controlled via the r.sss.checkerboard cvar. - 0 is off/full res, 1 is checkerboard, 2 is automatic based on scenecolor (non-checkerboard requires 64bit or more rendertarget w/separate alpha)
Tested/profiled on PC, PS4

Downsampled separate translucency uses a separate view uniform buffer with correct buffer sizes
* Fixes WorldPosition in downsampled translucency
* View uniform buffer parameters are now cached on the view, to allow recreating the uniform buffer without having to rebuild the entire struct. Currently used by global distance field, downsampled separate translucency.
* Fixed the downsampled translucency depth buffer being full res used together with a smaller color target, now they are both the downsampled res

Change 3055904 on 2016/07/19 by Daniel.Wright
Reflection environment normalization improvements
* Indirect specular from reflection captures is now mixed with indirect diffuse from lightmaps based on roughness, such that a mirror surface will have no mixing. Reflection captures now match other reflection methods like SSR and planar reflections much more closely.
* When a stationary skylight is present, Reflection captures are now normalized as if the initial skylight will always be present, giving consistent results with static skylight reflections. The skylight and reflection captures with sky removed used to be normalized separately, compacting the relative brightness between the sky and scene.
* Added r.ReflectionEnvironmentLightmapMixing for debugging lightmap mixing issues. This toggle was previously not possible due to prenormalizing the capture data.
* The standard deferred reflection path (r.DoTiledReflections 0) can no longer match the results of the compute path or base pass reflections, as it would require MRT to accumulate the average brightness
* Removed unused r.DiffuseFromCaptures
* Cost of reflection environment on PS4 increased from 1.52ms -> 1.75ms with this change, but decreased back to 1.58ms by reducing tile size to 8x8

MSAA support for the forward renderer
* AntiAliasing method is chosen in Rendering project settings, DefaultSettings category
* Deferred passes like shadow projection, fogging and decals are only computed per-pixel and can introduce aliasing
* Added Rendering project setting VertexFoggingForOpaque, which makes height fog cheaper and work properly with MSAA
* The AntiAliasing method in PostProcessSettings has been removed, this may affect existing content
* Added r.MSAACount which defaults to 4
* Integrated wide custom resolve filter from Oculus renderer, controlled by r.WideCustomResolve
* GBuffer targets are no longer allocated when using the forward renderer
* Decal blend modes that write to the GBuffer fall back to SceneColor emissive only
Change 3062666 on 2016/07/23 by Uriel.Doyon

After taking a screenshot using glReadPixels, transfer the data to the target buffer from bottom row up to fix the "upside-down" render that OpenGL does.

Change 3051574 on 2016/07/15 by Jack.Porter
Support for lighting channels on Mobile
- Multiple directional lights are supported in different channels but primitives are only affected by the directional light in the first channel they have set
- CSM shadows from stationary or movable directional lights correctly follow their lighting channels
- No channel limitations for dynamic point lights
Notes:
Removed mobile-specific directional light shadowing fields from View uniform buffer and mobile no longers uses SimpleDirectionalLight.
Separate uniform buffers for mobile directional light are generated for each lighting channel.
CSM culling information is now stored in FViewInfo and not per FVisibleLightViewInfo as the visibility bits are per view.

Change 2731596 on 2015/10/16 by Keith.Judge
Fast Semantics - Add deferred resource deletion queue to make deleted resources be actually deleted a number of frames later so that the GPU is definitely finished with them. Hooked up the temporary SRVs for dynamic VBs as a first step.
Change 2764244 on 2015/11/12 by Keith.Judge
Stop creating/deleting SRVs for dynamic buffers all the time. Instead add a new view when a new buffer is cycled and keep them around until the buffer is dead.

Disable Metal on Mac OS X versions prior to 10.11.4 because their drivers are too buggy and lots of issues users will encounter were fixed in 10.11.4.

Re-enable DistanceFieldAO on Mac Metal, but disable the support for Heightfield composition into the DistanceFieldAO as that currently requires Read+Write texture support which isn't present in Metal yet.

Change 2936706 on 2016/04/07 by Mark.Satterthwaite
Fix implementation of BeginRenderingPrePass to only clear the depth+stencil buffers when it is asked to - this fixes LOD fading in Paragon on Mac when parallel execution is enabled. The parallel contexts were being instructed to clear the pre-pass data which was then fouling up all the subsequent rendering.
Change 2936708 on 2016/04/07 by Mark.Satterthwaite
Extend workaround from 2905206 for UE-27818 to Metal as well as OpenGL - it isn't permissable to have an unbound resource on these APIs as you aren't allowed to make the assumption than an if-branch will protect against null dereference on the GPU.
Change 2936737 on 2016/04/07 by Mark.Satterthwaite
Changes to reduce Metal's peak memory usage when streaming texture data in when loading levels:
- When uploading data to Shared memory Metal textures dispose of the source buffer immediately as it won't be required after the call to replaceRegion.
- Add an optional CVar ("rhi.Metal.MaxOutstandingAsyncTexUploads") and keep a count of outstanding async. texture uploads - really this might be better as a memory count - if teh current outstanding count is greater than the specified CVar wait for all operations to complete before purging the used buffers. By default the CVar is set to 0 which disables the tracking and the game will use all available memory.
Change 2936741 on 2016/04/07 by Mark.Satterthwaite
For Metal don't use a texture-view unless the mip-range or texture format is different - we only create a texture-view if we absolutely have to in order to avoid performance reductions on some vendors. When this happens we'll have to update the SRV to point to the new source texture but that can be handled on bind.
Change 2936753 on 2016/04/07 by Mark.Satterthwaite
Mutex the pipeline cache inside each Metal bound-shader-state - with parallel execution this can be modified from multiple threads.
Change 2936758 on 2016/04/07 by Mark.Satterthwaite
Don't eliminate redundant Metal command-encoders on Intel either - this only seems to work correctly on AMD...
Change 2936762 on 2016/04/07 by Mark.Satterthwaite
Validate that parallel contexts aren't asked to clear render-targets (incl depth/stencil) as this won't work as desired - each context will end up clearing the contents meaning none of the rendering will propagate which is probably not what you intend.
Change 2936765 on 2016/04/07 by Mark.Satterthwaite
Fix alignment of blit-commands between textures & buffers in Metal. Mac Metal has no minimum alignment and allows tightly packed rows, but mobile H/W has a fixed row alignment of 64-bytes for linear texture data.

In MetalRHI move the calls that reset the state-cache and command-encoder to EndFrame and fix the fallout. Hopefully this will eliminate the problem where a draw call fails because a call to SetRenderTargets hasn't been made since the last time the command-buffer was submitted.

PR #2193: Commandlet tweaks: Fixup Redirects and Cook-on-the-fly Server (Contributed by FineRedMist)
Change 2936799 on 2016/04/07 by Mark.Satterthwaite
Automatically enable RHI thread support in Metal if parallel execution is compiled in unless running the Editor which doesn't support it. The RHI thread is only enabled in Metal when parallel execution is available because there's little to no advantages to the RHI thread with Metal unless parallel execution is enabled. Also only enable async compute support when parallel execution is available and running on an AMD GPU as only AMD support it and again its only really useful when running things in parallel. Disable the async. compute fencing code when async. compute is disabled.

Change the Metal texture lock/unlock code to use the immediate getBytes API to read from the texture unless it is stored in Private memory and requires we use the blit-encoder. This means iOS texture locking won't generally need to use the blit encoder with its row alignment restrictions as all textures will be Shared. On Mac most textures will still be accessed via blit operations since Private memory is much more common than Managed.

Texture streaming build now takes into account the material texcoord scales applied to the texture sampling.
Also finds out which texcoord is being used when sampling textures (between 0 and 3 currently).
TexCoord analysis debug view shaders is now working with SM4 ane SM5.
StaticMeshComponents hold persistent data coming from the texture streaming build.

Change 2921682 on 2016/03/24 by Daniel.Wright
Planar reflections
* New actor and component
* The scene is rendered to texture with a mirrored camera and a clip plane each frame
* The reflection texture is then applied to opaque pixels in a deferred pass, with distance and angle from plane fades
* Translucent materials apply the nearest reflection plane in the base pass
* Planar reflections require the project setting 'Support global clip plane for Planar Reflections' to be enabled, since writing to SV_ClipDistance all the time adds about 15% BasePass GPU time on PS4
* Fixed global distance field in materials which had been broken since moving global distance field properties into the view uniform buffer
* Fixed PS4 removing system-value semantics when output from vertex shader and not read in next stage

Change 2772469 on 2015/11/18 by Daniel.Wright
Fixed SCW always exiting after compiling a long shader, now checks idle time starting from the end of the last compile task
Automated smoke tests aren't run in standalone programs which are frequently launched as they increase the startup time (doubles startup time of SCW as shown in sampling profile)

Change 2772471 on 2015/11/18 by Daniel.Wright
Particle SubUV cutouts
* A new asset type 'SubUV Animation' precomputes bounding geometry for every frame of a SubUV texture animation.
* Particle emitters with a SubUV module can then use this SubUV Animation to render with much tigher bounding geometry to reduce overdraw.
* GPU performance savings depend on how much empty space (zero alpha) existed in the texture. Measured a reduction of 2-3x GPU time on a smoke effect.
* This only works if the material does not modify opacity to reveal areas with zero texture alpha

Global distance field can be accessed via new DistanceToNearestSurface and DistanceFieldGradient material nodes
[CL 2555411 by Daniel Wright in Main branch]
* Screen grid resolution is 1/8th of primary resolution, but with 4x temporal supersampling through jittering subsample positions. A longer history filter is required to hide the jittering which can increase ghosting.
* The main benefit of doing cone tracing on a screen grid instead of the previous surface cache is that it's performance is generally constant regardless of camera movement or noisy geometry (foliage)
* A global distance field is now used for cone traces after a certain distance, DFAO is 2-4x faster as a result.
* The global distance field is composed of 4 128^3 clipmaps that follow the camera around
* Clipmaps are scrolled so that only new or dirty regions are updated due to camera or object movement, with close to 0 average GPU cost. Worst case update cost (camera teleport) is 5ms on 7870.
* The global distance field currently breaks Distance Field GI
* Overall with these changes DFAO in a Fortnite level is 3.4ms on a 7870 (3.8ms on PS4), and 4.0ms in the Kite demo on 7870.
