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.

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
Change 3251142 on 2017/01/09 by Ben.Woodhouse
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.

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

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:

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

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] 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] 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.

UE5_MAIN: Multi-view-family scene renderer refactor, part 2. Move FSceneTextures singleton out of RDG blackboard and FSceneTexturesConfig global variable singleton, into FViewFamilyInfo. This is necessary to allow multiple view families to render in a single render graph and a single scene renderer call.
* Existing calls to CreateSceneTextureShaderParameters and similar functions use "GetSceneTexturesChecked", which allows for the possibility that they are reached in a code path where scene textures haven't been initialized, and nullptr is returned instead of asserting. The shader parameter setup functions then fill in dummy defaults for that case. The goal was to precisely match the original behavior, which queried the RDG blackboard, and gracefully handled null if scene textures weren't there. This definitely appears to occur in FNiagaraGpuComputeDispatch::ProcessPendingTicksFlush, which can be called with a dummy scene with no scene textures. In the future, I may change this so dummy defaults are filled in for FSceneTextures at construction time, so the structure is never in an uninitialized state, but I would like to set up a test case for the Niagara code path before doing that, and the checks aren't harmful in the meantime.
* I marked as deprecated global functions which query values from FSceneTexturesConfig, but they'll still work with the caveat that if you use multi-view-family rendering, the results will be indeterminate (whatever view family rendered last). There was only one case outside the scene renderer that accessed the globals (depth clear value), which I removed, noting that there is nowhere in the code where we modify the depth clear value from its global default. I would like to permanently deprecate or remove these at some point. Display Cluster is the only code that's currently using the multi-view-family code path, and as a new (still incomplete) feature, third party code can't be using it, and won't be affected.

Change 3761995 by Mark.Satterthwaite
Add the Metal compiler path to the local .pch filename to avoid problems when Xcode moves.
Change 3761996 by Mark.Satterthwaite
Emit more details when a pixel shader is found to have no outputs at all which Metal doesn't permit. More likely this is a bug in the shader compiler not configuring the in-out mask correctly...
#jira UE-52292
Change 3761999 by Mark.Satterthwaite
No need to avoid tessellation for FMetalRHICommandContext::RHIEndDrawIndexedPrimitiveUP anymore - that was from back when the tessellation logic was replicated in each RHI*Draw* implementation.
#jira UE-51937
Change 3762181 by Joe.Graf
Changed MaxShaderJobBatchSize to 25 on Mac as it reduced shader compile time by 21%
Change 3762607 by Mark.Satterthwaite
Remove accidentally included changes from 3761995.
Change 3762612 by Mark.Satterthwaite
Enable the explicit sincos intrinsic for Metal to avoid instances of UE-52477 that can cause shaders to compile incorrectly through hlslcc.
#jira UE-52477
Change 3762772 by Michael.Lentine
Move RHI calls to render thread.
Change 3763021 by Richard.Wallis

Change 3763111 by Richard.Wallis
Clone of CL 3763033 (Release-4.18):
Fix for crash upon launching packaged game on Mac with Share Material Shader Code enabled.
#jira UE-52121
Change 3763657 by Michael.Lentine
Invalidate ddc for skeletal mesh render data so that the duplicated vertex render structures are properly serialized.
Change 3763727 by Jian.Ru
Fix Player Collision view mode. It is caused by checking an uninitialized vertex buffer so the check always fail.
#jira UE-52052
Change 3763738 by Guillaume.Abadie
Implements SSR input post process material location.
Change 3764271 by Mark.Satterthwaite
Allow ControlPointPatch lists to flow through MetalRHI as it was setup to handle this transparently - the VSHS compute shader will convert them to triangles to draw. Report the same warning as in the pipeline creation stage as this hasn't been formally validated.
#jira UE-52454
Change 3764316 by Daniel.Wright
Added AVolumetricLightmapDensityVolume - gives local control over Volumetric Lightmap density. Dropping the top mip outside of the play area in Monolith saves 20Mb (35Mb original).
Volumetric Lightmap no longer refines around static translucent geometry - saves 5Mb in Monolith
Reworked brick culling by error mechanism. Now compares error to interpolated parent lighting instead of the brick average - prevents dropping constant value bricks which are near a wall and cause leaking due to parent interpolation after being culled.
Change 3764318 by Daniel.Wright
Missing file
Change 3764321 by Daniel.Wright
Shader compiling memory optimizations
* Editor memory: Sharing uniform buffer includes and GeneratedInstancedStereo.ush per FShaderType (was previously duplicated per FShader job)
* SCW input size: Sharing uniform buffer includes and SharedEnvironment per batch
* 7.6Gb of shader job inputs in memory -> .5Gb (13x less) when doing a full shader compile of Paragon Editor
* 13.8Gb written into worker input files -> 2.9Gb (4.7x less). Global shaders are never batched when sent to SCW so unoptimized by these changes.
Change 3764595 by Daniel.Wright
Added VolumetricLightmapDensityVolume asset icons
Change 3764701 by Michael.Lentine
Add duplicated vertices merging for meshmerge.
Change 3766002 by Guillaume.Abadie

Clamp fetched texture coordinates to those available on the mesh.
Change 3767209 by Chris.Bunner
PR #4203: Early-outs in UMaterialInstance parameter setters (Contributed by stefanzimecki)
#jira UE-52193
Change 3767772 by Mark.Satterthwaite
MetalShaderFormat will no longer fallback to text shaders when you ask it to compile to bytecode but the bytecode compiler is not available (either locally or remotely) - this ensures that the DDC can't be poisoned by incorrectly configured clients. The Editor is already setup such that if the remote shader compiler is not configured & Xcode is not available locally the shader-compiler will be invoked to generate text shaders.
#jira UE-52554
Change 3768604 by Guillaume.Abadie
Polish up with new global shader function signature.
Change 3768993 by Guillaume.Abadie
Fixes r.Upscale.Panini cvars
Change 3769478 by Mark.Satterthwaite
Move the ue4_stdlib.metal & PCH into a temporary directory that exists for the lifetime of the SCW on the remote side as well as the local one and add this path as an include directory.
#jira UE-52587
Change 3769703 by Mark.Satterthwaite
For all Metal platforms >= Metal v1.2 transform mul(a,b) into fma(a,b,0) to prevent the Apple compiler reordering operations differently between the base & depth passes which results in variance in the position output.
For iOS disable fast-math when the vertex-shader uses World-Position-Offset because there are additional problems on the iOS shader compiler that result in position variance even with the above fix - WPO performance will suffer but I don't have any alternatives.
Remove the depth-offset hack from the depth-only vertex shader again.
#jira UES-5651
Change 3769763 by Mark.Satterthwaite
Handle swizzle's in the hlslcc fma identification pass so that we reduce the number of instructions and the platform compiler can't break the instructions up.
Change 3769849 by Mark.Satterthwaite
Fix CIS error.
Change 3770517 by Richard.Wallis
Fix for crash when creating a new media texture (AppleIntelHD5000GraphicsMTLDriver!SamplerStage::bindSamplerToTexture()). Missing texture resource for binding. Old InitDynamicRHI() code has been refactored out into seperate functions which leaves us on Mac with a NULL resource initially after creation which Metal doesn't like. This fix puts InitDynamicRHI down the default setup/clear path which inits default resources - I don't think we should use a global dummy in this instance as this is a render target.
#jira UE-51940
Change 3770688 by Uriel.Doyon
Fixed texture resolution returning 0 when running blueprint construction scripts at cook time.
Change 3771115 by Mark.Satterthwaite
Report errors from failed attempts to compile global shaders or we can't see why things fail on non-Windows platforms.
Change 3771263 by Mark.Satterthwaite
Change the way ManualVertexFetch is enabled on Metal platforms so that it is enabled when targeting Metal v1.2 and higher (macOS 10.12+/iOS 10+). This brings iOS in the Desktop Forward renderer back into line with the Mac.
#jira UERNDR-300
Change 3773472 by Guillaume.Abadie
Fixes a crash on PIE of SimpleComposure project.
Change 3773475 by Guillaume.Abadie
Fixes bug in editor viewport caused by SSR input changes.
Change 3774677 by Arne.Schober
DR - Deprecated SetLocal from the RHICmdlist
Fixed some unnecessary PSO collisions.
Change 3777037 by Mark.Satterthwaite
Remove incorrect change that caused a reference to "accurate::sincos" to appear in some Metal shaders rather than "precise::sincos".
Change 3777122 by Mark.Satterthwaite
Back out changelist 3777037 - I'm blind and wasn't seeing the real problem was a stale shader cache...
Change 3777196 by Mark.Satterthwaite
Fix text-shader compilation on iOS 10 - maybe iOS 9 too (untested!).
We need our own make_scalar type-trait template for ue4_stdlib.metal so that we still compile with older iOS runtime compilers and we can't use as_type to directly implement the packHalf2x16/unpackHalf2x16 intrinsics for these older runtime compilers either.
Change 3779098 by Rolando.Caloca
DR - vk - Fix query index
Change 3779275 by Mark.Satterthwaite
Silence the Metal runtime compiler warning caused by use of a deprecated enum value when running text shaders compiled for Metal v1.0/1.1 on a Metal v1.2+ OS.

Change 3779608 by Uriel.Doyon
Fixed invalid access in the resave package commantlet when building texture streaming material data for materials enabling tesselation.
Change 3784496 by Mark.Satterthwaite
Temporarily disable USE_OBJECT_COMPOSITING_TILE_CULLING for Metal shader compilation only - other platforms are unaffected - as it isn't working properly for some reason. need to work out what's up but don't want Distance Fields to be completely snookered in the interim.
#jira UE-52952
Change 3784608 by Rolando.Caloca
DR - Copy 3784588

Change 3784734 by Mark.Satterthwaite
Real fix for UE-52952 - MetalShaderFormat wasn't propagating the full thread-group value.
#jira UE-52952
Change 3784741 by Mark.Satterthwaite
More Metal debugging commandline options "-metalfastmath" & "-metalnofastmath" to force fast-math on or off for all shaders, must be using runtime-compiled shaders (i.e. -metalshaderdebug or r.Shaders.Optimise=0) to take effect.
Change 3787103 by Guillaume.Abadie

Change 3787207 by Guillaume.Abadie

Change 3788028 by Peter.Sumanaseni
Working linear HDR exr output from sequencer
Change 3788536 by Mark.Satterthwaite
Track whether the Metal shader uses the discard_fragment function as when this is used but without any other outputs we know we need to bind at least one render-target or a depth-stencil surface but we don't know which. This lets us correctly error when we encounter a shader with no outputs at all which Metal doesn't permit.
#jira UE-52292
Change 3788538 by Mark.Satterthwaite
Let's try mitigating UE-46604 on Nvidia by retaining resource references in the command-buffer. This shouldn't be necessary and isn't typically on other vendors but we haven't been able to reproduce this reliably enough to get to the bottom of it.

Change 3791884 by Daniel.Wright
Added BP setter for LowerHemisphereColor
Change 3791886 by Daniel.Wright
Added LightmapType to PrimitiveComponent
* ForceVolumetric allows forcing static geometry to use Volumetric Lightmaps, which can be useful on instanced foliage where seams are prevalent. Lightmass internal caching still requires lightmap UVs and reasonable lightmap resolution.
* ForceSurface replaces bLightAsIfStatic
Improvements to Volumetric Lightmap quality needed for static geometry
* Stationary light shadowing is now dilated inside geometry
* Now doing two dilation passes since samples near geometry see inside due to ray start bias
* Refinement around geometry uses an expanded cell bounds when the geometry is going to use Volumetric Lightmaps, since cross-resolution stitching causes leaking
Lightmass debug primitives are now tied to a swarm task instead of global - allows debugging of Volumetric Lightmap tasks
Change 3792256 by Guillaume.Abadie
Fixes a bug where permutation was not actually serialised in FShader, so was ending up recompiling shader at every load.

Change 3794627 by Mark.Satterthwaite
Implement two components for MTLPP, an IMP cache for Objective-C selector implementations & an interposition framework for those same selectors:
- imp_SelectorCache & friends provide the IMP caching for each of the Metal protocols which constitute most of the API, so far I've not covered the Metal classes used for the various descriptor/initializer types. Each type has its own IMPTable which caches the selector's implementation pointer and provides the mechanism to hook that implementation. As Objective-C is runtime dynamic this look up must be performed on the actual Class value returned by an object at runtime - you can't do this at compile time. Even things like NSString which appear compile-time static are really not as NSString is an alias for a class-cluster (NSString, NSMutableString, __NSInlineString and more).
- The interpose directory contains MTI* files which are the framework for interposing all the functions in Metal's runtime API - I deliberately omit the descriptor classes & read-only functions as there's no benefit to interposing them - which I can build off to create a trace tool or a superior validation layer. Right now this is Mac only as there'll be some problems to solve for iOS/tvOS due to difference in linking requirements - not insurmountable.
- Rebuild MTLPP's implementation of the C++ wrapper classes around the IMPTable's - this means we avoid all the objc_msgSend overhead for all the classes and functions whose implementations are cached. Right now the IMPTable is going to incur a look-up for all non-copy/move constructors which is suboptimal - ideally the Metal IMPTables would be cached in the Device object as they will be consistent within a single Device.
- Sort out the MTLPP availability logic - it now exports the availability warnings to the caller and internally just blithely assumes it may call the functions, the caller is responsible for ensuring that calls are made only on appropriate devices & OSes. This reduces MTLPP complexity and better fits how MetalRHI works.
- Fix a number of retain/release bugs that were lying dormant in MTLPP but exposed by the switch to IMPTables.
- Add tvOS support.
Next up, put this into MetalRHI and start fixing all the fallout.

Change 3764316 by Daniel.Wright
Added AVolumetricLightmapDensityVolume - gives local control over Volumetric Lightmap density. Dropping the top mip outside of the play area in Monolith saves 20Mb (35Mb original).
Volumetric Lightmap no longer refines around static translucent geometry - saves 5Mb in Monolith
Reworked brick culling by error mechanism. Now compares error to interpolated parent lighting instead of the brick average - prevents dropping constant value bricks which are near a wall and cause leaking due to parent interpolation after being culled.

Shader compiling memory optimizations
* Editor memory: Sharing uniform buffer includes and GeneratedInstancedStereo.ush per FShaderType (was previously duplicated per FShader job)
* SCW input size: Sharing uniform buffer includes and SharedEnvironment per batch
* 7.6Gb of shader job inputs in memory -> .5Gb (13x less) when doing a full shader compile of Paragon Editor
* 13.8Gb written into worker input files -> 2.9Gb (4.7x less). Global shaders are never batched when sent to SCW so unoptimized by these changes.

MetalShaderFormat will no longer fallback to text shaders when you ask it to compile to bytecode but the bytecode compiler is not available (either locally or remotely) - this ensures that the DDC can't be poisoned by incorrectly configured clients. The Editor is already setup such that if the remote shader compiler is not configured & Xcode is not available locally the shader-compiler will be invoked to generate text shaders.

Change 3769703 by Mark.Satterthwaite
For all Metal platforms >= Metal v1.2 transform mul(a,b) into fma(a,b,0) to prevent the Apple compiler reordering operations differently between the base & depth passes which results in variance in the position output.
For iOS disable fast-math when the vertex-shader uses World-Position-Offset because there are additional problems on the iOS shader compiler that result in position variance even with the above fix - WPO performance will suffer but I don't have any alternatives.
Remove the depth-offset hack from the depth-only vertex shader again.

Change 3770517 by Richard.Wallis
Fix for crash when creating a new media texture (AppleIntelHD5000GraphicsMTLDriver!SamplerStage::bindSamplerToTexture()). Missing texture resource for binding. Old InitDynamicRHI() code has been refactored out into seperate functions which leaves us on Mac with a NULL resource initially after creation which Metal doesn't like. This fix puts InitDynamicRHI down the default setup/clear path which inits default resources - I don't think we should use a global dummy in this instance as this is a render target.

Fix text-shader compilation on iOS 10 - maybe iOS 9 too (untested!).

Added LightmapType to PrimitiveComponent
* ForceVolumetric allows forcing static geometry to use Volumetric Lightmaps, which can be useful on instanced foliage where seams are prevalent. Lightmass internal caching still requires lightmap UVs and reasonable lightmap resolution.
* ForceSurface replaces bLightAsIfStatic
Improvements to Volumetric Lightmap quality needed for static geometry
* Stationary light shadowing is now dilated inside geometry
* Now doing two dilation passes since samples near geometry see inside due to ray start bias
* Refinement around geometry uses an expanded cell bounds when the geometry is going to use Volumetric Lightmaps, since cross-resolution stitching causes leaking
Lightmass debug primitives are now tied to a swarm task instead of global - allows debugging of Volumetric Lightmap tasks

Implement two components for MTLPP, an IMP cache for Objective-C selector implementations & an interposition framework for those same selectors:
- imp_SelectorCache & friends provide the IMP caching for each of the Metal protocols which constitute most of the API, so far I've not covered the Metal classes used for the various descriptor/initializer types. Each type has its own IMPTable which caches the selector's implementation pointer and provides the mechanism to hook that implementation. As Objective-C is runtime dynamic this look up must be performed on the actual Class value returned by an object at runtime - you can't do this at compile time. Even things like NSString which appear compile-time static are really not as NSString is an alias for a class-cluster (NSString, NSMutableString, __NSInlineString and more).
- The interpose directory contains MTI* files which are the framework for interposing all the functions in Metal's runtime API - I deliberately omit the descriptor classes & read-only functions as there's no benefit to interposing them - which I can build off to create a trace tool or a superior validation layer. Right now this is Mac only as there'll be some problems to solve for iOS/tvOS due to difference in linking requirements - not insurmountable.
- Rebuild MTLPP's implementation of the C++ wrapper classes around the IMPTable's - this means we avoid all the objc_msgSend overhead for all the classes and functions whose implementations are cached. Right now the IMPTable is going to incur a look-up for all non-copy/move constructors which is suboptimal - ideally the Metal IMPTables would be cached in the Device object as they will be consistent within a single Device.
- Sort out the MTLPP availability logic - it now exports the availability warnings to the caller and internally just blithely assumes it may call the functions, the caller is responsible for ensuring that calls are made only on appropriate devices & OSes. This reduces MTLPP complexity and better fits how MetalRHI works.
- Fix a number of retain/release bugs that were lying dormant in MTLPP but exposed by the switch to IMPTables.
- Add tvOS support.
Next up, put this into MetalRHI and start fixing all the fallout.

Change 3764316 by Daniel.Wright
Added AVolumetricLightmapDensityVolume - gives local control over Volumetric Lightmap density. Dropping the top mip outside of the play area in Monolith saves 20Mb (35Mb original).
Volumetric Lightmap no longer refines around static translucent geometry - saves 5Mb in Monolith
Reworked brick culling by error mechanism. Now compares error to interpolated parent lighting instead of the brick average - prevents dropping constant value bricks which are near a wall and cause leaking due to parent interpolation after being culled.

Shader compiling memory optimizations
* Editor memory: Sharing uniform buffer includes and GeneratedInstancedStereo.ush per FShaderType (was previously duplicated per FShader job)
* SCW input size: Sharing uniform buffer includes and SharedEnvironment per batch
* 7.6Gb of shader job inputs in memory -> .5Gb (13x less) when doing a full shader compile of Paragon Editor
* 13.8Gb written into worker input files -> 2.9Gb (4.7x less). Global shaders are never batched when sent to SCW so unoptimized by these changes.

MetalShaderFormat will no longer fallback to text shaders when you ask it to compile to bytecode but the bytecode compiler is not available (either locally or remotely) - this ensures that the DDC can't be poisoned by incorrectly configured clients.

Change 3769703 by Mark.Satterthwaite
For all Metal platforms >= Metal v1.2 transform mul(a,b) into fma(a,b,0) to prevent the Apple compiler reordering operations differently between the base & depth passes which results in variance in the position output.
For iOS disable fast-math when the vertex-shader uses World-Position-Offset because there are additional problems on the iOS shader compiler that result in position variance even with the above fix - WPO performance will suffer but I don't have any alternatives.
Remove the depth-offset hack from the depth-only vertex shader again.

Fix for crash when creating a new media texture (AppleIntelHD5000GraphicsMTLDriver!SamplerStage::bindSamplerToTexture()). Missing texture resource for binding. Old InitDynamicRHI() code has been refactored out into seperate functions which leaves us on Mac with a NULL resource initially after creation which Metal doesn't like. This fix puts InitDynamicRHI down the default setup/clear path which inits default resources - I don't think we should use a global dummy in this instance as this is a render target.

Added LightmapType to PrimitiveComponent
* ForceVolumetric allows forcing static geometry to use Volumetric Lightmaps, which can be useful on instanced foliage where seams are prevalent. Lightmass internal caching still requires lightmap UVs and reasonable lightmap resolution.
* ForceSurface replaces bLightAsIfStatic
Improvements to Volumetric Lightmap quality needed for static geometry
* Stationary light shadowing is now dilated inside geometry
* Now doing two dilation passes since samples near geometry see inside due to ray start bias
* Refinement around geometry uses an expanded cell bounds when the geometry is going to use Volumetric Lightmaps, since cross-resolution stitching causes leaking
Lightmass debug primitives are now tied to a swarm task instead of global - allows debugging of Volumetric Lightmap tasks

Implement two components for MTLPP, an IMP cache for Objective-C selector implementations & an interposition framework for those same selectors:
- imp_SelectorCache & friends provide the IMP caching for each of the Metal protocols which constitute most of the API, so far I've not covered the Metal classes used for the various descriptor/initializer types. Each type has its own IMPTable which caches the selector's implementation pointer and provides the mechanism to hook that implementation. As Objective-C is runtime dynamic this look up must be performed on the actual Class value returned by an object at runtime - you can't do this at compile time. Even things like NSString which appear compile-time static are really not as NSString is an alias for a class-cluster (NSString, NSMutableString, __NSInlineString and more).
- The interpose directory contains MTI* files which are the framework for interposing all the functions in Metal's runtime API - I deliberately omit the descriptor classes & read-only functions as there's no benefit to interposing them - which I can build off to create a trace tool or a superior validation layer. Right now this is Mac only as there'll be some problems to solve for iOS/tvOS due to difference in linking requirements - not insurmountable.
- Rebuild MTLPP's implementation of the C++ wrapper classes around the IMPTable's - this means we avoid all the objc_msgSend overhead for all the classes and functions whose implementations are cached. Right now the IMPTable is going to incur a look-up for all non-copy/move constructors which is suboptimal - ideally the Metal IMPTables would be cached in the Device object as they will be consistent within a single Device.
- Sort out the MTLPP availability logic - it now exports the availability warnings to the caller and internally just blithely assumes it may call the functions, the caller is responsible for ensuring that calls are made only on appropriate devices & OSes. This reduces MTLPP complexity and better fits how MetalRHI works.
- Fix a number of retain/release bugs that were lying dormant in MTLPP but exposed by the switch to IMPTables.
- Add tvOS support.
Next up, put this into MetalRHI and start fixing all the fallout.

Change 3769703 by Mark.Satterthwaite
For all Metal platforms >= Metal v1.2 transform mul(a,b) into fma(a,b,0) to prevent the Apple compiler reordering operations differently between the base & depth passes which results in variance in the position output.
For iOS disable fast-math when the vertex-shader uses World-Position-Offset because there are additional problems on the iOS shader compiler that result in position variance even with the above fix - WPO performance will suffer but I don't have any alternatives.
Remove the depth-offset hack from the depth-only vertex shader again.

Fix for crash when creating a new media texture (AppleIntelHD5000GraphicsMTLDriver!SamplerStage::bindSamplerToTexture()). Missing texture resource for binding. Old InitDynamicRHI() code has been refactored out into seperate functions which leaves us on Mac with a NULL resource initially after creation which Metal doesn't like. This fix puts InitDynamicRHI down the default setup/clear path which inits default resources - I don't think we should use a global dummy in this instance as this is a render target.

Added LightmapType to PrimitiveComponent
* ForceVolumetric allows forcing static geometry to use Volumetric Lightmaps, which can be useful on instanced foliage where seams are prevalent. Lightmass internal caching still requires lightmap UVs and reasonable lightmap resolution.
* ForceSurface replaces bLightAsIfStatic
Improvements to Volumetric Lightmap quality needed for static geometry
* Stationary light shadowing is now dilated inside geometry
* Now doing two dilation passes since samples near geometry see inside due to ray start bias
* Refinement around geometry uses an expanded cell bounds when the geometry is going to use Volumetric Lightmaps, since cross-resolution stitching causes leaking
Lightmass debug primitives are now tied to a swarm task instead of global - allows debugging of Volumetric Lightmap tasks

Implement two components for MTLPP, an IMP cache for Objective-C selector implementations & an interposition framework for those same selectors:
- imp_SelectorCache & friends provide the IMP caching for each of the Metal protocols which constitute most of the API, so far I've not covered the Metal classes used for the various descriptor/initializer types. Each type has its own IMPTable which caches the selector's implementation pointer and provides the mechanism to hook that implementation. As Objective-C is runtime dynamic this look up must be performed on the actual Class value returned by an object at runtime - you can't do this at compile time. Even things like NSString which appear compile-time static are really not as NSString is an alias for a class-cluster (NSString, NSMutableString, __NSInlineString and more).
- The interpose directory contains MTI* files which are the framework for interposing all the functions in Metal's runtime API - I deliberately omit the descriptor classes & read-only functions as there's no benefit to interposing them - which I can build off to create a trace tool or a superior validation layer. Right now this is Mac only as there'll be some problems to solve for iOS/tvOS due to difference in linking requirements - not insurmountable.
- Rebuild MTLPP's implementation of the C++ wrapper classes around the IMPTable's - this means we avoid all the objc_msgSend overhead for all the classes and functions whose implementations are cached. Right now the IMPTable is going to incur a look-up for all non-copy/move constructors which is suboptimal - ideally the Metal IMPTables would be cached in the Device object as they will be consistent within a single Device.
- Sort out the MTLPP availability logic - it now exports the availability warnings to the caller and internally just blithely assumes it may call the functions, the caller is responsible for ensuring that calls are made only on appropriate devices & OSes. This reduces MTLPP complexity and better fits how MetalRHI works.
- Fix a number of retain/release bugs that were lying dormant in MTLPP but exposed by the switch to IMPTables.
- Add tvOS support.
Next up, put this into MetalRHI and start fixing all the fallout.

Added AVolumetricLightmapDensityVolume - gives local control over Volumetric Lightmap density. Dropping the top mip outside of the play area in Monolith saves 20Mb (35Mb original).
Volumetric Lightmap no longer refines around static translucent geometry - saves 5Mb in Monolith
Reworked brick culling by error mechanism. Now compares error to interpolated parent lighting instead of the brick average - prevents dropping constant value bricks which are near a wall and cause leaking due to parent interpolation after being culled.

Shader compiling memory optimizations
* Editor memory: Sharing uniform buffer includes and GeneratedInstancedStereo.ush per FShaderType (was previously duplicated per FShader job)
* SCW input size: Sharing uniform buffer includes and SharedEnvironment per batch
* 7.6Gb of shader job inputs in memory -> .5Gb (13x less) when doing a full shader compile of Paragon Editor
* 13.8Gb written into worker input files -> 2.9Gb (4.7x less). Global shaders are never batched when sent to SCW so unoptimized by these changes.

MetalShaderFormat will no longer fallback to text shaders when you ask it to compile to bytecode but the bytecode compiler is not available (either locally or remotely) - this ensures that the DDC can't be poisoned by incorrectly configured clients.

For all Metal platforms >= Metal v1.2 transform mul(a,b) into fma(a,b,0) to prevent the Apple compiler reordering operations differently between the base & depth passes which results in variance in the position output.
For iOS disable fast-math when the vertex-shader uses World-Position-Offset because there are additional problems on the iOS shader compiler that result in position variance even with the above fix - WPO performance will suffer but I don't have any alternatives.

Fix for crash when creating a new media texture (AppleIntelHD5000GraphicsMTLDriver!SamplerStage::bindSamplerToTexture()). Missing texture resource for binding. Old InitDynamicRHI() code has been refactored out into seperate functions which leaves us on Mac with a NULL resource initially after creation which Metal doesn't like. This fix puts InitDynamicRHI down the default setup/clear path which inits default resources - I don't think we should use a global dummy in this instance as this is a render target.

Added LightmapType to PrimitiveComponent
* ForceVolumetric allows forcing static geometry to use Volumetric Lightmaps, which can be useful on instanced foliage where seams are prevalent. Lightmass internal caching still requires lightmap UVs and reasonable lightmap resolution.
* ForceSurface replaces bLightAsIfStatic
Improvements to Volumetric Lightmap quality needed for static geometry
* Stationary light shadowing is now dilated inside geometry
* Now doing two dilation passes since samples near geometry see inside due to ray start bias
* Refinement around geometry uses an expanded cell bounds when the geometry is going to use Volumetric Lightmaps, since cross-resolution stitching causes leaking
Lightmass debug primitives are now tied to a swarm task instead of global - allows debugging of Volumetric Lightmap tasks

Implement two components for MTLPP, an IMP cache for Objective-C selector implementations & an interposition framework for those same selectors:
- imp_SelectorCache & friends provide the IMP caching for each of the Metal protocols which constitute most of the API, so far I've not covered the Metal classes used for the various descriptor/initializer types. Each type has its own IMPTable which caches the selector's implementation pointer and provides the mechanism to hook that implementation. As Objective-C is runtime dynamic this look up must be performed on the actual Class value returned by an object at runtime - you can't do this at compile time. Even things like NSString which appear compile-time static are really not as NSString is an alias for a class-cluster (NSString, NSMutableString, __NSInlineString and more).
- The interpose directory contains MTI* files which are the framework for interposing all the functions in Metal's runtime API - I deliberately omit the descriptor classes & read-only functions as there's no benefit to interposing them - which I can build off to create a trace tool or a superior validation layer. Right now this is Mac only as there'll be some problems to solve for iOS/tvOS due to difference in linking requirements - not insurmountable.
- Rebuild MTLPP's implementation of the C++ wrapper classes around the IMPTable's - this means we avoid all the objc_msgSend overhead for all the classes and functions whose implementations are cached. Right now the IMPTable is going to incur a look-up for all non-copy/move constructors which is suboptimal - ideally the Metal IMPTables would be cached in the Device object as they will be consistent within a single Device.
- Sort out the MTLPP availability logic - it now exports the availability warnings to the caller and internally just blithely assumes it may call the functions, the caller is responsible for ensuring that calls are made only on appropriate devices & OSes. This reduces MTLPP complexity and better fits how MetalRHI works.
- Fix a number of retain/release bugs that were lying dormant in MTLPP but exposed by the switch to IMPTables.
- Add tvOS support.
Next up, put this into MetalRHI and start fixing all the fallout.

Added AVolumetricLightmapDensityVolume - gives local control over Volumetric Lightmap density. Dropping the top mip outside of the play area in Monolith saves 20Mb (35Mb original).
Volumetric Lightmap no longer refines around static translucent geometry - saves 5Mb in Monolith
Reworked brick culling by error mechanism. Now compares error to interpolated parent lighting instead of the brick average - prevents dropping constant value bricks which are near a wall and cause leaking due to parent interpolation after being culled.

Shader compiling memory optimizations
* Editor memory: Sharing uniform buffer includes and GeneratedInstancedStereo.ush per FShaderType (was previously duplicated per FShader job)
* SCW input size: Sharing uniform buffer includes and SharedEnvironment per batch
* 7.6Gb of shader job inputs in memory -> .5Gb (13x less) when doing a full shader compile of Paragon Editor
* 13.8Gb written into worker input files -> 2.9Gb (4.7x less). Global shaders are never batched when sent to SCW so unoptimized by these changes.

MetalShaderFormat will no longer fallback to text shaders when you ask it to compile to bytecode but the bytecode compiler is not available (either locally or remotely) - this ensures that the DDC can't be poisoned by incorrectly configured clients.

For all Metal platforms >= Metal v1.2 transform mul(a,b) into fma(a,b,0) to prevent the Apple compiler reordering operations differently between the base & depth passes which results in variance in the position output.
For iOS disable fast-math when the vertex-shader uses World-Position-Offset because there are additional problems on the iOS shader compiler that result in position variance even with the above fix - WPO performance will suffer but I don't have any alternatives.

Fix for crash when creating a new media texture (AppleIntelHD5000GraphicsMTLDriver!SamplerStage::bindSamplerToTexture()). Missing texture resource for binding. Old InitDynamicRHI() code has been refactored out into seperate functions which leaves us on Mac with a NULL resource initially after creation which Metal doesn't like. This fix puts InitDynamicRHI down the default setup/clear path which inits default resources - I don't think we should use a global dummy in this instance as this is a render target.

* Refinement around geometry uses an expanded cell bounds when the geometry is going to use Volumetric Lightmaps, since cross-resolution stitching causes leaking
Lightmass debug primitives are now tied to a swarm task instead of global - allows debugging of Volumetric Lightmap tasks

Implement two components for MTLPP, an IMP cache for Objective-C selector implementations & an interposition framework for those same selectors:
- imp_SelectorCache & friends provide the IMP caching for each of the Metal protocols which constitute most of the API, so far I've not covered the Metal classes used for the various descriptor/initializer types. Each type has its own IMPTable which caches the selector's implementation pointer and provides the mechanism to hook that implementation. As Objective-C is runtime dynamic this look up must be performed on the actual Class value returned by an object at runtime - you can't do this at compile time. Even things like NSString which appear compile-time static are really not as NSString is an alias for a class-cluster (NSString, NSMutableString, __NSInlineString and more).
- The interpose directory contains MTI* files which are the framework for interposing all the functions in Metal's runtime API - I deliberately omit the descriptor classes & read-only functions as there's no benefit to interposing them - which I can build off to create a trace tool or a superior validation layer. Right now this is Mac only as there'll be some problems to solve for iOS/tvOS due to difference in linking requirements - not insurmountable.
- Rebuild MTLPP's implementation of the C++ wrapper classes around the IMPTable's - this means we avoid all the objc_msgSend overhead for all the classes and functions whose implementations are cached. Right now the IMPTable is going to incur a look-up for all non-copy/move constructors which is suboptimal - ideally the Metal IMPTables would be cached in the Device object as they will be consistent within a single Device.
- Sort out the MTLPP availability logic - it now exports the availability warnings to the caller and internally just blithely assumes it may call the functions, the caller is responsible for ensuring that calls are made only on appropriate devices & OSes. This reduces MTLPP complexity and better fits how MetalRHI works.
- Fix a number of retain/release bugs that were lying dormant in MTLPP but exposed by the switch to IMPTables.
- Add tvOS support.
Next up, put this into MetalRHI and start fixing all the fallout.

#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

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.

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.

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.

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

Change 3764316 by Daniel.Wright
Added AVolumetricLightmapDensityVolume - gives local control over Volumetric Lightmap density. Dropping the top mip outside of the play area in Monolith saves 20Mb (35Mb original).
Volumetric Lightmap no longer refines around static translucent geometry - saves 5Mb in Monolith
Reworked brick culling by error mechanism. Now compares error to interpolated parent lighting instead of the brick average - prevents dropping constant value bricks which are near a wall and cause leaking due to parent interpolation after being culled.

Shader compiling memory optimizations
* Editor memory: Sharing uniform buffer includes and GeneratedInstancedStereo.ush per FShaderType (was previously duplicated per FShader job)
* SCW input size: Sharing uniform buffer includes and SharedEnvironment per batch
* 7.6Gb of shader job inputs in memory -> .5Gb (13x less) when doing a full shader compile of Paragon Editor
* 13.8Gb written into worker input files -> 2.9Gb (4.7x less). Global shaders are never batched when sent to SCW so unoptimized by these changes.

MetalShaderFormat will no longer fallback to text shaders when you ask it to compile to bytecode but the bytecode compiler is not available (either locally or remotely) - this ensures that the DDC can't be poisoned by incorrectly configured clients.

Change 3769703 by Mark.Satterthwaite
For all Metal platforms >= Metal v1.2 transform mul(a,b) into fma(a,b,0) to prevent the Apple compiler reordering operations differently between the base & depth passes which results in variance in the position output.
For iOS disable fast-math when the vertex-shader uses World-Position-Offset because there are additional problems on the iOS shader compiler that result in position variance even with the above fix - WPO performance will suffer but I don't have any alternatives.
Remove the depth-offset hack from the depth-only vertex shader again.

Fix for crash when creating a new media texture (AppleIntelHD5000GraphicsMTLDriver!SamplerStage::bindSamplerToTexture()). Missing texture resource for binding. Old InitDynamicRHI() code has been refactored out into seperate functions which leaves us on Mac with a NULL resource initially after creation which Metal doesn't like. This fix puts InitDynamicRHI down the default setup/clear path which inits default resources - I don't think we should use a global dummy in this instance as this is a render target.

Fix text-shader compilation on iOS 10 - maybe iOS 9 too (untested!).

Track whether the Metal shader uses the discard_fragment function as when this is used but without any other outputs we know we need to bind at least one render-target or a depth-stencil surface but we don't know which.

Added LightmapType to PrimitiveComponent
* ForceVolumetric allows forcing static geometry to use Volumetric Lightmaps, which can be useful on instanced foliage where seams are prevalent. Lightmass internal caching still requires lightmap UVs and reasonable lightmap resolution.
* ForceSurface replaces bLightAsIfStatic
Improvements to Volumetric Lightmap quality needed for static geometry
* Stationary light shadowing is now dilated inside geometry
* Now doing two dilation passes since samples near geometry see inside due to ray start bias
* Refinement around geometry uses an expanded cell bounds when the geometry is going to use Volumetric Lightmaps, since cross-resolution stitching causes leaking
Lightmass debug primitives are now tied to a swarm task instead of global - allows debugging of Volumetric Lightmap tasks

Implement two components for MTLPP, an IMP cache for Objective-C selector implementations & an interposition framework for those same selectors:
- imp_SelectorCache & friends provide the IMP caching for each of the Metal protocols which constitute most of the API, so far I've not covered the Metal classes used for the various descriptor/initializer types. Each type has its own IMPTable which caches the selector's implementation pointer and provides the mechanism to hook that implementation. As Objective-C is runtime dynamic this look up must be performed on the actual Class value returned by an object at runtime - you can't do this at compile time. Even things like NSString which appear compile-time static are really not as NSString is an alias for a class-cluster (NSString, NSMutableString, __NSInlineString and more).
- The interpose directory contains MTI* files which are the framework for interposing all the functions in Metal's runtime API - I deliberately omit the descriptor classes & read-only functions as there's no benefit to interposing them - which I can build off to create a trace tool or a superior validation layer. Right now this is Mac only as there'll be some problems to solve for iOS/tvOS due to difference in linking requirements - not insurmountable.
- Rebuild MTLPP's implementation of the C++ wrapper classes around the IMPTable's - this means we avoid all the objc_msgSend overhead for all the classes and functions whose implementations are cached. Right now the IMPTable is going to incur a look-up for all non-copy/move constructors which is suboptimal - ideally the Metal IMPTables would be cached in the Device object as they will be consistent within a single Device.
- Sort out the MTLPP availability logic - it now exports the availability warnings to the caller and internally just blithely assumes it may call the functions, the caller is responsible for ensuring that calls are made only on appropriate devices & OSes. This reduces MTLPP complexity and better fits how MetalRHI works.
- Fix a number of retain/release bugs that were lying dormant in MTLPP but exposed by the switch to IMPTables.
- Add tvOS support.
Next up, put this into MetalRHI and start fixing all the fallout.

#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.

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.

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.

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.

Change 3761437 by Guillaume.Abadie
Optimises motion blur compute shader for consoles.
Change 3761483 by Guillaume.Abadie
Fixes D3D11 RHI lying to dynamic resolution heuristic with t.MaxFPS.
Change 3761995 by Mark.Satterthwaite
Add the Metal compiler path to the local .pch filename to avoid problems when Xcode moves.
Change 3761996 by Mark.Satterthwaite
Emit more details when a pixel shader is found to have no outputs at all which Metal doesn't permit. More likely this is a bug in the shader compiler not configuring the in-out mask correctly...
#jira UE-52292
Change 3761999 by Mark.Satterthwaite
No need to avoid tessellation for FMetalRHICommandContext::RHIEndDrawIndexedPrimitiveUP anymore - that was from back when the tessellation logic was replicated in each RHI*Draw* implementation.
#jira UE-51937
Change 3762181 by Joe.Graf
Changed MaxShaderJobBatchSize to 25 on Mac as it reduced shader compile time by 21%
Change 3762607 by Mark.Satterthwaite
Remove accidentally included changes from 3761995.
Change 3762612 by Mark.Satterthwaite
Enable the explicit sincos intrinsic for Metal to avoid instances of UE-52477 that can cause shaders to compile incorrectly through hlslcc.
#jira UE-52477

Change 3763111 by Richard.Wallis
Clone of CL 3763033 (Release-4.18):
Fix for crash upon launching packaged game on Mac with Share Material Shader Code enabled.
#jira UE-52121
Change 3763657 by Michael.Lentine
Invalidate ddc for skeletal mesh render data so that the duplicated vertex render structures are properly serialized.
Change 3763727 by Jian.Ru
Fix Player Collision view mode. It is caused by checking an uninitialized vertex buffer so the check always fail.
#jira UE-52052
Change 3763738 by Guillaume.Abadie
Implements SSR input post process material location.
Change 3764271 by Mark.Satterthwaite
Allow ControlPointPatch lists to flow through MetalRHI as it was setup to handle this transparently - the VSHS compute shader will convert them to triangles to draw. Report the same warning as in the pipeline creation stage as this hasn't been formally validated.
#jira UE-52454
Change 3764316 by Daniel.Wright
Added AVolumetricLightmapDensityVolume - gives local control over Volumetric Lightmap density. Dropping the top mip outside of the play area in Monolith saves 20Mb (35Mb original).
Volumetric Lightmap no longer refines around static translucent geometry - saves 5Mb in Monolith
Reworked brick culling by error mechanism. Now compares error to interpolated parent lighting instead of the brick average - prevents dropping constant value bricks which are near a wall and cause leaking due to parent interpolation after being culled.
Change 3764318 by Daniel.Wright
Missing file
Change 3764321 by Daniel.Wright
Shader compiling memory optimizations
* Editor memory: Sharing uniform buffer includes and GeneratedInstancedStereo.ush per FShaderType (was previously duplicated per FShader job)
* SCW input size: Sharing uniform buffer includes and SharedEnvironment per batch
* 7.6Gb of shader job inputs in memory -> .5Gb (13x less) when doing a full shader compile of Paragon Editor
* 13.8Gb written into worker input files -> 2.9Gb (4.7x less). Global shaders are never batched when sent to SCW so unoptimized by these changes.

MetalShaderFormat will no longer fallback to text shaders when you ask it to compile to bytecode but the bytecode compiler is not available (either locally or remotely) - this ensures that the DDC can't be poisoned by incorrectly configured clients. The Editor is already setup such that if the remote shader compiler is not configured & Xcode is not available locally the shader-compiler will be invoked to generate text shaders.

For all Metal platforms >= Metal v1.2 transform mul(a,b) into fma(a,b,0) to prevent the Apple compiler reordering operations differently between the base & depth passes which results in variance in the position output.
For iOS disable fast-math when the vertex-shader uses World-Position-Offset because there are additional problems on the iOS shader compiler that result in position variance even with the above fix - WPO performance will suffer but I don't have any alternatives.

Fix for crash when creating a new media texture (AppleIntelHD5000GraphicsMTLDriver!SamplerStage::bindSamplerToTexture()). Missing texture resource for binding. Old InitDynamicRHI() code has been refactored out into seperate functions which leaves us on Mac with a NULL resource initially after creation which Metal doesn't like. This fix puts InitDynamicRHI down the default setup/clear path which inits default resources - I don't think we should use a global dummy in this instance as this is a render target.

Added LightmapType to PrimitiveComponent
* ForceVolumetric allows forcing static geometry to use Volumetric Lightmaps, which can be useful on instanced foliage where seams are prevalent. Lightmass internal caching still requires lightmap UVs and reasonable lightmap resolution.
* ForceSurface replaces bLightAsIfStatic
Improvements to Volumetric Lightmap quality needed for static geometry
* Stationary light shadowing is now dilated inside geometry
* Now doing two dilation passes since samples near geometry see inside due to ray start bias
* Refinement around geometry uses an expanded cell bounds when the geometry is going to use Volumetric Lightmaps, since cross-resolution stitching causes leaking
Lightmass debug primitives are now tied to a swarm task instead of global - allows debugging of Volumetric Lightmap tasks

Implement two components for MTLPP, an IMP cache for Objective-C selector implementations & an interposition framework for those same selectors:
- imp_SelectorCache & friends provide the IMP caching for each of the Metal protocols which constitute most of the API, so far I've not covered the Metal classes used for the various descriptor/initializer types. Each type has its own IMPTable which caches the selector's implementation pointer and provides the mechanism to hook that implementation. As Objective-C is runtime dynamic this look up must be performed on the actual Class value returned by an object at runtime - you can't do this at compile time. Even things like NSString which appear compile-time static are really not as NSString is an alias for a class-cluster (NSString, NSMutableString, __NSInlineString and more).
- The interpose directory contains MTI* files which are the framework for interposing all the functions in Metal's runtime API - I deliberately omit the descriptor classes & read-only functions as there's no benefit to interposing them - which I can build off to create a trace tool or a superior validation layer. Right now this is Mac only as there'll be some problems to solve for iOS/tvOS due to difference in linking requirements - not insurmountable.
- Rebuild MTLPP's implementation of the C++ wrapper classes around the IMPTable's - this means we avoid all the objc_msgSend overhead for all the classes and functions whose implementations are cached. Right now the IMPTable is going to incur a look-up for all non-copy/move constructors which is suboptimal - ideally the Metal IMPTables would be cached in the Device object as they will be consistent within a single Device.
- Sort out the MTLPP availability logic - it now exports the availability warnings to the caller and internally just blithely assumes it may call the functions, the caller is responsible for ensuring that calls are made only on appropriate devices & OSes. This reduces MTLPP complexity and better fits how MetalRHI works.
- Fix a number of retain/release bugs that were lying dormant in MTLPP but exposed by the switch to IMPTables.
- Add tvOS support.
Next up, put this into MetalRHI and start fixing all the fallout.

Volumetric Lightmap no longer refines around static translucent geometry - saves 5Mb in Monolith
Reworked brick culling by error mechanism. Now compares error to interpolated parent lighting instead of the brick average - prevents dropping constant value bricks which are near a wall and cause leaking due to parent interpolation after being culled.

Track whether the Metal shader uses the discard_fragment function as when this is used but without any other outputs we know we need to bind at least one render-target or a depth-stencil surface but we don't know which.

Added LightmapType to PrimitiveComponent
* ForceVolumetric allows forcing static geometry to use Volumetric Lightmaps, which can be useful on instanced foliage where seams are prevalent. Lightmass internal caching still requires lightmap UVs and reasonable lightmap resolution.
* ForceSurface replaces bLightAsIfStatic
Improvements to Volumetric Lightmap quality needed for static geometry
* Stationary light shadowing is now dilated inside geometry
* Now doing two dilation passes since samples near geometry see inside due to ray start bias
* Refinement around geometry uses an expanded cell bounds when the geometry is going to use Volumetric Lightmaps, since cross-resolution stitching causes leaking
Lightmass debug primitives are now tied to a swarm task instead of global - allows debugging of Volumetric Lightmap tasks

Change 3794627 by Mark.Satterthwaite
Implement two components for MTLPP, an IMP cache for Objective-C selector implementations & an interposition framework for those same selectors:
- imp_SelectorCache & friends provide the IMP caching for each of the Metal protocols which constitute most of the API, so far I've not covered the Metal classes used for the various descriptor/initializer types. Each type has its own IMPTable which caches the selector's implementation pointer and provides the mechanism to hook that implementation. As Objective-C is runtime dynamic this look up must be performed on the actual Class value returned by an object at runtime - you can't do this at compile time. Even things like NSString which appear compile-time static are really not as NSString is an alias for a class-cluster (NSString, NSMutableString, __NSInlineString and more).
- The interpose directory contains MTI* files which are the framework for interposing all the functions in Metal's runtime API - I deliberately omit the descriptor classes & read-only functions as there's no benefit to interposing them - which I can build off to create a trace tool or a superior validation layer. Right now this is Mac only as there'll be some problems to solve for iOS/tvOS due to difference in linking requirements - not insurmountable.
- Rebuild MTLPP's implementation of the C++ wrapper classes around the IMPTable's - this means we avoid all the objc_msgSend overhead for all the classes and functions whose implementations are cached. Right now the IMPTable is going to incur a look-up for all non-copy/move constructors which is suboptimal - ideally the Metal IMPTables would be cached in the Device object as they will be consistent within a single Device.
- Sort out the MTLPP availability logic - it now exports the availability warnings to the caller and internally just blithely assumes it may call the functions, the caller is responsible for ensuring that calls are made only on appropriate devices & OSes. This reduces MTLPP complexity and better fits how MetalRHI works.
- Fix a number of retain/release bugs that were lying dormant in MTLPP but exposed by the switch to IMPTables.
- Add tvOS support.
Next up, put this into MetalRHI and start fixing all the fallout.

Change 3764316 by Daniel.Wright
Added AVolumetricLightmapDensityVolume - gives local control over Volumetric Lightmap density. Dropping the top mip outside of the play area in Monolith saves 20Mb (35Mb original).
Volumetric Lightmap no longer refines around static translucent geometry - saves 5Mb in Monolith
Reworked brick culling by error mechanism. Now compares error to interpolated parent lighting instead of the brick average - prevents dropping constant value bricks which are near a wall and cause leaking due to parent interpolation after being culled.

Shader compiling memory optimizations
* Editor memory: Sharing uniform buffer includes and GeneratedInstancedStereo.ush per FShaderType (was previously duplicated per FShader job)
* SCW input size: Sharing uniform buffer includes and SharedEnvironment per batch
* 7.6Gb of shader job inputs in memory -> .5Gb (13x less) when doing a full shader compile of Paragon Editor
* 13.8Gb written into worker input files -> 2.9Gb (4.7x less). Global shaders are never batched when sent to SCW so unoptimized by these changes.

MetalShaderFormat will no longer fallback to text shaders when you ask it to compile to bytecode but the bytecode compiler is not available (either locally or remotely) - this ensures that the DDC can't be poisoned by incorrectly configured clients. The Editor is already setup such that if the remote shader compiler is not configured & Xcode is not available locally the shader-compiler will be invoked to generate text shaders.

Change 3769703 by Mark.Satterthwaite
For all Metal platforms >= Metal v1.2 transform mul(a,b) into fma(a,b,0) to prevent the Apple compiler reordering operations differently between the base & depth passes which results in variance in the position output.
For iOS disable fast-math when the vertex-shader uses World-Position-Offset because there are additional problems on the iOS shader compiler that result in position variance even with the above fix - WPO performance will suffer but I don't have any alternatives.
Remove the depth-offset hack from the depth-only vertex shader again.

Change 3770517 by Richard.Wallis
Fix for crash when creating a new media texture (AppleIntelHD5000GraphicsMTLDriver!SamplerStage::bindSamplerToTexture()). Missing texture resource for binding. Old InitDynamicRHI() code has been refactored out into seperate functions which leaves us on Mac with a NULL resource initially after creation which Metal doesn't like. This fix puts InitDynamicRHI down the default setup/clear path which inits default resources - I don't think we should use a global dummy in this instance as this is a render target.
#jira UE-51940

Change 3791886 by Daniel.Wright
Added LightmapType to PrimitiveComponent
* ForceVolumetric allows forcing static geometry to use Volumetric Lightmaps, which can be useful on instanced foliage where seams are prevalent. Lightmass internal caching still requires lightmap UVs and reasonable lightmap resolution.
* ForceSurface replaces bLightAsIfStatic
Improvements to Volumetric Lightmap quality needed for static geometry
* Stationary light shadowing is now dilated inside geometry
* Now doing two dilation passes since samples near geometry see inside due to ray start bias
* Refinement around geometry uses an expanded cell bounds when the geometry is going to use Volumetric Lightmaps, since cross-resolution stitching causes leaking
Lightmass debug primitives are now tied to a swarm task instead of global - allows debugging of Volumetric Lightmap tasks

Change 3794627 by Mark.Satterthwaite
Implement two components for MTLPP, an IMP cache for Objective-C selector implementations & an interposition framework for those same selectors:
- imp_SelectorCache & friends provide the IMP caching for each of the Metal protocols which constitute most of the API, so far I've not covered the Metal classes used for the various descriptor/initializer types. Each type has its own IMPTable which caches the selector's implementation pointer and provides the mechanism to hook that implementation. As Objective-C is runtime dynamic this look up must be performed on the actual Class value returned by an object at runtime - you can't do this at compile time. Even things like NSString which appear compile-time static are really not as NSString is an alias for a class-cluster (NSString, NSMutableString, __NSInlineString and more).
- The interpose directory contains MTI* files which are the framework for interposing all the functions in Metal's runtime API - I deliberately omit the descriptor classes & read-only functions as there's no benefit to interposing them - which I can build off to create a trace tool or a superior validation layer. Right now this is Mac only as there'll be some problems to solve for iOS/tvOS due to difference in linking requirements - not insurmountable.
- Rebuild MTLPP's implementation of the C++ wrapper classes around the IMPTable's - this means we avoid all the objc_msgSend overhead for all the classes and functions whose implementations are cached. Right now the IMPTable is going to incur a look-up for all non-copy/move constructors which is suboptimal - ideally the Metal IMPTables would be cached in the Device object as they will be consistent within a single Device.
- Sort out the MTLPP availability logic - it now exports the availability warnings to the caller and internally just blithely assumes it may call the functions, the caller is responsible for ensuring that calls are made only on appropriate devices & OSes. This reduces MTLPP complexity and better fits how MetalRHI works.
- Fix a number of retain/release bugs that were lying dormant in MTLPP but exposed by the switch to IMPTables.
- Add tvOS support.
Next up, put this into MetalRHI and start fixing all the fallout.

Allow ControlPointPatch lists to flow through MetalRHI as it was setup to handle this transparently - the VSHS compute shader will convert them to triangles to draw. Report the same warning as in the pipeline creation stage as this hasn't been formally validated.
#jira UE-52454
Change 3764316 by Daniel.Wright
Added AVolumetricLightmapDensityVolume - gives local control over Volumetric Lightmap density. Dropping the top mip outside of the play area in Monolith saves 20Mb (35Mb original).
Volumetric Lightmap no longer refines around static translucent geometry - saves 5Mb in Monolith
Reworked brick culling by error mechanism. Now compares error to interpolated parent lighting instead of the brick average - prevents dropping constant value bricks which are near a wall and cause leaking due to parent interpolation after being culled.

Shader compiling memory optimizations
* Editor memory: Sharing uniform buffer includes and GeneratedInstancedStereo.ush per FShaderType (was previously duplicated per FShader job)
* SCW input size: Sharing uniform buffer includes and SharedEnvironment per batch
* 7.6Gb of shader job inputs in memory -> .5Gb (13x less) when doing a full shader compile of Paragon Editor
* 13.8Gb written into worker input files -> 2.9Gb (4.7x less). Global shaders are never batched when sent to SCW so unoptimized by these changes.

MetalShaderFormat will no longer fallback to text shaders when you ask it to compile to bytecode but the bytecode compiler is not available (either locally or remotely) - this ensures that the DDC can't be poisoned by incorrectly configured clients. The Editor is already setup such that if the remote shader compiler is not configured & Xcode is not available locally the shader-compiler will be invoked to generate text shaders.

Change 3769703 by Mark.Satterthwaite
For all Metal platforms >= Metal v1.2 transform mul(a,b) into fma(a,b,0) to prevent the Apple compiler reordering operations differently between the base & depth passes which results in variance in the position output.
For iOS disable fast-math when the vertex-shader uses World-Position-Offset because there are additional problems on the iOS shader compiler that result in position variance even with the above fix - WPO performance will suffer but I don't have any alternatives.
Remove the depth-offset hack from the depth-only vertex shader again.

Fix for crash when creating a new media texture (AppleIntelHD5000GraphicsMTLDriver!SamplerStage::bindSamplerToTexture()). Missing texture resource for binding. Old InitDynamicRHI() code has been refactored out into seperate functions which leaves us on Mac with a NULL resource initially after creation which Metal doesn't like. This fix puts InitDynamicRHI down the default setup/clear path which inits default resources - I don't think we should use a global dummy in this instance as this is a render target.

Fix text-shader compilation on iOS 10 - maybe iOS 9 too (untested!).
We need our own make_scalar type-trait template for ue4_stdlib.metal so that we still compile with older iOS runtime compilers and we can't use as_type to directly implement the packHalf2x16/unpackHalf2x16 intrinsics for these older runtime compilers either.

Track whether the Metal shader uses the discard_fragment function as when this is used but without any other outputs we know we need to bind at least one render-target or a depth-stencil surface but we don't know which.

UE5_MAIN: Multi-view-family scene renderer refactor, part 1. Major structural change to allow scene renderer to accept multiple view families, with otherwise negligible changes in internal behavior.
* Added "BeginRenderingViewFamilies" render interface call that accepts multiple view families. Original "BeginRenderingViewFamily" falls through to this.
* FSceneRenderer modified to include an array of view families, plus an active view family and the Views for that family.
* Swap ViewFamily to ActiveViewFamily.
* Swap Views array from TArray<FViewInfo> to TArrayView<FViewInfo>, including where the Views array is passed to functions.
* FSceneRenderer iterates over the view families, rendering each one at a time, as separate render graph executions.
* Some frame setup and cleanup logic outside the render graph runs once.
* Moved stateful FSceneRenderer members to FViewFamilyInfo, to preserve existing one-at-a-time view family rendering behavior.
* Display Cluster (Virtual Production) uses new API.
Next step will push everything into one render graph, which requires handling per-family external resources and cleaning up singletons (like FSceneTextures and FSceneTexturesConfig). Once that's done, we'll be in a position to further interleave rendering, properly handle once per frame work, and solve artifacts in various systems.

MIGRATING FIX @ Request
Off by 1 error on reflection roughness calculation affecting 4.12. When I hoisted the max mip index i did a -1 on both sides(c++ & hlsl). This is the simplest hotfix. In 4.13 I'll remove the shader instruction and only do the "-1" in c++ this 1 less shader instruction.

Shadow depth refactor
* Shadow setup and render target allocation now happens in InitViews, and shadow depth rendering happens at one spot in the frame
* This provides control over where shadow depths are rendered for things like async compute, and allows easy atlasing of shadowmaps for forward shading
* The 33Mb of shadow depth buffers in FSceneRenderTargets has been removed, and shadow depth buffers are now allocated as needed
* A large amount of duplicated code to handle each shadow type has been combined
* Cleaner parallel rendering: no more view hacking for the shadow depth pass, no more shadow depths in the middle of translucency
* 'vis ShadowDepthAtlas' or 'vis WholeSceneShadowMap' must now be used to visualize the shadow depth textures

Cached shadowmaps for whole scene point and spot light shadows
* Controlled by 'r.Shadow.CacheWholeSceneShadows', defaults to enabled (7ms -> 1.5ms of shadow depths on Titan for ~20 lights)
* Primitives with Static or Stationary mobility have their depths cached, as long as the light is not moving
* Primitives with Movable mobility or using World Position Offset in their materials will not have their depths cached
* Cached shadowmaps are copied each frame and then movable primitive depths composited
* Fast paths exist for when there were no static primitives (skip cached shadowmap) or movable primitives (project directly from cached shadowmap)
* 'r.Shadow.CacheWPOPrimitives' controls whether materials using WPO can be cached (default is off for correctness)
* 'r.Shadow.CachedShadowsCastFromMovablePrimitives' can be used to force off all support for movable primitives, skipping the shadowmap copies (1.5ms -> 0ms of shadow depths for ~20 lights)

Add a per-object shadow setting for directional lights (r.Shadow.PerObjectDirectionalDepthBias), which is independent of the CSM setting. Often a smaller bias is desirable on per-object shadows, where detailed self-shadowing is needed.
This change also makes the CSM naming consistent with what the setting actually does (the old setting was named r.shadow.csm, although it affects per-object shadows as well as CSMs).

UE5_MAIN: Multi-view-family scene renderer refactor, part 1. Major structural change to allow scene renderer to accept multiple view families, with otherwise negligible changes in internal behavior.
* Added "BeginRenderingViewFamilies" render interface call that accepts multiple view families. Original "BeginRenderingViewFamily" falls through to this.
* FSceneRenderer modified to include an array of view families, plus an active view family and the Views for that family.
* Swap ViewFamily to ActiveViewFamily.
* Swap Views array from TArray<FViewInfo> to TArrayView<FViewInfo>, including where the Views array is passed to functions.
* FSceneRenderer iterates over the view families, rendering each one at a time, as separate render graph executions.
* Some frame setup and cleanup logic outside the render graph runs once.
* Moved stateful FSceneRenderer members to FViewFamilyInfo, to preserve existing one-at-a-time view family rendering behavior.
* Display Cluster (Virtual Production) uses new API.
Next step will push everything into one render graph, which requires handling per-family external resources and cleaning up singletons (like FSceneTextures and FSceneTexturesConfig). Once that's done, we'll be in a position to further interleave rendering, properly handle once per frame work, and solve artifacts in various systems.

Sparse, narrow band, streamed Mesh Signed Distance Fields
* SDFs are now generated, allocated from the atlas and uploaded in 8^3 bricks (7^3 unique data, half voxel padding).
* Tracing must load the brick index from the indirection table, and only bricks near the surface are stored
* 3 mips are now generated, with the lowest resolution always loaded and the other 2 streamed
* SDFs are now G8 narrow band. Lower resolution mips must be traversed when querying distance to nearest surface far away from the surface
* The Distance Field Brick Atlas is now stored for each FScene and dynamically resized based on needs with a GPU memcopy
* Brick atlas uses a 1d pooled allocator which has no fragmentation and greatly reduces packing waste over the 3d allocator
* Added new indirection for Distance Field Asset data, so that only a single entry needs to be updated when a mip is streamed in or out in scenes with millions of instances
* Compute shaders operating on distance field instances generate streaming requests, which are async read back to CPU, turned into IO requests, which are polled and when complete uploaded to atlases
* Any mesh instance inside the Global SDF extent (200m) requests mip1, and at 50m requests mip2
* Now using a batched compute scatter to upload to the distance field atlas instead of RHIUpdateTexture3d, to bypass alignment restrictions and per-upload overhead
* Distance Field streaming uses an async task to move Memcpy and IO request overhead off of the Rendering Thread
* Distance Field Visualization now computes a normal from the SDF gradient and does simple lighting to better visualize the scene representation
* Increased r.DistanceFields.MaxPerMeshResolution from 128 to 512, to better represent large objects
* Mesh SDF generation now uses an Embree point query to calculate closest unsigned distance, and then a much smaller set of rays to count backfaces for negative region determination, for a 11x speedup
* Upgraded mesh utilities to Embree 3.12.2 to get point queries
* Fixed wrong transform used for SDF normals in Lumen, causing non-uniformly scaled meshes to have incorrect Surface Cache interpolation
* Fixed Static Mesh materials not getting PostLoaded before SDF build, causing their blend modes to be wrong for the build, which corrupts the DDC. Also included those blend modes in the DDC key.

UE5_MAIN: Multi-view-family scene renderer refactor, part 2. Move FSceneTextures singleton out of RDG blackboard and FSceneTexturesConfig global variable singleton, into FViewFamilyInfo. This is necessary to allow multiple view families to render in a single render graph and a single scene renderer call.
* Existing calls to CreateSceneTextureShaderParameters and similar functions use "GetSceneTexturesChecked", which allows for the possibility that they are reached in a code path where scene textures haven't been initialized, and nullptr is returned instead of asserting. The shader parameter setup functions then fill in dummy defaults for that case. The goal was to precisely match the original behavior, which queried the RDG blackboard, and gracefully handled null if scene textures weren't there. This definitely appears to occur in FNiagaraGpuComputeDispatch::ProcessPendingTicksFlush, which can be called with a dummy scene with no scene textures. In the future, I may change this so dummy defaults are filled in for FSceneTextures at construction time, so the structure is never in an uninitialized state, but I would like to set up a test case for the Niagara code path before doing that, and the checks aren't harmful in the meantime.
* I marked as deprecated global functions which query values from FSceneTexturesConfig, but they'll still work with the caveat that if you use multi-view-family rendering, the results will be indeterminate (whatever view family rendered last). There was only one case outside the scene renderer that accessed the globals (depth clear value), which I removed, noting that there is nowhere in the code where we modify the depth clear value from its global default. I would like to permanently deprecate or remove these at some point. Display Cluster is the only code that's currently using the multi-view-family code path, and as a new (still incomplete) feature, third party code can't be using it, and won't be affected.

Sparse, narrow band, streamed Mesh Signed Distance Fields
* SDFs are now generated, allocated from the atlas and uploaded in 8^3 bricks (7^3 unique data, half voxel padding).
* Tracing must load the brick index from the indirection table, and only bricks near the surface are stored
* 3 mips are now generated, with the lowest resolution always loaded and the other 2 streamed
* SDFs are now G8 narrow band. Lower resolution mips must be traversed when querying distance to nearest surface far away from the surface
* The Distance Field Brick Atlas is now stored for each FScene and dynamically resized based on needs with a GPU memcopy
* Brick atlas uses a 1d pooled allocator which has no fragmentation and greatly reduces packing waste over the 3d allocator
* Added new indirection for Distance Field Asset data, so that only a single entry needs to be updated when a mip is streamed in or out in scenes with millions of instances
* Compute shaders operating on distance field instances generate streaming requests, which are async read back to CPU, turned into IO requests, which are polled and when complete uploaded to atlases
* Any mesh instance inside the Global SDF extent (200m) requests mip1, and at 50m requests mip2
* Now using a batched compute scatter to upload to the distance field atlas instead of RHIUpdateTexture3d, to bypass alignment restrictions and per-upload overhead
* Distance Field streaming uses an async task to move Memcpy and IO request overhead off of the Rendering Thread
* Distance Field Visualization now computes a normal from the SDF gradient and does simple lighting to better visualize the scene representation
* Increased r.DistanceFields.MaxPerMeshResolution from 128 to 512, to better represent large objects
* Mesh SDF generation now uses an Embree point query to calculate closest unsigned distance, and then a much smaller set of rays to count backfaces for negative region determination, for a 11x speedup
* Upgraded mesh utilities to Embree 3.12.2 to get point queries
* Fixed wrong transform used for SDF normals in Lumen, causing non-uniformly scaled meshes to have incorrect Surface Cache interpolation
* Fixed Static Mesh materials not getting PostLoaded before SDF build, causing their blend modes to be wrong for the build, which corrupts the DDC. Also included those blend modes in the DDC key.

UE5_MAIN: Multi-view-family scene renderer refactor, part 2. Move FSceneTextures singleton out of RDG blackboard and FSceneTexturesConfig global variable singleton, into FViewFamilyInfo. This is necessary to allow multiple view families to render in a single render graph and a single scene renderer call.
* Existing calls to CreateSceneTextureShaderParameters and similar functions use "GetSceneTexturesChecked", which allows for the possibility that they are reached in a code path where scene textures haven't been initialized, and nullptr is returned instead of asserting. The shader parameter setup functions then fill in dummy defaults for that case. The goal was to precisely match the original behavior, which queried the RDG blackboard, and gracefully handled null if scene textures weren't there. This definitely appears to occur in FNiagaraGpuComputeDispatch::ProcessPendingTicksFlush, which can be called with a dummy scene with no scene textures. In the future, I may change this so dummy defaults are filled in for FSceneTextures at construction time, so the structure is never in an uninitialized state, but I would like to set up a test case for the Niagara code path before doing that, and the checks aren't harmful in the meantime.
* I marked as deprecated global functions which query values from FSceneTexturesConfig, but they'll still work with the caveat that if you use multi-view-family rendering, the results will be indeterminate (whatever view family rendered last). There was only one case outside the scene renderer that accessed the globals (depth clear value), which I removed, noting that there is nowhere in the code where we modify the depth clear value from its global default. I would like to permanently deprecate or remove these at some point. Display Cluster is the only code that's currently using the multi-view-family code path, and as a new (still incomplete) feature, third party code can't be using it, and won't be affected.

Also, switch a specialization of BlendTransform() from a function with a check to just a declaration so compiler will catch error instead of a runtime catch.

Simple threaded CSV Profiler
To capture:
- On the commandline, add -csvCaptureFrames=N to capture N frames from startup
- On the console, use csvprofile start, csvprofile stop or csvprofile frames=N to capture a fixed number of frames
- Instrument with CSV_SCOPED_STAT(statname), CSV_CUSTOM_STAT(statname,value).
CSV capture is enabled in all builds except shipping
- Please do not check in the instrumentation √ we don╞t want to pollute the engine with lots of additional instrumentation. We may add some minimal level of instrumentation at some point

Fix editor crash (NULL dereference of ScreenSpaceShadowTexture) when moving the camera around in tm-shadermodels, probably fallout from the VRAM aliasing merge. Not sure if this is the correct fix, but it prevents the crash for now
Change 3451601 on 2017/05/22 by Josh.Adams
- Track idle time from MaxTickRate, so that stat unit is accurate on Game: thread

Change 3475298 on 2017/06/06 by Luke.Thatcher
[CONSOLE] [!] Fix RHITransitionResources crash with more than 16 textures.
- Old command had a fixed sized array of 16 textures that would overflow.
- New command allocates an array of texture pointers inline in the command list, so any number is supported.
