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

#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.

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.

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 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

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

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.
#jira UE-46604

Reinvalidates shaders with shader permutations.
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 3792884 by Marcus.Wassmer

Added color grading control BlueCorrection to correct for artifacts with "electric" blues due to the ACEScg color space. Bright blue desaturates instead of going to violet.
Added color grading control ExpandGamut which expands bright saturated colors outside the sRGB gamut to fake wide gamut rendering.
ACES changes.

Resaves uassets that were modified between 3789648 and 3794285
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 3794631 by Mark.Satterthwaite
Missed updating mtlpp's build.cs for TVOS.

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

Move audio processing over to audio bus tap. Currently on Mac Media audio playback uses OS media player mixer rather than Engine as existing implemtation, using AVAssetReader, now suffers from poor performance with new Media Framework. This audio tap version replaces that asset reader implementation but also suffers from bad quality audio hence is still disabled at the top of AvfMediaTracks.cpp.
Original Code Review Description:
Convert Mac to Play audio through the engine MediaFramework API rather than using AVMediaPlayer. This is the Mac implementation only - this should work ok on iOS but unable to test due to missing audio type implementation (throws error "Init Buffer on unsupported sound type name = Synth type = 5"), as such is only enabled for Mac. There maybe some extra tweaks required for iOS on app backgrounding etc if this feature is enabled.
- Stuttering Audio Performace issue investiagation: Re-Tested this implementation against [now fixed] current Mac implementation which was working fine last year and that implementation now has the same audio output quality (performance) issues as this one. Basic investigation seems to point to somewhere in the engine audio handing. When poor audio is heard the FMediaAudioResampler::Generate() function is dequeing an IMediaAudioSample sample buffer and the audio sample queue usually has 50-100 of these IMediaAudioSample buffers waiting in the queue. I think the AvfMedia playback system is providing the sample buffers in good time but they are not getting consumed "fast" enough. This under consuming also occurs if I force the Core Audio - Audio Unit mixer to use 48000 samples/sec.

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

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

Lightmass correctness fixes
* After these changes, point, spot, directional and sky lights closely match reference renderer Mitsuba after light unit conversions
* Photon density trimming intended for direct photons was affecting indirect photons as well. This caused high noise for point / spot lights with a large attenuation radius. Indirect photon density even for small lights is 5x with this change, which improves 2nd bounce quality.
* Removed legacy fudge factor on point / spot light photon energy
* Spotlights no longer emit based on indirect photon paths. Fixes excessive photon energy from spot lights as they were emitting outside of the cone.
* Fixed photons computing one more bounce than requested.
* Added an option to use the Radiosity solver for all multibounce, replacing photons. Useful as a reference but generally too much noise indoors.

Change 3756983 by Mark.Satterthwaite
Prevent different versions of metal_stdlib/ue4_stdlib from causing shader compilation failures due to a time-stamp mismatch between the local file & the PCH. This can happen when working with Xcode Beta releases that change the modification date, but not the content or compiler version, amongst other possibilities.

Render thread dynamic resolution & TAA upsample.
Merging //Tasks/UE4/Dev-DynamicRes/...@3694528 to //UE4/Dev-Rendering/...
New features breakdown:
- TAA upsample compute shader that accepts screen percentage from 50% to 200%, with a faster shader permutation for consoles;
- Material no longer have to deal with BufferUV, and post process material after TAA upsample can sample any scene buffer seamlessly;
- Material texture per view mip bias to produce sharper images with TAA upsample;
- Render thread dynamic resolution heuristic is fully plugable by game code (for VR plugin specific heuristics);
- Dynamic resolution in PIE and game builds;
- Busy time queries in the RHI to be implemented on the different platforms so that the dynamic resolution heuristic can exactly associate GPU frame times with screen percentages in its history;
- Game user settings to enable/disable dynamic resolution;
- In editor viewport screen percentage config to previsualise and test content at different screen percentage.
Fixes:
- Various fixes for algorithms producing different outputs at different screen percentage.
- Various fixes for algorithms sampling outside view rects.
Refactors:
- TAA shader
- Moved some screen percentage specific members from FSceneView to FViewInfo for thread race bullet proofing.
Aknowledgements:
- VR plugins are broken
- DFAO still have some artifacts

- Disable texture streaming
- AScreenshotFunctionalTest now reads back from game viewport directly when taking screenshot
- AFunctionalUIScreenshotTest now render into a custom render target using FWidgetRenderer so that UI screenshot can be captured at fixed size
- Add a new class, AScreenshotFunctionalTestBase, that handles screenshot common functions. AScreenshotFunctionalTest and AFunctionalUIScreenshotTest now derive from it
