1) Allows motion blur to output half and/or quarter res based on what the following passes needs. This avoids adding downsampling passes after
2) Runs FFT bloom on async compute to overlap with all the histogram exposure and local pre exposure stuf
3) Fixes a bug where r.Bloom.HalfResolutionFFT resolution was also dependent r.PostProcessing.QuarterResolutionDownsample
Frosty configurations:
1) Configures to use simple 2x2 dowsampling in post processing to be able to use the fast motion blur code path
2) Configures histogram exposure and local exposure to quarter res.

1) Motionblur have tile classification to improve VGPR pressure on fast motion blur gathering tiles
2) Motionblur tile classification can lower the gathering resolution to half res with r.MotionBlur.HalfResGather=1 on part of the screen with large motion vectors to reduce VALU costs under large movements, but still can compose with full res scene color without round trip to main memory to avoid adding memory bandwidth costs
3) TSR output a half res scene color in Mip1 so motion blur can dynamically sample half res under largement movements with r.MotionBlur.HalfResInput=1 to save memory bandwidth in the motion blur convolution
4) Number of direction samples becomes dynamic (and clamped to exisiting motion blur quality) based on length of motion vector to saves VALU with slow pixel velocities
5) Motion blur automatically avoid sampling full res center if the blur kernel completly occlude its to completly stop fetching full res to save memory bandwidth cost under large motions
Drops motion blur costs from 753us to 339us of motion blur costs + 40us additional cost in TSR to output half res in sandbox under movements.
And saves an average 0.3ms in the entire chase gameplay sequence.

[CL 10870549 by ryan durand in Main branch]
- Fixed regression with checkerboard rendering and odd render target sizes. The passes were not guaranteed to produce
a UV coordinate centered on an input pixel for each output pixel.
- Fixed regression when visualizing SSS at native screen resolution (i.e. no secondary spatial upsampling). The issue was that
the rendering composition graph injects the backbuffer as the last texture in the post processing pipeline. If visualize SSS was
the last pass, it would overwrite the backbuffer texture, causing visual artifacts.
- Minor performance improvement for multi-view SSS. All views in a split-screen scenario now render into the same output target (instead
of ping ponging between multiple targets) and only views not utilizing SSS get copied from the source target. The is reduces the worst case
of viewport copied from O(N^2) to O(N); if all viewports use SSS (common in VR), then no copies are performed.
- Removed FScreenPassTexture in favor of more selective pairing of FRDGTextureRef and FScreenPassTextureViewport. This reduces
some boilerplate and extraneous memory copying. Motion blur passes now compute their viewport shader parameters once.

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.

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.

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 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-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 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 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.

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.

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

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.

Fix for Mac editor session no longer accurately tracking Mouse location after moving between Desktops in Mission Control on 10.12.6. 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.

Change 3710454 by Mark.Satterthwaite
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.

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

Updated items from original shelved version by Mark Satt:
- Added MetalBackend.cpp to change main function string to have an initial crc + code length zero's
**Description below taken from Mark Satt's original verison of this in CL3343280**
Updated for Dev-Rendering's PSOs & integrates Richard's work on RHI shader libraries.
Replace the FShaderCache's cook-time binary shader cache with Dmitriy Dyomin's standalone FShaderCodeLibrary that saves all shader byte-code arrays to files named by the FSHAHash. This de-duplicates shaders so we only ever store the byte code once. Includes optional support for generating a platform specific library file - which Metal implements to provide a single Metal library. The platform-native implementation can perform more de-duplication and in the case of Metal has lower file overheads and will compress more efficiently.
- All of the support code for the FShaderCache's cook caching is gone, which affects all platforms. The FShaderCodeLibrary is currently supported by Cook-By-The-Book but can be used with iterate or child cookers - only DLC cooking requires further work.
- With further modifications it should be possible to support Cook-on-the-Fly as well (output directories would be needed in FShaderCodeLibrary::InitForCooking) and the file-access pattern should be changed to use async. IO so that Material loading is not considered complete until all required byte-code arrays are loaded into the FShaderCodeLibrary.
- For Metal archiving shaders this way will compile with debug information and the FShaderCodeLibrary, with some help from extensions to IShaderFormat, will save the debug information out into separate files during cooking - these can then be used to debug the game without having to locally recompile, recook & repackage but the shipped byte-code is stripped. Global shader caches are also subject to de-duplication in the library in order to support Metal's shader stripping.
- File Move operations need to respect the 'Replace' flag - for FShaderCodeLibrary to work we need Move to be atomic.
- This bumps the object version and will cause all content to recook.
- Native library support is optional - only Metal currently implements one, but so could Vulkan and D3D12. For Metal the big advantages are further de-duplication where different materials generate the same MetalSL text but a different FSHAHash, that the single Metal library has lower overhead and that as a single file it all compresses far better (esp. with LZMA - 5x smaller).
Change 3367854 on 2017/03/28 by Mark.Satterthwaite
Don't track or record draw call resources for non-OpenGL shader platforms in the shader-cache as it is unnecessary and makes it slower on the CPU than it needs to be.

Change 3372436 on 2017/03/30 by Uriel.Doyon
Added flags in UPrimitiveComponent to keep track of its state in the streaming manager.
This allows to avoid unnecessary callback and processing in begin destroy reattach and being destroy logic.
Removed the limitation of only processing UMeshComponent when handling spawed primitive.
This releases the level manager from having to manage dynamic primitives.
This improves performance by not having to manage dynamic references in the level manager.
Primitives managed as dynamic now have a callback when ever their proxy is udpated, handling
many cases automatically where previously a manual callback to notify would have been required.
Fixed an issue where primitives with no reference to streaming textures would loose they dynamic state
because of lack of references in the streamer.

FShaderCache Parallel-Context-Aware Merged with FShaderCache Single Library.

- This was done before Engine PSO were in so this now needs a refector in the recording and playback on pipeline states instead an emulate PSO in OpenGL Driver.
- Remove FShaderCacheState and replace the logic with FGraphicsPipelineStateInitializer which should be able to record from the RHI current pipeline state
- This would reduce the Locking required as it's naturally per thread/context and only the final record would need a lock

Change 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.

* Materials using DBuffer blend modes will fail to compile when the DBuffer project setting is disabled, instead of just being invisible

Added r.AOSpecularOcclusionMode, which determines how specular should be occluded by DFAO
0: Apply non-directional AO to specular.
1: (default) Intersect the reflection cone with the unoccluded cone produced by DFAO. This gives more accurate occlusion than 0, but can bring out DFAO sampling artifacts.
2: (experimental) Cone trace through distance fields along the reflection vector. Costs about the same as DFAO again because more cone tracing is done, but produces more accurate occlusion.

My earlier fix for UE-27513 overlooked various internal details that meant it wouldn't restore state correctly, would fail validation and could crash in a new place.

Reimplement Metal object lifetime tracking as stats in the stat-group, though the old system is maintained as a debug-only tool that could (and probably should) be extended to track over/under-release bugs. Currently the texture count will be distorted by texture SRVs so will need improvement but other stats should be reliable. In order to properly report the number of buffers the TResourcePool policy class must now define a FreeResource function, so I've added them to the appropriate places too.
Change 2900853 on 2016/03/09 by Mark.Satterthwaite
Optimise away empty encoders that don't perform a clear operation on AMD & Intel, but not Nvidia or non-Mac Metal devices. This should slightly improve performance.
Change 2900927 on 2016/03/09 by Mark.Satterthwaite
Implemented operation threshold submission of Metal command buffers to keep the GPU busier and not just idle waiting for the CPU. Whenever rhi.Metal.CommandBufferCommitThreshold is set to a value >0 and the current command buffer has >= draw/dispatch operations outstanding then the command-buffer will be committed at the next encoder boundary. The default value is 100 operations which is currently arbitrary and the feature can be disabled by setting the value to <= 0 in which case only explicit submissions will occur as previously.
Change 2901310 on 2016/03/09 by Mark.Satterthwaite
Change OneColor clear shader setup so that it works with parallel encoding in Metal.
Change 2903002 on 2016/03/10 by Mark.Satterthwaite
Instantiate the OneColor shaders once in Metal.
Change 2903274 on 2016/03/10 by Mark.Satterthwaite
Remove more unnecessary parallel execution stalls from MetalRHI.
Change 2903402 on 2016/03/10 by Mark.Satterthwaite
Implement Metal support for index buffer SRVs.
Change 2903419 on 2016/03/10 by Mark.Satterthwaite
Always use Managed memory on Mac Metal for buffers.
Change 2905206 on 2016/03/11 by Mark.Satterthwaite
Worked around UE-27818 "ElementalDemo Causes Invalid Rendering on AMD GPUs" - recent changes to allow mesh particles to write to velocity leave a texture-buffer unbound & then use a uniform value & an if-branch to guard against access but AMD's Mac GL driver notices that the buffer is referenced in the shader but not bound & promptly tries to fallback to Apple's S/W renderer regardless of what the uniform value is. That's legal behaviour for an OpenGL implementation so the C++ code has been changed to allocate and write the current transforms into the buffer for OpenGL when they wouldn't otherwise be provided. This is sufficient to avoid the problem without affecting any other API.

Change 2908203 on 2016/03/14 by Michael.Trepka
Merging //UE4/Dev-Main to Dev-Platform (//UE4/Dev-Platform). Everything but SSF lib.
Change 2908553 on 2016/03/14 by Mark.Satterthwaite
Force a submit & wait in Metal when contexts are being destroyed to prevent kernel panics in drivers which continue to process the now abandoned command-queue and encounter invalid resources (because we destroy them on shutdown).
Change 2908595 on 2016/03/14 by Michael.Trepka
Fixed iOS compile error in MetalUniformBuffer.cpp

Change 2910106 on 2016/03/15 by Mark.Satterthwaite
Use a dispatch_semaphore not an FEvent for Metal free-list synchronisation as the dispatch_worker threads can't be properly setup for FStats and this causes problems.
Change 2910107 on 2016/03/15 by Mark.Satterthwaite
Fix Metal reporting of GPU memory through the RHI as it is in bytes, not MB.
Change 2910138 on 2016/03/15 by Mark.Satterthwaite
Properly retain/release dispatch_semaphore for Metal command buffer completion block & allow uniform buffer creation on parallel encoding thread.

Change 2880344 on 2016/02/24 by Daniel.Wright
Added the ability to apply DFAO to static indirect lighting, controlled by r.AOApplyToStaticIndirect
* Lightmaps, stationary skylight and reflection captures are all affected
* Specular occlusion on reflection captures requires a fair amount of tweaking of r.SkySpecularOcclusionStrength, MinOcclusion and MaxOcclusionDistance for good quality
* For now, a movable skylight with low intensity (.0001) must be placed to control MaxOcclusionDistance and MinOcclusion
