#lockdown Nick.Penwarden #rb none ========================== MAJOR FEATURES + CHANGES ========================== Change 3122543 on 2016/09/13 by Ben.Woodhouse Override HasOcclusion for Widget3DComponentProxy to detect if the material is has depth testing enabled. #jira UE-35878 Change 3122544 on 2016/09/13 by Ben.Woodhouse Shadow stencil optimisation with cvar (enabled by default) Avoids redundant clearing the stencil buffer for per-object and pre shadows by zeroing the stencil during testing, following discussion on UDN. This means we don't benefit from Hi Stencil on GCN for the shadow projection draw calls, but it's still faster in all the cases I could find, including for the player character where the bounding box is quite large. (Note: early stencil still works fine, according to PIX) Shadow projection GPU time profiling : Test map with 35 characters, stationary directional light - 4ms-2ms on XB1 - 2.5ms to 0.9ms on PC (r9-390X) - 3ms-2ms on PS4 Paragon PS4 (roughly 20% reduced - from ~0.39ms) Change 3122687 on 2016/09/13 by Rolando.Caloca DR - vk - Fix ES31 crash Change 3122691 on 2016/09/13 by Rolando.Caloca DR - vk - Fixes for SDK 1.0.26.0 Change 3122778 on 2016/09/13 by Rolando.Caloca DR - vk - Fix number of layers on barrier Change 3122921 on 2016/09/13 by Rolando.Caloca DR - vk - Fix ES3.1 Change 3122925 on 2016/09/13 by Ben.Woodhouse Fix sky lighting issue with skin and re-enable non-checkerboard lighting by default (fallout from lightaccumulator refactor) #jira UE-35904 Change 3123016 on 2016/09/13 by Chris.Bunner Fixed adaptive tessellation, broken by CL 3089208 refactor. #jira UE-35341 Change 3123079 on 2016/09/13 by Rolando.Caloca DR - vk - Force StoreOp store instead of DontCare everywhere (temporarily) Change 3123503 on 2016/09/13 by David.Hill #jira UE-25623 converted a check() to checkf() to include better diagnostic information. Change 3123617 on 2016/09/13 by Guillaume.Abadie Fixes artifact when the camera direction is almost parallel to a wide plane with SSR. #jira UE-35128 Change 3123743 on 2016/09/13 by Brian.Karis Separate mesh reduction interfaces for static and skeletal. Zero bad tangents from input mesh. Change 3125378 on 2016/09/14 by Arne.Schober DR - [UE-34481] - Extract all the State which is necessary to execute the DebugTextDrawingDelegate from the SceneProxy into its own Helpers to be drawn to the canvas later on. The issue was that the SceneProxys are only owned by the RT after their creation and the GT should avoid reading from or writing state to them. Change 3125527 on 2016/09/14 by Arne.Schober DR - [UE-34481] - Fix UT build and mac Change 3125741 on 2016/09/14 by Rolando.Caloca DR - Extra debug mode for tracking down SCW crashes (r.DumpSCWQueuedJobs=1) Change 3125763 on 2016/09/14 by Rolando.Caloca DR - vk - Added new Renderpass cache - Fix buffer barrier warning Change 3125769 on 2016/09/14 by Rolando.Caloca DR - Renamed cvar to r.DumpSCWQueuedJobs Change 3125771 on 2016/09/14 by Rolando.Caloca DR - Added support for SV_ClipDistance on GL3 & 4 Change 3125792 on 2016/09/14 by Arne.Schober DR - [UE-34481] - Fix Odin and PS4 Change 3125880 on 2016/09/14 by Arne.Schober DR - [UE-34481] - Fix Fortnite Change 3125968 on 2016/09/14 by Brian.Karis Removed comment Change 3126315 on 2016/09/15 by Ben.Woodhouse GPU profiler robustness - Change stat gathering update to handle multiple views and non-scenerenderer stats (such Slate) properly - Simplify gathering logic - Fix race condition where we could read back queries before they're submitted on the RHI thread. - Fix for movie player stat gathering - disable gathering outside of the main engine tick #jira UE-35975 Change 3126792 on 2016/09/15 by Rolando.Caloca DR - vk - Release render pass cache Change 3126804 on 2016/09/15 by Rolando.Caloca DR - vk - Fix UpdateTexture2D() #jira UE-34151 Change 3126884 on 2016/09/15 by Rolando.Caloca DR - vk - Compile fix Change 3126953 on 2016/09/15 by Rolando.Caloca DR - Enable GPU capture when running OpenGL under RenderDoc - Will also set the memory mode to non coherent so not to kill performance on RenderDoc Change 3126966 on 2016/09/15 by Rolando.Caloca DR - Allow cooking for Vulkan SM4 to help with packaging Change 3127082 on 2016/09/15 by Guillaume.Abadie Wraps up contact shadows for release fixing different artifacts and handling correctly their screen space length. #jira UE-35367, UE-33602, UE-33603, UE-33604 #review-3125887 @brian.karis Change 3127130 on 2016/09/15 by Mark.Satterthwaite Add overloads to as* functions in hlslcc - HLSL allows you to call these on variables of the same type, in which case it simply returns the existing value but we had only defined the float<->u/int conversions, so hlslcc added implicit casts that broke such cases (i.e. asuint(uint) -> floatBitsToUint(float(uint))). This change defines the missing overloads as returns with regular casts. #jira FORT-25869 #jira UE-34263 Change 3127475 on 2016/09/15 by Rolando.Caloca DR - vk - Debug dump Change 3128131 on 2016/09/16 by Ben.Woodhouse (Integrated from //UE4/Private-Partner-NREAL/...) Alpha output support for postprocess materials (optional via a parameter) Needed for end of frame compositing. Could be used to pass intermediate data from one blendable postprocess to another (e.g edge detection) Change 3128135 on 2016/09/16 by Ben.Woodhouse GPU profiler (PS4) - remove bubbles between commandlist submissions from query times Use r.ps4.AdjustRenderQueryTimestamps cvar to enable/disable (defaults to on) Also fixes some potential precision issues with unit GPU timing Change 3128247 on 2016/09/16 by Rolando.Caloca DR - vk - Cache framebuffers Change 3128593 on 2016/09/16 by Rolando.Caloca DR - vk - Fix for crash loading map #jira UE-36072 Change 3128759 on 2016/09/16 by Mark.Satterthwaite Back out changelist 3127130 - its causing a build failure in FPostProcessVelocityScatterVS because hlslcc is picking the wrong as_* overload. Change 3130236 on 2016/09/19 by Chris.Bunner Exposed full SceneCaptureComponent classes instead of select methods. #jira UE-35996 Change 3130388 on 2016/09/19 by Rolando.Caloca DR - Avoid crash when adding dynamic primitives #jira UE-35327 Change 3130393 on 2016/09/19 by Marc.Olano Improve vector noise tooltips & documentation Change 3130547 on 2016/09/19 by Ben.Woodhouse Fix for ensure fail when initializing point light shadowmaps. This came about because cubemap rendertargets always have Extents of (Resolution, 0). The Y component was implicitly used to determine if it was a cubemap, which is odd... The fix was to make the definition explicit via a flag and initialize both the X and Y parameters. I suspect the ensure started happening recently due to a more recent change, but fixing the underlying logic seems like the correct fix. #jira UE-35837 Change 3130578 on 2016/09/19 by Daniel.Wright Workaround OpenGL/NVidia bug with non-power-of-2 textures by disabling CSM atlassing if we're using OpenGL Change 3130682 on 2016/09/19 by Rolando.Caloca DR - Better fix for UE-35327 #jira UE-35327 Change 3130767 on 2016/09/19 by Uriel.Doyon Better handling of color array in VisualizeComplexity code to prevent assert. #jira UE-29332 Change 3130965 on 2016/09/19 by Arne.Schober DR - [UE-35679] - the crash was caused by the Resource of the UTexture being Null. And one of the Kismet Nodes calling a function on that resource. The solution was to disable that call from Kismet when only cooking. Change 3130967 on 2016/09/19 by Chris.Bunner Hid redundant texture sampler properties from texture object parameter. Hid redundant texture property input on texture parameter nodes. Fixed copy-paste error in expression texture parameter docs. #jira UE-32724 Change 3131118 on 2016/09/19 by Mark.Satterthwaite Second attempt - this time with the correct input types. Add overloads to as* functions in hlslcc - HLSL allows you to call these on variables of the same type, in which case it simply returns the existing value but we had only defined the float<->u/int conversions, so hlslcc added implicit casts that broke such cases (i.e. asuint(uint) -> floatBitsToUint(float(uint))). This change defines the missing overloads as returns with regular casts. #jira FORT-25869 #jira UE-34263 Change 3131153 on 2016/09/19 by Rolando.Caloca DR - Fix recompute normals when triangles have a LHS tangent basis Integrate from3028634- Also make meshes that don't have morphs be able to run through the recompute normals path #jira UE-35472 Change 3131228 on 2016/09/19 by Mark.Satterthwaite Duplicate CL #3114668: Always disable asynchronous shader compilation for the global shader map on Metal as some of them are needed very early. #jira UE-35240 Change 3131246 on 2016/09/19 by Rolando.Caloca DR - Shrink gpu skinning permutations Change 3131261 on 2016/09/19 by Mark.Satterthwaite Fix Metal validation failures due to particle rendering not binding buffers to all buffer inputs declared in the shader. ContentExamples Effects no longer aborts complaining that the particle system didn't bind a required buffer. Change 3131265 on 2016/09/19 by Mark.Satterthwaite Fix FMetalDynamicRHI::RHIReadSurfaceData for shared textures on iOS. Change 3131271 on 2016/09/19 by Mark.Satterthwaite Use private memory for the Metal stencil SRV workaround needed on El Capitan. Change 3131273 on 2016/09/19 by Mark.Satterthwaite Disable the lazy-encoder construction in Metal for AMD - there is a situation that causes the lazy construction to perform a clear that isn't wanted and so far this hasn't been tracked down and fixed. Until then, this will render correctly. Change 3131280 on 2016/09/19 by Mark.Satterthwaite For GLSL interpolation mode flags must come before storage mode flags and you can't redeclare the system variable gl_Layer to use a differing interpolation mode. Change 3131283 on 2016/09/19 by Mark.Satterthwaite Change the ShaderCache to not cache resource bindings in the draw states for shader platforms that don't care - reduces the number of draw states considered significantly without reducing effectiveness. We can support ShaderCache with Metal SM5 but not the RHI thread enabled so change when we enable it and make sure we load the binary shader cache. Change 3131402 on 2016/09/19 by Rolando.Caloca DR - Disambiguate callstack #jira UE-34415 Change 3131469 on 2016/09/19 by Rolando.Caloca DR - vk - Check if we can allocate descriptors off a pool Change 3131482 on 2016/09/19 by Rolando.Caloca DR - vk - Remove unused var Change 3131506 on 2016/09/19 by Mark.Satterthwaite With permission from Josh.A & Michael.T, deprecate Mac OpenGL support. For now this just means visibly warning users with message boxes - but in a future release OpenGL support will be removed from macOS. Change 3131536 on 2016/09/19 by Rolando.Caloca DR - vk - Compile fix Change 3131564 on 2016/09/19 by Rolando.Caloca DR - vk - Submit Hint - Disable framebuffer recycling as its causing a hang Change 3131625 on 2016/09/19 by Mark.Satterthwaite Inside MetalRHI add an optional cache for disposed texture objects so we may reuse them - controlled by CVAR rhi.Metal.TextureCacheMode which must be set prior to running as it can't be changed at runtime. Settings: 0 = off, 1 (default) = will attempt to reuse private memory texture objects within the frame they are released otherwise they are disposed of as before. Setting 2 extends the caching to all textures - though Managed/Shared textures cannot be reused until after the frame in which they were released has been processed on the GPU. In this mode id<MTLTexture> objects are never returned to the OS so in order to conserve VRAM calls to setPurgeableState are made to allow the driver to reclaim unusued memory if required. Change 3131630 on 2016/09/19 by Mark.Satterthwaite More statistics in Metal added to track down where performance was going in a particular project but which may be more generally useful. Change 3131955 on 2016/09/20 by Gil.Gribb Merging //UE4/Dev-Main@3129758 to Dev-Rendering (//UE4/Dev-Rendering) Change 3131978 on 2016/09/20 by Gil.Gribb CIS fix Change 3132584 on 2016/09/20 by Ben.Woodhouse Add some additional checks to help track down a rare crash with terrain rendering and shader recompiling #jira UE-35937 Change 3132696 on 2016/09/20 by Mark.Satterthwaite Use set*Bytes to handle uploading buffers < 4Kb when available - this is faster than lots of small Metal buffers and reduces the amount of GPU heap fragmentation. Where the API feature isn't available or hasn't been tested yet we'll use another ring-buffer inside the MetalCommandEncoder to emulate it. Change 3132772 on 2016/09/20 by Mark.Satterthwaite Rework Metal's handling of RHISetStreamSource calls that override the stride of vertex declarations to be much more efficient. Change 3132870 on 2016/09/20 by Ben.Woodhouse Fix mac compile error Change 3133049 on 2016/09/20 by Brian.Karis Changed light source shapes in reflection captures to use alpha Change 3133057 on 2016/09/20 by Brian.Karis Alphaed out on spot light cone as well. Change 3133263 on 2016/09/20 by Rolando.Caloca DR - vk - Debug names for objects Change 3133292 on 2016/09/20 by Rolando.Caloca DR - vk - Fix SRGB upload/formats Change 3133395 on 2016/09/20 by Rolando.Caloca DR - vk - SM5 fixes Change 3134026 on 2016/09/21 by Gil.Gribb Merging //UE4/Dev-Main@3133983 to Dev-Rendering (//UE4/Dev-Rendering) Change 3134663 on 2016/09/21 by Chris.Bunner Merging Dev-MaterialLayers to Dev-Rendering, CL 3134208. Initial material attribute extensibility changes. #jira UE-34347 Change 3134730 on 2016/09/21 by Arne.Schober DR - [UE-34481] - Fix minor brokenness found by Gil Change 3134792 on 2016/09/21 by Chris.Bunner Fixed compile errors for non-editor builds. Change 3135214 on 2016/09/21 by Rolando.Caloca DR - vk - Fix visualize texture - Dump memory when OOM (to track leaks) Change 3135225 on 2016/09/21 by Rolando.Caloca DR - vk - Ensure on exit if mem leak - Update fences if running wait for idle Change 3135672 on 2016/09/22 by Gil.Gribb Merging //UE4/Dev-Main@3135568 to Dev-Rendering (//UE4/Dev-Rendering) Change 3135793 on 2016/09/22 by Rolando.Caloca DR - vk - Set dynamic state after binding pipeline or on a fresh cmd buffer Change 3135816 on 2016/09/22 by Rolando.Caloca DR - Add names for d3d on renderdoc Change 3135894 on 2016/09/22 by Chris.Bunner Fixed initialization order warning. Change 3136024 on 2016/09/22 by Rolando.Caloca DR - vk - Fix stencil faces Change 3136042 on 2016/09/22 by Marcus.Wassmer Fix compile error Change 3136046 on 2016/09/22 by Chris.Bunner Renamed material for PostTonemapHDRColor visualization to reflect actual usage. Change 3136308 on 2016/09/22 by Uriel.Doyon Changed how the component relative rotation is computed, in order to have more consistency after blueprint rescript. #jira UE-36094 Change 3136798 on 2016/09/22 by Chris.Bunner Gather object references from stereo view state in USceneCaptureComponent. This matches behavior of other classes such as ULocalPlayer. Change 3137092 on 2016/09/22 by Rolando.Caloca DR - vk - Rename pipeline to gfx pipeline Change 3137263 on 2016/09/22 by Mark.Satterthwaite Duplicate CL #3135157: Fix one cause of Metal crashes loading into a zone - the PlanarReflection shader code needs to always set the IsStereoParameter so that the shader can perform the if-test without causing an invalid GPU access. #jira FORT-30061 Change 3137265 on 2016/09/22 by Mark.Satterthwaite Duplicate CL #3135169: Correct Metal texture creation for AVF media framework - we can't provide a render-targetable version of the texture without blitting. The native texture we get is a GPU copy that can be made CPU accessible (i.e. it is not tiled). Change 3137266 on 2016/09/22 by Mark.Satterthwaite Duplicate CL #3135237: Metal validation layer fix: under Metal if there are no reads from the vertex stage-in buffers we should use the Empty vertex declaration, not the filter declaration, otherwise we have to bind a redundant vertex stream buffer to silence the validation layer. Change 3137268 on 2016/09/22 by Mark.Satterthwaite Duplicate CL #3136033: To fix the Fortnite login screen force Nvidia Macs to use the set*Bytes API for small buffer updates even on El Capitan. We can't do this globally as Intel didn't implement these functions until macOS Sierra. Fix GPU selection code in MetalRHI to confirm everything is working. #jira FORT-30385 Change 3137269 on 2016/09/22 by Mark.Satterthwaite Duplicate CL #3137164: Add stats to track exactly how many command buffers are allocated and committed each frame to work out why Fortnite on AMD is hanging, which turns out to be because each texture update/reallocation ends up in its own command-buffer. This needs to be rethought to pack these into fewer command buffers with the same synchronisation requirements to minimise command-buffer splits but for now we'll just make the default sufficiently large that we shouldn't see the hang until the work is done. Also ensure that command-buffer failure is always fatal - there is no way to recover or continue if a command-buffer fails. #jira FORT-30377 Change 3137606 on 2016/09/23 by Gil.Gribb Merging //UE4/Dev-Main@3137560 to Dev-Rendering (//UE4/Dev-Rendering) Change 3137936 on 2016/09/23 by Rolando.Caloca DR - Split RHICmdList clear into color & ds in prep for changes Change 3138346 on 2016/09/23 by Rolando.Caloca DR - vk - Some renaming and splitting classes in prep for compute Change 3138628 on 2016/09/23 by Rolando.Caloca DR - vk - Fix mem leak on framebuffers Change 3138721 on 2016/09/23 by Daniel.Wright Better comment for r.DefaultFeature.AntiAliasing Change 3138722 on 2016/09/23 by Daniel.Wright Fixed assert from decals with MSAA due to binding the Scene Depth Texture instead of surface Change 3138723 on 2016/09/23 by Daniel.Wright Corrected GC doc Change 3138892 on 2016/09/23 by Daniel.Wright Fixed instanced static meshes being unbuilt after a lighting build if you ever cancelled a previous lighting build Change 3138905 on 2016/09/23 by Daniel.Wright "Optimizations" -> "Optimization Viewmodes" Change 3138939 on 2016/09/23 by Daniel.Wright Disabled the stationary light overlap viewmode with forward shading Change 3139710 on 2016/09/26 by Rolando.Caloca DR - Rename and added texture RHIClearDepthStencil -> RHIClearDepthStencilTexture Change 3139820 on 2016/09/26 by Rolando.Caloca DR - Remove prefix from shader frequency strings Change 3139828 on 2016/09/26 by Marcus.Wassmer Add SetShaderValue() specialization for bools on AsyncCompute commandlists to match the Gfx specialization.

Lighting is built separately for each lighting scenario with actors / lights in all other scenario levels hidden. Only one lighting scenario level should be visible at a time in game, and its lightmaps will be applied to the world. * Most outputs of the lighting build now go into a separate _BuiltData package. This improves level Save and AutoSave times as the separate package will only be dirtied after lighting rebuilds. * If a lighting scenario is present, all lightmaps are placed inside it's _BuiltData package. This means that only the currently loaded lighting scenario's lightmaps will be loaded (Day or Night, but not both). This also means that lightmaps for a streaming level will not be streamed with it. * For backwards compatibility, existing lightmaps are moved to a new _BuiltData package on load. * Reflection captures and precomputed visibility were not moved to the separate package. Reflection captures are force updated on load of a lighting scenario level, which can increase load times. Change 3140361 on 2016/09/26 by Daniel.Wright Lighting Scenarios UI Change 3140582 on 2016/09/26 by Mark.Satterthwaite Duplicate CL #3140166 Fix the video playback in Fortnite - bind our shader resource texture as the render-target texture as for some reason the playback code expects it there, even though we could never provide one. #jira FORT-30551 Change 3140584 on 2016/09/26 by Mark.Satterthwaite Duplicate CL #3140131: Fix crash under the validation layer & Nvidia's El Capitan (10.11) drivers when distance field particle collisions are used without any scene distance fields available - bind the black volume texture when that is the case to avoid bad access on the GPU. #jira FORT-30622 Change 3140586 on 2016/09/26 by Mark.Satterthwaite Duplicate CL #3140450: Fix launching the game on Intel GPUs by disabling Tiled Reflections on Intel for macOS Sierra like we did for El Capitan as there's currently a driver bug to means it doesn't work properly. #jira FORT-30649 Change 3140594 on 2016/09/26 by Zabir.Hoque Fix benchmark shaders register bindings.

Change 3142065 on 2016/09/27 by Benjamin.Hyder Updating Lighting Scenario map Change 3142262 on 2016/09/27 by Mark.Satterthwaite Change Apple RHI initialisation to select the first compatible shader platform to decide which RHI to initialise. Internally in MetalRHI we must gracefully fallback to a lower feature-level when this initial selection is not available on the current device/OS, in which case we need to validate that the selected shader platform was actually packaged. The order of initialisation is different per-platform: On Mac: Order of initialisation is the order listed in TargetedRHIs .ini specifications.

The Default value for the Skincache mode was changed to enabled. The reasoning behind this was that it will be auto disabled when Skincache Shaders are disabled, and runtime toggle is a debuging feature that mainly programmers are dealing with. The Recompute Tangents option in the Skinned Mesh is now automatically grayed out when no Skincache Shader Permuations are available. Change 3142537 on 2016/09/27 by Daniel.Wright Fixed r.ScreenPercentage with MSAA - a scissor rect was being setup during the resolve and not reset Change 3142691 on 2016/09/27 by Daniel.Wright Disabled renaming of legacy ULightmap2D's to the separate package since UMapBuildDataRegistry is no longer put in a separate package for legacy content Change 3142711 on 2016/09/27 by Daniel.Wright GComponentsWithLegacyLightmaps entries get handled by USceneComponent::AddReferencedObjects, fixes a crash when you open a map directly from the content browser Change 3142712 on 2016/09/27 by Daniel.Wright Separate category for ParticleCutout properties Change 3142762 on 2016/09/27 by Uriel.Doyon Added per static mesh and per skeletal mesh UV density data. The data is now saved and available in cooked builds. The density are computed by the engine but can be overridden by the user in the material tabs. Texture streaming intermediate component data is now per material instead of per lod-section. New ViewModeParam in FSceneViewFamily allowing context specific param per viewmode. This is currently used to show which UV channel and which texture index is being shown in the texture streaming accuracy viewmodes. This replaces r.Streaming.AnalysisIndex Renamed texture streaming viewmodes: MeshTexCoordSizeAccuracy -> MeshUVDensityAccuracy MaterialTexCoordScalesAccuracy -> MaterialTextureScaleAccuracy MaterialTexCoordScalesAnalysis -> OutputMaterialTextureScales Improved UV density computation and viewmode. LightmapUVDensity is now computed separately from UVChannel Density. Fixed texture streaming for instanced static mesh component and derived types. Change 3143464 on 2016/09/28 by Daniel.Wright Removed 'experimental' from forward shading setting Change 3143508 on 2016/09/28 by Chris.Bunner Added component type handling to FoldedMath and Length material expressions. #jira UE-36304 Change 3143557 on 2016/09/28 by Rolando.Caloca DR - Back out changelist 3142292 Change 3143563 on 2016/09/28 by Rolando.Caloca DR - vk - Force hlslcc re-link Change 3143648 on 2016/09/28 by Daniel.Wright Moved GetMeshMapBuildData to UStaticMeshComponent since FStaticMeshComponentLODInfo::OwningComponent can't be initialized reliably in the case of SpawnActor off of a blueprint default that has LODData entries already. Change 3143661 on 2016/09/28 by Chris.Bunner Warning fix. Change 3143723 on 2016/09/28 by Daniel.Wright DumpUnbuiltLightIteractions after lighting build for debugging Change 3143822 on 2016/09/28 by Arne.Schober DR - Refactoring of the ViewMatrices. Moved the Derived Matrices into the FViewMatrix struct. Made all members private do emphasize the static constness of that struct after creation. Renamed the heavy weight members on this struct to Compute*. Methods that modify The ViewMatrices have been renamed to Hack* to discurage their use in the future until a better solution for those problems is found. The ViewMatrix modification is especially misleading because it only changes the State of the ViewMatrices to read their Position from the Material Editior as if coming from the Lightsource (mainly for manual bilboards) as well as doing someting similar to generate CPU bilboards for shadows. Change 3143860 on 2016/09/28 by Benjamin.Hyder Updating TM-Noise map to include 3d noise examples Change 3143939 on 2016/09/28 by Rolando.Caloca DR - vk - Better debugging of submissions - Added r.Vulkan.IgnoreCPUReads to help track down hangs on some ihvs Change 3144006 on 2016/09/28 by Brian.Karis Fixed PixelError not being set correctly with LOD groups.
