Benchmark configuration:
- Test scene with 4 meshes: a mossy stone nanite mesh, a beach ball, a ball with an emissive blue cross and a hut mesh
- Target mesh: 11.8k triangles mesh, created by voxel wrapping the meshes in the test scene elements
- 4096x4096 output texture with 16x multisampling baking BaseColor, Emissive, PackedMRS and Normal maps
- 4096x4096 photo capture resolution
Unreal Insights reports the following times for the Bake call:
- Before this change: 2 mins 45 seconds
- After this change: 55.9 seconds
Aside: (Unaffected by this change) In both cases the photo capture, which is done on the game thread, took about 1 min

- add support for a Settings Preset, as an explicit Asset type. UStaticMeshLODGenerationSettings contains a copy of the GenerateProcess Settings, UStaticMeshLODGenerationSettingsFactory allows this UObject to be used as an Asset in the Editor. UGenerateStaticMeshLODAssetTool now has a Preset slot, and action buttons to Read/Write to the currently-selected Settings Asset. New Settings Asset can be created via the Asset Picker popup in the Tool, currently creating via the New Asset menu is disabled via UStaticMeshLODGenerationSettingsFactory::GetMenuCategories()
- UGenerateStaticMeshLODProcess now automatically ignores input textures that have a constant value
- UGenerateStaticMeshLODProcess now skips writing output NormalMap and MultiTexture if they are not referenced by any output Materials
- UGenerateStaticMeshLODProcess now supports configuring whether a Texture or Material will be considered for Baking. If disabled, then the source Texture/Material is used (currently the Textures are still baked, they are just ignored while configuring/writing the outputs).
- UGenerateStaticMeshLODAssetTool now exposes lists of source Texture and Materials with option to skip baking (used to configure the above options)
- wrote header comments for UGenerateStaticMeshLODProcess
- overall cleanup in UGenerateStaticMeshLODAssetTool, ie category names, organization, etc
- add TImageBuilder::IsConstantValue(), checks if all pixels of image are the same value

- extend FImageAdapter to support reading
ModelingComponents::
- Add AssetUtils::ForceVirtualTexturePrefetch(), ::SaveDebugImage() variants to Texture2DUtil
- Add support for debug image writing to WorldRenderCapture and SceneCapturePhotoSet
- FWorldRenderCapture now computes more accurate bounds (visible Components instead of Actors), and does an explicit VirtualTexture prefetch before doing render capture
- FStaticMeshAssetOptions now exposes Nanite settings to allow UStaticMeshes to be created with Nanite already enabled (currently NaniteSettings.PositionPrecision defaults to max)
ApproximateActors:
- IGeometryProcessing_ApproximateActors::FOptions now has settings for enabling Nanite on generated meshes
- ApproximateActorsImpl applies these settings, also enables VT on generated textures if necessary
- FMeshApproximationSettings/FMeshApproximationTool updated w/ new Nanite settings
