- Move ToolTarget implementations, DynamicMeshToVolume to ModelingComponentsEditorOnly module
- move VolumeToDynamicMesh, DynamicMeshProvider/Commiter interfaces to ModelingComponents module
- Add UCreateMeshObjectTypeProperties property set to expose mesh/volume options
- Add FCreateMeshObjectParams::TypeHintClass to allow AVolume type (or other UClass hints) to be passed to creation APIs
- Add UE::ToolTarget::ConfigureCreateMeshObjectParams() util function in ModelingToolTargetUtil, tries to determine output type in a FCreateMeshObjectParams based on input ToolTarget
- Add UEditorModelingObjectsCreationAPI::CreateVolume() implementation
- Add UEditorModelingObjectsCreationAPI::FilterMaterials() that strips out any internal materials and replaces with WorldGridMaterial. This occurs when (eg) subtracting a Volume from a StaticMesh, because the temporary volume mesh gets assigned internal materials, but the Tools don't know this. Use in EditorModelingObjectsCreationAPI when creating new objects. UStaticMeshComponentToolTarget also does this filtering in ::CommitMaterialSetUpdate().
- Add ::ComponentTypeSupportsCollision() function to ComponentCollisionUtil, use to avoid checks/ensures for Volume targets
- Add support for automatic mesh simplification in DynamicMeshToVolume. Add CVar to VolumeDynamicMeshToolTarget.h to control max triangle count (default 500). Apply auto-simplify when creating or updating an AVolume. This prevents the Editor from blocking for long periods on meshes that are too high-res for volumes (even 500 is quite high).
- DynamicMeshToVolume now emits polygroup-faces that contain holes (ie multiple boundary loops) as a set of triangles, rather than emitting separate overlapping faces for each boundary loop

- add new UModelingObjectsCreationAPI and associated data structures, provides abstract API for creating mesh and texture objects from Tools that is not specifically tied to StaticMesh Actors/Assets
- new helper functions in UE::Modeling:: namespace to simplify usage of an implementation of this API registered in a ContextObjectStore
- add new UEditorModelingObjectsCreationAPI implementation of above, supports hooks for higher level to provide custom paths
- add ModelingModeAssetUtils.h, provides several functions in UE::Modeling:: namespace to be used to implement those hooks (various existing path-determination code is moved here)
- ModelingToolsEditorMode now registers an instance of UEditorModelingObjectsCreationAPI in ContextObjectStore and connects up callbacks to these path functions
- AssetGenerationUtil functions and ModelingModeAssetAPI deleted
- All Tools that previously used IToolsContextAssetAPI updated to use this new system

- 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

- add ModelingToolTargetUtil, contains helper static functions for interacting with ToolTargets without having to manually cast things/etc
- add StoredMeshSelectionUtil, contains helper functions for interacting with stored selections
- USingleSelectionMeshEditingTool now can automatically grab an available stored selection, if it exists
- Add GroupTopologyStorableSelection::GetGroupIDs()

- FTexture2DBuilder has new EmissiveHDR texture type, uses PF_FloatRGBA/FFloat16Color texture format/buffers in this case. Moved most functions from header to cpp.
- new WorldRenderCapture::CaptureEmissiveFromPosition() implementation captures PreTonemapHDRColor buffer, with showflags config such that only Emissive (and possibly some GI - untested) will be included.
- ApproximateActorsImpl now stores Emissive bake in HDR texture. Update preview material to use Linear Texture Sampler for Emissive, required to use HDR texture

- FMeshSceneAdapter updates
- if bThickenThinMeshes is enabled, then all instance meshes are converted to DynamicMesh and decomposed to find non-closed regions. Those regions are uniqued into separate meshes. The remaining closed geometry is separated out and kept as instanced.
- various utility functions added to support above
- previous code to explicitly 'thicken' open meshes into solids is removed. Instead unsigned distance is used to determine inside/outside and generate a 1/0 winding number
- instances are now sorted into an octree to speed up winding number evaluations
- If all meshes are closed (or effectively closed via above, ie will return integer winding number) then winding number query can early-out as soon as it finds a non-zero value
- Add hard-normals options in IGeometryProcessing_ApproximateActors (not exposed in MergeActors tool options yet)
- Added hard-normal callucation to ApproximateActorsImpl, and additional profiling
- Allow specification of actual ECollisionTraceFlag options in CreateStaticMeshUtil, instead of just a boolean
- Add FSparseDynamicOctree3::ContainmentQueryCancellable() variant that can early-exit

IntervalGizmo is now just registered and unregistered as needed by the MeshSpaceDeformerTool, as this is the only place it is currently used.
Previous implementation in InteractiveGizmoManager is left intact as there are a few uses outside of MeshModelingTools that need to be cleaned up before it can be deleted.
UTransformGizmo now requires it's Builder to tell it which sub-gizmo identifier strings to pass to the GizmoManager to create axis/plane/rotation sub-gizmos (and the code that registers the Builder must then provide these strings). This cleans up previous explicit references to UInteractiveGizmoManager static strings from UTransformGizmo.

- Add FImageAdapter, wraps TImageBuilder of different types and provides a consistent interface, so that other code doesn't need specializations for each image type
- FMeshSceneAdapter now supports the ability to detect and thicken "thin" meshes, by flattening the instances into unique mesh copies (generally necessary due to scaling). Can also now return statistics about the mesh scene, return a full flattened mesh (for debugging), and automatically generate a "closing mesh" that can help to cap off the base of mesh assemblies when trying to generate a solid/etc.
ModelingComponents:
- FWorldRenderCapture now writes via FImageAdapter instead of an Image4f
- FSceneCapturePhotoSet now stores less data for photo sets. BaseColor/Emissive/WorldNormal are 3f, Roughness/Specular/Metallic are 1f
- IApproximateActors and implementation now support optional base-capping, occluded mesh removal, geometric-tolerance simplification, thin mesh auth-thickening. Now creates MICs based on an input Material, instead of new Material. Added ability to emit a flattened debug mesh, and print debug info.
MergeActors:
- Expose above improvements to IApproximateActors

Add CreateDerivedMaterialInstance(), makes a new MIC for input material (either by duplicating or using MIC asset factory)
