- Move UCreateMeshObjectTypeProperties to ModelingComponents and update all include sites
- Added Editor Modeling Mode settings to Enable/Disable showing DynamicMeshActor creation options, and select default mesh object type. Removed CVarEnableDynamicMeshActors.
- Added optional 'Auto' output mesh type to UCreateMeshObjectTypeProperties. This can be used in Tools that have input objects and want to allow optional conversion, but default to 'just use input mesh object type'.
- Added ConvertMeshesTool, this does in-place conversion between Mesh Object types for a set of selected objects (Duplicate tool can also do this, but only for a single object, and functionality is expected to further diverge)
- Added SplitMeshesTool, decomposes a mesh into parts and creates a new output object for each part
- CombineMeshesTool now supports variable output object type. Cleaned up internals.

[CL 16768010 by Ryan Schmidt in ue5-main branch]
- ADynamicMeshActor type has a UDynamicMeshComponent subobject (similar to StaticMeshActor)
- Add IPersistentDynamicMeshSource, a ToolTarget Interface for accessing a UDynamicMesh
- Add UDynamicMeshComponentToolTarget, a UToolTarget implementing the above as well as various standard interfaces, to allow Tools to operate on an external DynamicMeshComponent
- Update UE::ToolTarget:: helper functions that get/commit via DynamicMesh to handle IPersistentDynamicMeshSource directly, instead of going via existing MeshDescription/DynamicMesh interfaces. Add UE::ToolTarget::SetSourceObjectVisible() helper function.
- Add support for creating DynamicMeshActors in UCreateMeshObjectTypeProperties and UEditorModelingObjectsCreationAPI
- register UDynamicMeshComponentToolTargetFactory in ModelingToolsEditorMode
- Rename existing internal ADynamicMeshActor to AOldDynamicMeshActor. Does not appear to be in use and will be removed in a future CL.

UMeshElementsVisualizer::SetMeshAccessFunction() now takes a TFunction with a TFunctionRef argument, instead of with a FDynamicMesh3* argument. This allows the UMeshElementsVisualizer to access the target mesh via the ProcessMesh()-style call on a UPreviewMesh, UDynamicMesh, etc, rather than receiving direct pointer access. See UWeldMeshEdgesTool::Setup() for example usage.
Add UMeshOpPreviewWithBackgroundCompute::ProcessCurrentMesh(), which forwards to the embedded UPreviewMesh::ProcessMesh() (which can be used with the above)
Add UE::ToolTarget::GetMeshDescriptionCopy() to ModelingToolTargetUtil, similar to existing DynamicMesh variant that will auto-compute tangents if necessary.

- Add UE::ToolTarget::CommitMaterialSetUpdate() and ::CommitDynamicMeshUpdate(). ::GetDynamicMeshCopy() can now return tangents if requested.
- Add IMeshDescriptionProvider::CalculateAutoGeneratedAttributes(). Default implementation does nothing, UStaticMeshComponentToolTarget implementation initializes auto-generated MeshDescription attributes. Used in ::GetDynamicMeshCopy() to get tangents (but requires a MeshDescription copy).
- Clean up handling of Tangents in Simple/OctreeDynamicMeshComponent. Add local MakeTangentsFunc() to generate the Tangents lambda, handle different cases and no-tangents fallbacks consistently.
- UDynamicMesh: add optional info arguments to EditMesh() and ChangeInfo struct. Add support for deferring change events from Edit funcs.
- Remove UBaseDynamicMeshComponent::InitializeMesh(), ::Bake() APIs, and add ::SetMesh(). Implement in Simple/Octree implementations, update all Tools that used those APIs.
- Add USimpleDynamicMeshComponent::ProcessMesh(), EditMesh(). These are now the preferred ways to read/write mesh.
- Update USimpleDynamicMeshComponent tangents handling. Externally-computed tangents are now taken directly from the FDynamicMesh3 attribute set. Autogenerated tangents are still computed and stored in an internal FMeshTangentsf, but this is no longer exposed for external updates.
- Remove UPreviewMesh pass-through functions for Tangents access, InitializeMesh() and Bake(). Add ProcessMesh()
- Update all affected Tools. In most cases these Tools have also been converted to use ModelingToolTargetUtil functions, instead of direct ToolTarget interface casting.

- 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

[CL 16561742 by Ryan Schmidt in ue5-main branch]
- 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

- 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
