- 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.

MeshSelectionTool: enable new decomposition support to improve painting performance on large meshes. Fix code that was doing repeated linear searches to remove elements from a potentially-very-large array. Make brush-ROI tri centroid point rendering optional.

to support that: adds some support for packing multiple meshes into one dynamic mesh via a triangle attribute, a meshreplacementchange, and some improvements to the plane cut algo

- MeshDescriptionToDynamicMesh now always enables MaterialID attribute
- add FComponentMaterialSet and FComponentTarget::GetMaterialSet() that returns for current object (eg set of Material Slot materials on StaticMesh)
- move FMeshRenderBufferSet to BaseMeshSceneProxy.h, add new FBaseDynamicMeshSceneProxy, centralizes management/initialization of RenderBuffers, default GetDynamicMeshElements implementation draws buffer set returned by subclasses
- FSimpleDynamicMeshSceneProxy and FOctreeDynamicMeshSceneProxy now subclass FBaseDynamicMeshSceneProxy, implement necessary functions/etc
- UBaseDynamicMeshComponent now manages its own set of Materials. New OverrideMaterial can be set to replace existing materials with override material during render calls (does not affect material set)
- FSimpleDynamicMeshSceneProxy now builds per-material RenderBuffers, new FastUpdateVertices function to update positions/normals/colors. Removed shared-vertex construction, now only builds split-triangle buffers.
- UPreviewMesh gets wrapper functions to manage materials, override material, tangents of contained Component
