- 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.

[CL 16650666 by Ryan Schmidt in ue5-main branch]
- Changed triangulation of volume polygons to Delaunay to avoid degenerate tris when possible.
- Added ability to set degenerate tri normals to neighbor normal to avoid creating nonplanar volume polygons if degenerate tris do appear.
- Created a path to use FPolys instead of bsp nodes to convert from volumes, as nodes get broken up arbitrarily.
- Gave volume conversion the ability to preserve group boundary edges.
- Changed PlanarFlipsOptimization to correctly deal with degenerate tris, and to respect group boundaries.
- Added legacy cleanup code that Ryan ported to make volume faces convex.
- Changed our version of the convexity code to avoid arbitrary precision cutoff, and to remove one of the places we were arbitrarily throwing away colinear verts.
- Changed on-the-fly conversion options to not try to fill cracks, as this seems to worsen any problems further.
