- 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.

- 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

ModelingTools: Replace local code in UVProjectionOp with calls to FDynamicMeshUVEditor. Major rewrite of UVProjectionTool to support ExpMap projection, improve property handling, support world-space dimensions, support re-using previous projection to simplify world-space tiling, support input selections coming from PolyEdit/TriEdit, support ctrl+click and ctrl+shift+click interactions to reposition projection primitive.

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.

- Removed UExistingMeshMaterialProperties::SetMaterialIfChanged, the logic was too convoluted now that we don't actually set new materials on the PreviewMesh. Now just forcing a material update whenever any material setting changes.
- UMeshOpPreviewWithBackgroundCompute now takes material set, added ::ConfigureMaterials() that takes array (previous API remains)
- UMeshOpPreviewWithBackgroundCompute now has additional OverrideMaterial, if set then this is forwarded to UPreviewMesh as override material
