- 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

- new correspondence-finding strategy in FMeshImageBakingCache. Added a global Thickness parameter, and now preferentially uses the ray-hit found by casting inwards from Point+Thickness*Normal. This handles the cases where a greeble/etc is just layered on top of base mesh. These kind of mesh elements are only intended to show up in the normal map, so they aren't stitched in.
- expose Thickness and World-Space options in BakeMeshAttributeMapsTool
- initialize image in Normal and ResampleImage Bakers, otherwise initial value is garbage
- add TSampledScalarField2::BilinearSampleGradientClamped and fix typo in BilinearSampleClamped() that resulted in incorrect interpolation
- add Texture2DUtil, contains functions for reading a TImageBuilder from a UTexture2D. Can read from source data if available.
- ColorConstants now returns white for group 0
- add double version of FMeshDescriptionToDynamicMesh::CopyTangents()
- add support for computing on subset of vertiecs in FMeshConvexHull
- fix up template export in TMeshTangents
- make mesh const in TImplicitMorphology, TImplicitSolidify
- accessor/etc additions in TDenseGrid2, TImageBuilder, TSampledScalarField2, TIndexedWeightMap
- add source UStaticMesh reference in FPhysicsDataCollection, function to initialize from a UStaticMesh
- update Tools affected by above changes
- add TSampleSetStatisticBuilder::ComputeMultiPass() helper function to compute stats for iterable collections in one line
- remove dead code in UVLayoutOp.cpp
