- Refactor recompute-UVs-for-groups/islands out of ParameterizeMeshOp/Tool into RecomputeUVsOp/Tool. RecomputeUVsTool supports selection of active PolygroupLayer when applicable. Add support for auto-repacking.
- Clean up ParameterizeMeshOp/Tool, remove functionality related to recomputation that was moved to Recompute tool, add separate property sets for UVAtlas and XAtlas
- Add FDynamicMeshUVEditor::QuickPack() function to compute UV layout
- Add support for Polygroup Layer selection in SetCollisionGeometryTool, if only one source object is in use

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.

Add support for brush alphas to VertexSculptTool. Replace cycle counter instrumentation with insights tags. Perf optimizations for normals computation, additional async refactoring.
MeshSculptToolBase now allows subclasses to override final commit behavior, added support for variable stamp spacing and flow rate, expose various other internal functions to subclasses. Update various brush implementations for new stamp system.
Add support for custom brush stamp Alpha function to FSculptBrushStamp
Add FMeshSculptBrushOp::::SupportsVariableSpacing(), brush stamp impls use this to indicate that they support custom Alphas. Implement support in various Sculpt brushes.
Add various functions to recompute normals for a triangle region to UE::SculptUtil
FMeshVertexChangeBuilder now supports only updating vertex color.

- add support for VertexColor shader mode in EMeshEditingMaterialModes, handle in sculpt tools
- MeshSculptToolBase: add ability to hide view and brushop properties, add ability to show surface or volumetric indicator, add tracking of last-hit triangle ID
- add UPolygroupLayersProperties, standard property set for listing and picking from available Polygroup layers for a mesh
- add MeshGroupPaintTool, uses above extensions to allow for painting per-triangle integer polygroups
