Fixed materials in the BakeRC tool missing UV layer switches or controls for brightness of the Base Color, Subsurface Color or Emissive channels
Removed the unused AO Multiplier setting that appeared in the Preview panel of the tool UI
Improved performance of BakeRC tool baking step by not recomputing the target mesh spatial index and uv charts
Improved the clarity of the analytics code since the sub-classing has enabled us to more easily use custom BakeRC analytics

Add UE::ToolTarget::SupportsIncrementalMeshChanges() and ::ApplyIncrementalMeshEditChange(), these allow a Tool to directly edit a DynamicMeshComponent in the level (and emit corresponding MeshChange) so that a Tool can emit multiple undoable edits on a DynamicMesh
Add new USingleTargetWithSelectionTool base tool class, this is a USingleSelectionTool that can receive a FGeometrySelection. USingleTargetWithSelectionToolBuilder configures this type of Tool as necessary.
Add new LinearExtrusionOp dynamic mesh operator, provides linear-extrusion API to FOffsetMeshRegion using new Operator design (mesh shared via FSharedConstDynamicMesh3, CalculateResultInPlace() function to simplify direct usage in geometry script/etc)
Add new ExtrudeMeshSelectionTool, subclass of USingleTargetWithSelectionTool, exposes new LinearExtrusionOp, uses above ToolTarget functions to directly edit DynamicMeshComponent where possible
Enable new Tool in Modeling Mode
Add a few new functions to UMeshOpPreviewWithBackgroundCompute to simplify configuring InProgress and Secondary materials
Small additions to USingleSelectionTool

ModelingTools - MeshAttributePaintTool and SkinWeightsPaintTool. Use non-maniforld vertex ids when provided. fixes a crash
SplitMeshesTool - removed an unsed mesh conversion.
ModelingComponents - ModelingToolTargetUtil - request non-manifold vertex Ids on dynamic meshes when converted for tools.
DynamicMeshViaMeshDescription - request non-manifold vertex Ids on dynamic meshes when converted for tools.
ModelingObjectCreation - make sure to strip the any src vertex IDs from a dynamic mesh during object creation.
#rb Ryan.Schmidt

MeshConversions - MeshDescriptionToDynamicMesh - Add ability to capture non-manifold source veretx IDs in the form of a vertex attribute.

This change addresses the errors found with applying certain modeling tools to skeletal meshes due to the old code not using the appropriately setup MeshDescription for skeletal meshes.

Add new MeshTargetInterfaceTypes.h file, move EStaticMeshEditingLOD there and rename to EMeshLODIdentifier. Add FGetMeshParameters and FCommitMeshParameters types.
IMeshDescriptionProvider::GetMeshDescription() now takes FGetMeshParameters to optionally specify LOD.
Added IMeshDescriptionProvider::GetMeshDescriptionCopy() function, to handle copy-case.
removed IMeshDescriptionProvider::CalculateAutoGeneratedAttributes(). This was only being used to force Tangents computation, which can now be done via GetMeshDescriptionCopy() and FGetMeshParameters.bWantMeshTangents option
IMeshDescriptionCommitter commit functions now take a FCommitMeshParameters to optionally specify target LOD.
StaticMeshComponentToolTarget::GetMeshDescriptionCopy() added, optionally computes auto-generated MeshDescription attributes on the copy
StaticMesh(Component)ToolTarget updated to support FCommitMeshParameters target-LOD.
SkeletalMesh, Volume, and DynamicMesh ToolTargets updated for new APIs but do not currently support any of the new LOD parameters. These should never be called w/ LOD parameters in the current codebase, ensures added to catch any errors (they would be non-fatal).
UE::ToolTarget::GetMeshDescription() and GetMeshDescriptionCopy() in now take FGetMeshParameters argument.
Removed bWantMeshTangents param to GetMeshDescriptionCopy(), now done via FGetMeshParameters. Updated call sites.
TransferMeshesTool now supports specifying read and write LOD (numbered or HiRes) for StaticMeshComponent source/target, via above functions.
TransferMeshesTool can now also target a new LOD in a StaticMeshComponent, index is 1 larger than current maximum source LOD.

Reduce surface area of MeshDescriptionProvider/Committer, replace with UE::ToolTarget:: calls where possible.
Add new UE::ToolTarget::CommitMeshDescriptionUpdateViaDynamicMesh() function. This is being used for now to avoid potential regressions as UE::ToolTarget::CommitDynamicMeshUpdate will preferentially use DynamicMeshCommitter, and I am not certain it is functionally equivalent in all cases.
Add new UE::ToolTarget::CommitDynamicMeshNormalsUpdate(), similar to existing UV version
Add new Move-variant of UE::ToolTarget::CommitMeshDescriptionUpdate(), uses new Move-variant of IMeshDescriptionCommitter::CommitMeshDescription.
Make existing IMeshDescriptionCommitter::CommitMeshDescription callback interface protected, to prevent usage of this function at public API level (will be removed in future).
Tool updates should not change, just using cleaner APIs.
EditNormalsTool now uses CommitDynamicMeshNormalsUpdate(), which does go via DynamicMeshCommitter preferentially, where it previously went via MeshDescriptionCommitter. In light testing the results appear equivalent.
AttributeEditorTool now operates on MeshDescription copies in various update functions. These are not performance-critical.
