Description
Associate the mesh-local blend shape target index with the absolute blend shape channel index as found in the Definition layer.
Both the mesh storage itself and it's blend shape target storage will be implicitly resized (if needed) to provide storage for the number of meshes and/or blend shape targets that are inferred from the specified indexes.
