Detailed Description

FSkeletalMeshLODRenderDataToDynamicMesh can be used to create a FDynamicMesh3 from a FSkeletalMeshLODRenderData, which is the variant of the mesh in a SkeletalMesh Asset used for rendering (and which is available at runtime). The FSkeletalMeshLODRenderData has vertices duplicated at any split UV/normal/tangent/color, ie in the overlays there will be a unique overlay element for each base mesh vertex.

TODO: The code mainly follows the logic of the StaticMeshLODResourcesToDynamicMesh.h with the addition of the skinning weights and bones. Both should be refactored to use ToDynamicMesh interface instead.

map from DynamicMesh vertex Id to FSkeletalMeshLODRenderData vertex id. NB: due to vertex splitting, multiple DynamicMesh vertex ids may map to the same FSkeletalMeshLODRenderData vertex id. ( a vertex split is a result of reconciling non-manifold MeshDescription vertex )
