Subject:  finish encoding number of mesh faces in pbs shape on new meshs
 upload, and *HACK* flag it setting hollow shape to triangle. (some limited
 encoding as added some months ago, but only for viewers LOD). Use this hack
 flag to fix sop number of faces.  old meshs will still report 8 faces,
 information to fix this seems lost unless the mesh asset is decoded
