Hmm, somehow I missed this thread. The biggest problem with the Grouping tool is it's name. It gives people the wrong Idea about what it does. It DOES NOT "Group" body parts. It's main function is to "cut apart" solid meshes and assign materials to create new figures. You import your solid mesh model, cut it into groups and materials then create a new figure with the prop spawning functions and Hierarchy Editor. Hope this clears things up. -Jeff H.
