Carrara only recognizes one root per skeleton. This means that you can only really attach one skeleton per object/group. You can however build the facial structure off the main group to the head and use it to animate the face. For most of what I do I usually make the gross movements of the head and face off the skeleton and associate all the vertices in the head to the bone. Before doing this, though, I usually build in morphs for the face in the vertex modeller (C4Pro only). That way I can animate expressions on a separate level. As to parenting an object to the hand (gun or sword), one method is to use 2 objects: One parented to the hand in the hierarchy, and one free moving. By turning on/off "visible" in the properites, I can make it look like I'm picking up said object. It's a bit of a trick to get it right, but it does work. Hope this helps! Ken
