He said something about the process in Character Creators - from what I understand he made the wolf bits as a conformable character that snaps onto the existing p4 man/woman. Which means he used existing geometry with existing morphs so it should allegedly take any existing wolfhead morph targets. Just like Lemur's human body figures can take any existing body morphs (but not animal head morphs - 'cause the mesh is different). I think I like Lemur's better :) Mostly because of the animal paws - and if you fiddle with the bending you can get a good digitigrade posture.
