Hey Phil, I've been using Polytrans to go back and forth between Poser 4 and TS 4. What I've found is this: TS can be used with little problem it make morph targets for every part of the body except the head. I think it's because the head is really a compound piece consisting of head, inner mouth, tounge, and teeth. What I think is happening when the head is converted to COB format, is that the common vertexes where these different parts join are being doubled. This results in additional vertexes and an unusable morph target.

I'd rather stay in my lane than lay in my stain!
