Thanks guys!

I just finished a render with the "sitting" morph, here it is.   I set it to collide against both GJ and the wall she is sitting on.  Notice how Poser seems to do a different material on the "inside" of the cheongsam, almost like it has a lining.

Anyway, as you can see, it drapes a lot better than the one above, the morph is a big help.  Using the morph, she is already sitting in Frame one, instead of being zeroed, so Poser has a lot less work to do.
