well i have no clue :) however posette doesn't have a normal knee joist. she has a thigh and a shin and the line between them runs right thru the knee. :( .. Even with just a knee joint if it was just 1 set of polygons wide i could at least parent a smart pro to it so the prop could be stationary and not bend up. Unformtunately i know less about rigging than you do. I normally use the cr2 for posette or her clothes to do make my cr2's.
