I'm trying to use Jim Burton's Dynamic Glamour Sheath on Aiko 3. I'm following the directions provided with the garment (Poser 6 vintage). JB provided a set of poses that had 16 frames so I didn't have to start from scratch. When I calculate the simulation, I can see the dress follow the changing pose, but at the end, the window flashes and the dress returns to its zero shape. Can anyone give me an idea where to start troubleshooting?
