I didn't know there was a limited version and full version of VWD: what are the difference between the two? Or are you talking about the demo and the full version?

For me basically:

• Animation simulation in VWD use the number of frame from Poser
• Static simulation in VWD have an unlimited number of frame

Relation between the number of frames and simulation also depend of the range of the movement. We need sometimes plenty of frames to let the clothe follow "quietly" and sometimes one frame is enough
