Acadia, If you are ONLY selecting Collide against Figure 1 change this. Unchec Universe, which will claer all of the check boxes. Check the following: Ground (sorry forgot that earlier) abdomen hip l&r Buttocks l&r thigh l&r shin l&r foot l&r toe Also, since you are using WW to fit the dress, besure that the hip are (the part you are clothifying) does not intersect the figure 1 anywhere. It's best to bee too big if anything. If there is an poke thru on a collision group AT ALL it nullifies the collsion detection. "I have the MFD and "Hip" selected before entering the cloth room. I click "new simulation". However, when I go to "clothify" the hip part of the dress, I get a message saying that the part is already included in the simulation and that I can't clothify it again. There is no "Collide against" button available for me to use though. So I cancel and try again. The second time I cancel I get the "collide against" button which allows me to set the collision." In this case you would need to DELETE the Simulation and start from scratch. I'll be watching the tread if you continue to have problems. THis has been a fairly straight forward process, but I may be missing some detail from habit. I "run" something thru to see if I pick any ting up. mike
