I can take a cube, for example, and using a high res square drape it over the cube. But if I import an OBJ figure and take this the hi res primitive square, I cannot set up the collide information. When I click on add/remove and select figure and ground and click OK. Nothing happens and the box for the object to collide with still says none. Any ideas? I assume all is set up correctly because the high res primitive square will drape over the cube. Thanks. I am getting very frustrated. I normally work in DAZ, but the cloth room is easier, theoretically, than the dynamic module for DAZ which I can't seem to get to work either. I want to make sheets to cover parts of figures.

From what you describe it should be correct and working. Can you try to show some screenshots of the scene, settings, Poser version etc. Might be easier to figure out what might be wrong.
