So i followed a tutorial to make a tablecloth in blender http://www.screencast.com/t/Tt7UrXhMpbJ and i followed all of the directions carefully. But when it came time to apply the modifier, there was not only a cloth modifier, but also a "subsurf" modifier. Whenever i delete it, the tablecloth goes back to being flat instead of draped over the collision object below it. Any ideas?
