I have a pretty wimpy little Windows ME and I have inconsistent results with the Cloth Room. Sometimes I get a nice result. Other times the Cloth Room decides to create 600 frames...when it goes beyond the number of frames I have set, I cancel the process because I know it will be endless at that point. In my successful attempts, none have taken over night (but my graphics tend to be simple). My problem is, because I'm so stupid, is that I don't know how to tell if I have intersecting polys. I know something is going wrong in my unsuccessful attempts but it isn't clear to me how to determine what it is (in other words, I've no clue how to troubleshoot the cloth room). Sigh. The times it works makes you yearn for it to work correctly all the time because the effect is so lovely.
