I was wondering if anybody could help me a couple of problems I'm having....
first is there any tutes available on making dust and debris fly around such as when a plane crashes etc?
and second in one scene I'm working on a gantry crane is being used, the winch system can't be seen but I need to figure out how to make the cable become shorter as the load is lifted, and vice-versa
I really appreciate any help I can get
