Look:
http://www.youtube.com/watch?v=RZqfnwFIMzkI want to make a cloth that has this effect while Player's running. So if I walk slowly the cloth will fly low, if I run it will fly higher. Sorry my bad english speaking.
It's possibile to do it with 3dsMax. But how then, if possibile, do I make it works on IV-EFLC ?
