I need to create flame on a person that is running. the effect needs to be very realistic, and it looks like using a fluid fire is the way to go. I am worried about being able to figure out how to get the flame to react to the movement of the person. I was looking at a couple of the gnomon Ws tutorials (pyro, and advance fluid), and was wondering if anyone had any experience with them. Also, if you have any pointers on the matter, please let me know. Thanks!
