Emo I think this site is a site developed to people that likes 3d and want to learn about it, people every day ask questions about different topics, and some of thoes questions are answer and some other's don't. I know a lot of maya, but I dont know how to create this effect, I search the web but I found how to create fire or cloud or smoke with fluids, don't found the kind of effect that I was looking for. and I also look in the help of maya but there are a lot of topic's and I got frustated. Anyway If you don't want to help is ok, but maybe some other person will, beside If i learn how to make the effect and make the animation I'll not recive any monney for it, I think I'll show to them that I want to work and maybe they will think in me for some other animation proyect. If some other people think I'm doing wrong with this post let me know about it.
