Just want to show you guys. http://vimeo.com/33612394 http://vimeo.com/33612293 And v01: http://vimeo.com/33611981 - Different shape from the above. Simulation time is around 20 hours in a i7 8 Core 12G of ram to 240 frames of 300x3 bounding volumes. So you can imagine that is very hard to art direct. (I'm trying to solve this problem now.) I've done a custom solver to only compute what is needed. It was taking more time to render in a regular smoke solver. Any critiques and questions
