I'm not exactly sure as I haven't really gotten into it other than an overview. I think there are some more compositing tutorials in the works here at SM as per a conversation between me and Izzy (https://forum.simplymaya.com/showthre...&threadid=2378). As far as the incompatible programs go and if you haven't seen this before, you might want to check this tutorial out on breath vapor simulation: https://www.digitalproducer.com/2001/...mayabreath.htm. You would probably output the original movie clip as a sequence of images then load them into an image plane as an animated sequence.
