Awesome prop BB. It looks great. You weren't kidding when you said it renders slow. So, I tired it out one the scene I'm working on. The scene has 2 riverboats, a background image on a one sided square and your water shader. With one of these smoke plumes, Poser 6 and Poser 7 just about hangs. the riverboats have 2 smokestacks each so I'll have to use 4 of the plumes and by the way it's rendering with one, 4 will probably kill Poser.
