Thanks for that file, very interesting to see your setup...I'm still learning all the volume manipulation stuff, so this is great.

Thanks

It is emanating from a tube, and even if the tube geometry is not visible, the tube gets filled with smoke as it emanates the billowy smoke I'm looking for.  I would like to see the smoke emanating from "a void" as it were.
