Can anyone inform me of the best way to do fairly realistic smoke and flames in post. I've been trying in PS, but my skills are somewhat lacking. Or if possible to do in Terragen without the post work. Any help would be greatly appreciated.
I have seen brushes for Photoshop and Gimp for doing this, but even then it takes some playing around. Try using some photos of fire and cutting and using transparency, if the brushes don't do it all.
