Completely by accident, I just found a very nice resource at the DAZ store. It's called Ron's Flames
It's a collection of flame brushes for Photoshop. As such it can be used as a great post-work resource for TG as well. I'm not sure if you are familiar with it - I wasn't.
I needed something like this awhile back but creating flames in TG only is a heck of a job and results are rather poor. Now I discovered this. Here are a few examples of how it looks as a raw resource and in a render. Well... both examples are rather crude actually, but just to give it a shot.
