You've done a very good job so far. I have taken a stab at this before but not with any serious detail, as all I ever wanted was tiny flames in props that were not the main subject.

You made me dig out Poser for the first time in many months. Unfortunately the complexity grows fast and now the hand-built shader I have is too much spaghetti. This is a classic shader problem that really wants to just use math formulas.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
