Not really in-game technique but if you have enough knowledge about flame forge. Ive looked everywhere and could not find nice compacted flame forge like a pro tutorials. At this moment I can count only 2 people who can forge flame as crazy as u can imagine I got one from artist/forger and it was really nice expierence and did not overpaid but I would love to make myself in the future.
Im talking like combine 4 flames to do 1 full flame, how to use FPT for the project (I know basic's, its just a texture), How to manipulate correctly positions of those 4 flames that combined make lets say an Bird in the backgroud.
That is what I would love to see - advanced level of flame forge. Not basic "This is button, you press to change this"
