Im new to all of this, & I have had NO formal COMPUTER EDUCATION / TRAINING what so ever (ON ANY PROGRAM). What I have learned on the computer over the past 5 years is what I could figure out on my own, PLEASE BE PATIENT WITH ME.
I find it easier to make fire & flames utilizing the DENTS plug-in set in the following way-
SCALE-122, AMMOUNT 21, QUANITY-21, DETAIL-10, ROUGHNESS-50, & TURBULANCE-10.
I use this on lines (or shapes or?ect.), keeping the base or center of the flame (bottom line) white, then yellow, then red, on a black background, the gradient tool and clouds plug-in is nice for this application as shown in the tut, but I think the dents plug-in works best.
