Best thing to do for smoke from an explosion, is watch a few Loony Tunes on TV. It is a simple effect, mostly parts of a circle (arc, arc), either expanding, or moving away from the center with pieces of the explodee. A building would create a lingering smoke that dissipates, where an exploding bomb would create concentric rings of smoke that grow large and exit off screen, and a gerble would create little or no smoke. Try running a Loony Tune explosion in slo-mo on the vcr to get an idea of movement. Use a large round brush for the smoke/clouds and optics to shrink/expand them….and wha la! a boomer! 🙂

What I did recently for smoke (exhaust) was based on a theory provided by Gary Yost. First, make 2 rough conical shapes that kinda look like the exhaust funnel. Then, morph them together with a swirly FLIC opacity map. I used GRASP to create 2 or 3 random maps of various middle grey shades. This is done like this… video l mark 2000 color random(18,26) ; selects a random grey from default palette) point 0,0,319,199 loop pgetbuf 1 psave map1.pic,1 exit Do this a couple or 3 time, then save them as GIFs with Pictor. Then, you can load them into animator and make a 2 or 3 or even 4 frame flic. It will look like tv snow. Then, load it as an opacity map. I wish I had it completed so I could prove it works, but understanding the theory should convince you that it will work…
