small example...from a still in the animation. Animated, this looks SOOOO kewl! I have some slight issues with the way the particles "live"...which I'm trying to work around. Not sure if its a bug or if I have a setting incorrect, but there is a setting for the life span of the particles. In the animation, they ALL die at the end of the life span in the animation instead of based upon each particles life span...ie, it looks like the rocket fires, the stops, then fires again, then stops..etc, instead of the particles dying one at a time based upon their individual life span. anyhow, still very cool. :) BT
