Okay, here's what I do, very simply: I create a flat, self-illum color in materials editor. In 3d Editor I create a cube, center it, then assign my flat color to it. I then adjust its attributes so that it doesn't cast or receive shadows, and I turn on the magic routine. I usually start with about 200 particles, set the particle size to maximum (both smallest & largest), set particle life to 60 (the length of the scene in Keyframer). In Keyframer I move the box from left to right over 60 frames. When rendered, I get a blob of glitter that pans from left to right, leaving no trail. Any suggestions?
