Hi Mike, thanks for the reply. I’m home now, so I found out I’m using CC Particle Systems II. I’m trying to turn the smoke on/off during a horizontal or vertical pass through the letters. I’ve tried simple masks, and animating the birth rate and max opacity attributes but it doesn’t really change anything. I hope I don’t have to make each and every letter segment a different solid/effect, that would be about a hundred!

For each horz or vert “pass” of the producer across the screen I need to turn the smoke on and off up to 8 times.

Any ideas welcome!
