Particle Emitter as Stroke
I read a post by Steve Roberts about how to use a stroke as a particle emitter. The instructions where to create a mask, render a stroke onto it, precompose, then put partcular on a solid and set the emitter to layer.
However, I am gettng random partcles. There must be somethng I am missing.
This is what I really want to do. I have a mask with an animated stroke. As the stroke appears from 0% to 100%, I need the emitter to effectvely go with it… getting longer and emitting particles along the “lit” portion of the stroke. That is, the emitter gets longer as the stroke elongates along the mask…
