particles emtting from a disc
on Aug 2, 2006 at 8:43:32 pm

I need to have particles emitting from a disc, but only the edges of the disc (think water dripping off a hula-hoop) So, no particles would emitt from the center, just the edges.

Can particular do this?

I think the easiest way is to use the Disc emitter and then paint Opacity over Life so it is zero for a while in the beginning.

hmmm, but I want to use a negative Z-wind paramater, so the particles are traveling away from the camera, but only emitting from the edge of the disc.

(the ability to emit particles from a mask shape would be a GREAT addition to this GREAT particle system, hint, hint)

I see, in that case I think the only option is to use a Layer Emitter - make an outlined circle in a precomp and use that as Layer Emitter. You'll need to crank up Particles/sec.
