Animating emitters down a path.
on Dec 2, 2010 at 12:44:00 pm

I have to animate a series of pulses down a curving path. They need to be different animations each having different amounts of pulses. My first thought was to do this in After effects or similar but got to thinking that there might be a way of doing this with super emitters and the child emitters following the path (and that that might be way quicker in the long run).

Does this sound possible and does anyone have any ideas or tips as to how I would be able to do this?

(Apologies if this is obvious but I haven't used PI for a couple of years and am currently trying to speed through the tutorials. Any help would save me quite a bit of time.)

Huge Regards
Dave

Only parent emitters can have their position specified (follow a path). Child emitters (free emitters) can't.

Ah. so I can't do it then. shame. (A feature request maybe?)
Oh well. I can always animate 1 in PI and multiply it in AE.

Thanks Alan.

Or duplicate it in pI3.

1) animate the first emitter
2) copy the emitter
3) move 15 frames ahead (or however many frames you want between the two emitters) then paste
4) repeat steps 2-3 as needed.

I haven't done this in a while but I think it works.

Ahhh. That might do the trick. I'll give it a try.
Cheers Alan!

Another idea I had would be to render out the particle animation and then load that into a new emitter and then set it to emit at regular intervals (not sure how to do that bit yet). It may well be a bit memory intensive though. What do you think?

Way easier doing it the way I suggested. I just made a test project setting up the first emitter, then using copy and paste for the followers. The followers took me about 30 seconds total to do... slide the frame marker, ctrl+V, slide the frame marker, ctrl+V, etc.

Here's the file:

Thanks Alan. That does seem much easier (I do have a history of taking the scenic route :-) ) Many, many thanks for taking the time to do this!
