Particular: Trying to keep same amount of particles form start to end
on Jun 16, 2009 at 9:44:57 pm

I'd like to move some particles along a motion path, but I need them to start and finish with the same amount.

What I'm doing is moving a "comet" along a motion path. The particles making up the comet are custom particles of a logo element that I want to move throughout a specific scene.

That part is no problem. I'm just having problems creating - say - 50 particles - and keeping that number from start to finish. Right now the comet keeps emitting new particles. Any setting I've tried either removes or add too many particles or don't get close to what I'm trying to do.

Any advice would be much appreciated.

Thanks,

Ray

Have you keyframmed the emitter to emit on frame 1 and stop emitting on frame 2. Then make sure your particle life is set to the comp duration. Adjust the particles per second keyframe on frame 1 until you get the right amount. Then you should have the same amount of particles for the comp duration.

Best of luck

Your suggestion is exactly right. Finally figured it out awhile ago, but thanks for posting. Much appreciated.

Sorry I took so long to respond. I use Particular ALL the time. In fact, I am working on a training dvd as we speak. I usually haunt the main after effects board and did not even know this board was here. Glad you got it sorted.

Will be happy to. The dvd will be a Creative Cow Master Series dvd and will be advertised here at the cow. I will probably be putting out some free tutorials regarding particles about the same time. So, be on the lookout.
