erasing traces
I have a pulsating TP emitter, activated via xpresso to emit a shot every 25 frames. I want these particles to leave traces behind. Think of Stromboli.
I get the Tracer to make these traces and all works fine… for the first shot.
My problem is, when the particles die, the traces are left behind, and therefore accumulate on the screen in a horrible mess after a few shots.Is there a way to erase the traces left behind by the dead particles? or at least to wipe them out every N sec/frames/whatever?

In the Tracer set Limit to From End and the Amount to something less than your particles life (in your case maybe start with 25 and go from there)

yup, I’ve got that, but it doesn’t seem to work with TP. I tried with standard emitters and it works fine, but with TP, the traces don’t disappear…

Brian,
thank you very much for this. Now just toss the tracer in your sweep and reduce the particle life to 50. You will see what I mean. When the particles die, they leave behind the loft traces, and there’s no way to get rid of them.

PS: how do you attach a c4d file in here?

I see, the trace stays, getting shorter, until it catches up with the particle termination point. hmm….

and you can’t swap groups or kill the particle, it just leaves the trail behind and it doesn’t disappear.
I’ve seen a couple of tutorials for fireworks, basically you emit particles then each particle is used to generate it’s own trail of particles that seems like it might work. I’ll look. You might want to google.
The way to upload are the icons above the message pane as you post here. The one that looks like a micro-floppy (far right icon) is for file upload. Hover over them for tool tips. -
…also a problem since the emitted ‘sparks’ remain for their lifespan once the original particle disappears maybe movement to the new particles or age effects would make that be ok
