I like that you can add points from POP into a curve and hit it with a polywire. Very cool.
Is there a way to somehow automatically create a bunch of particles, have them stop or die and emit a new stream of particles each and have them grouped based on the original parent so that you can just polywire each separate tendril and not the whole pop system? I want to have a bunch of these tendrils all sprouting from particles.

HI
in my experience with houdini I can say that everything is possible inside houdini
, that real question is how?
I can think of a few think that I'll try to solve your situation,
you can emit a particle from an other capturing the die event on the particle,
use that particle to emit a tail and group that, and you now got a streak, once you have that you can just duplicate it around the point the parent particle died, and you can have as much streaks as you want.
check the fireworks example for reference also

hope that helps

Hey Mike,
Something like the attached? Basically just make sure you use Impulse Birth rate, and birth exactly the number of source particles each Impulse. Then you can use an Add SOP and skip the number of source points, voila!
I also only Impulse birth every 10 frames (based on the modulus of $FF) and convert to a Nurbs curve to get a more attractive smooth curve.
Only issue is the death of the particles causes a pop. I'm sure I can figure something out for that but ran out of time.
Cheers,
Peter B
