I'm trying to use a popsolver to affect certain particles in my flip fluid.

However, I'm finding the popsolver only affects particles from my flip object and won't affect particles from my source volume??

How can I say, control gravity independently for the tank particles and the particles being emitted into the tank?

It seems that the sourced particles aren't even considered in the popnet?

P.S.
I grabbed the popnet from the flip color mix example since they setup the solver in a “weird” way to source the particles.

Thanks!

What version are you using? There was a bug fixed recently that makes particles from SourceVolume DOPs work with POPSolvers:


Monday, April 30, 2012
Houdini 12.0.612: When sourcing particles, the SourceVolume DOP will now add any new particles to an already existing particle system, which allows such particles to work correctly with POPSolvers.

ahhhh!!! I knew it had to be some bug

I'm on 12.0.556 so that could be just it!

thanks for pointing that out!
