POP network questions

[Juraj]

Hello,

I have few questions about POPs.

 

I have a POP (new) network where I source particles from other object. In POP network there is static object for collision. Outside the POP I want to make volume from particles, but volume is created from collision geometry as well. How do I get rid of collision geometry which is outputed from POP network? Maybe delete SOP is solution but I cannot figure expression rule that isolates particles from collision geometry.

 

Second question - I'd like to get rid of particles, that have not been hit by collision yet. I want them to appear after they hit collision geometry. I know that it must be done after POP network. I've tried assigning them into a group in POP solver and then delete not selected with delete SOP, but the result was that there stayed only particles that hit geo in that frame and when they bounced they disappeared.

 

Thanks

The solution to assigning hit particles to group may be with POP Stream. What would be VEXpression to add particles from hitTemp group (set in POP solver) to hitPerm (set in POP stream)?
