It is sure that I can set particle life in POP wrangle or somewhere else, but that is not what I want. Maybe I want to keep the information of all the points, but just make a copy of several of them for some post processing, deleting what I don't need seems to be a natural and simple way.

When using the old particle system, a delete note can be connected to the popnet to remove some points among particles. But I found this method doesn't work with the new particle system. Is there any method to delete points from the NEW particle system?

POP Kill

I do not want to kill particle inside the pop net. For instance, I want the particles to have collision with a surface and record the hitpos, then remove those particles that went through the surface. if I kill those particles, the information of the hitpos is also gone with the points. Delete SOB node just like to make a copy of some points, while I can still use the information of those deleted points from the node above the delete node…

I found a method that using two sets of pop solvers and pop objects. For one of them, kill some particles, but for the other keep all of them…

What is the problem with using Delete SOP or Blast SOP after new POP net (DOP net) the same way as you used with the old one?

It's a shame, I make some connection mistakes in my net work, now delete node can work correctly…

Still thanks for your reply…
