I need grouping my particles, but i want do it randomize and gradually. how i can do it?

You can do it with some way ,for example Point Cloud !
I made a very simple asset to select random and gradually ,But It's work only on the Points Not Particles !
But It's not important ,You can do same way in the PoP Network Instead Geometry Solver to select Particles.

Thank you …. You really helped me))
