Houdini 16.5 Nodes Particle nodes

Collect POP node

Merges particle streams together so you can act on them collectively.

Complex simulations may contain many particle streams. For example, in a fireworks display, the particles shooting up can be one stream. The explosions are another stream. Sparkles can make up yet another particle stream.

The Collect POP essentially allows you to merge particle streams together. It sequences the inputs together, so following nodes will act on all of the particles collected from this node’s inputs.
