[Sidefx-houdini-list] POP Collision question

That sounds interesting!  What condition are you looking for?  In Houdini's world, if the particle was supposed to collide will it allow you to tag a particle that didn't actually collide?  That would be amazing, a net for rebels.

I have a SOP that cleans up this kind of thing. It basically deletes
particles that don't meet a certain conditionby ID across their entire
life span. It's like they never existed...
