This is related to another post I made about particles denting geometry. I have a pretty well functioning sim however what I need is the particles to split once they hit the geometry. I have this functioning ok by using the pop replicate but I only need the first particle hit to dent the geometry. The replicated particles are also denting the geometry. Is there a way I can stop the replicated particles from doing this? Someway for them to be visible but be excluded from interacting in the sim?

Thanks guys!!

Hey guys!

Ok so I am working on a little particle sim where I attach metaballs to particles and they are denting geometry. It's working pretty well however I would like variation in the dents created. I have made a couple of different shapes from combining metaballs and I would like each particle to be born with one of the variations. I then have these variations plugged into a switch and I added the expression rand($F) which does indeed mix up the assigning of metaballs however every time the switch changes the metaball applied to the particles it changes it on EVERY particle even once they have been birthed which results in this constant flickering in the dents. Soooooo very longwinded but is there a way to keep one variation assigned with each particle once birthed? Do i need to use a different expression or a different node maybe?
Thanks so much for any help!! : )
