Hi, Community. A simple scene, I want particles spawn when particles hit a geo. But turns out I got an effect that when particles hit a geo, particles emit every frame. I want it only emit once. how?

have a look at pop replictate dop and use the reference stream input (2nd), set Kill Original Particle.
When particles hit something the popsolver set some hit attributes: i@hitnum, i@hittotal i@hitprim . . .
