Having a collision object. How to kill particles from a defined source? I have two independent objects (P1, P2) with particle system on each of them. I have another object (C1) with collision and option kill particles enabled. Is there a way to configure C1 so that it only kills particles originating from P1, while sparing particles originating from P2?
You can let particles Die on Hit by enabling this feature for one of your P object.
Collision object with Kill Particles option can do the same, but there is not a possibility to restrict it for a specific particle system - it works globally.
Particle System Properties &gt; Physics &gt; Deflection &gt; Die on Hit


Or you can let collide particles with specific group of objects via Collision Collection.
