I have an actor, and when a collision mesh hits them they vanish. I would like a particle system (spawn emitter at location) to play once and then disappear. (Auto destroy does not work in BP nor does kill on completed (in the particle system) how does this look on blueprint?
You should set this up in the particle itself. Make it loop just once (instead of the default which is infinite). I believe it’s in Required section:
Required->Duration and the set Emitter loops to 1 instead of 0.
