Particles not killed on collision within a blueprint...
Currently I have a moving light with dust particles and a cone shaped mesh for them to collide with in the same blueprint. The idea is to kill off dust particles that aren't in the light cone anymore as it points in a different direction. I've added collision modules to my particle system and they collide with world geometry just fine, but are ignoring the command to be killed when they collide with the mesh within the blueprint, no matter what settings I apply.
Basically I am posting it here because its first query in google search about this issue. So basically I'm answering it to prevent others to struggle with it:
In Particle System tab, whenever you want to include particle collision within blueprint, just untick the box "Ignore Source Actor" in Particle's "Actor Collision".
