How to deactivate a spawned particle emitter once player leaves box trigger?

Hey,
Pretty new to Unreal and following some tutorials I’ve managed to create a box trigger that spawns a fire particle emitter at a certain location, but I also want the emitter to stop only when the player walks outside of the box trigger. The idea is of a hallway that lights up new fires as the player moves further, but the ones behind disappear.

The spawning on the fire looks like this:

The problem with this blueprint seems to be that I cannot find a way how to reference the newly created particles for OnActorEndOverlap

Also - I’d need the particles to reappear if the player walks back into the previous box trigger

Hello! Spawn Emitter at Location node returns pointer to created component, so use it )
