How to check with what the particle collided [UE4]

Hi. Is it possible to check with what Actor the particle collided with and get that information over to Unreal Engine 4 and into Blueprints? If yes, would someone be kind enough to tell me?

Thank you for your time.

Hi. First of all, sorry for the late answer.

It is currently impossible to get the actor collided by a particle, or check in the actor if it collided with a particule from a spawner. Mostly because it would cause performances issues.
However, depending on what you want to do, you can try to use the Particle Events feature in the PopcornFX Editor(edit-cf: 'OnCollide' Event), coupled with the Event Listener in blueprints. Basiclly, it will allow you to broadcast an event from your effect, triggering a custom delegate in blueprints. Inside your delegate's scope, you will be able to recover any particle field that was previously registered.

Let me know if it helped you.
