It works sometimes when i enter the collision box, and I cant really figure out why. If it doesnt work, its only play a little part of the first audio.
If it works, It will first spawn Audio and then audio + explosion.
Yep, my bad. I totally forgot everything about the bounds in Niagara system.
For anyone else who might forget: if particles dissapper, go to the actor details under rendering and increase the Boundy.
