Camera Trigger Volume Question

Hi everyone,

I am a bit new to UE4 and have looked but cannot find a solution to my problem.

So basically I am Using an on actor begin overlap with a trigger volume to set an RTPC value in Wwise when you enter and leave the trigger volume. I got this to work great! But I am using a camera pawn and for a top down game and I want my camera to trigger the RTPC when a move that around and through the trigger volume rather than my character.

How would I go about doing this in BP?

Thank you
