what your trying to do is impossible, it would require you to change the basic shape of the collision. there is however a way to accomplish what your looking to do but with another method. now im assuming you want when the camera sees the player then it does something right? if thats the case you just need to add another check in to see if the player is visible via a line trace.
ok so in the example below we first need to detect if there is a overlap of the sight volume (on begin overlap), then we need to see if it was the player character that overlapped (get player character → equal → branch), next we need to determine if there is anything in between the camera and the player (line trace from camera to player location), then if theres no hit we know there was nothing between the camera and the player (return value, branch).
this entire script basically asks two questions: is the player in range? and is there anything between me and the player?
