Collision and Sphere/Line Trace

I have an object that I want the player to be able to freely walk through, but needs to be detected when shot with a line trace. How can I set up the collision so that this is possible? Every way I’ve tried makes it so they both go through, or both can’t go through. I can’t seem to split it up.

set the collision to Ignore for the Collision Channel of the Player Pawn and set it to Block for the Channel of the Trace.
