How can i cast to the ThirdpersonCharacter's MESH?

I want it so it detects a collision with the Thirdpersoncharacter’s (MESH) not the capsule. I tried this as well but nothing is happening…

Thats the thing… They ARE ticked. And it’s not like the capsule component is in the way either. I tried doing it from the other blueprint but I can’t find a way to cast to the mesh itself.

By default the mesh doesn’t generate hit events. If you want it to then you need to enable Simulation generates Hit events under collision on the mesh
