So, how this object responds to others trace channels we can define as ignore, overlap or block. And how this object responds to others object channel we can define. We can also make our own defined Collision Responses. So we might make a “PickupRaytrace” for this object, then define it on the other objects in the scene. Would need to set a default define check, since there are many objects in a scene, then we only have to change it per object that we want to pick up.
