Why does my componen not collide with static mesh

Hi,
I have added a second Capsule Collision to my character, which should detect collision with static meshes such as walls (this must be seperate from the Capsule Component for a specific and complicated reason). I have set up the collision exactly like the standard Capsule Component, yet it does not detect collision with static meshes, only with pawns
thank you for helping

Make sure your static meshes have collision set up too, collision is a two way thing

By this - they mean both colliding objects need to have the corresponding object type as generating a collision. If only one body is “colliding”, neither of them will register the collision.

Who are “they”?
