Physics.OverlapBox doesn't detect collision with Character Controller

Unity Engine

Hi! I’m using OverlapBox to detect if any object is occupying a certain space, it works great for objects that have a box collider, but it doesn’t detect objects that have a Character Controller.

Does anyone know why it doesn’t detect Character Controller?

            var numOverlaps = Physics.OverlapBoxNonAlloc(position, Vector3.one * 0.45f, overlaps, Quaternion.identity, ~(1 << LayerMask.NameToLayer("Terrain")), QueryTriggerInteraction.Ignore);

OverlapBoxNonAlloc finds colliders, not CharacterControllers.

It should, as CharacterController contains a Collider - so it is expected by the developer.
But the fact is above. So the solution: add a small collider to your character.
