Rigidbody will overwrite children colliders, and collision events won't run.

So... I have an entity, and it has 6 hitboxes (cube-collider, is not trigger and children of entity) what detects the gun bullets. It works fine but I want to add to my entity Rigidbody. And if I make this, the hitboxes won't detect the collision and the bullets glance off from the hitbox.
