Moving Physics Objects With Character Controller?

At the moment I have a character and a crate. Both have rigidbodies and are set up in the level. When I play, the crate drops to the ground and settles, but when I brush against it, the crate does not move. How do I get the crate to react to my character?

(Crate has a Mass of .01 and the Character has one of around 500)

Character controller is basically fakey physics - using a rigidbody with it usually just makes things even more iffy

To get real physics response you'll want to use a rigidbody controller with a collider instead

there are a few examples on the wiki:

The CharacterController does not affect other objects through physics. It collides with them, but it is up to you to push the other objects with the Physics Engine.
