Box falling through platform

Unity Engine

I make a cube with rigidbody and psychics material but whenever I test it, the box doesn’t bounce. It just goes through all platforms. Why is this happening?

Hi,
Your Cube with a Rigidbody only have a BoxCollider, which is a Trigger. So that’s expected behaviour.
