My object bounce with 0 bounciness

Unity Engine

I had set my physic material become 0 bounciness,
but my object still bounce in little movement,
how to make it not bounce?

I think you can use a OnCollisionEnter function to end the current velocity.

rigidbody.velocity = Vector3(0, 0, 0);

Also look for the other PhysicMaterials parameter, especially the bounceCombine Parameter.
