Infinite motion and bounciness inside a closed room.

    I am trying to create a 3D world which contains objects(sphere collider) in constant motion inside an enclosed room (made of walls of box colliders).

    I need the objects to bounce off the walls and off each other infinitely.

    I apply a force at the Start() of each object. The "Use Gravity" is set at false for all objects and walls. The walls are "Is Kinematic".
    There is a physics material for objects and walls where friction is 0 and bounciness is 1.

    The problem is that the objects strike the wall and don't bounce at all, rather they slide along the wall and stop.

    Kindly help.
