Collision detection not working in VR mode

When I am using my scene in VR mode, it’s not available with collision to wall or any of objects. It’s there got any way to enable it? if not I will walk to outside the scene.

The collisions in the VR mode are off, so that the camera movement always matches your head movement. If your head moved while the camera did not it could cause motion sickness.

If you move through the scene using teleporting (triggered with the index finger), the teleport won’t allow you to pass through walls, though.
