OVRCameraRig passes through objects when rift connected

I am developing an app using OVR. The problem is that when my OVRPlayerController reaches a wall and hit it, the camera passes through it and i can actually see what is behind, almost as if the wall wouldn't be there. I managed to solve the problem adjusting the camera near clipping plane so that it stays inside the character collider. The problems stays in the fact that when i run the app on screen without the oculus device attachet, it works perfectly, but when i run the app through the oculus (even in build version) it still continue to pass through objects like i did not set the near clipping plane. Anyone has a tip on how to solve the problem??
