Oculus Rift DK2. How to show different things in the monitor and Oculus Rift

Hello!,

I have a question about the oculus rift (I'm not sure if my question is a little bit stupid, I'm sorry if it is).

I want so show different things in the monitor and in the oculus rift. Now I'm using the mirroring because I want to show the same in both devices but one particular gameobject only in the monitor (this gameobject have a specific layer for the "culling mask" of the oculus rift cameras) but I don't know how to show it only in the monitor.

Excuse my bad english. Thanks a lot!.
