Camera rendering

Is there a way to directly control what each player's camera in a scene can render? I need it to be object specific, not layers. So as of right now I have been turning the renderer off on the object, but that isn't going to work because different camera see different things. How can I control what specific objects each camera can see?

I would recommend layers, or just using an image effect that masks everything except for an object selected as a public variable.

 

Yea I am going to give layers a shot. After looking through the API I see now that you can re-assign layers by script which I think will work in my case. Thanks for the response!
