2d plus depth

Hi to all. I need to create a two camera system for using with a Philips Dimeco TV.

The first camera use the actual Unity render, but in the second one I need to create a deep image, I tried making a shader but only could work with a plane, but no rendering on the camera.

What do you mean “deep image”? Do you mean you need to create perspective for a stereoscopic camera?

I need to generate something like this:

The first camera render the scene as always, but the second need to reneder the depth objetcs from the camera.
