Help with 2 Cameras

The left side/camera does not move. it just stays the same.

Do you have the mouse look or fps control component attached to the left camera?

You might still have a 'Main Camera' from a default scene. Delete that.

I've always wondered how it would be to see like a chameleon.

You have to make the FollowOrientation parameter of the OVRCameraController set to your First Person Controller. You may also have to make some edits to the script, see this thread:

Also moved to the Unity section since it's a Unity question.

I also have question about 2 cameras. I've bought Universe Sky component, in deffered lighting mode, in order to sort depth correctly, I need to render it to separate cameras with its own culling mask.

So, I clone 2 default Oculus Rift cameras, parent them to original ones to have 100% match, set original cameras depth mode to Depth Only, new Cameras to Skybox, and correct culling masks.

But when I start the game, I get many errors. I suppose, default Oculus camera script is ment to work with 2 cameras only, I can not attach it to additional cameras like that?

Well deferred rendering is only partially supported, so I am not surprised you are having issues. I recall some people had setups with multiple OVRCameras, but I can't remember the exact steps needed to get it to work.

Hmm well I guess I'll wait for future Unity integration releases, meanwhile focusing on something else. I can see there is deffered rendering patch in neighbour thread, maybe it will get merged with original code soon.
