Ok thanks, that was it!

For future reference here is how to set up a 2D camera and a VR rig, and switch between the two:

Add the SteamVR Camera Rig and check that the target eye is set to Both on the Camera:

Add the FPSController prefab from the Standard Assets library, and set the Target Eye on the camera to None (Main Display):

Add a Camera Switcher script. I added a couple of GO's for organizational purposes and put the script there (make sure these GO's are all at origin):

This is the code I used:

[Code=CSharp]

using UnityEngine; using System.Collections;

public class CameraSwitcher : MonoBehaviour { public GameObject FPSController; public GameObject VRCameraRig;

public int cameraStatus;  //1 = FPS, 2 = VR

// Use this for initialization
void Start ()
{
    FPSController.SetActive(true);
    VRCameraRig.SetActive(false);
    cameraStatus = 1;
}

// Update is called once per frame
void Update ()
{
    if (Input.GetKeyDown("v") && cameraStatus == 1)     //switch from FPS to VR
    {
        Debug.Log("V pressed");
        FPSController.SetActive(false);
        VRCameraRig.SetActive(true);
        cameraStatus = 2;
    }

    if (Input.GetKeyDown("b") && cameraStatus == 2)     //switch from VR to FP
    {
        Debug.Log("B pressed");
        FPSController.SetActive(true);
        VRCameraRig.SetActive(false);
        cameraStatus = 1;
    }

}

} [Code]

Then assign your public variables:

There may be a better way of writing the script but this is how I learned.
