Switching between Rift cameras + working example

New post to keep it seperate from the OP.

Okay, after going through various threads, I'm just gonna use this for now:

#pragma strict

public var ovrcam1 : GameObject;
public var overheadcam : GameObject;
var isoverheadcam : boolean;
        
function Start () {}

function Update () {

        if (Input.GetKeyDown(KeyCode.C))
        {
            if (!isoverheadcam)
            {
                isoverheadcam = true;
                overheadcam.SetActive(true);
              
            } else if(isoverheadcam)
            {
// set the main cam as true, just in case something messed up or it got disabled somehow
            	ovrcam1.SetActive(true);
            	overheadcam.SetActive(false);
                isoverheadcam=false;
            }
            
        }

}

It's stupidly simple but seems to be the best workaround at the moment.
Basically what it does or what happens:

The main camera stays enabled, it's just the secondary camera that is toggled.

For this to work, your secondary camera must be higher in the hierarchy than the main camera.
And... that's it really.
