Transform + duplicate a camera view?

Unity Engine
1

Hi guys,
I have this project where I would like to have my app’s camera view displayed 4 times around the centre of the screen. Something like here

I have this script used for flipping my camera view

function OnPreCull () {
    GetComponent.<Camera>().ResetWorldToCameraMatrix ();
    GetComponent.<Camera>().ResetProjectionMatrix ();
    GetComponent.<Camera>().projectionMatrix = GetComponent.<Camera>().projectionMatrix * Matrix4x4.Scale(Vector3 (-1, 1, 1));
}
function OnPreRender () {
    GL.SetRevertBackfacing (true);
}
function OnPostRender () {
    GL.SetRevertBackfacing (false);
}
@script RequireComponent (Camera)

But as far as I understand changing/adding Vector3 dimensions wouldn’t do it. What would you suggest?
Thanks!

You could render your scene into a RenderTexture, then use it to texture a quad. Then you can flip the image by flipping the UV coordinates of that quad.
