Camera issues

[luggage]

Hello again.

So I've added a button and a couple of text labels, that's all working ok.  The button loads the game ok.  I want to set a background screen on my main menu scene (the one with NGUI).  I've dropped the asset on and it's created a Sprite Renderer, it all looks ok in the scene view but when I hit Play I don't see my background.  Is there a way to fix that?  Sorry, it's probably really obvious but I'm trying to learn Unity and NGUI at the same time.

My hierarchy looks like

UI Root
    +Camera
    +Button
    +Label
Background.

Doesn't seem to matter where in the hierarchy it goes I don't see it.  It's position is set to 0,0,0.

Any ideas? Thanks!

Why is the background outside the UI root? Sprite Renderer implies Unity UI, not NGUI.

Thanks for the reply, sorry for the delay, have been away and only just got back to this.

I sorted it out, stupidly I hadn't added a normal camera to get the non-ngui elements rendering. 

Thanks!
