I am using the UIWidget to set my UI size to "full screen" with the anchor settings.
As you can see from the picture I set the four margins to be zero but however i see nothing in the Game View because the size on the UIWidget is 2*3172.
But when I play the scene, the size is fine, UI is there.
Anyone know how to fix this? It is troublesome that I cant preview the UI

Thanks
[Solved] There should be only 1 camera to draw the NGUI layer
