Title: Disabled Camera not clearing from the screen when NGUI is used
Post by: yohann on August 20, 2013, 07:55:44 PM

(SEE ATTACHED IMAGE) I have two cameras, sort of a picture-in-picture, except I want to toggle between full screen and a "windowed" screen. I'm making the windowed screen via the camera.pixelRect property. This works fine...until I add an NGUI element, at which point the disabled full screen camera doesn't clear the image from the screen after it's disabled. Please please help.

EDIT: I've discovered that I can fix this by changing any of the values of Normalized View Port Rect of the NGUI camera by some insignificant amount, such as changing the W param from 1 to 1.001. This gets it working, but I'd sure like a non-hacky way of solving this. Any ideas?

Eh? You must have at least one camera clearing color in your game. UI camera clears only depth by default.

Thanks for the reply! I'm new to Unity, so can you tell me: is this a requirement just of NGUI or is it a fundamental game design concept using Unity?

Fundamental necessity of any game.

If you don't clear the color, how can you expect the stuff you drew previously to go away?
