Camera viewport

I'm trying to set the camera viewport at runtime to visualize whether inputs are allowed or not. This works great inside unity but as soon as I build a binary the borders in the smaller view aren't black. It seems that the video-buffer doesn't get cleared.
Is there any workaround?

 

Hi.

You can use an additional camera to clear the screen. Set it up with culling=nothing and a depth lower than your main camera.

Thank you that did the trick.
