I made a small Quiz game, but on the camera preview it just shows the Skybox. And whem I try to run the Game the screen turns just blue. ;(
Untick the 2D box in your Scene window and take a look at the camera’s clipping planes to make sure your geometry is actually in the camera’s view. Your camera is at z of -1, but where are your other objects?
My other objects are at 0.
