OnPostRender is called after a camera has finished rendering the scene.

This message is sent to all scripts attached to the camera.

	// This script lets you enable/disable fog per camera.
	// by enabling or disabling the script in the title of the inspector
	// you can turn fog on or off per camera.
	private var revertFogState = false;

		revertFogState = RenderSettings.fog;
		RenderSettings.fog = enabled;
	}
	
	function OnPostRender () {
		RenderSettings.fog = revertFogState;
	}
