MonoBehaviour.OnPreRender()

Описание

OnPreRender вызывается перед тем, как камера начнёт рендерить сцену.

Эта функция вызывается с частотой фиксированных кадров (fixed framerate), если MonoBehaviour включен.

Note that if you change camera's viewing parameters (e.g. fieldOfView) here, то они вступят в силу только в следующем кадре. Сделайте это в OnPreCull вместо того. OnPreRender can be a co-routine, simply use the yield statement in the function.

Also note that when OnPreRender is called, the camera's render target is not set up yet, and the depth texture(s) are not rendered yet either. If you want to do something later on (when the render target is already set), try using a CommandBuffer.

See Also: OnPostRender.

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