MonoBehaviour.OnPostRender()

Описание

OnPostRender is called after a camera finished rendering the scene.

Эта функция вызывается с частотой фиксированных кадров (fixed framerate), если MonoBehaviour включен. OnPostRender can be a co-routine, simply use the yield statement in the function.

OnRenderObject вызывается после того, как камера отрендерила сцену. do something after all cameras and GUI is rendered, use WaitForEndOfFrame coroutine.

See Also: OnPreRender, WaitForEndOfFrame.

using UnityEngine;

// A script that when attached to the camera, makes the resulting
// colors inverted. See its effect in play mode.
public class ExampleClass : MonoBehaviour

    public void OnPostRender ()

            // simple colored things. In this case, we just want to use
            // a blend mode that inverts destination colors.			
            var shader = Shader.Find ("Hidden/Internal-Colored");
