MonoBehaviour.OnRenderImage(RenderTexture,RenderTexture)

説明

OnRenderImage はすべてのレンダリングが RenderImage へと完了したときに呼び出されます。

ポストプロセッシングエフェクト

It allows you to modify final image by processing it with shader based filters. The incoming image is source render texture. The result should end up in destination render texture. You must always issue a Graphics.Blit() or render a fullscreen quad if you override this method.

When there are multiple image filters attached to the camera, they process image sequentially, by passing first filter's destination as the source to the next filter.

このメッセージはカメラにアタッチされているすべてのスクリプトに送られます。
