MonoBehaviour.OnRenderImage(RenderTexture,RenderTexture)

Description

OnRenderImage вызывается после того как весь рендеринг для отрисовки изображения завершиться.

Эффекты постобработки (только для Unity Pro).

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.

Это сообщение отсылается всем скриптам прикрепленным к камере.

Android: Use the Android Player Settings to make changes. Select the Use 32-bit Display Buffer option to use a post-processing effect with the alpha channel, or experience Banding Effects. The alpha channel is not available in a 16-bit Render Texture.

        // Copy the source Render Texture to the destination,
        // applying the material along the way.
        Graphics.Blit(src, dest, mat);
