Multi-Pass Rendering

[goro]

I am planning to apply the shader to the entire screen just like vfx guys do.

In our project of Augmented Reality, the CG quality is very superior than the HD webcam generated Image. So the image & cg are not going together. Our vfx guy suggested us that we have to separately make CG blur and add some post rendered effects on it; we have to separately enhance the image quality of Webcam output and then marge both.
