    Hi, is it possible to extract all lightning and shadows from 3D scene, convert it to 2D and display it ontop of sheet? Maybe with adjustable opacity?

    There are shaders that can do this... I think things like ScreenSpace Ambient Occlusion (SSAO) might give you a jump on it. You could also stage up white objects and render it to a RenderTexture, then put that in front of your camera on a card or canvas or something.

    I don't see any connection between that API and your original question, but I could be wrong. You want to definitely get familiar with the basics because it will help you reason about what you're trying to do.

    Can I make a scene with ScreenSpace Ambient Occlusion (SSAO) to be somewhat transparent, adjust opacity. Then do something like in this movie?

    RenderTexture is definitely what you'd want for the final output, though am not sure how to get everything you want from the scene into it.
