How can I display game as new scene on a plane with background from previous?

My point is to interact in 3D world with portable console and play simple 2d(e.g catch fruit) game. I know I should use scene.loadleveladditive, but the problem is with displaying it on this small object with background from previous scene.

I solved it by myself, render texture is making whole job. Just need to remember to Load.Scene additively and also of unloading the new scene.
