thanx it has helped, actually i managed to create 2 layers one with mirrored scene, and i set parent to one (i didnt know what is it for this parent 🙂 ), and i wanted to describe my next problem, but i finally! found what are these layer controls for (bring layer to front, or send him back) 🙂
many thanx, it seems so as i am coming deeper into (for me still) mysteries of this tool 🙂
