I have created a room and two windows on one of the walls. What is the best method to make the landscape behind those windows thus if I take a various position in room lansdcape will be scrolling (it’ll be realistic ), but I want that landscape is only one image

thanks for any help

Just put a large poly behind the window with your pic on it. Put it far enough away from your window so when you move from side to side, it looks decent.

Maybe not the best solution, but a simple one.
