I am trying to create wall art for optical illusions (e.g. person stands close to the edge of a canyon when in reality it's just painted on the floor) with Blender, but since I am a complete newbie I don't really know the best way to do this.
Currently I have the camera positioned at a spot where the actual camera in the room would be and a plane with extruded edges to create the walls and subdivided it.
Now I am struggling to get the image onto the plane so the parts of the image ending up on the floor would be in perspective.
Important: I also need to export each side of the plane (e.g. back wall, side wall, floor) separately so it can be printed out accordingly.
