Hey-ho im here for more stupid questions. I make a connected wall. Then - shift-up copy of house. Then make it as a roof. And for vision trough all that was i find is Fade section in object SideBar. It makes small round "window" but in original game - inside houses roof simply disappears. How can i do this?
