Tilt a room in lua

I can’t for the life of me figure out how to tilt these objects in lua to simulate the world being tilted in a direction. All i can do is either grab the original orientation (they are ghosts or like holos of original props in another room) or tilt them all , but I can’t get them to tilt AND keep original orientation (as in to simulate a room is present in space but now tilted). Any Help?
