I scan a room with RoomPlan API, then keep the same ARSession running (stop(pauseARSession: false)) and place RealityKit entities using the CapturedRoom wall transforms (wall.transform, wall.dimensions), parented to an anchor at the world origin. The camera position stays continuous, so tracking was not reset. But the entities do not sit on the real walls. The whole room appears shifted.
What is the correct way to place content in the live AR session so it aligns with the scanned room?
