How do i anchor a virtual space in the physical space? We are just starting out with Unity and probably have a simple question. We've created a room and we want the open end of the room to always point in a certain direction in the physical environment. The idea is that you sit in a virtual room and see the musicians in the physical room. At the moment, the room is always in a random position, aacording to the position of the headset. Any ideas? We're using the HTC Vive XR Elite. Thanks C
