Setting Up Shared Spatial Anchors for Local AR Multiplayer

Shared Spatial Anchors are the key to co-located Mixed Reality. This technology allows two or more headsets to align their virtual coordinate systems based on a shared physical reference point. To set this up, ensure all devices are on the same Wi-Fi network and have granted 'Spatial Data' permissions. One user typically 'hosts' by scanning the room and creating an anchor, which is then uploaded and shared with other participants. This enables experiences like local AR board games or collaborative design sessions where everyone sees the same virtual content locked precisely in the same physical location, creating a truly shared reality.
