# Meta XR Mixed Reality Utility Kit (MR Utility Kit, MRUK, com.meta.xr.mrutilitykit)

The Meta XR Mixed Reality Utility Kit (MR Utility Kit, MRUK) is a Unity package that provides high-level tools on top of the Scene API for building scene-aware Mixed Reality (MR) experiences. It is designed to be used in conjunction with the Meta XR Core SDK.
It handles scene data loading and querying, spawning prefabs on real-world surfaces, world locking to prevent anchor drift, environment raycasting for instant placement without scanning, passthrough camera access, NavMesh generation from room geometry, and trackable detection (keyboards, QR codes).

Package: com.meta.xr.mrutilitykit
