Mixed Reality Utility Kit - Getting started

• Understand the setup requirements for using the Mixed Reality Utility Kit (MRUK).
• Install the MRUK package via tarball, Asset Store, or Unity Package Manager (UPM).
• Configure a Unity project with the correct permissions and setup for Scene API and Passthrough.
• Test in the Unity Editor using simulated room data or live device data via Meta Horizon Link.

• Set Up Unity for XR development to create a project with the necessary dependencies
• Set up your device to configure and test your project on a headset

• Asset Store: Visit the Unity Asset Store, add the package to your assets, and install it from the My Assets pane in the Package Manager.
• Unity Package Manager (UPM): Add the following entry to the dependencies section of your manifest.json file:

    "com.meta.xr.mrutilitykit": "latest", // e.g. "77.0.0"
  
  Alternatively, select Add package by name in the Package Manager and enter com.meta.xr.mrutilitykit.
• Import from disk: Download the package directly from the Meta Developer site and unzip it. In Unity, open the Package Manager, click the + icon, choose Add package from disk, and select the package.json file, located in the unzipped folder.

1. Make sure your Unity development environment and your Meta Quest headset are correctly set up.
2. Create a new Unity scene or open an existing one.
3. Remove the Main Camera.
4. Add the OVRCameraRig prefab or the Camera Rig Building Block.
   • Under OVRManager → Quest Features, enable Scene Support.
   • Under Permission Requests On Startup, check the Scene permission.
5. If you want to see Passthrough, add the OVRPassthroughLayer component to a GameObject in your scene or add the Passthrough Building Block.
   • Under OVRManager → Quest Features, enable Passthrough Support.
   • Under Insight Passthrough & Guardian Boundary, check the Enable Passthrough permission.
6. Go to Meta → Tools → Update AndroidManifest.xml, to ensure your Android Manifest is correctly set up with all necessary permissions.
7. Open the Project Setup Tool (PST) and fix all outstanding warnings.
   • You may find this under Meta → Tools → Project Setup Tool.

• Overview Get an overview of MRUK’s key areas and features.

• Place Content with Scene Combine spatial data with placement logic to add interactive content in the right places.
• Manipulate Scene Visuals Replace or remove geometry, apply effects, and adapt scenes using semantics and EffectMesh.
• Track Objects in MRUK Track keyboards using MRUK-trackables.

• Share Your Space with Others Use MRUK’s Space Sharing API to sync scene geometry across multiple users.
• Debug Your MRUK App Use tools like the Scene Debugger and EffectMesh to validate anchor data and scene structure.
