Mixed Reality Utility Kit - Trackables

• Explain what a trackable is and how it differs from static scene anchors.
• Grant the Spatial Data permission required for all tracking APIs.
• Enable MRUKTrackables in the MRUK component (e.g., checking “Keyboard Tracking Enabled”).
• Subscribe to TrackableAdded and TrackableRemoved events.
• Instantiate prefabs on added trackables and destroy them when trackables are removed.

• Enable Spatial Data Permission
• In the MRUK component under Scene Settings → Tracker Configuration, check one of the trackable options: Keyboard Tracking Enabled or QR Code Tracking Enabled.

Check either of the Keyboard Tracking Enabled or QR Code Tracking Enabled check boxes. MRUK provides a Trackable Added and Trackable Removed event, where we can easily call our public methods from.

using UnityEngine;
using Meta.XR.MRUtilityKit;

public void OnTrackableAdded(MRUKTrackable trackable)
{
    Debug.Log($"Trackable of type {trackable.TrackableType} added.");
    Instantiate(_prefab, trackable.transform);
}

public void OnTrackableRemoved(MRUKTrackable trackable)
{
    Debug.Log($"Trackable removed: {trackable.name}");
    Destroy(trackable.gameObject);
}

• Overview Get an overview of MRUK’s key areas and features.
• Getting Started Set up your project, install MRUK, and understand space setup with available Building Blocks.
• Place Content without Scene Use Environment Raycasting to place 3D objects into physical space with minimal setup.
• Manage Scene Data Work with MRUKRoom, EffectMesh, anchors, and semantic labels to reflect room structure.

• 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.

• 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.

• MRUK Samples Explore sample scenes like NavMesh, Virtual Home, Scene Decorator, and more.
• Mixed Reality Motifs Instant Content Placement.

• Mixed Reality Best Practices Design MR apps that are comfortable, intuitive, and immersive.
