Reviews Unity code targeting Meta Quest and Horizon OS for performance issues, rendering best practices, and common VR pitfalls. Use during code review or when diagnosing Quest performance problems in Unity projects.

hz-unity-face-tracking

Drive ARKit-blendshape-rigged head/face models in Unity with the wearer's facial expressions on Meta Quest via Meta Movement SDK (face tracking + A2E). Use when a user has an FBX with the 52 ARKit blendshapes (any prefix, _L/_R suffixes) and wants it to animate from face tracking on Quest Pro / Quest 3 / Quest 3S.

hz-unity-fbx-import

Ensures complete FBX URLs or absolute paths are used when importing external 3D models into Unity projects targeting Meta Quest and Horizon OS. Use when adding FBX files, 3D models, or external assets.

hz-unity-meta-core-sdk

Meta XR Core SDK (com.meta.xr.sdk.core) for Unity XR development. Use when setting up VR/MR projects, configuring OVRManager, adding OVRCameraRig, enabling passthrough, hand tracking, spatial anchors, boundaryless mode, controller input, Scene API, or any Meta Quest XR feature. Covers OVRProjectSetup, AndroidManifest generation, and project configuration for Meta Quest headsets.

hz-unity-meta-mixed-reality-utility-kit

Meta XR Mixed Reality Utility Kit (MRUK) (com.meta.xr.mrutilitykit) for Unity XR development. Use when working with Scene API data (rooms, walls, floors, furniture), spawning prefabs on scene anchors, placing virtual objects in the real world, world locking to prevent anchor drift, raycasting against room geometry, generating NavMesh from scene data, environment depth raycasting for instant placement without scanning, Passthrough Camera Access (PCA), trackable detection (keyboards, QR codes), destructible scene meshes, space maps, room sharing for multiplayer, or any MR scene-aware feature.

hz-unity-meta-movement-sdk-retargeting

Set up and tweak Meta Movement SDK (MSDK) retargeting for a character model. Use this whenever the user wants to retarget a humanoid FBX/prefab for Meta Quest body tracking, generate a retargeting config, or hand-edit the resulting `<asset>.json` (fix known-joint mappings, exclude joints from auto-mapping, rename target joints, adjust per-joint mapping weights, change a mapping behavior to twist/childAlignedTwist, edit T-pose values). The headless entry point is `Meta.XR.Movement.Editor.MSDKUtilityEditor.RunDefaultRetargetingSetup(GameObject asset)` — call it via Unity MCP first, then hand-edit if needed. **Skip** if the user is editing runtime retargeting code, the source `OVRSkeletonData.json`, or non-MSDK files.

hz-unity-meta-quest-ui

Use when capturing the passthrough camera image/texture, reading the camera pose and intrinsics, projecting camera pixels into world space via `PassthroughCameraAccess.ViewportPointToRay`, wiring camera frames into ML/CV models, or reasoning about resolution, permissions, vendor tags, and the pinhole/principal-point model. For projecting the image onto a flat world-space surface (frustum-slice quad / image-plane overlay) see references/principal-point-offset.md; for placing 2D ML detections as world-space 3D bounding boxes see references/detection-bounding-boxes.md. Skip if the user only wants to cast the user's POV (use the Media Projection API instead) or is doing screen-space-only overlays.
