3.0.3.2R

2026-10 · package 3.0.302 · first release · for AR 51 Unity SDK 3.0.3.2R

Requirements

• AR 51 Unity SDK 3.0.3.2R and its Meta Quest (Meta XR) package.
• Unity 2022.3 or newer; Meta Quest 3, tethered (Quest Link) or standalone.

New

• Automatic alignment. HeadsetCalibrator lines up the headset's world with the AR 51 capture space while the wearer moves — no button or poses — and recovers by itself after a headset recenter or a loss of tracking.
• Wearer hints. State, Hint, StateChanged and HintChanged let your app tell the wearer what to do ("walk a few steps", "hold still").
• Hint panel. CalibrationHintPanel is an optional in-headset panel that shows a hint only when the wearer can help, with editable texts.
• Prefab. The Headset Calibrator prefab combines the calibrator and the hint panel — drop it in your scene.
• Calibration Demo sample. A ready scene with two small example scripts, installable from Package Manager.
• Demo apps. Ready-to-run builds for Windows (Quest Link) and Quest standalone on the download page.
