0.52.0 Magic Leap Unity SDK Release Notes

SDK Delivered via The Lab 2.0​

  • Unity Example Project
  • Magic Leap 2 Unity SDK Package

Delivered via secure email share​

  • Unity Installer

Features​

  • Exposed Anchors API. Refer to the Anchors sample scene in the MagicLeapUnityExamples project for usage.
  • Exposed Voice Intents API. Refer to the VoiceIntents sample scene in the MagicLeapUnityExamples project for usage.
  • Added support for AprilTags under the MLMarkerTracker API. BREAKING CHANGE: MLMarkerTracker.MarkerType.Aruco, was changed to MLMarkerTracker.MarkerType.Aruco_April.
  • Re-enabled WebRTC support in Unity. We have also added support for FPSHint.
  • Hand tracking has been updated to only start when an app calls 'GestureSubsystem.Extensions.MLHandTracking.SetConfiguration()'. This is done to save on resources and only enable tracking if the app is using the feature.
  • Timestamp data is now provided as part of the gaze recognition state.
  • Added MLCamera preview rendering support.
  • Added a utility UI under Project Settings > Magic Leap > Manifest Settings to help include required permissions in the app's AndroidManifest.xml file.
  • All native libs shipped with the SDK package have been marked to work on the Android x86_64 target and all platform code wrapped under #if UNITY_MAGICLEAP || UNITY_ANDROID in preparation for bringing Relish under the Unity Android platform umbrella. Developers building their own native libs for Relish or using the UNITY_MAGICLEAP preprocessor flag are advised to update their library setup and code accordingly.

Bug Fixes​

  • Fixed issue with Manifest Settings throwing error on first access.
  • Fixed MediaPlayer Stop functionality.
  • Fixed MediaPlayer local playback.
  • Fixed C-API enum mismatch in GazeRecognition API.
  • Updated WebRTC API to support deprecation of distinct MLMRCamera class.
  • Updated MagicLeapController/isTracked input action binding to be a passthrough instead of a button for better detection of connection status at scene startup.
  • Fixed using the PlayerInput component for Magic Leap Controller events.

Deprecations & Removals​

  • Eye tracking calibration status has been removed.
  • WinkLeft, WinkRight, Push & Pull behaviors have been removed from the MLGazeRecognition API.

Known Issues​

  • WebRTC: local video rendering does not work when using native buffers.
  • WebRTC: using app-defined video source with CPU buffers and YUV frame format sends black-and-white frames (awaiting platform support).
  • Eye blinking state is not reported either by the eye tracking api or the gaze recognition api (awaiting platform support).
  • Eye pupil size is always reported as 4.0 (awaiting platform support).
  • Labdriver is run even when MagicLeapLoader is not selected in XR Plugin Management.
  • Launching / terminating ZI after having played 1 editor session already, is not picked up by Unity and it continues to assume the original state of ZI for subsequent plays.
  • Media player render with a small grey-block at the bottom.
  • MLMarkerTrackerDecodedBinaryData restricts data size to 100.
