0.52.2 Version 1 Updates​

  • Adjusted Handtracking Pointer position based on aligning with other platforms

Known Issues Being Worked On​

  • Handtracking Performance issues when interacting with other objects, recent updates should have improved this.
  • To use the simulator when running MRTK, you must set the Script Changes While Playing setting to Stop Playing and Recompile or Recompile and Conintue Playing in the Unity Preferences
  • When playing in Editor errors with ImageTracking on start and Configuring HandTracking on stop show in the logs, these do not cause issues and will be removed in future releases

Deprecations & Removals​

  • Deprecated Configuration Files have been fully removed

Important Notes​

  • Instead of copying a configuration file, clone the DefaultMixedReality version and make adjustments. We have found copying an MRTK configuration file can cause issues such as Input Data Providers not loading or visualizers not attaching properly
  • Controller Visualizer sometimes stops positioning and the logs say: Left_ControllerModel(Clone) is missing a IMixedRealityControllerVisualizer component! This happens sporadically, we have found adding the MixedRealityControllerVisualizer component to the model itself resolves this.
  • If you application builds and results in a blank/empty scene, you must adjust your projects quality settings. (Known issue in editors 2022.2.a16 and older) To resolve this, remove all but one of the quality presets in your projects quality settings (Edit>Player Settings>Quality)
  • Developers can remove the feature by commenting out line 276 in the MagicLeapMRTKController.cs script.
