Unity Plugin 6.4.0

• Tracking contains stable content including Core, Hands and the Interaction Engine.
• Tracking Preview contains experimental/pre-release content.

Headline features of 6.4.0 include:

Added

• Pinch To Paint example scene
• Explanation text to all XR example scenes
• Turntable and Pullcord example scene
• Locomotion teleportation system and example scenes in Preview Package

Fixed

• Android Manifest auto-population when building for OpenXR always adds permissions
• OpenXR finger lengths wrongly include metacarpal lengths

Known issues

• Offset between skeleton hand wrist and forearm in sample scenes
• Outline hands aren't displaying
• Scenes containing the infrared viewer render incorrectly on Android build targets and in scriptable render pipelines such as URP and HDRP.
• Interactions callback scene allows blocks to be moved without doing a grasp pose.
• Capsule hands don't have a joint colour in HDRP
• Use of the LeapCSharp Config class is unavailable with v5.X tracking service
• Repeatedly opening scenes can cause memory use increase
• Currently the Ultraleap Hand Tracking feature for OpenXR requires the New and Legacy input systems to be enabled, to simultaneously use OpenXR and the Ultraleap Unity Plugin's features.
• The OpenXR Leap Provider does not currently support the Confidence hand property (and will return fixed values)
• If using OpenXR with OpenXR package imported, when using Unity 2020 and Ultraleap Tracking Plugin via .unitypackage, an error will appear on import relating to HandTrackingFeature. This has been fixed by Unity on Unity 2021
  • A workaround is to right click on \ThirdParty\Ultraleap\Tracking\OpenXR\Runtime\Scripts\HandTrackingFeature.cs and select 'Reimport'
• DrawMeshInstanced error log on certain Unity versions when using Capsule Hands. Unity Issue Tracker
• After using Ultraleap OpenXR in Unity Editor, the tracking mode of device 0 will be set to HMD until the Unity Editor session ends. This can stop the testing of non-XR scenes until the Unity Editor is re-opened
