• 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.

• 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 workarond is to right click on \ThirdParty\Ultraleap\Tracking\OpenXR\Runtime\Scripts\HandTrackingFeature.cs and select 'Reimport'
