Ultraleap Unity Plugin 6.12.0

• This release was tested against Unity 2021LTS and 2022LTS
• Tracking contains stable content including Core, Hands and the Interaction Engine.
• Tracking Preview contains experimental/pre-release content.

Headline features include:

Added

• (MRTK Support) Added an MRTK3 subsystem for using Leap tracking directly (non-OpenXR)

Changed

• (XRHands) XRHands subsystem will now use existing LeapXRServiceProviders found in the scene before considering generating new ones

Fixed

• (XRHands) XRHands double-translates tracking data causing XRI InputActions to be wrongly positioned when the XROrigin is moved

Known issues

• 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)
• 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
• The OpenXR Leap Provider palm can be in unexpected position when using pre-1.4.3 OpenXR Layer. A workaround is to ensure you use 1.4.3 or newer - installed by the 5.12.0 or newer Tracking Service Installer
• Running both the Ultraleap XRHands Subsystem and another XRHands Subsystem at the same time causes unstable results. Only enable one at a time.
