Release Ultraleap Unity Plugin 6.11.0 · ultraleap/UnityPlugin

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.

(Physics Hands) Finger displacement values to each finger
(Physics Hands) Interface based events for easier development
- Please see the updated scripts in the Physics Hands example scene for more information
(HandRays) Add methods to invoke handray Frame & State Change in inherited classes
(LeapXRServiceProvider) Use of device transforms from the service when using Default device offset mode. This does not include tilt/rotation

(Physics Hands) Burst compute is now used to improve certain physics calculation performance
- In Unity 2020+ this is used for "hand is colliding" functions only
- In Unity 2022+ all collision functions are handled by Burst
(Physics Hands) Parameters of the hand (e.g. contact distance) are now controlled at the provider level and have adjusted defaults for better interactions
(Physics Hands) OnObjectStateChange event has been replaced with SubscribeToStateChanges
- This is tailored to handle specific Rigidbodies and will only fire when your subscribed Rigidbody is affected
(Physics Hands) Hand and bone states have been improved and are more consistent with expectations
(Physics Hands) Updated example scene with new events and better visuals
(Physics Hands) Updated PhysicsBone IsObjectGrabbable calculations to use the closest point on the bone to the hovered object
(Physics Hands) Improved Physics Hands grasp helpers to take into account grabs where bones are facing each other
(Locomotion) Expose teleport anchor list & last teleported anchor
(Locomotion) Moved Jump Gems further away from the arm, to account for sleeves
(Locomotion) Added functionality to update the initial position and rotations of the TP anchor after the first Awake

(Physics Hands) Hand forces are reduced when pushing into objects with fingers
(Physics Hands) Stopped physics buttons from rotating incorrectly
(Locomotion) Jump Gems look for audio sources in their children, even if the audio source was set
(Locomotion) If pinched gem was null, jump gem teleport could still be in a selected state
(Locomotion) Teleport ray did not change to an invalid colour when no colliders were hit
(Core) Fixed hands juddering in XR when interpolation is turned off on the LeapXRServiceProvider. Turning off interpolation now turns off head pose interpolation
(PoseViewer) Pose viewer rotation does not match the targets rotation

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.
