Version 4.7.1

This version supports Gemini 5.2.0.0 and greater LeapC.dll (Gen2 support) and Unreal v4.27, v5.0 and v5.1

  • Support of OpenXR hand tracking on windows
  • Fix to bug in android devices where the tracking will be disconnected when the system goes to sleep
  • Fix to bug in android devices where hand tracking does not resume following device disconnect then reconnect whilst running an app
  • Fix to laser pointer interaction with UIs
  • Fix to chirality of Ghost and Mannequin hands

Known issues:

  • Text colour in UI interaction drop downs wrong (UE5 bug)
  • In UE5, grabbing with the right hand motion controller is intermittent
  • HMD offset is not set automatically for SteamVR devices and should be set manually for your headset in the IEPawnHands blueprint.
  • As with most Unreal 4 VR projects, when run in VR preview in the editor, full framerate is often not achievable. This is fine when packaged.
  • Auto calculating orientations with imported meshes that have negative scales require manual correction to the PreBaseRotation.
  • With multiple leap device setups where one is Screentop, the screentop device position can be offset vertically
  • With multiple devices, when rapidly plugging between devices, a ghost duplicate/inactive device can be detected
  • FingerExtended is not used in Pose Detection scene
