Version 4.8.0

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

  • Hands can change the grabbed object’s orientation
  • Two types of grabbing supported: free (from the point of grab or pinch) and snap (the object picked snaps into the hand)
  • Improvements added to the IEGrab component
  • Two hands grabbing is possible and can change the grabbed object's orientation
  • Autoscaling for the hands model in the tracking data can be enabled
  • OpenXR supported on Vive 3 with UE 5.0

Known issues:

  • Grabbed object released when tracking is lost
  • 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
