I am trying to create a simple Unity application that uses the Hover-VR-Interface-Kit for a head-mounted leap motion controller. I followed the tutorial provided in order to integrate the hovercursor and hovercast. Once the application is running, the hovercast menu does not appears and a have the error messages arise:
MissingMethodException: Method not found: 'Leap.Frame.get_IsValid'.
Leap Motion Orion 3.1.3
Does someone knows how to handle this issue?
