Leap Motion Unity Error

[CrazyGordon]

Dear Sir or Madam,
When i use leap motion to build some demo, it always run the following errors:
INPUT AXIS NOT SET UP. Go to your Input Manager and add a definition for LeftVRTriggerAxis on the 9th Joystick Axis.
INPUT AXIS NOT SET UP. Go to your Input Manager and add a definition for RightVRTriggerAxis on the 10th Joystick Axis.

The two packages I used:
Leap_Motion_Core_Assets_ 4.4.0.unitypackage
Leap_Motion_Interaction_Engine_1.2.0.unitypackage

Could anyone can help what's happen and how to resolve it?
Thanks a lot.
Best wishes,
Gordon

You don't need to use Unity's Input Manager for a Leap Motion project.

Same issue here. Happen with the last version (4.4.0 Core and Interaction Engine 1.2.0). In the scene also I have a HTC (Unity SteamVR plugin).

The previous version worked ok.

The complete trace exception is

INPUT AXIS NOT SET UP. Go to your Input Manager and add a definition for RightVRTriggerAxis on the 10th Joystick Axis.

Spoke with someone smarter than me, and it seems I was wrong! The error is there to tell you to go to the Input Manager and set up axes for using Oculus and Vive controllers with the Interaction Engine examples. See the docs regarding InteractionXRControllers: https://leapmotion.github.io/UnityModules/interaction-engine.html
