By default the Leap Motion is set to VR optimized tracking (Leap Mode VR), if you want to use it for this mode nothing needs to be done. The *LeapDesktopActor *expects the leap motion sensor to be used in the non-default desktop mode where it is facing up. It prepares the leap sensor for this by changing the optimization mode to Desktop on begin play and then resetting it back to VR mode on end play. Because of how it works, if you want to use the leap motion in vr, don’t use this asset anywhere in your map!
Instead you should be using LeapHandsPawn or it’s child actor *BSLowPolyHand *in a pawn of your choice.
