Does anyone have experience to bind a hand menu to the leap motion hands.
Example: LeapMotion VR Hand Menu (work in progress) - YouTube
I am afraid Leap Motion support is very much biased toward Unity. We also have a device in house and have been experimenting with it. The effort it takes to build a decent menu interaction in UE4 is much higher since you are basically starting from scratch. At least, I am not aware of any ready-made and open source hovercast VR menu project for UE4 you can further build upon.
