Leap motion relative positioning

Hi guys,

I have an orion dev kit and have been playing around with the official Unreal leap motion plugin. Using just the LeapMotion rigged hands/echo pawn I can quickly get a pair of rigged hands working in my field of view. I’m trying to do some tracing from the fingers straight out and am having trouble translating the coordinates returned by get position tip to the actual coordinates of my finger in world space.

What is the correct way to do this? Getting the leap controllers relative translation and adding it to the position return by get position tip is not accurate. I followed the github plugins howto, but that doesn’t work reliably for me either. Any hints appreciated.
