Hey
I didn't test a proper interaction, coz I don't need it, but it works with the leap UI buttons, with the colliders/physic objects and that's enough for me. I think it should work with the interaction engine too. Currently I'm creating a second hand in the runtime, adding it to the pool of hands for processing and state it is left (or right, if we spot a left one). As for position, I used Leap.TransformedCopy cast.
