Hello,
The plugin is really great, Thank You! 
im having problems with LeapPassthroughCharacter, it looks like if ipd would be off and also the warping, it is very uncomfortable to open both of my eyes, an illustration of how left hand looks when im holding it right in front of me:
I have tried ‘R’ to reset position, adding optimizeForHMD Blueprint (checking/unchecking the options), setting boolean - ‘Leap Facing Mode is HMD’ inside LeapAnimBodyConnectorWithPassthrough and changing Sprite location inside the Viewport, messing with ‘LeapPassthroughPostProcess’ Material values, but haven’t found a way to influence the eye offset. What could be the problem?
Using the latest plugin version 0.9.7, UE 4.9.2, Leap Software 2.3.1
