Yes!
I'm looking for the scene called 'PassthroughWithTracking' that used to come with the previous Leap Motion core assets (LeapMotion/Scenes/PassthroughWithTracking).
I used to have the passthrough working well on unity 4.6. I recently upgraded my project to Unity5.1.1 and I cant find any way to get the passthrough mode back on the rift!
Thanks again for your interest!
