I'm working on a unity program in VR using Leap Orion 4.0.0, Unity 2018.2, Steam VR , and HTC VIVE. Everything worked just fine until a recent computer clean up where some files were deleted. I suspect something important to Leap was deleted too, because since then, when I try running the program, the hand models (LePoly Rigged Hand Left/Right nested in a Leap Rig) become inactive. If I activate them manually, while they show up in the game, they are just static, and can't be controlled by actual hand movements.
Leap itself does work, as I saw in the Diagnostic Visualizer. After re-downloading everything, reinstalling Orion, and re-importing the assets (core, hands, integration), nothing changed and I am still in square one. Any help? Happy to give out any other information needed.
