I'm able to import the LM Core into an empty 2017.2.0f3 project and see my hands in the editor view without any problem. However, I don't see anything in my headset. This is true for any of the sample scenes I try (which use the LMHeadMountedRig prefab). The LM controller itself seems fine so it's probably something within Unity.
Am I using an incompatible Unity version or something? Thanks!
