You should be able to use the same technique, but you may have to get the child actor which holds the raw hands themselves for collision. E.g. in rigged floating hands you have two skeletal meshes, which may need collision checks for the interface to work. Let me know how this works out so I can add the complete solution to documentation.
There are currently no Mac compatible HMDs so supporting VR for Mac at the moment wouldn’t serve a purpose; but I did also check the latest Leap Motion SDK resources and they still have Orion as windows only =/. You’re best bet would be to use the 4.10 plugin which has the v2 tracking.
