Great project! There are few VR projects that are this vast and yet as simple as it can get.
I´m having the same problem as Sky_Shrimp using Vive in 4.24 and Thought this was happening only on vive. None of the commands triggers the actions. I have used a Print String to check the input and it works fine. I have now to check the connections closer to see if I can see anything strange, but it´s odd that is not working for any of the maps.
