I have to say I have been using your VR Template runeberg and with the exception of the controllers being off compared to what the actual controllers are. (You can check by putting the ends of each controller together and then putting the tops together. The tops end up going into each other.
But other then that it is a great start and like you said it being in C++ keeps blueprints super clean and not overly convolted.
Oh and also the project settings need to be tweaked to be between 90 / 120 fps instead of the 63 (something like that) it was at by default.
