I'm sifting through all of the resources. A first glance it looks like the Unity VR Sample doesn't have the Oculus Utilities imported. Did Unity not use the Utilities? Or modify them under their own namespace? Use their own? What's going on with that? Thanks.
The Unity VR samples package only uses the native VR support functionality provided through Unity. If you want to extend that functionality, you need to import the Oculus Utilities separately.
