During the course of writing this book, the HoloToolkit had a few major revisions. One such major revision was the HoloLens Camera prefab. In the last chapter, we made our own camera from scratch. While this still works technically, the new prefab allows much easier testing inside Unity. Let's set it up real quick:

             1. Delete the MainCamera object from the Hierarchy.
             2. In the same directory as the InputManager prefab in the previous section, there should be the HoloLenCamera prefab.
             3. Drag it from your Project view into your Hierarchy and drop it.
