How to enable Hand Tracking and Controllers at the same time for a Unity Project

The Quest can operate in controller mode or hand tracking mode, but not both at the same time. What you want to do should be achievable, by placing controller models in the world at the last known location when tracking switches to hands. You’ll have to keep track of real world vs. VR position/orientation changes as the player moves, performs locomotion, re-centers, etc and update the in-world controller placeholders accordingly.
