If I drop in LocalAvatar, I see the hands and controller avatars fine and they follow the hand movement. I can also get the rotation and position of the controllers with code no problem.
However, if I drop a gun model as a child of rightHandAnchor or RightControllerAnchor in OVRCameraRig, when I play the game in the headset the gun model is fixed in place. I have tried with the LocalAvatar at the same time and the avatars move, but the gun model is fixed... also tried without the LocalAvatar.
I made sure this was in the manifest: <uses-feature android:name="android.hardware.vr.headtracking" android:version="1" android:required="true" />
