OVRPlayerController is offset from camera rig

Please, let me know if there is simply a completely different way to do smooth locomotion these days, but anyway...

Using v41, if I import a sample rig, then add OVRPlayerController, it works except it is not following the HMD. So my collision capsule stays in the center of my guardian basically. I see various references to this in a few other threads but nothing for the past two years or so. 

How do you use OVRPlayerController correctly? Do you still need the Camera Character Constraint script added?
