Position of OVRCameraRig

I am just starting out on the MQP and Unity development. I removed the camera, and put in an OVRCameraRig. Set up everything for passthru (not that it matters). In my scene, I have a planet about 0.5 meters deep in Z. I fire up Unity and as I move my head around, with the MQP on it, the planet stays in front of the camera. I would expect it to "stay where it was" and I would be able to "walk around it" and look at it from all angles. Nope.

Is this expected behavior? I have OVRCR "tracking origin type" set to EyeLevel, and "use position tracking" set to checked. Is there something else I'm missing? It's as if it's not tracking position, and all it's getting is IMU updates.

thanks.
