How do I move forward & raycast based on the MainCamera direction (in UFPS)

Hello, I'm having trouble editing the UFPS Scripts to work with Google VR. I have the "Advanced Player" with a "GvrViewerMain" attached to the MainCamera. Everything works fine, except, when I use "Alt" to "simulate head movement", the Player does not move forward or Raycast in the direction of the Camera.

How do I "Move Forward" & "Raycast" from the center of the Main Camera with the "UFPS Advanced Player"?

I've been stuck on this for weeks! Some insight would be awesome! Thanks.
