APlace.Pitch = p;
APlace.Yaw = y;
APlace.Roll = r;

HeadControl = SkelControlSingleBone(Mesh.FindSkelControl('HeadControl'));
HeadControl.bApplyRotation = true;

}

Installation basics:

1) Download the new UDK from the Oculus Developer site.
2) Go to the folder C:\UDK\UDK-2013-03\UDKGame\Config\ and edit the UDKEngine.ini, (back it up first of course)
3) In the [Engine.Stereo3D] section, change the bEnabled parameter = True
4) Optional: in the [Engine.Oculus] section, change the bEnableHud parameter = False, (as the hud is kind of messed up right now).
5) Run the UDKGame program that installed with the UDK, (should be an icon on your desktop).
