How to Walk in the Direction Oculus Rift is Facing but without rotating the character

How to Walk in the Direction the Oculus Rift is Facing but without rotating the character?

i’ve followed this guide but it just detaches the Camera from the Character, but anyway, it doesn’t really work in 4.7, it ruins the 3D view in the oculus, the eyes offset becomes wrong so the two renderings do not blend into one correctly.

i’m either looking for a way to fix that code or a new approach.
