Disable Oculus rotation and position tracking

I need my player to be separated from HMD movement. I followed this link https://wiki.unrealengine.com/Oculus_Rift_Separate_View#See_also but I got a bad result. While moving the HMD, the camera moves for a while in the HMD direction and later on resets it back to starting point. What I need is that it doesn’t follow at all HMD movement.

The position tracking is build in and you’ll need to hack into the engine code (somewhere like GetEyePoses()) to get rid of the offset.
