One of the first things you will need to think about when starting to develop any Unreal Engine (UE) powered VR experience to be used with the Oculus Rift is deciding whether the experience will be a seated one or a standing one. In the following tutorial we will take a look at how to setup your UE projects VR camera for a standing Oculus Rift VR experience.
Steps
Below you will find instructions on setting up a Pawn to work with a standing Oculus Rift experience.
