I am a published virtual reality game designer for Oculus Rift. I developed Xing: The Land Beyond, a critically acclaimed game for VR. I am passionate about Unreal Engine and have been using it since 2012. I have some Unity experience, enough I believe to successfully do this job for you. Since I think transferring the assets is going to be fairly easy, I will also try to make the results look very good, perhaps going into Unreal's material editor, and do a lot of work on the actual rendering of the final shot in Unreal. If you want any interactivity, I can also help you there. If you want to turn this experience into an app for any platform, I can help you there. I love Unreal, and I would love to work with you. Please reach out to me if you have any questions. Thanks, James Steininger.
