Using HMD other than Oculus Rift (Have 2 active camera rendering to half of screen)

Right now, we have started a project using high-end HMD but don’t know how to get it work with unreal. Basically what we want is exactly as the Oculus rift plugin does without the distortion correction, which seems very straight forward: just define two camera and have each of them render the scene onto half of the screen. But since I am new to Unreal Engine, I find it very hard to do it. The only naive way I can come up is initialize the game with two player and make the game running on split screen… which is definitely not the ideal way…

Any suggestion and guidance will be appreciated

Did You come with some idea how to do this? Have two active cameras at once?
