There was a while back a flag that could be set but that feature got disabled a while back. Would be good to reintroduce that now that the first framerate improvement update has been released, just about everyone will be getting the required 75+ fps on above average machines. And by the time that the CV1 is released next year we'll also have seen the DX11 update come and gone which will increase the framerates further.
All the dev team would need to do is add a separate camera for VR the same way that Unity and Unreal do.
Native Oculus/Vive support will be a good selling point imo for both the engine itself and games released by the likes of us.
