Hi, Max.
Thank you very much. After several attempts I successfully launched my game in stereo mode. And I noticed that you must cook contents for windows before launching this way, otherwise you get an error or have your game stuck at the loading screen.
So I guess this is for testing purposes only, not for deployment.
I have two more questions, if they don’t violate any of your terms 
- Can I deploy my game to be stereo on a smartphone, or other mobile devices, so the player can use his phone (with a joystick maybe) as a simple HMD if he wishes. Of course it’s even better if the player can turn on or off stereo, so he can play the game in 3D or as normal.
- What about other head-mounted devices? They don’t have an official built-in plugin as Oculus does. What should I do if I want to include those devices as a choice for my potential players, or if I want to build my own custom game device for Unreal?
Thank you again.
Pumel.
