Hi first of all i am new to this so dont blame me 
I want to hear if its possible to make a VR game in rl so u fx can set a camara on your VR helmet and change the real skybox?
Well, if I had any clue of your fancy shortcuts this would be easy to answer. You can surely setup the skybox whatever you like, with the rotation. This rl-u-fx stuff just gets you ignored as your audience of understanding is limited.
