Hey there. When I start the game (steamVR, PC, Valve-Index) it doesn't show up in VR, although I get sound. When I look onto my PC monitor (in non-VR) I can see the game, but it's just the inside of the initial space ship and when I move my mouse over it, it rotates like crazy. Tried 2 times already, it's always the same. Any idea? :/
