I found exactly what I was looking for (see link below!). I have configured Unity so that I can create VR scenes for my Oculus-Go. But I would rather work with Blender, because I know much about the Blender-toolset. Unity is a top tool, but still a proprietary software unlike Blender. Also, I couldn't install Unity on my Linux system, so I have to use it with Windows (Windows doesn't run so smoothly on my PC compared to Linux on the same machine).
