This is just a wild guess, cause I remember having a similar sounding problem like a year ago… But I had to add an Execute Console Command to my Event BeginPlay that runs “stereo on”, in order to get VR working in one of my projects that I tried to turn into a standalone package. Not sure if that’s still necessary, or if they already include it in the UE4 templates these days. heh but sometimes it ends up being something small like that.
