A solution that worked for us was posted to the answer hub link above:
I had a similar problem on Oculus only (worked fine on Vive). The Oculus runtime was leaving the loading splash screen up which is black by default. Something had caused the Oculus plugin to not recognize that loading had completed. I worked around it by adding a “Hide Loading Splash Screen” with clear set to true from begin play on the level blueprint. If you are seeing the same problem, you’ll see in the log where the Oculus blacks the screen: LogHMD: FOculusRiftSplash::PushBlackFrame LogHMD: FOculusRiftSplash::Show But then won’t see the corresponding FOculusRiftSplash::Hide.
