Basically we have checks in place to see which HMD is being used and then certain functions are run based on what HMD is returned. Without warning the Oculus HMD isn’t being read as the Oculus HMD. It’s showing up as Steam VR (in packaged builds) but in editor it returns Oculus HMD and runs as expected. It worked fine until recently when it just stopped building out properly.
Edi1t: I have now replicated this in the base VR template. I submitted a bug report as well.
Edite2: Bug report UE-70211 has been expected. Here is the link.
