In recent days I have a VR program which should be packaged for HTC Vive. I search the internet and cannot find way to solve it. When I real this Document https://docs.unrealengine.com/latest/INT/Platforms/VR/CheatSheet/index.html I found that I could use console command open and close VR render.
Only thing I should do is to add a Executed Console Command ] node in level blueprint and type “Stereo On” in it. It works.
I think someone maybe have problem when packaging VR program, maybe this post will help you.
