I have a sample VR project and I want to export it in HTML5.
I have HTC Vive headset and the VR preview works fine. I enabled the “Start in VR” flag under Project Settings, but when I package project and open it in Firefox Nightly it starts in plain 3D mode and not works on my headset.
What did I forget?
(Other HTML5 projects built with other frameworks (like A-Frame) work well.)
