WebVr development

Hello,

I'm trying to develop some vr visualization with hotspots to launch videos, display text and images in an Oculus like Krpano software.

I need to display it on the web, I tried with firefox, it works for 1 day and now when I try to use the helmet, I have no video, just the head mouvements work .

(win 10 x64 , firefox 72, aframe, babylon)

I tried to uninstall both firefox and oculus, I tried on a new windows install on another computer with windows seven, the same...

I think that's an update problem, but I can't resolve this issu.

So my questions : 

- Have you experienced the same thing, have you found a solution ?

- If you use webvr what is your development softwares.

- I want to learn to use unreal engine too but I need webvr display at this time, is it possible to display / convert a unreal engine project?

Thank you for your help
