Bug with 360 lookaround camera

I have forked officials’ project,I have not make any changes with this project,then I run the project,it become like this.

Here is my fork project Link.

That project was down before Chrome introduced that policy. It basically means you can’t auto play videos unless you mute them or you can only play them when the user interacts with the page (eg clicks)

Oh,thx,I already found my problem:)My material’s Cull mode should be transform to “Front Faces”.
