Hmmm… It might turn out to be a brave browser problem… If so I am terribly sorry!!
But, to my defense, the brave shield is down when I test both URLs. 3D stuff or even virtual tours (photography) do not work with the shield up. So I turn it off anytime I want to look at 3D or virtual tours.
Just tested in Chrome and both links work for me as well there.
I’m very glad it is working now. Those two domains are forwarded to the same source, so they should always be the same. If they are not we have to check why.
BTW, at this point, a great thank you to all the people chiming in, the tone and manner in which responses come across and the great effort the admins and developer put into BabylonJS so guys like me, 3D artists coding level, can make use of this and present our 3D content on the web. Interactive, sexy and painless (to a certain degree).
