After stumbling upon Sketchfab I was intrigued by the fact that it states it has support for VR devices like the Oculus rift and Google Cardboard. Wanting to test these cool features out I redownloaded the necessary browsers to use this nifty feature and, I don't know how I am the first person to notice this, all functionality is broken due to Oculus releasing their latest SDK about 4 months ago.
Quoting from the Oculus dev site located here:
https://developer.oculus.com/downloads/pc/0.7.0.0-beta/Oculus_Runtime_for_Windows/
The most significant change is the addition of the Direct Driver Mode and the removal of Extended Mode.
This extended mode was required for these types of browsers to show their 3D content because you would have to actually drag the Sketchfab window onto the second "monitor" that was the Rift and then enable full screen mode.
To my knowledge there is no longer any way to enable extended display mode meaning there is now longer any way to view Sketchfab 3D models in VR.
I have tried searching this forum for others reporting the same problem but have found none.
If anyone has more information on this please speak up.
If it is in fact the case that you cannot view Sketchfab models on the Oculus rift headsets, this should either be mentioned on the main Sketchfab website or discussion that this website works with the Oculus rift should be removed.
