Hi, according to a 2013 sketchfab blog post 3D Space Navigator support was added to the model viewer when using Chrome browser. See http://blog.sketchfab.com/post/45491180114/spacenavigator-integration
I can’t get this to work with Chrome on Mac or Windows, did the GamePad API + SpaceNav support get dropped at some point? It’d be really great to get it back!
I also tried Chrome + Sketchfab with an Xbox gamepad controller as well and the model viewer doesn’t respond.
The Gamepad API + SpaceNav is working okay for when I try http://html5gamepad.com/
