Its dead unofficially.

So I herd from a sketchfab vr support guy today. They are not going to continue to finish the steam app or fix any current issues? says it was just a demo and gave no other reason. that's is terrible news to hear since there webvr is buggy and crashes in firefox and chrome and unuseable. They should pass the app on and let somone with intrest and skill opensource and fork it , so it does not die, if its to complex for there develpers to finish or have no intrest.
