I love how the physically-based model include an ambient map. Because you can't have those with Blinn-Phong shading.

Also, by physically-based rendering I assume they mean physically-plausible shaders.

Weird, but sketchfab demo is really slow here.

It seems broken right now. I think this was a special purpose demo. It did work back when it was released.
