The ones I posted aren't drawn over, it's the shaders (post-pro, you could say).
The guy posted the node-structure on... polycount (I think), it was intense stuff.

Holy shhhhhhhhhhhit! Love it but I love more the stairs Also like a lot the thing (don't know how to say it in English) around the stairs (the glass one) but it is confusing.

Railing is the word you're looking to find.

Also I dislike the stairs. they look dis proportional. The ways the reflection happens.
Puts me off.

Thanks for the word xD

Yeah, they really look a bit unfitting. still, the sheer quality of the render itself is nice.

Hahahaha that's fucking incredible I wonder how long It took to render.
Oh also software?

peaches!

they look very realistic.
