Hi! Actually I've just started to use Luxrender recently this is one of my first renders with it. I usually use V-ray or cinema4d's internal renderer, but this stuff is great!! This is a fast sketch of the facade of Walter Gropius's Bauhaus building. I know the Depth of field is a bit too much (small modell size and 1.8 F-stop) , I'm just experimenting.
The model was built in Cinema4d R12 and I used LuxC4D to export it.
