did you render that in archicad?
i never rendered a final with archicad, i only use lightworks in archicad for previews, and it never looked that good
btw
i use artlantis 4,5 and now trying artlantis R 1,0 for final rendering (before retouching it with photoshop) but i really hate artlantis' editing interface...so not efficient... but it did good renderings and most archicad friendly
i guess this is out of the topic...hehehehe
