Hello, this is what I recently did in Sketchup 7.1 and with Kerkythea renderer. Later a little softening of edges in Corel Photo Paint. I'm not sure if it will get better if I would insert textures... but I'll try it later. Thanks for watching...

TIG,

I am quiet new to sketchup and to this site. But your plugin makes the difference. It's to me the only thing one could miss in sketchup compared to 3d max... So, thousand thanks again ...
