Twilight!

No, not teen werewolves and vampires but, the Twilight Render plugin for SketchUp.  It is a great value for only $100 and works pretty well as a direct plugin for SketchUp.  The interface is extremely easy to use and I was able to develop some quick renderings using the Paper Art Gallery SU model that I had created already.  The bump maps were a little buggy at times, especially while working within groups and components.   All of the images below were directly exported out of SketchUp, no post production.

The watermark is on all of the images because, I was testing the demo version.
