Yes, with LightUp you can "bake" shading effects on your materials and export those in certain formats. There is a fully working, 30-day trial of it - give it a "trial" (Sorry for the terrible pun but I could not resist )

Hi B uttlamo, With su 6, you can always go to Google's official site and download the pro version: http://sketchup.google.com/support/bin/answer.py?hl=en&answer=60107 If you don't have a license for it, it will gracefully downgrade to the functionalities of the free version and from then on function like free after the 8 hours of trial working time.
