Exvion has created an exporter to render Google SketchUp scenes with YafaRay. SketchUp is a 3D modeling program specially designed for architects, civil engineers, filmmakers, game developers, and related professions. It also includes features to facilitate the placement of models in Google Earth. It is designed to be easier to use than other 3D CAD programs.

Exvion's work consist of a special built of YafaRay and a plug-in script for SketchUp. For more information, take a look at this forum thread.
