I downloaded the beta for the VRay rendering plugin for SketchUp. Below you will see the result of just loading and a one-click render.
I haven't had a chance to fiddle with materials at all, and the shadows are from SketchUp's shadow configuration. Rendering was pretty quick, but this is a simple scene of one of my printers. The blob on the top left is the beta version watermark.
VRay is a high-end renderer, and this is good news for SketchUp fans. There are definitely some competing renderers that are used heavily by the SketchUp community, but it's a good sign that SketchUp is taken seriously enough for a renderer of this caliber.
