Well, if you wait a little while (or a long while, still not entirely sure ) The next version of vray for sketchup is supposed to have proxy support. I am very curious to see what sorts of new goodies will be implemented next.

Did you have a red material in your model? I would say that you can never really trust an override render to give you a true idea of your lighting in your final because light will be bounced off of materials and change the tones in your image. For example, a red floor would give off a bunch of redish light (unless you override it in the materials GI).
