The trick is to use sketchup's built in fog. You can use it as a z-depht image of the model. With the z-depht information you can add a fog effect or use it to make things out of focus with the lens blur filter in photoshop. As for the light streaks- those are just blurred lines.

Im a noob and need some step-by-step tutorial to do this trick. Any1 knows one please?
