This scene is around 30,000 polygons, and is ready to render. What you see in the images is what you will get if you render it with no changes. It's set up with global illumination, and very high resolution textures, and makes a good backdrop for alley scenes. The fire escape is 20,500 polygons, and includes nuts and bolts, the wall and windows are less than 2000. The textures are all hi resolution, and many of them are perfect tiling textures. The graffiti is in separate texture channels and can be removed easily simply by deleting the channel in the material. No plugins are required for this scene to work perfectly. It works in both the default scanline renderer, and also in the Mental Ray renderer, as well as several others I have tried.
