Hi,
Inside the zip file you'll find all materials, textures, Skylight setup, cameras settings, Vray render settings, and 3D Skp. It is a fully textured with natural light setup, ready to render with Vray for Sketchup.
You can reuse the scene, the render settings, the lights, the materials, moving inside the project, observing how the light was created and handled, how materials are developed, what is the role that every textures play within them, and the values that fill every single option. If you want to use this file for commercial purposes, then do a few modifications especially the logos.
HAVE FUN AND ENJOY IT!
