This is a high-quality bookshelf. Buying this will give you two copies. One with the materials and light, and one without any materials or lights. This way, you are free to customize the model however you please. The model was rendered using mental ray, however it is not restricted to mental ray, since there is freedom with the materials. the materials are all made in the program, therefore, there is no need for finding or matching textures. Just open the file and you're ready to go.
