You are getting a primerib 3D model with garnish around it. The plate is extra and not included in the amount of polys displayed in the info. Texture maps in a Zip are; Diffuse, Bump, Alpha, and Spec. 512 and 1024. There is also the plate map, which is a light grey color.
When you are applying the maps. Make sure to click on the primerib first. The plate is a other object and needs its own material.
I have made it like this because the primerib could be placed on an other plate that the user has made. Or to be used without the plate...
If you have any questions or requests, please contact me right away.
The file is a .obj format. And will probably not be converted to any other format at this time.
