That's actually pretty decent!! However, the template is different, so you have to adapt to it. What I mean is, that you cannot do the sides of a truck skin the same way as on a NASCAR skin, because the cockpit and bed of the truck template are not connected. Other than that, great first try!!!
That probably means an error in the materials.cs file. You probably should go through the file and check the names in the file.
