@dljrfn2003 It's strange because none of the testers reported the same problems you're having. All shaders have correct paths in version V1.0.2.1. Perhaps you have some conflicting mods.
Shader and texture paths will be fixed in the update.
The truck is nice, but I have a few reservations and suggestions. Add active instrument clusters (speedometer, tachometer, fuel gauge). Add active turn signals to the front, as they currently don't have any. Plug the holes in the bodywork that are visible when the doors are open (left and right), and the same goes for the wheel arches. After these steps, the mod will be completely fine.
