Ready to render with eevee: all the parts are shaded and textured
Materials and textures are packed into blend files.
You can change livery color from node editor or load your custom texture to the base color node in Principal BFDS material.
This is not a technical vehicle model, all components are designed and modeled inspired to the real but is a concept.
