The Graphics resource is the central part of vehicle graphics bundles, superseded only by the GraphicsStub resource in the event a GraphicsStub exists. Its primary purpose is to import Model resources and set them up as vehicle parts.

Although the version number remains 3 in all known variants of the resource, it was updated at least once between February and October 2007.
