What i have done now, is make one of those balls the default materials (with them all in the list thing), then i copyied the other balls (Drag/drop) onto the relevant materials in the defaults.
the only problem i have now is the Cromo and tire materials, they just wont copy, and, they dont appear as "balls", more of the texture the size of the box...duno what i have done there, but so far, its coming along good, just got to try and find AA in the render options..
