Perhaps he's using customGeom and not an object, so all changes are in the poser file? Perhaps something like:

material Materials Copyright 2002 Dodger Designs

    }

Leaving a 'blank' coloured material along with the others. I dunno, though, this one kind of bothers me in that Jaager's whole copyright-notice-on-a-material is bollocks. You can copyright a figure. You can copyright a morph target usually. You can copyright most textures (however, I'd argue that you CAN'T claim copyright on, say, an even halftone, basic stripe pattern, standard tartan, or a solid colour (I think it would be absurd for me to make a 1x1 pixel red GIF and claim that I then had control over the colour red). You can certainly copyright meshes. You can even copyright some poses, even though I think the buying, selling, and attempted protecting of poses is silly. But claiming a copyright on the settings of sixteen limited range parametres -- I really don't know about that. I mean, while you can certainly copyright the reflection map on chrome, I don't think it washes that you can copyright 'chrome'. Nor do I expect it would hold up on court much of anywhere.
