BTW, someone wiser than i did a tiny little tutorial somewhere about how the various specularity settings work. i'm fairly sure i got to it though brycetech.com... dang, my memory is failing me today. i think this is how it goes: The % specularity in the middle of the Mat editor says how much you want, and the specularity color up top spreads it around, from matte effect at black to a sharply shiny point at white. The halo color can give you an iridescence effect. Most cool: if white is very shiny and black is matte, you could use a greyscale texture (procedural or picture) to govern the shininess on a surface. Thus, shiny nose & chin & forehead, matte cheeks. i've been wanting to try that out, myself.
