For one thing, as far as I know, connecting the texture into Specular_Color whilst set to 'absolute' black (i.e.: 0/0/0) will have no effect whatsoever. Absolute black in the specular color channel is equivalent to 'OFF'. The contrast may be a result of using a color map as a bump map. Certainly looks that way in the material surface view.

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
