No, it should fade to black. As distance increases, it allows less and 
less light to pass through.

You are probably using too high of a color value or simply can't see the 
fading because of the pigment color. Make the pigment color "rgbf 1".

Skin is a different case, it scatters quite a bit of light. Interior 
attenuation can not simulate this, you need scattering media.
