The volume input is for volume scattering and attenuation - i.e. the alteration of light rays as they pass through a colored medium, like oil, colored glass, or coffee, or a liquid or gas with particles suspended in it like smoke, fog, etc. The latter is a phenomenon that includes scattering but not from "solid" things.

Someone should tell the Poser engineers that Poser is allowing something that can't be done. Sorry Ted, I checked before I posted that image. As you can see in the screen image, the volume connection is NOT greyed out, and I had just disconnected that input to show that Poser would allow it.
