I have POV 3.1g. How do I make a metallic object look rusty and old? I
don't want the whole thing a rust color, I want patches of rust. 
Thank you.

  texture_map is the answer.

-- 
main(i,_){for(_?--i,main(i+2,"FhhQHFIJD|FQTITFN]zRFHhhTBFHhhTBFysdB"[i]
):5;i&&_>1;printf("%s",_-70?_&1?"[]":" ":(_=0,"\n")),_/=2);} /*- Warp -*/

What is wrong with color_map combined with pigment_map ?

An image_map would work as well but is considered cheating by the purists.

  You could also use material_map or even height fields with any of the
previously mentioned methods.

The benefit of texture_map is that you can vary the finish, too. No
need to explain why one would want that to model rust :)
