Thank you :)

It's a couple of macros that build layered textures using a grayscale image map
pigment function as an image pattern to give variable reflection based on map
color. This serves as the bump map and underlying pigment layer too, but with
other grungy stuff averaged on top, something like:

#macro T_Ship1(vecScale, useUV)
   function { fn_P_Hull(x,y,z).gray }
   texture_map {
      [0
         #if (useUV) uv_mapping #end
         pigment {
            average
            pigment_map {
                [2 rgb 1]
                [2 P_Metal01]
                [2 P_Metal02]
                [4 P_Hull]
            }
         }
         normal { N_Hull }
         finish { diffuse 0.65 }
         scale vecScale
      ]
      [1
         #if (useUV) uv_mapping #end
         pigment{
            average
            pigment_map{
                [2 rgb 1]
                [2 P_Metal01]
                [2 P_Metal02]
                [4 P_Hull]
            }
         }
         normal { N_Hull }
         finish {
            diffuse 0.85
            reflection { 0.1, 0.5 fresnel on }
            conserve_energy
         }
         scale vecScale
      ]
   }
#end

object { shipPart texture { T_Ship1(15, true) } interior { ior 2 } }


The main greebles image map is just a bunch of random rectangles of different
size, scales, and shades of gray from almost white through almost black.
