I am trying it out. I am really attracted to this becasue of all the pattern
options you already have. :) I will try to post a picture soon. My initial
feeling was that it would be great to have other texture options besides just
the rgb values.
I managed to accomplish this as follows:
In TBTFH.inc I changed:
//#local cylinder_txt = texture {pigment { rgb array_id_pgmnt[0] }
//                               finish {reflection 0.25 phong .6}}
#local cylinder_txt = texture {array_id_pgmnt[0]}

And in #macro PATCH_3 and #macro PATCH_3_wo_array I did this:

//         texture {
//                pigment {rgb array_id_pgmnt[array_pigment_id]}
//                finish {reflection 0.15
//                        phong 0
//                        diffuse .5
//                       }
//             }
           texture {array_id_pgmnt[array_pigment_id]}

Then I set my array, just to test:
// Pigment Array
#declare PArray = array[5]
#declare PArray[0] =
 texture {T_Gold_2C}
#declare PArray[1] =
 texture {T_Silver_3C}
#declare PArray[2] =
 texture {T_Copper_3C}
#declare PArray[3] =
 texture {T_Gold_3C}
#declare PArray[4] =
 texture {T_Gold_3C}

I can't figure out how big the array really needs to be. 3 might be enough?
