Hi,
I have a problem im trying to get a texure on this texure map.

if created a png image to show what i want to see and what i dont want to
see.
on the bits i do show i want a some sort of rusty texure if created(far from
perfect yet)
but it only seems to show the red whit not a single bit of grey.
i know its not the texure itself because it does work on a normal box.
could anybody tell me what im doing wrong


//////this is the texure

#declare metal_roest =
      pigment {
        granite
        color_map {
         [0.0 rgb < 0.5, 0.5, 0.5> ]
         [0.4 rgb < 0.5, 0.5, 0.5> ]
         [1.0 rgb < 0.5, 0, 0> ]
        }
     frequency 1
        scale <30,10,30>
      }


//////and this the cylinder whit the image pattern and texure map

#declare huis_buitenkant_onder =
difference{
  cylinder { <0, 0,0>, <0,100,0>, 50 }
  cylinder { <0,-1,0>, <0,101,0>, 49.5 }
  no_shadow
  texture {
    image_pattern { png "mask.png" use_color interpolate 2 map_type 2 once}
    texture_map {
      [0 pigment { transmit 1 } ]
      [1  metal_roest]//color rgb < 100/255 , 100/255 , 100/255>}]
    }
    scale 100
  }
  rotate y*225
}

The "metal_roest" is being affected by the "scale 100" that applies to
the texture map, and you're seeing a tiny bit of that pattern that just
happens to be all red. Scale it back down by a factor of 100 and you'll
see the grey bits.

      [1 pigment {metal_roest scale 0.01} ]
