Must be so.  So... direct from the documentation (really helpful to use that, the
documentation):

#include "colors.inc"
#include "textures.inc"

plane {z,0
   texture {
      material_map {
         png "povmap.png"
         texture {  //used with index 0
            pigment {color red 0.3 green 0.1 blue 1}
            normal  {ripples 0.85 frequency 10 }
            finish  {specular 0.75}
            scale 5
         }
         texture {  //used with index 1
            pigment {White}
            finish {ambient 0 diffuse 0 reflection 0.9 specular 0.75}
         }
         // used with index 2
         texture {pigment{NeonPink} finish{Luminous}}
         texture {  //used with index 3
            pigment {
               gradient y
               color_map {
                  [0.00 rgb < 1 , 0 , 0>]
                  [0.33 rgb < 0 , 0 , 1>]
                  [0.66 rgb < 0 , 1 , 0>]
                  [1.00 rgb < 1 , 0 , 0>]
               }
            }
            finish{specular 0.75}
            scale 8
         }
      }
      translate -.5
      scale 15
   }
}

light_source {<10,10,-10>,1}
camera {location -10*z look_at 0}

As you can see it's unlike the other mappings, such as image_map, in that there isn't
a "blend map"
index.  It can only be integers 0 through 255 so no decimals could be used anyway.  I
suggest the
doc be read about it.  Right-clicking on the keyword in the CodeMax Editor (Windows
platform is all
I know) will bring up the Context Help where you can read about it.
There have been problems with some BMP files (btw, use sys as the file type) so if you
get faulty
renders once everything else is right then converting to another (paletted preferably)
format to
use instead should fix things.
