I want my pigment used as a function for an isosurface to correspond 
with a pigment used as a texture. Here is the code. It's simple, I want
red groove :

light_source { <1,1,2>*10000 color rgb 1.4 parallel }

camera
{
   location <2.5,1.7,9.5>
   look_at <0,1.7,8>
}

#declare F_PilierEntree =
function
{
   pigment
   {
     crackle
     color_map
     {
       #local cc = 0.1;
       [ cc-0.05 color rgb 0 ]
       [ cc color rgb 1 ]
     }
     scale 0.1
   }
}

#declare T_PilierEntree =
texture
{
   pigment
   {
     function { F_PilierEntree(x,y,z).gray }
     pigment_map
     {
       #local cc = 0.001;
       [ cc color red 1 ]
       [ cc color rgb 1 ]
     }
   }
}

isosurface
{
   #local R = 0.15;
   function { x*x + z*z - R*R - 0.002*F_PilierEntree(x,y,z).gray}
   max_gradient 2.5
   contained_by { box { <-1,0,-1>, <1,2.4,1> } }
   translate <0,0,8>
   texture { T_PilierEntree }
}

Thanks

gRRominet has found on irc : the translate must be under the texture.
