Hi

Several people have asked for the grass texture in Mountain Valley, so here
it is.

#declare Base_Tex =
texture {
  pigment {
    granite
    turbulence 3
    color_map {
      [0.000 color rgb <0.5, 0.5, 0.2>]
      [0.25 color rgb <0.7, 1, 0.2>]
      [0.5 color rgb <1, 0.4, 0.2>]
      [0.75 color rgb <.5, 0.9, 0.2>]
      [1 color rgb <0.3, 0.9, 0.2>]
    }
    scale 0.035
  }
  finish{specular .25 }
          normal{
            average normal_map{
                [0.0 bumps 150 scale 30]
                [0.2 dents 50 scale 12.5 turbulence .3]
                [0.6 bump_map{ gif "GBM4.gif" bump_size 50} rotate x*90
rotate y*45 scale 30 ]
                [1.0 wrinkles 25 scale 5 scallop_wave rotate z*30]
                }//end of normal map
                rotate z*15 turbulence .4
              }//end of normal dec
}
