1. You can't layer just the pigments, you can only layer complete
textures.

2. When you layer textures, the last one needs to have some sort of
transparency (filter or transmit) otherwise you can't see through it to
the underlying layer.


 height_field {jpeg "mount.jpg" smooth
   texture {pigment {image_map{jpeg "mount_green.jpg"}}}
   texture {
     pigment {image_map{jpeg "road.jpg" transmit all 0.75}}
     finish  {ambient 0.1 diffuse 0.9 phong 0.5}
   }
 }
