Hi!
I have a question. How do I make a nrmal_maps from picture?
(i have a RGB picture with x=R g=y b=z)
or
(i have 3 grayscale picture picture x=pic1 y=pic2 z=pic3)
 like: http://www.blender3d.org/cms/Normal_Maps.491.0.html

I made i, but it is... :(

  normal {
    average
    normal_map {
        //[gradient x  ]
        //[gradient y ]
      [bump_map{jpeg "C:Normalsxnormal.jpg"} scale 5]
      [bump_map{jpeg "C:Normalsynormal.jpg"} scale 3]
      [bump_map{jpeg "C:Normalsznormal.jpg"} scale 3]
      //[gradient y, -1.0 scallop_wave scale 0.5]
      //[gradient z, -1.0 scallop_wave scale 0.5]

    }

  }
