the outside), but I can only do in a disc object with the following code

disc{ <0,0,0>, <0,1,0>, 1.0
      material{
      texture {
                    spherical
                   texture_map {
                                         [0.0  pigment{rgbft <1, 1, 1, 1 ,
0>} finish{ambient 0 diffuse 0}]
                                         [0.4  pigment{rgbft <1, 1, 1, 0.4 ,
0>} finish{ambient 0.5 diffuse 0.7}]
                                         [1.0  pigment{rgbft <1, 1, 1, 0 ,
0>} finish{ambient 0.5 diffuse 0.7}]
                                        }
                 }
                 }
       scale <60,60,90>
      translate 100*z
     }

When applying to a sphere the render goes black.

Any ideas?
