Uh, ok, but could you tell me precisely where to put the scale on a blob
object, because that example doesn't work fine :)


blob { threshold 0.1
 sphere { < 1001.000000 , 301.000000 , -1.000000 > , 50.100000 , 1.0
  texture { pigment { rgbft < 1.000000, 0.050000, 0.000000, 0.5, 0.1 > } }
finish { phong 1 } }
 sphere { < 1173.000000 , 101.000000 , -101.000000 > , 0.100000 , 1.0
  texture { pigment { rgbft < 0.990000, 0.000000, 1.000000, 0.5, 0.1 > } }
finish { phong 1 } }
 sphere { < 1173.000000 , 1.000000 , -1.000000 > , 49.900000 , 1.0
  texture { pigment { rgbft < 1.000000, 0.010000, 0.000000, 0.5, 0.1 > } }
finish { phong 1 } }
 sphere { < 1001.000000 , 101.000000 , -1.000000 > , 50.000000 , 1.0
  texture { pigment { rgbft < 1.000000, 0.060000, 0.000000, 0.5, 0.1 > } }
finish { phong 1 } }
 sphere { < 1345.000000 , 101.000000 , -1.000000 > , 49.800000 , 1.0
  texture { pigment { rgbft < 1.000000, 0.020000, 0.000000, 0.5, 0.1 > } }
finish { phong 1 } }
 sphere { < 1173.000000 , 401.000000 , -1.000000 > , 49.600000 , 1.0
  texture { pigment { rgbft < 1.000000, 0.040000, 0.000000, 0.5, 0.1 > } }
finish { phong 1 } }
 sphere { < 1345.000000 , 301.000000 , -1.000000 > , 49.700000 , 1.0
  texture { pigment { rgbft < 1.000000, 0.030000, 0.000000, 0.5, 0.1 > } }
finish { phong 1 } }
        scale 10
}
