Strange, I tried an isosurface and the problem is the texture that is
showing. So I simplified the code to just a isosurface sphere and still
a problem. For example:

difference {
  anyObjectHere
   sphere { <0,0,0>, 1 }
}

works fine BUT

difference {
  anyObjectHere
    isosurface {
      function { x*x + y*y + z*z - 1 }
        max_gradient 4
        contained_by{box{-3.5,+3.5}}
      }
  }

leads to the area being "cut out" by the isosurface is very dark. Aren't
the above 2 spheres equivilant?
