Only absorbing media is used.

                           [0.4 rgb <1, 1, 0>*20]
                           [0.5 rgb <1, 1, 0>*40]
                           [0.6 rgb <1, 1, 0>*50]
                           [ 1  rgb <1, 1, 1>*90]
                        }
                }
              }

      }


Any suggestions or help will be appreciated.
