I expect to see a glowing white ball on a blue plane.  Any help appreciated :)

#version 3.7;
#include "colors.inc"

camera { location <10,10,-2> look_at <0,4,0> }

#default{ finish{ ambient 0 diffuse 1 }}

global_settings {
    radiosity {
      pretrace_start 0.08           // start pretrace at this size
      pretrace_end   0.04           // end pretrace at this size
      count 35                      // higher -> higher quality (1..1600) [35]
      nearest_count 5               // higher -> higher quality (1..10) [5]
      error_bound 1.8               // higher -> smoother, less accurate [1.8]
      recursion_limit 3             // how much interreflections are calculated
(1..5+) [3]
      low_error_factor .5           // reduce error_bound during last pretrace
step

      adc_bailout 0.01/2
    }
}

sphere { <0,0,0>,1 texture { pigment { White } finish { ambient 10 } }  }

plane   {
        <0,-1,0>, 0
        texture { pigment { Blue } finish { ambient 0 diffuse .6 } }
        }

IIRC, in 3.7, it's emission, not any more ambient.
