Howdy,

See the attached ..... given these settings I was hoping to get some 
help/advice on the results of a radiosity run ....

#if (UseRad)
  radiosity {
    pretrace_start 0.08
    pretrace_end   0.005
    count 200
    nearest_count 8
    error_bound 0.7
    recursion_limit 1
    low_error_factor 0.4
    gray_threshold 0.4
    minimum_reuse 0.0075
    brightness 2.8
    normal on
    always_sample off
    adc_bailout 0.01/2
    }
  ambient_light 0
  #end

I've scaled my stucco texture in some places ..... wall with hurricane lamps 
and the inside of the archways and I'm mostly satisified, however I 
concerned about the appearance of the surface normals on the towers to the 
left and right of the central tower. Question .... will I be able to smooth 
those out with aa? This run I used +am1 +a0.03 +r3 ..... currently it takes 
just under two hours, so I'm anxious to resolve the mentioned problem before 
I commit to a "beauty" run .... +am2 +a0.1 +r2???? Oh yeah .... I'm leaning 
towards changing the light source in the close up alcove ..... I'm not 100% 
happy with that.

Thanks Jim

I think you're nitpicking, Jim.  The scene looks great.  Your radiosity 
settings and the normals on the two columns are fine as well.  Go for 
the final render.
