There are two parameters in global_settings:
global_settings {
    reflection_blur_max INTEGER
    reflection_blur_max_adc FLOAT
}

The reflection_blur_max keyword specifies a max trace level for 
blurring. The blurring will only be done below this level, after it is 
reached plain reflection will be used. This is similar to the 
max_trace_level keyword. The default value is the same as the default of 
max_trace_level, I think.

The reflection_blur_max_adc keyword specifies the ADC bailout for 
blurring. Blurring will only be done if the ADC weight is less than this 
value. This is similar to the adc_bailout keyword. The default should be 
1/255. There was a bug with this one, an integer instead of a float was 
used for it's variable, but it should be fixed in the latest versions of 
MegaPOV.
