As Thomas wrote, rtrace does not care about this. You can use a RIF-file 
when you pass its name to rad as a command line argument, e.g.

bash#rad myRenderings.rif

Now rad would read in the setting, and call the commands necessary to do 
all calculations as defined in the RIF-file.

If you call rtrace, the rtrace-options apply. rtrace does not know 
anything about the existance of you RIF-file. The file name of the 
RIF-file does not appear on the command line you posted - how should 
rtrace know to use it?

How did you arrive at the ambient parameters you are using? Especially 
ar 32 combined with very high ad amd as? Did you consider scene size and 
level of detail / irradiance variance?

Cheers Lars.
