[Radiance-general] mkillum settings - borrowed light

[Lars O. Grobe]

Hi!

hm, genrad, not part of the radiance distribution? Is it genrad from 
that old CAD-integration project?

Just add a line at the beginning of the window's scene description:

#@mkillum s=16 d=8

As for specifying different av settings for the windows, I guess things 
will get really complicated when you want to automate the mkillum 
processes. You can specify the mkillum settings in the input file, but 
what you want to set (av, ar, ...) are the rtrace parameters that 
mkillums uses when starting rtrace processes.

Do you really need different av's? I'd increase the overall ambient 
accuracy, set a high ab (not needed for the outer windows, but it is not 
so important in rendering times if only used for the illum generation).

Good luck! Lars.
