Ooof! Something really weird happens when I run:
gensky 6 21 10:30 -g -c
Not sure what it does, but it includes a sun.
Time to rerun some simulations...

Huh? You get the default value if you *don't* specify a -g option. If
you use -g 0.30, you would get a ground reflectance of 30% instead of
the default 20%.
Make sense?

So is the default never used? Or only when -g is not given?
On 2011-02-07 13:49:44 -0800, Gregory J. Ward said:
That's because -g is expecting an argument (the ground reflectance).
If you give "-c" after, it probably calls atof("-c") which returns 0.
In general, Radiance doesn't have very paranoid argument checking. If
you don't give a legal command line, many Radiance programs just muddle
through (or crash if they try reading past the last argument). The
exceptions to this are the rendering programs and a few utilities that
call badarg() to check command argument types.

If -g is given as the last argument to the gensky command, a bus error
or segmentation fault results. That is:
gensky 3 31 10:00 -g -c
works, but
gensky 3 31 10:00 -c -g
fails.
