[Radiance-general] gensky sky type

[Jia Hu]

Dear Wendelin,

I find that the weather data is -L 0 0, which causes the error message. It
is a false alarm. I may simply ignore this error message. I am using
gendaylit 2.0 downloaded from your website. Glad to know there is a new
release!

gendaylit 1 1 8 -a 25 -o 75 -m 75 -L 0 0

Thanks,
