The values in bold are then evaluated using the equations in the file perezlum.cal inside the RAYPATH directory in Radiance..

This data is then mapped to the "glow" material that represents the celestial hemisphere...You can edit the climate based sky produced by Honeybee and enter your own values. The other option would be to just use gendaylit from DOS Prompt.…
urs x 365 days ), and with modulus in the screenshot above, i could manage to do for every hour. but sometimes in my definition, i have a range from 1 to 35040, which is 365 x 24 x 4 ( 4 here defines every 15 minutes), on other word, when the number is one, then i have 01:00 O'Clock, when the number is 2 then i have 01:15 O'clock, when the number is 3 then i have 01:30 O'Clock...etc , so when the number is 97, which is the next day ( and after the number 96 which is equal 24 hours x 4), then I should have again 01:00 O'Clock.
I hope my idea is clear, thanks in advance!

me in 19 different pipeline components. Marginally better, but I'll still need to do this operation approx. 80 times...gulp.
Here's a wishlist request for David: expose string inputs in the Geometry Pipeline for Layer and Name. If I had that, I could change one string to swap my whole geometry set! (My layers have names like "B1 red rail", "B1 blue rail" etc., then the next time I'll want "B2 red rail", "B2 blue rail" etc.)
BTW, I'm happy to script something in C# if it will help: maybe I could write something like the Geometry Pipeline that takes a string input for layer name? Hmmm...

ide into 80 branches, and 80 outputs of explode and 80 dispatches - its my nightmare. Is there any way to do this with parametric Number of brunches? …
