> thank you for your reply! How can I change the contents of the channels?
You do not have to "change" them, you must enter the values for any
simulation anyway. Define three channels you need, and enter them just
as you would do with red green and blue values in their corresponding
fields when defining reflection, transmission and emission of your
surfaces. Of course you must know the properties of you sources and
surface materials for these channels. The point is that in your mind,
you have to replace the meaning of the RGB-values, usually taken as
RedGreenBlue, with Channel1Channel2Channel3. Colors are just "channels"
of radiance in this meaning, so just change the wavelength and you can
use it for anything ;-)
Of course as Greg already wrote you should consider if the effects of
radiance that are modeled in Radiance are enough or if you need other
energy transports for your work, too.
CU Lars.
