Reflectance in Radiance

[KasperS]

Hello

I have been sitting and trying to figure out how the reflectances work in radiance, because i can't seem to get them to work.

If i perform a DF calculation of a normal room 5x5x3 m room with 40 % glass, i have tried to set all the reflectances to both black (0 % reflectance) and white (100 % reflectance), but they still give the same results. In the color map i have changed the materials there to the different colors.

If i just use the materials already created, it works, and the results seems a lot more reasonable, but i cannot use the "colorthing" where i choose my own colors.
