Hi,
I’m quite new to Radiance and for the past couple of days I’ve been having some problems using BSDF’s.
Just to try it out, I tried to compute a BSDF from a glass polygon using genBSDF which gave me a .xml file. Then I tried to define another material with the BSDF modifier using the .xml file as an argument. However, rendering the same picture, one with the original glass polygon and another with the BSDF-glass polygon, produces quite different outcomes. My question now is: Should the rendering outputs be different, and if so, why? Or should they be the same, and if so, is there something obvious I’m missing?
Thankful for help,
Isak
