Im new to radinace and I want to calculate the BSDF of a CFS. I wonder if the surface normal of the glazing system is important to genBSDF ? also i use BSDF as the material for the slats which also has an up direction, and i wonder if this also important to genbsdf? also after creating the slats and glazing how can i be sure my orientation is correct ?
when i created the bsdf of the whole CFS, the bsdf viewer does not show any data at end (probably there is an error but i have no idea where did i go wrong coz it works for other correct BSDF files), I would appreciate your help in this too or a bit of your invaluable experience.
