Hi guys, a bit confused with whats happening in my dialux, I tried to change the reflectance factors of walls, ceiling and floor higher than the default 70-50-20. I changed it by gong to construction > materials > change reflectance of room surface. Unfortunately, when I change the values of ceiling, wall and floor reflectances in one room, it applies automatically to other rooms as well. I do not intend to change the other room's default reflectance factor. What could be the reason?
