I’m interested in evaluating the daylight in the square room in the attached figure. There is an adjacent internal hallway. BSDFs are to be used on all four windows. From the tutorial by @sarith, I know how to evaluate the daylight if there is only one set of BSDFs, as if the exterior facade of the hallway was removed completely.
How would one go about simulating the daylight passing through the two sets of windows using BSDFs? If it is possible using multi-phase workflow with BSDFs?
