This medieval merchant house is based on a real, still-standing medieval house (and its even open to visitors!) that was built in around the year 1300 in Southampton, England. The lighting is completely dynamic with distance fields being used. The lighting in the cellar/undercroft was messed up due to DFAO artifacts caused by a bug that occurs under landscapes which I believe is due to be fixed in Unreal Engine version 4.22. I also had some light leakage in the ceiling which I haven’t fixed yet.
