I modeled the stained glass window to a point that I’m happy with. I experimented with different saturations and values, but this was the most accurate representation of real stained glass I could get. I attempted to texture it in Substance Painter, but there’s a very bad bug for Mac OS that causes the program to crash a lot so I’ll have to come back to it later when they fix it.
Until then, a basic bump map for the metal parts and rippled lead glass. I also added a metal trim design to integrate the dark fixture into the white ceiling. The ceiling will be textured later with some kind of stone/marble/granite. There are just a few tall cubes above the fixture to test out transparency so the final look with the real building will change.
