so I’m making an archviz project of a whole house, with regular sized windows (not those enormous glass panels that every archviz tutorial has) and just sun and sky lights, so you can imagine that the rooms that don’t get direct sun light are having a bad time dealing with lightmass. I never managed to get useable light maps even for the well lit rooms until now, had to manually unwrap everything, manually set map sizes, but after I spent a lot of time messing around with lightmass and watching videos, I finally got decent results for my this bad lit scene.
except for the walls. there’s this noticeable banding:
I mean it’s clearly pixelated, but if you notice the sun light is not nearly as pixelated as thesse big clear rough edged squares abd this color banding on the walls. and even though I packed many walls together in the same uv map, their resolution is 2048px. so it really shouldn’t be a problem with resolution?
what could it be?
ps.: this was baked in production quality, with some lightmass settings overrides, such as 1.1 for static lighting level scale, 5 num indirect lighting bounces, 2 num sky lighting bounces, 1.1 indirect lighting qualityt, and 1.2 indirect lighting smoothness. swarm says it took 1,32e+04s to render and I have no idea if it’s 13200, 1320 or how many seconds but I’m assuming it took a long time, since I left it baking overnight.
