Lines after building lights

Just built my lighting, and it all looks good but there’s these lines on the edge of each plane? I’m pretty sure it’s something to do with the Virtual Shadow Maps or something, but I’m just not really sure. Anyone help?

P.S> Yes I’m not on preview lighting settings its Production value quality, and the lighting has had time to load.

that is kinda “normal”. baked lighting doesn’t work too well with procedural world building. you’d have to explicitly model the rooms or use complete walls to have continous faces for consistent and continous lightmaps. that’s all about that.
