Baked lighting shadow glitches, and black object

Development Rendering
1

I have 3 objects in this scene, the ceiling, the walls, and the floor. After baking the static lights, the ceiling if perfect, the walls have very buggy shadows, and the floor is just black. (Ray tracing and lumen is off.) Probably an issue with lightmaps, I’ve been at this forever please help.

Well I found 1 issue, the walls have a HORRIBLE UV map, but the floors UV map is perfectly fine.

I fixed my problems by just remaking the floor mesh and fixing wall UVs, but static lights just have SO many problems and bugs, I’ll have to do more research and probably make more posts
