Uneven Lighting across surfaces

I am getting uneven lighting across a surface. It’s several static meshes that are all perfectly aligned with each other and they all have the same material. Any idea why I’m getting such harsh lines and differences in lighting here?

I figured it out, in case anyone else runs into this. Doing a lighting build at a higher quality fixed the problem… Or at least made it very much less pronounced

Try tweaking the volumetric lightmap (in World Settings) or in a post process volume to get a more accurate result, and get rid of the lines / splotches. There’s also enabling two-sided distance field generation and/or increasing the distance field quality (resolution) in the mesh editor settings for each mesh.
