Will combining multiple meshes improve lightmapping speed / map layout?

Got a bunch of walls made out of a dozen prefabs / kitbashed together.
If I combine those with something like Mesh.CombineMeshes, will it improve lightmapping speed / quality?

Probably, yes - I’ve found that I get better performance and more correct lighting on my interiors after combining objects. However depending on your project setup, you’ll need to consider the best way to combine, for things like Pixel Light Count and how many lights shining on a single mesh etc.
