Setting “Min Lightmap Resolution” is for creating a second UV set inside of Unreal and only determines how much spacing there will be between the generated UV shells.
“Lightmap Resolution” is the actual resolution that the lightmap will be created at.
By checking “Override Lightmap Resolution”, you are telling Unreal to ignore the 1024 lightmap and instead build a very small 128 map.
By making a small lightmap and putting it onto UV shells that are spaced too tightly together, you are getting a large amount of shadow bleeding and errors.

You just need patience to build at Production quality. Leave it on overnight or something, because no one is going to build it for you

Thanks for you answer. I will unchecking “Override Lightmap Resolution”
