Lightmap artifacts and normal maps

Hi, Unreal newbie here. I’m having issues with lightmap artifacts even thou the normal maps look perfect on my models.

  • I have Use Normal Maps for Static Lighting checked.

  • Lightmap compression is turned off

  • Changing the Overridden Light Map Res does very little. I tend to set it to 256 or 512.

-Here are my World Settings/ Lightmass settings.

Nmap Only (Looks Good):

Base Mesh only:

Below are some examples for a simple cube. Some edges are made hard while others are soft to avoid Normal map artifacting.

Lightmap with normal map (Unexplained Blotches on different sides):

Any help would be nice as I’ve been spending hours trying to wrap my head around Lightmass and it limitations.

I could also upload the meshes and their normal maps too since they are personal works of mine.

Thanks for you time.
