High lightmap resolution and still not the best quality


I’m trying to get the best quality possible in architect visualization, the wall static mesh is at 2048 lightmap resolution and a production light build but as you can see im still not getting the wall smooth color there is always something wrong, i have done the unwrap well, is it something with lighting?

outside are the sun and skylight
inside are spot lights

anybody can help what should i do ?

have you tried disabling “Compress lightmaps” on world settings? It’s known to cause these kind of issues.

thank you very much <3 , yes compress lightmaps did the trick
