Strange Lighting issue when building light

Hey guys,

i got know errors after building the light.

your lightmap resolution is too low

i think there i another problem. i set the lighting quality to production and this is the result:

whats wrong?

Your lightmap resolution is still too low

And how can i change that or where are the options for this? And how should or could i set it?

This is such a basic question that I think you should read all the lighting documents: Lighting Tools and Plugins in Unreal Engine | Unreal Engine 5.3 Documentation

But to answer your question: Either in the static mesh viewer or in the actor properties.
