Lighting problem

Hello, I have made a room in the editor with 2 point lights and when I build lighting this happens on walls and floors. Anyone knows how to fix that?

it’s either that or the normals aren’t perfectly aligned.

This particular issue is covered in detail here.

i was more referring to model normals as it doesn’t look like you’re using a normal map.

This happens with Materials that come with Starter content, so I doubt it’s the normals that are causing he problem. And on that page is my problem but it’s not fixing it.

It is Starter content model aswell and I’m preety sure they use NM
