Get rid of unever lighting between sections of a landscape

So I have a level that has the landscape used as a floor, that the player can walk around. The problem is that the shadow on the floor is not working as it should be and is giving me straight lines. Lines like these.

Does anyone know a fix to this? I read somewhere that turning off “static shadows” fixes this but it doesn’t. If I do anything to the landscape and the lighting is unbuilt it looks how it should in the editor, but then i build the lighting and it looks wrong again.

Thanks.

It’s as if the game collects the total amount of light/shadow and then just universaly applies one specific amount of shade to a specific quad. Anyone know how to adjust this maybe?
