Render Problem

Hey, I’m having a problem with lines across my game scene,Ive noticed this sometimes happens on terrain also.I’ve tried a few different light set-ups and cant get rid of them.Does anyone know how this could be fixed?

Is that a shot from editor or game window? I get this kind of banding in the editor view all the time but not in actual game view.

this is in the actual game.Might have solved the problem,re-imported models as .fbx and scaled all the models down in unity.not sure what fixed it but seems to have stopped. I’ve had it before on large terrains so maybe it comes from scale issues
