Normal map causing lighting errors and pixelated lines at further distances or shallower angles.

Question

I am trying to make a really good looking game, but I am having some trouble. I found a cool asset that I would like to use (https://assetstore.unity.com/packages/3d/environments/sci-fi/sci-fi-construction-kit-modular-159280). When I load into the example scene I see weird pixelated lines from the normal texture of the floors farther away from me. I don't know if it is because it is farther away or it is a shallower angle from the camera. My Quality is on ultra, I have tried setting all textures to no compression and a $$anonymous$$gh max size but t$$anonymous$$s doesn't seem to work. When I take off the normal texture from the floors the issue goes away. The normal texture does add some nice detail so I would like to keep it alt text Is there some setting I missed or does it just need $$anonymous$$gher quality textures? If anyone could help I would greatly appreciate it.

After a lot of searc$$anonymous$$ng I came across the mipmap bias value for the texture import settings. It is a $$anonymous$$dden value for some reason so I had to figure out how to set it in code. Here is the code if anyone has t$$anonymous$$s problem in the future.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEditor;
 using UnityEngine;
 
 [CustomEditor(typeof(TextureImporter))]
 public class OverrideImportSettings : Editor
 {
 
     float hSbarValue = 0;
     float prevvalue = 0;
     public override void OnInspectorGUI()
     {
         base.OnInspectorGUI();
         hSbarValue = GUILayout.HorizontalScrollbar(hSbarValue, 1.0f, -1.0f, 1.0f);
         if (prevvalue != hSbarValue)
         {
             prevvalue = hSbarValue;
 
             TextureImporter importer = (TextureImporter)TextureImporter.GetAtPath(Asset Path);
 
             importer.isReadable = true;
             importer.textureType = TextureImporterType.NormalMap;
             
 
             TextureImporterSettings importerSettings = new TextureImporterSettings();
             importer.ReadTextureSettings(importerSettings);
             importerSettings.mipmapBias = hSbarValue;
             importer.SetTextureSettings(importerSettings);
 
             EditorUtility.SetDirty(importer);
             importer.SaveAndReimport();
         }
     }
 }
