Lighting Issues with custom generated mesh

I think i did, since half the wall is working as intended. I did mesh.recalculateNormals().

 public void Generate$$anonymous$$esh(int [,] map, float squareSize) {
             outlines.Clear();
             checkedVerticies.Clear();
             triangleDictionary.Clear();
     
             vertices = new List<Vector3>();
             triangles = new List<int>();
     
             squareGrid = new SquareGrid(map, squareSize);
     
             for (int x = 0; x < squareGrid.squares.GetLength(0); x++) {
                 for (int y = 0; y < squareGrid.squares.GetLength(1); y++) {
                     TriangualateSquare(squareGrid.squares[x, y]);
                 }
             }
     
             $$anonymous$$esh mesh = new $$anonymous$$esh();
             cave.mesh = mesh;
     
             mesh.vertices = vertices.ToArray();
             mesh.triangles = triangles.ToArray();
     
             int tileAmount = 10;
             Vector2[] uvs = new Vector2[vertices.Count];
             for(int i = 0; i<vertices.Count; i++) {
                 float percentX = $$anonymous$$athf.InverseLerp(-map.GetLength(0) / 2 * squareSize,map.GetLength(0)/2*squareSize , vertices[i].x) * tileAmount;
                 float percentY = $$anonymous$$athf.InverseLerp(-map.GetLength(0) / 2 * squareSize,map.GetLength(0)/2*squareSize , vertices[i].z) * tileAmount;
                 uvs[i] = new Vector2(percentX, percentY);
             }
             mesh.uv = uvs;
     
             if (!is2D) {
                 CreateWall$$anonymous$$esh();
             }
             mesh.RecalculateNormals();
         }
