Thank you! I also got it fixed before I saw the reply… I did:
old code
/newVertices.Add(new Vector3(x, y + 1, z + 1));
newVertices.Add(new Vector3(x + 1, y + 1, z + 1));
newVertices.Add(new Vector3(x, y + 1, z));
newVertices.Add(new Vector3(x + 1, y + 1, z));/
new code
newVertices.Add(new Vector3(x-0.001f, y + 1, z + 1.001f));
newVertices.Add(new Vector3(x + 1.001f, y + 1, z + 1.001f));
newVertices.Add(new Vector3(x-0.001f, y + 1, z-0.001f));
newVertices.Add(new Vector3(x + 1.001f, y + 1, z));
made the textures/vertices points overlap just a little
