Line Renderer Stretching and compressing weirdly

I have a script that controls the positions of the line renderer. I want it to display this conveyor belt texture (below). It seems to tile the last row of the texture instead of tiling the whole thing.


I set up the material like this (below).


Am I doing something wrong? It would just either stretch the texture or tile the texture weirdly if I change the texture mode.

Code (CSharp):

1.  
2.     Vector3[] GenerateConnection() //Generate a connection for two gameObjects. This method rests on a "Connection" class.
3.     {
4.         startPos = start.position;
5.         endPos = end.position;
6.  
7.         Vector3[] connection = new Vector3[4]; // connection stores the Vector3s that are in the line.
8.         connection[0] = startPos; //starting position of the "connection"
9.         connection[3] = endPos; //ending position of the "connection"
10.         connection[1] = new Vector3(Mathf.Lerp(startPos.x, endPos.x, 0.5f), startPos.y, Mathf.Lerp(startPos.z, endPos.z, 0.5f));
11.         connection[2] = new Vector3(Mathf.Lerp(startPos.x, endPos.x, 0.5f), endPos.y, Mathf.Lerp(startPos.z, endPos.z, 0.5f));
12.  
13.         line.SetPositions(connection);
14.  
15.         line.material.SetTextureScale("_MainTex", new Vector2(DistanceVector3Array(connection), 1));
16.  
17.         return connection;
18.     }
19.  
20.  

 

Texture "wrap mode" set to "repeat"?
