How can I make my texure line up right with the default cube

Question

So I have a square texture (300 X 300) and I would assume that it would align right with the default cube all around but on some faces it flips the image upside down.

On three of the four faces the texture is fine and is the right side up but it flips it on one side and I can't figure out why.

I added a T to the top of the texture to help illustrate whats wrong. Any help would be great. alt text

 using UnityEngine;
 
 public class FILENAME : MonoBehaviour {
 
     //Flips the UV on the backside of the cube so it matches the front and sides
     void OnValidate () {
         Vector2[] uvs = GetComponent<MeshFilter> ().sharedMesh.uv;
 
         uvs [6] = new Vector2 (0, 0);
         uvs [7] = new Vector2 (1, 0);
         uvs [10] = new Vector2 (0, 1);
         uvs [11] = new Vector2 (1, 1);
 
         GetComponent<MeshFilter> ().sharedMesh.uv = uvs;
     }
 }

Was struggling with the same (I'm an absolute beginner) and this solved it immediately.

Some additional questions.

How often is the OnValidate() executed ? Only in Editor, and only after change of GameObject?

Does the script need to remain attached to the cube or prefab once it has executed? (I expect it to have updated the uvs of the cube (in the prefab) and does not need to remain attached).

Thanks.

     // you are correct, here's another example
 
     // first script
      using UnityEngine;
      
      public class MyGameObjectClass : MonoBehavior {
      
          public GameObject cuber;
     
          void Start () {
              MyStaticClass.FlipCubeFace(cuber);
          }
      }
     
     //second script
      using UnityEngine;
      
      public static class MyStaticClass {
      
          public static void FlipCubeFace (GameObject cubee) {
              Vector2[] uvs = cubee.GetComponent<MeshFilter> ().sharedMesh.uv;
      
              uvs [6] = new Vector2 (0, 0);
              uvs [7] = new Vector2 (1, 0);
              uvs [10] = new Vector2 (0, 1);
              uvs [11] = new Vector2 (1, 1);
      
              cubee.GetComponent<MeshFilter> ().sharedMesh.uv = uvs;
          }
      }
