So I am currently trying to display this texture for test purposes.

But what i get is this displayed on my mesh.

If i read it correctly my V value does not change.

However when i move move mesh up from 0-1 on the y axis the mesh color changes from red to green.

So ofc my V value is based on the y coordinate. This is i do not understand since i i never use the y axis in my code i only use the X and Z axis.

public static Vector2 vector3ToUV(Vector3 vector3) {
    return new Vector2(
        ((vector3.x + ((XGridSize / 2) + 0.35f)) / XGridSize),
        ((vector3.z + (ZGridSize / 2) +  0.35f)) / ZGridSize);
}
    Vector3 v1 = center + NodeMetrics.GetSWCorner();
    Vector3 v2 = center + NodeMetrics.GetNWCorner();
    Vector3 v3 = center + NodeMetrics.GetSECorner();
    Vector3 v4 = center + NodeMetrics.GetNECorner();

    AddQuadUV(uvs,
        NodeMetrics.vector3ToUV(v1),
        NodeMetrics.vector3ToUV(v2),
        NodeMetrics.vector3ToUV(v3),
        NodeMetrics.vector3ToUV(v4)
        );

MY shader was the problem i based uv coordinates on the world position of the object. code worked.
