Question by Yellowyogurts · Oct 17, 2017 at 06:26 PM · meshprocedural meshuvsuv coordinatesuvmapping

UV V coordinate Not showing on Texture.

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

But what i get is this displayed on my mesh. https://imgur.com/a/4O6o6

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. https://imgur.com/a/bgC9B

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)
         );
