    I was making a tessellation study using cylindrical UV mapping projection as research in Unity.
    Notice the zigzag issue


    I notice that in the mesh there was some UV stretching.


    It was not a problem about UV mapping projection stretching. So I increase mesh polycount density by adding some extra loops so that the mesh has more square quad shapes instead of stretched squares. And that works!


    IN CONCLUSION, minor quads stretching create tessellation zigzag issues (not UV mapping stretching)
