I have the horizontal lines going in the right direction, but they don’t follow the direction of the hat. I have also tried connecting the UV to Vector but still can’t get it to work. Any ideas? Thanks.
That’s what I got with your settings. I see the UVs are different though. What am I doing different?
Blender will stuggle to straighten an object with that many faces. But, you can do it with “follow active quads”.
