Hi, I understand English badly but I really need some help. I added Mark Seams, applied all transformations, and for the subdivision, I've chosen UV Smooth to all but I still have this distortion after UV unwrapping and I don't know how to fix that. I tried so many methods on Youtube but no one is helping me.
