I don't call it a crime, I call it an insult to geometry. A half‑wrapped canvas is like a broken mirror—no symmetry, no balance. Fast art may look fine on the surface, but when you pull up the UV map you’ll see a chaotic mess. If you want to win the texture game, you’ll have to respect the lines. Or you can keep using auto mapping and keep your textures looking like a bad tattoo. Either way, the only thing that matters is precision.
