About UV Online Inspector

Draws the UV layout as a 1024×1024 PNG wireframe: blue for normal triangles, red for overflow (UV outside the 0–1 range), violet for true geometric overlap (actual segment intersection, not just bounding box hit), orange for high stretch (UV area / 3D area ratio > 4× the median). Also reports total UV triangles, missing-UV, degenerate UVs, max stretch ratio. Essential for marketplace listing, pre-bake QA, source check before Substance Painter / Marmoset.
