How to use this UV map inspector

Use this UV diagnostics tool when you need to review UV island quality, overlaps, seams, and UDIM coverage directly in-browser.

  • Upload GLB, GLTF, FBX, OBJ, STL, or PLY and inspect UV channels in synchronized 3D and 2D view.
  • Enable overlap, flipped, stacked, mirrored, distortion, and texel density diagnostics to isolate layout issues.
  • Preview checker maps or your own texture beneath the UV layout before fixing or exporting assets.

FAQ

How do I inspect UV overlaps and seams online?

Upload a UV-mapped 3D model, choose the UV channel you want to inspect, then enable overlap and seam diagnostics to highlight issues in both 2D and 3D.

Can I preview a checker map or my own texture over the UV layout?

Yes. You can switch checker presets and resolutions, or drop a local texture onto the UV canvas to preview it beneath the UV outlines.

Does this UV inspector support UDIM layouts?

Yes. When UVs extend beyond the base 1001 tile, the inspector can show the occupied UDIM tile range and keep diagnostics aligned to that overview.
