Question 1

How do I inspect UV overlaps and seams online?

Accepted Answer

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.

Question 2

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

Accepted Answer

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

Question 3

Does this UV inspector support UDIM layouts?

Accepted Answer

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.
