UV
6 checks, listed alphabetically.
Active UV Map Present
Checks that mesh objects with polygons have at least one UV map and that a valid UV map is active.
UV Area Valid
Checks for UV faces with zero or collapsed UV area.
UV Orientation
Checks all UV maps for flipped or mirrored UV faces.
UV Overlap
Checks UV maps for overlapping UV faces using Blender's native UV overlap operator. By default, only each mesh's active UV map is checked; scanning every UV map is available as a setting.
UV Within Bounds
Checks all UV maps for UV coordinates outside the primary 0-1 tile.
Valid UV Assigned
Checks that every polygon has meaningful UV coordinates across all UV maps.
