UV Layers Tools (ULT)

Batch UV layer management for Blender.

Add-on by AbstracteurDeQuinteEssence

Version History

1.2.0

Compatibility

depsgraph handler completely removed
The add‑on no longer uses any depsgraph callbacks.
Sync Render with Active UV re‑implemented with a lightweight timer
The timer runs only when the option is enabled (0.1 s interval) and stops immediately when disabled. It checks the active UV layer of each selected mesh and updates the render UV layer accordingly.
Statistics improvements
Added a popover to the new Statistics panel, allowing users to individually show/hide each statistic line: Emoticons, Mesh count, Non‑Mesh count, Meshes without UV, UV Count Mismatch, UV Names Mismatch, and UV Layers Match.
Removed “Meshes with Zero UV Area” feature
The functionality did not fit the core concept of the add‑on (UV layer management, not UV data analysis).
Various improvements for better add‑on performance and user experience

Compatibility

Removed redundant operators
Select All Meshes, Deselect Non-Meshes, Add/Remove Active UV (replaced with native buttons).
Replaced More Info / Less Info buttons with a single Info Display checkbox
Statistics and emoticons are now computed only when Info Display is enabled – no performance impact otherwise.
New Info Display stat
Meshes with Zero UV Area.
Added a Selection Tools menu with two commands:
Select Meshes without UV
Select Meshes with Zero UV Area, which has two modes: all islands (bounding box method) and any island (checks every polygon individually).
Improved UV Name presets
Preset names require ASCII, so non‑ASCII characters are now silently removed to keep the preset valid.
General UI polish
Various refinements for a cleaner look.
Multiple minor fixes and stability improvements
