UV Layers Tools (ULT)
UV Layers Tools (ULT)
ULT — a Blender add-on for batch UV layer management.
Features
- Add, rename and delete UV layers for all selected meshes.
- Move UV layers up and down for all selected meshes.
- Name UV layers using presets (built‑in or custom) for all selected meshes.
- Statistics: displays the number of selected meshes, non‑meshes, meshes without UV data. Shows whether UV layer counts and names match or mismatch across selected objects. For certain selection counts, the panel displays various emoticons (・｀ω´・)
- Set active/render UV layer by index for all selected meshes.
- Sync active/render UV layer between meshes.
- Sync Render with Active UV (checkbox): when enabled, the active UV layer is automatically used as the render UV layer for any mesh objects you select.
- View and manage UV layers of the active mesh using the familiar panel – right in the add-on.
Notes
This add-on was developed with the help of AI assistant.
What's New
1.2.0 May 16th, 2026
Version 1.2 changes
depsgraphhandler 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
