ULT earns its place in the Blender extensions library for concentrating batch UV layer operations, presets and selection statistics into a single sidebar panel.
UV Layers Tools (ULT) is a Blender add-on by AbstracteurDeQuinteEssence for batch UV layer management. It lets you add, rename and delete UV layers for all selected meshes at once, move layers up and down, and name layers using built-in or custom presets. You can set the active and render UV layer by index, sync active and render layers between meshes, and enable Sync Render with Active UV so the active layer is automatically used as the render UV layer for selected mesh objects.
A Statistics panel displays the number of selected meshes, non-meshes, and meshes without UV data, and shows whether UV layer counts and names match or mismatch across selected objects. Individual statistic lines can be shown or hidden via a popover, and for certain selection counts the panel displays various emoticons. You can also view and manage the active mesh's UV layers in the familiar panel within the add-on.
The add-on was developed with the help of an AI assistant. Version 1.2.0 removed the depsgraph handler and re-implemented Sync Render with Active UV with a lightweight timer that runs only when enabled. It is released under the GNU General Public License v3.0 or later.
UV Layers Tools (ULT) is best for blender artists managing UV layers across multiple selected meshes at once.
UV Layers Tools (ULT) is completely free to download and use.
UV Layers Tools (ULT) is compatible with Blender 4.5 LTS and newer, and the developer notes it has been tested and works correctly in Blender 4.5. If you are running an older release, you would need to update Blender to use the add-on. Compatibility details and any future version support are listed on the developer's GitHub page, which is the best place to confirm before installing on your setup.
UV Layers Tools (ULT) can be installed by downloading the latest zip file from the developer's Releases page, then in Blender going to Edit → Preferences → Add-ons → Install, selecting the downloaded file and installing. It can also be dragged and dropped into Blender. Once enabled, the add-on panel is located in the 3D Viewport → Sidebar (N) → ULT tab. The add-on does not require any special permissions.
UV Layers Tools (ULT) version 1.2.0 completely removed the depsgraph handler, so the add-on no longer uses depsgraph callbacks. Sync Render with Active UV was re-implemented with a lightweight timer that runs only when the option is enabled, at a 0.1 second interval, and stops immediately when disabled. The Statistics panel gained a popover to individually show or hide each statistic line, and the Meshes with Zero UV Area feature was removed. The update also includes various performance and user experience improvements.
UV Layers Tools (ULT) is listed as free here and is released under the GNU General Public License v3.0 or later. For current licensing terms and the full license text, refer to the developer's GitHub page. The add-on does not require special permissions, and its download size is small at under ten kilobytes, making it straightforward to add to an existing Blender installation.
