UniV earns its place in the blender_extensions library by folding a wide set of UV operators into one add-on, with each tool adapting to Sync state, selection mode and modifier keys rather than spreading the work across separate buttons.
UniV is a Blender add-on aimed at covering all sorts of operators for working with UV in the UV Editor. Its behaviour is context-dependent: many operators change based on Sync state, the active selection mode (Verts, Edge, Face or Islands), and whether Ctrl, Shift or Alt are held before pressing the mouse button. Those modifier keys follow a consistent logic — Ctrl for To Cursor or Deselect, Alt for an alternative operation, and Shift for Individual, Inplace or Extend. A panel in the lower left corner lets you change the same properties without using the keys.
The toolset spans transform, selection and layout tasks, including Quick Snap, Stack, Weld, Stitch, Unwrap, Relax, Cut, Quadrify, Straight, Sort, Distribute, Orient, Align, Random and Flatten, along with selection operators such as Linked, Border and Square.
UniV doesn't impose its hotkeys; you can enable them under Settings → Extensions → UniV → Keymaps, though some operators such as QuickSnap, SplitUVToggle and SyncUVToggle are called only through keymaps. Version 4.0.0 works with Blender 4.2 LTS and newer and is released under the GNU General Public License v3.0 or later.
UniV is best for uV mapping work in Blender's UV Editor — unwrapping, stitching and arranging islands with operators that adapt to selection mode and modifier keys.
UniV is completely free to download and use.
UniV supports Blender 4.2 LTS and newer, so 4.2 and later releases are covered. The version listed here is 4.0.0. If you're running a build older than 4.2 LTS, update Blender before installing, since the add-on targets that baseline. For the exact list of Blender versions the developer has validated, including any newer builds, check the project page on GitHub at github.com/Oxicid/UniV.
UniV doesn't impose its own hotkeys, so nothing is bound until you choose to turn them on. You can enable the keymaps under Settings → Extensions → UniV → Keymaps. Keep in mind that a few operators — QuickSnap, SplitUVToggle and SyncUVToggle — can only be called through keymaps because of how they work, so enabling the keymaps is the way to reach them. For operators that expose properties, a panel appears in the lower left corner where you can adjust settings directly.
UniV is listed as free in this catalog, with a free download available from GitHub and the Blender Extension platform. The developer also offers it through Gumroad and Blender Market. Because licensing and distribution options can change, check the developer's page for the current terms before you settle on one. The add-on itself is distributed under the GNU General Public License v3.0 or later.
UniV is released under the GNU General Public License v3.0 or later, and its source is published on GitHub at github.com/Oxicid/UniV. That license governs how you can use, modify and redistribute the add-on's code. If you plan to fork it, redistribute a modified build, or include it in another project, review the GPL v3.0 terms so your usage stays compliant with its requirements.
UniV 4.0.0 is a major update that fixes numerous operators affected by the updated UV Sync Selection mode and changes to the Geometry Nodes API. It adds Texel Density support for Unwrap, Relax, Quadrify and Straight, expands support for non-square textures through Aspect Ratio, and adds more 3D View counterparts for existing UV operators. Many operators now work without an active object, and the release introduces a Specific operators tab with tools such as Random Color, Linear Gradient, Snap to Pixels, Smart Scale Apply and Add Align Border Verts.
