UniV v3.3.6 for Blender
The Ultimate UV Editing Toolkit for Blender
Download UniV v3.3.6 today. Consequently, you can supercharge your UV editing workflow with over 100 specialized operators designed to handle every aspect of UV mapping, unwrapping, and optimization . Because professional 3D modeling demands efficient texture coordinate management, having access to a comprehensive UV toolkit is absolutely essential. Nevertheless, Blender’s native UV tools often require multiple steps and complex workflows to achieve desired results. Fortunately, UniV eliminates these frustrations completely. Moreover, it provides context-sensitive operators that adapt to your selection mode and modifier keys, ensuring maximum efficiency with minimal keystrokes . In short, you can edit UVs faster and more intuitively than ever before.
Core UV Editing and Transformation Tools
The foundation of this addon lies in its extensive collection of operators that streamline common UV tasks. For instance, the Quick Snap feature allows you to transform UV islands or geometry elements by snapping to vertices, edge centers, or face centers with just a few keystrokes . Furthermore, the Weld operator connects selected vertices by common vertices, seamlessly switching to Stitch mode when no vertices are available to connect . The Stitch operator, in turn, connects UV islands while preserving their proportions, making it ideal for assembling complex UV layouts . Additionally, the Cut operator sets mark seams along border selections while simultaneously expanding the island, eliminating the need for separate steps . Consequently, your UV editing workflow becomes significantly more fluid and efficient.
Advanced Operators for Precision and Optimization
Professional UV work often demands more than basic editing. Therefore, UniV provides a suite of advanced operators for precise control and optimization. For example, the Quadrify operator aligns selected UVs to a rectangular distribution, perfect for creating clean, grid-like layouts . Additionally, the Straight operator straightens selected edge chains while relaxing the rest of the UV island, helping you achieve clean, distortion-free mapping . The Sort and Distribute operators arrange islands for optimal packing and even spacing, crucial for maximizing texture resolution and minimizing wasted space . Finally, the Adjust & Normalize operator sets a uniform texel density across your model, ensuring consistent texture resolution .
Context-Sensitive Operators and Modifier Key Logic
Many of UniV’s operators are context-dependent, making them even more powerful. For instance, the behavior of operators changes based on your Sync state, selection mode (vertices, edges, faces, or islands), and which modifier keys (Ctrl, Shift, Alt) you hold before clicking . This contextual logic follows consistent patterns: Ctrl often invokes the “To Cursor” mode for transformations or “Deselect” for selection operators, Alt typically calls an alternative or fundamentally different operation, and Shift usually triggers “Individual” or “Inplace” modes . Since this system is designed to be intuitive, you will quickly learn to harness its full power without constantly referencing documentation.
v3.3.6 New Features and Blender 4.4 Support
Version 3.3.6 introduces several valuable additions and critical fixes for Blender 4.4. For instance, the update adds a Hide operator [H] and a Focus operator [Numpad .] for more efficient viewport navigation . Additionally, the Stretch UV Toggle [Z, Z+Z] and Show Modified UV Edges Toggle [Alt+Z] provide visual feedback for edge behavior . The Cut operator now features a Pick system and line drawer, while Flip and Rotate also gained Pick system support . Furthermore, this release fixes a context error when the active object lacked polygons and resolves a SplitUVToggle operator crash on Blender 4.4 and higher . Consequently, UniV v3.3.6 is fully compatible with modern Blender versions.
Flexible Installation and Hotkey System
UniV is designed to integrate seamlessly into your existing workflow. The addon does not impose its hotkeys on you, but you can easily enable them in Settings > Extensions > UniV > Keymaps . Some operators, due to their specificity, can only be called through keymaps, including QuickSnap, SplitUVToggle, and SyncUVToggle . Additionally, a panel appears in the lower left corner of the interface where you can adjust properties without memorizing every hotkey combination . This flexibility ensures UniV adapts to your preferred way of working.
Perfect for 3D Artists, Game Developers, and Animators
This addon is particularly well-suited for 3D artists who need efficient UV workflows for texturing and shading. Similarly, game developers optimizing assets for engines will benefit from tools like Sort, Distribute, and Adjust & Normalize. Additionally, animators and character artists will appreciate the precision tools for clean, deformation-friendly UV layouts. Ultimately, UniV v3.3.6 accelerates your entire UV editing pipeline.

UniV
Blender Addon for UV Editor which aims to cover all sorts of operators for working with UV
Align Edge by Angle – align edges by angle in Island mode.
Quick Snap – allows you to transform an island or geometry elements by Vertex, Edge Center and Face Center. There are two methods of calling the operator via the keys:
- V – quick start, the nearest transformation element is selected immediately
- Alt+V – here you can safely select the necessary element and change the modes to Island or Element mode
Stack – overlap islands with similar geometry:
Weld – [W] connects selected vertices by common vertexes, if there is nothing to connect, it works as Stitch
- Alt+Weld Button – connect by distance
Stitch – [Shift+W] connects islands to each other, preserving the islands’ proportions. When called via keymap with sync enabled, the target island becomes the closest:
Stitch with padding
Unwrap – differs from the built-in operator in that it unwrap inplace.
Relax – combination of minimize stretch and unwrap borders.
Cut – [C] – sets mark seams by border selection and at the same time expands the island
Quadrify – [E] align selected UV to rectangular distribution
Straight – [Shift+E] straighten selected edge-chain and relax the rest of the UV Island
Copy to Layer – copy coordinates between uv-channels
Adjust & Normalize – sets a uniform texel
Flatten – convert 3d coords to 2D from uv map
Focus – [F] improved focusing, which frames the focussed elements.
Crop – proportional tile filling
Fill – it is similar in everything with Crop, but without preserving the proportions
Orient – orients islands along the axes, maximally filling the area according to the boundbox. In a 3D viewport, it .
Orient3D – orients islands according to world coordinates.
Align – straightens, moves islands or vertices, places a 2D cursor on bound boxes, etc.
Sort – sorts islands, also aligns for more compactness.
Distribute – similar to Sort, but the goal is to arrange the islands evenly according to the original position
Random – randomly transforms islands to break down repetitive patterns.
Linked – [Ctrl+Shift+Mouse Scroll] – Select Linked
Cursor – Select by Cursor
Border – Select border edges
Border by Angle – Select border edges by angle from 2D
Inner – Select inner edges by mark sharps, angle
Square – Select square, horizontal or vertical island
SyncUVToggle – [~] toggle sync mode with element selection preserve
SplitUVToggle – [Shift+T] open, close, toggle UV or 3D View area
There is much more to UniV operators than you might think at first glance. Many operators are context-dependent, for example, on Sync state, selection mode (Verts, Edge, Face and Islands), as well as on pressed Ctrl, Shift, Alt (CSA) keys and combinations thereof.
That is, before pressing the LMB button press CSA, then other modes of the operator are called. And these modifications are subject to a certain logic, which in most cases works:
- Ctrl – To Cursor for transform or Deselect for select
- Alt – Alternative operation that is fundamentally different from the default.
- Shift – Individual, Inplace for transform or Extend for select
But you don’t have to use the CSA keys, because a panel appears in the lower left corner where you can change the properties
Also, the addon doesn’t impose its hotkeys on you, but you can easily enable them in Settings->Extensions->UniV->Keymaps. But some operators due to their specificity can be called only through keymaps (QuickSnap, SplitUVToggle, SyncUVToggle).
The addon is free, but you can support the author and purchase this addon from Blender Marketplace
