Changelog

This is a major update that fixes numerous operators affected by the updated UV Sync Selection mode and changes to the Geometry Nodes API.

Many operators have also gained significant improvements and new capabilities, including Texel Density support (for Unwrap, Relax, Quadrify, Straight), expanded support for non-square textures (Aspect Ratio), more 3D View counterparts for existing UV operators, reduced context dependencies (many operators now work without an active object), as well as various performance and workflow improvements.

The update also introduces Specific Operators - a collection of specialized tools designed for less common but valuable tasks. They add useful functionality without cluttering the UI.

Changelog

This update includes a tremendous amount of work to support Blender 5.0 with its long-awaited synchronized UV mode. Thanks to a few clever tricks, older versions - all the way back to Blender 3.2 - are still supported.

Overall performance of the add-on has been preserved and even improved in some areas.

Many operators in Blender 5.0 do not switch to Face Mode when deselecting (which served to avoid deselecting random elements).

Despite the need to support the new selection system - which took a significant amount of time - the long-awaited Symmetrize operator has been added. In addition, performance has been improved, bugs have been fixed, and the behavior of many operators has been refined.

Several operators also received the new View Box Sync Block system, which clips accidentally selected verts and edges based on the visible area. With Blender 5.0 this feature is less relevant, but for those who can’t upgrade yet, it's an excellent helper.

Add:

• Blender 5.0 compatibility
• Add prototype View Box Sync Block system (for Align and Orient)
• Add Symmetrize [Alt+X] operator
• UI: Added collapsible subpanels

Improve:

• Blender 5.0: Mode Set [1, 2, 3, 4] - button 4 emulates switching to island mode
• Pick System: SpeedUp x1.5 found nearest edge for Blender 5.0
• Straight: Support old sync mode and performance improvement
• Quadrify: Improved best-face detection for initial quadrification
• UI: improved subpanels order in the 3D viewport for consistency with 2D
• Added the ability to set custom texture resolution for TD presets
• Focus: Takes the T-Panel into account
• Pin: Add Toggle system instead Set/Clear
• Make addon settings independent of the scene
• Weld: Improve performance and revert report info and very small distances are connected
• Border: Improve performance, handle very small distance matching, and fix selected UV face iteration

Fix:

• Inspect: Flip: Fixed incorrect behavior caused by loss of float precision
• SplitUVToggle [Shift+T]: Fix crash if the area object was already deleted (caused by a quick tap)
• Select Linked: Fix: Delimit is no longer set automatically in Normal mode
• QuickSnap | Drag: Add snap by Cursor
• Fix keymaps menu for older version
• Align: Fix calling CENTER | HORIZONTAL | VERTICAL in elem mode when all vertices deselected
• Focus: Unselected vertices and edges no longer affect operations in face mode
• Flatten: Fix GN for Blender 5.0
• Unwrap: Fix error when calling operator without selected geometry

Removed:

• Align: Remove Cursor Align (use Set Cursor 2D [Ctrl+Shift+MiddleMouse] instead)
