UV Shortest Mark¶
Marks seams, sharp edges, crease or bevel weight along the shortest path across the mesh, stopping at barrier edges you already marked. In Build mode click a start vertex and then a target to lay down a chain; in Direction mode hover an edge and the path runs forward until it hits a barrier. Tune the route with flow, smoothing, curvature and arch, or re-route all existing marks through smoother edges. Edit Mesh mode.
Hotkey: Not bound by default — assign a key in Preferences › iOps › Keymaps, or run it from the iOps pie / operator search.
Controls¶
| Key | Action |
|---|---|
| Move mouse | Preview the path |
| LMB | Build: set the anchor, then apply and chain onward. Direction: apply the previewed path |
| Q | Start a new chain |
| Ctrl+Q | Switch Build ↔ Direction |
| E | Cycle barrier type: Seam → Sharp → Crease → Bevel Weight |
| R | Cycle mark type |
| A | Cycle path algorithm (Dijkstra → A* → Edge Loop) |
| S | Mark / unmark all edges sharper than the angle threshold |
| D | Clear marks along the previewed path |
| F | Smooth Marked: re-route existing marks (see below) |
| Ctrl+Wheel | Flow angle |
| Shift+Wheel | Smooth level |
| Alt+Wheel | Sharp angle threshold |
| Ctrl+Shift+Wheel | Curvature bias (convex ↔ concave) |
| Ctrl+Alt+Wheel | Arch strength (Build mode) |
| Ctrl+Z | Undo the last mark |
| MMB / Wheel | Navigate the viewport |
| H | Show / hide the help legend |
| Space / Enter | Finish |
| Esc | Cancel |
Smooth Marked (after F): Alt+Wheel magnet, Shift+Wheel iterations, Space / Enter accept the proposed route, F / Esc back without changes.
Tips¶
- Your barrier, mark, algorithm and tuning settings are remembered for the next run.
- A Triangulate modifier is hidden while the tool runs so you pick on the real geometry.
