Visual UV¶
Edit UV islands directly on the model in the 3D Viewport. Islands on the selected faces are colour-coded and the active one shows a bounding box with handles, a pivot and a rotation knob; grab, rotate, scale, flip, align, randomise or unwrap them without opening the UV Editor. Edit Mesh mode with faces selected.
Hotkey: Ctrl+Alt+U (Edit Mesh). Also available: iOps Edit Pie › Visual UV.
Controls¶
| Key | Action |
|---|---|
| LMB on an island | Make it the active island |
| LMB on a handle / knob | Scale / rotate by dragging the handle |
| Tab | Cycle the active island |
| G / R / S | Grab / Rotate / Scale around the pivot (hover a handle to use it as the pivot) |
| X / Y | Lock an axis while transforming |
| Shift | Constrain to the dominant axis (grab) / uniform scale |
| Ctrl | Snap: 1/16 UV steps, rotation step, 0.05 scale |
| Ctrl+Wheel | Change the rotation snap step (1…90°) |
| Alt+Wheel | Mouse sensitivity |
| C / P | Place the UV cursor / toggle pivot Center ↔ Cursor |
| A | Align selected islands to the active one's hovered handle, or pick an edge to align to |
| I | Transform scope: All islands ↔ Active only (affects G / R / S / F / N) |
| F / Shift+F | Flip horizontal / vertical |
| D / Shift+D / Ctrl+D | Fit selected islands onto the active one: islands transposed against it (landscape vs portrait) are turned 90° first, then their bounding box is scaled to the active island's box (both axes / width only / height only) and centred on it |
| N / Shift+N / Ctrl+N | Randomise offset: both axes / U only / V only |
| U | Unwrap the selection |
| T | Straighten the UV edge chain under the cursor |
| E | Stitch: click a source edge, then move the mouse; the island is scaled, rotated and moved live onto the nearest edge of any other UV island (selected or not). LMB confirms, RMB cancels, hold Shift to land on the same side (overlap) |
| Q | Clean view: hide overlays |
| Ctrl+Z / Ctrl+Shift+Z | Undo / redo inside the session |
| RMB | Cancel the current transform |
| MMB / Wheel | Navigate the viewport |
| H | Show / hide the help legend |
| Enter / Space | Confirm |
| Esc | Cancel and restore the original UVs |
Options¶
- Tile Limit — how many tiles an island may drift from 0–1 before it is re-centred.
- Rotation Step — snap step for Ctrl-rotate.
- Grab Sensitivity — mouse-to-UV multiplier.
Tips¶
- Each island shows its texel density next to its centre.
