Selection
A selection limits painting to a region of the surface — paint only inside (or outside) it. You can also turn a selection into a layer mask.
Selection modes
Pick the Select tool, then choose a mode:
| Mode | How it works |
|---|---|
| Brush (paint-select) | Brush the selection onto the surface like paint. Hidden geometry isn't selected. |
| Lasso | Drag a freehand outline; the enclosed area is selected. |
| Polyline | Click points to build a straight-edged outline; double-click or Enter to close it, Esc to cancel. |
| Rectangle | Drag two opposite corners. |
Add, subtract, replace
By default a new selection replaces the old one. Hold a modifier while you select to combine instead:
| Action | Modifier |
|---|---|
| Add to selection | Shift |
| Subtract from selection | Ctrl |
Ctrl+A), Deselect (Ctrl+D) to clear,
Reselect (Ctrl+Shift+D), Invert
(Ctrl+Shift+I), and Grow / Shrink /
Feather to refine the edge.Selecting in the 2D view
All four modes work in the 2D UV view too, which can be easier for UV-island-accurate selections. The same Shift / Ctrl modifiers apply, and a selection made in either view shows in both.
Selection → mask
Choose Select › Selection to Mask to turn the current selection into a layer mask on the active layer, so a selection you made once drives where that layer shows. Select › Mask to Selection does the reverse — it loads the active layer's mask back into the selection.
