// What it does
Pairs faces across an axis of symmetry. Once paired, every paint action — Region, Brush, Wand, Detail, Mark area, even bulk paints — applies to both the face and its mirror image.
Modes: X (left ↔ right), Y (top ↔ bottom), Z (front ↔ back), or off.
// When to use it
- Symmetric models — humanoids, vehicles, busts. Half the work.
- Repeating patterns where one half mirrors the other.
- Even slightly asymmetric models — pairs what is symmetric, leaves the rest manual.
// How to use it
- Setup tab → Symmetry → click an axis (X for left/right is most common).
- Status reads
N faces paired— confirms the model actually has symmetry to use. - Paint normally. Region click on the left, the right mirrors. Brush drag, the other side draws live.
- Switch off by clicking the same axis again.
// Tips
- Model not actually symmetric? Paired count is low or zero. Layerpaint can't fix asymmetric meshes — turn it off.
- Wrong axis? If symmetric across Y but you picked X, nothing pairs. Try the other axes.
- Forgetting symmetry is on is a common gotcha. Watch the indicator if your strokes seem to do too much.
