// What it does
Scans your paint for small same-colour islands and stray single triangles — a fleck of the wrong colour where its neighbours all disagree. Each one gets a magenta dot at its centre, plus a magenta overlay up close. A spinner shows while it scans. Nothing is repainted yet — this step only flags, so you can look before you commit.
// When to use it
- After any large brush stroke or Magic Fill pass — quick QA before export.
- After Plane paint or Direction paint, where bulk operations sometimes flip a single odd-normal triangle to the wrong colour.
- Before exporting a 3MF — a stray fleck slices as the wrong filament, not what you intended.
// How to use it
- Mark an area first (optional) to limit the scan to one region — otherwise it scans the whole model.
- Check tab → Find speckles. A spinner runs, then magenta dots land on every stray triangle.
- Zoom in and check the dots. Happy? Clean speckles repaints each one to the colour around it — see Clean speckles.
// Tips
- Mark an area first to narrow the scan. On a busy model it's quicker to check one region at a time than the whole mesh at once.
- Max speck size sets how big a same-colour island can be before it's left alone (default 10 faces). Raise it to catch larger blobs; drop it to flag only the tiniest flecks.
- For bare unpainted holes — not a wrong colour, just nothing painted — use Fill bare gaps instead.
