// What it does
Click any painted patch. The patch expands outward one ring of triangles at a time until it hits a different colour. The new ring takes the colour of the patch you clicked.
Turn on Stop at crease and it also halts at hard edges, so the colour can't spill over a sharp lip onto the next face.
// When to use it
- Discard-risk fix-up. A patch flagged as too narrow for the slicer — Grow it to safe width before export.
- Repairing a patch that's almost the right size but a little too small.
- Pushing a band of colour into a gap.
// How to use it
- Press
Puntil Grow. - Click the patch. Watch it pulse outward — one ring per click — until it hits other colour.
- Tool panel → Stop at: pick Auto (halts at whichever colour dominates) or a specific palette entry (grows only until it meets that one colour).
- Stop at crease. Toggle this on and Grow also halts at hard edges. Set Sharp above to the angle that counts as a crease — raise it to ignore gentle curves, lower it to catch subtler ridges.
- Verify with the Discard-risk overlay — the previously red-flagged patch should now show clear.
// Tips
- Clicking unpainted ground does nothing. Grow needs a painted patch as the seed.
- For wholesale repaint, just use the brush. Grow is for surgical widening.
- Grow walks the mesh until the colour changes — a drawn border won't stop it, but a crease will if Stop at crease is on.
