// What it does
A context menu scoped to whatever face you right-clicked. Header shows the region number and face count. Region-scoped actions: Paint this region · Mark this region · Simplify this region · Pick this colour · Replace this colour → current · Select all with this colour.
Whole-mesh shortcuts: Fill borders (whole mesh) · Find gaps (whole mesh) · Preview simplify · Reset view.
Escape closes the menu without action.
// When to use it
- Mid-paint shortcuts — no tab switch.
- Bulk selection by colour — Select all + a follow-up cleanup is faster than re-painting.
- One-off region simplify when you don't want to scope a marked area.
- Whole-mesh ops without losing your current tool/colour.
// How to use it
- Right-click a face on the model. Menu pops with region # in header.
- Pick this colour updates the active palette slot.
- Right-click another face → Replace this colour → current bulk re-colours every face of that colour.
- Select all with this colour turns the marked area into every face of one colour — pair with Clean edges scoped to that selection.
// Tips
- Read the header — region-scoped actions act on that region; lower group affects everything.
- Simplify this region uses the current flatness threshold from the Export tab. Lower it before simplifying if you want to preserve detail.
