Undo history.

Don't Ctrl+Z 47 times. Open the timeline, pick the moment, snap there.

// What it does

A labelled timeline of every undoable action this session: each entry is named ('Brush (Red)', 'Wand fill (Gold)', 'Process discards', 'Mark area paint'). Click any entry — the mesh snaps to that state.

Ctrl+Y or Ctrl+Shift+Z redoes forward from there.

// When to use it
  • Reverting many actions at once when Ctrl+Z-spam is tedious.
  • Reviewing what you actually did this session (visual changelog).
  • Branching: snap back, try a different approach, and the new actions overwrite the future.
// How to use it
  1. Press Ctrl+H (or panel footer → History). Modal opens with the timeline.
  2. Click any past entry — mesh snaps to that state.
  3. Ctrl+Y to step forward.
  4. Painting from a past state overwrites the future — common gotcha.
  5. Escape closes the modal.
// Tips
  • Painting after travelling back overwrites the actions that were ahead — they're gone.
  • History resets on reload. The persistent state is the .layerpaint file.
