Undo and history

Action	Keys
Undo	Ctrl Z
Redo	Ctrl Y or Ctrl Shift Z

The history list in the top bar shows each step by name (“Carve stroke”, “Shape stamp”, “Merge”) so you can jump back several at once.

What’s in the history

Everything: strokes, paint, masks, transforms, combining and splitting objects, adding and removing detail levels, hair strokes and photo projection. One history covers every object in the sculpt.

Each step stores only the blocks of clay that changed, so a typical step is tens of kilobytes and long sessions stay light.

Toasts that report an action (such as removing floating bits) carry their own Undo button.
