A technique for smoothing an entire object all at once –
- Using selection mask, mask the entire object.
- Set thickness height to 0./
- Turn on smoothing and set to desired amount. (For hard surface modeling, it will smooth out visible angle changes in the polygons.)
- Set closing action to “none”.
- Hit the extract button. Hide or delete original object.
- Play around “all”, “sharp border”, and “borders only” options
