This brush is useful for building and removing volumes and shapes like real clay, because it flattens details as you add/subtract from the surfaces.
If used together with Dyntopo it’s easy to continuously build shapes, even in a single stroke.
Slightly higher by default. This makes the profile of the brush more noticeable. More info at Hardness
Enabled by default for a consistent smoothing effect. With lower brush strength (for example with lower pen pressure) the smoothing effect will be more noticeable and can be used to create and then blend/polish shapes in a single stroke. Enable Pressure to modulate the use of auto-smooth even more with pen inputs. More info at Auto-Smooth
