Brush Settings determines how a brush will affect meshes. In the image below I've used the gear icon to expand the settings panel, exposing 3 additional settings.
A) Brush Preset Selector
Click this drop-down to choose from saved Brush Presets
B) Save Brush
Save the current brush settings as a new Preset, or overwrite an existing Preset.
C) Brush Options
- Min: This is the minimum value the Radius slider will allow.
- Max: This is the maximum value the Radius slider will allow.
The outer limit of the Brush, where it's effect becomes 0%. Shown as a light-colored outer ring.
Shortcut: Control (Command) + Mouse Wheel
The zone of 100% (potential) effect for the Brush, shown as a bright blue inner ring.
Shortcut: Shift + Mouse Wheel
Strength controls the Brush's maximum effect, similar to the standard "opacity" setting commonly found in 2D painting tools.
Shortcut: Control (Command) + Shift + Mouse Wheel
The falloff curve determines how the Brush Effect drops between the Inner and Outer Radius.
Tip: This is a real curve, you can create complex brush effects here!
