Brush scattering determines the number and placement of marks in a stroke.

Brush strokes without scattering (left) and with scattering (right)

Scatter and Control

Specifies how brush marks are distributed in a stroke. When Both Axes is selected, brush marks are distributed in a radial direction. When Both Axes is deselected, brush marks are distributed perpendicular to the stroke path.

To specify the maximum percentage of scattering, enter a value. To specify how you want to control the scattering variance of brush marks, choose an option from the Control pop‑up menu:

Off

Specifies no control over the scattering variance of brush marks.

Fade

Fades the scattering of brush marks from maximum scattering to no scattering in the specified number of steps.

Pen Pressure, Pen Tilt, Stylus Wheel, Rotation

Varies the scattering of brush marks based on the pen pressure, pen tilt, position of the pen thumbwheel, or rotation of the pen.

Count

Specifies the number of brush marks applied at each spacing interval.

Note: If you increase the count without increasing the spacing or scattering values, painting performance may decrease.

Count Jitter and Control

Specifies how the number of brush marks varies for each spacing interval. To specify the maximum percentage of brush marks applied at each spacing interval, enter a value. To specify how you want to control the count variance of brush marks, choose an option from the Control pop‑up menu:

Off

Specifies no control over the count variance of brush marks.

Fade

Fades the number of brush marks from the Count value to 1 in the specified number of steps.

Pen Pressure, Pen Tilt, Stylus Wheel, Rotation

Varies the number of brush marks based on the pen pressure, pen tilt, position of the pen thumbwheel, or rotation of the pen.
