Brush shape dynamics
Shape dynamics determine the variance of brush marks in a stroke.
Brush stokes without shape dynamics and with shape dynamics
Size Jitter and Control
Specifies how the size of brush marks vary in a stroke. For more information, see “Adding
To specify the maximum percentage of jittering, type a number or use the slider to enter a value. To specify how you
want to control the size variance of brush marks, choose an option from the Control pop-up menu:
•
Off
Specifies no control over the size variance of brush marks.
•
Fade
Fades the size of brush marks between the initial diameter and the minimum diameter in the specified
number of steps. Each step is equal to one mark of the brush tip. The value can range from 1 to 9999. For example,
entering 10 steps produces a fade in 10 increments.
•
Pen Pressure, Pen Tilt, Stylus Wheel
Varies the size of brush marks between the initial diameter and the minimum
diameter based on the pen pressure, pen tilt, or position of the pen thumbwheel.
Minimum Diameter
Specifies the minimum percentage by which brush marks can scale when Size Jitter or Size
Control is enabled. Type a number, or use the slider to enter a value that is a percentage of the brush tip diameter.
Tilt Scale
Specifies the scale factor applied to the height of the brush prior to rotation when Size Control is set to Pen
Tilt. Type a number, or use the slider to enter a value that is a percentage of the brush diameter.
Angle Jitter and Control
Specifies how the angle of brush marks varies in a stroke. To specify the maximum
percentage of jittering, enter a value that is a percentage of 360 degrees. To specify how you want to control the angle
variance of brush marks, choose an option from the Control pop-up menu:
•
Off
Specifies no control over the angle variance of brush marks.
•
Fade
Fades the angle of brush marks between 0 and 360 degrees in the specified number of steps.
•
Pen Pressure, Pen Tilt, Stylus Wheel, Rotation
Varies the angle of brush marks between 0 and 360 degrees based
on the pen pressure, pen tilt, position of the pen thumbwheel, or rotation of the pen.
•
Initial Direction
Bases the angle of brush marks on the initial direction of the brush stroke.
•
Direction
Bases the angle of brush marks on the direction of the brush stroke.
