Common Particle brush controls

Brush controls common to all Particle brushes are accessible through the Particles - Common control panel.

The Count slider sets the number of particles in a brushstroke, and in turn the number of paths rendered during the stroke.

Low count (left) and high count (right)

The Global Chaos slider applies chaos to all particles equally, so that they move chaotically but in unison. The Local Chaos slider randomly applies chaos to individual particles in the brush. The Smoothness slider smooths the chaos for a more organic look. You can also associate global and local chaos with an expression.

The Damping slider allows or inhibits particle movement. Low damping allows particles to move faster and be more responsive to any forces affecting their movement. High damping reduces all forces affecting particle movement, and the movement itself becomes slow and heavy. The Damping Jitter slider applies damping at random to individual particles.

The Force slider applies global directional force to all particle movement. The effect is similar to the effect of wind on watercolor. The Direction slider sets the direction of the global force in degrees. You can also associate force and direction with an expression.

Left: Low force, direction at 0. Right: High force, direction at 90.

The Flow Map slider sets the degree to which particle movement is affected by the flow map. For more information about flow maps, see Applying and adjusting flow maps.
