Flow Particle brushes

Flow Particle brushes emit short-lived particles that flow out from the center of the brushstroke across the canvas and gradually fade. Their movement resembles that of fireworks. As they flow, they encounter forces that change their path, resulting in a chaotic or controlled movement. The Flow brushes are easily influenced by force, chaos, and flow maps. For more information about flow maps, see Applying and adjusting flow maps.

Flow Particle brushstrokes

Flow brushes include the following variants:

Flow Particle brush controls

You can customize Flow Particle brushes by using the Flow Particles control panel, which includes the Position Jitter, Randomize Chaos, and Enhance Flow Map controls.

The Position Jitter slider lets you vary the starting position of the particles. You can also associate the position jitter with an expression by choosing an option from the Expression list box. For more information about Expression controls, see Expression settings.

The Randomize Chaos check box lets you change the chaos pattern randomly for a more organic look.

The Enhance Flow Map controls include the Edge slider and the Brightness slider, which modify the brushstroke based on the edge and brightness of the flow map.
