Spring Particle brush controls
You can customize Spring Particle brushes by using the Spring Particles control panel, which includes the Appearance, Stiffness, Stiffness Jitter, Length Jitter, and Minimum Length controls.
The Appearance controls let you choose a Nucleus, Chain, or Geometric appearance for the particle pattern.
• | Nucleus — Particles spring outward from the brush path. |
• | Chain — A chain of particles whips around the brush path. |
• | Geometric — Particles form a geometric shape around the brush path. |

The Random Length slider randomly varies the length of individual springs. Once adjusted, the lengths remain constant during the brushstroke.

The Stiffness slider controls the strength of the springs. Low values produce more relaxed springs, which allows the particles to move more freely in relation to each other. You can also associate the stiffness with an expression by choosing an option from the Expression list box. The Stiffness Jitter slider randomly varies the strength of individual springs.

You can also link stiffness to audio input from your microphone, or internal audio such as streaming music. For more information, see Audio Expression.

The Minimum Length slider sets the initial length of the springs. Low values allow springs to stretch more.
