Click on the Randomize button to randomly select a new seed value, or adjust the slider to manually select a new seed value.

This value represents the Friction force applied to the particle's Velocity. The larger the value, the greater the Friction, thus slowing down the particle.

This value represents the Friction force applied to the particle's rotation or Spin. The larger the value, the greater the friction, thus slowing down the rotation of the particle.
