#### Number of Streaks

High values make more streaks, which give a more detailed look. Lower values make fewer streaks and give a simpler look.

#### Streak Size

Low values give thinner, more separated streaks. High values give thicker, more overlapping streaks. A value of 0 turns the streak off.

#### Streaklet Random Seed

This control adjusts randomization within each streaklet. This helps alter the look between streaklets that might share similar parameters.

**Streak Size**

Low values give thinner, more separated streaks. High values give thicker, more overlapping streaks. A value of 0 turns the streak off.
