Spiral brush settings

These options appear as a subset of the Tubes > Behavior section in the Paint Effects Brush Settings window, and the Attribute Editor for any brush node.

Spiraling occurs when tubes are wrapped around the stroke normal.

Spiral Min, Spiral Max

Defines the minimum and maximum amount of spiraling that occurs around the stroke normal. Paint Effects randomly chooses values within this range for newly created tubes.

Spiral Decay

Defines how the amount of spiraling (tightness) decays from the beginning to the end of a tube. If the value is 0, the spiral is constant. Values greater than 0 produce tighter spirals, Values less than 0 produce looser spirals.
