Sets curve smoothness. The higher the degree, the smoother the resulting curve, at a cost of slower calculations.

Defines the intensity of a stroke generated with Stroke On Curve. The left end of the curve corresponds with the beginning of the stroke. The right end represents the end of the stroke. By default, the stroke fades in and out.

You can edit the Intensity Variation curve the same way you edit curves for tool falloff or to adjust color. See Adjust tool falloff for information on editing curves.
