Noise Scale

Controls the smoothness of the stroke drawn around outside edges and features on models. Has no effect when Noise Amplitude is set to 0.

Noise Amplitude

Controls the distortion of the stroke drawn along outside edges and features on models. Works with Noise Scale.

Pencil Scale

Controls the thickness of the stroke drawn along the outside perimeter of objects in the 3D View.

Fill Noise Amplitude

Controls the smoothness of the fill regions that are drawn for models in the 3D View. Increasing this value makes the fill bleed outside of the stroke region, like watercolor paint.

Fill Paper Noise Amplitude

Applies a rubbing effect on the textured background to enhance the effect of a textured paper. When Fray Strength is set to 0, this feature has no effect.

Gradient Width

Increases the buildup of the rubbing effect produced by the Fill Paper Noise Amplitude property. For use with Fill Paper Noise Amplitude and Fray Strength.

Fray Strength

Increases or decreases the effect produced by the Fill Paper Noise Amplitude property.
