ScribeStandard and ScribeChisel Brushes
On the left, ScribeChisel; on the right, ScribeStandard.
The ScribeStandard and ScribeChisel brushes both take advantage of the Curve Sub-Steps slider. The brushes use DragDot stroke. You can adjust the Curve>SubSteps to change result; low values will show the separate alpha instances. Use the Curve Modifiers graph to change the beginning-to-end shape of the scribed line.
