Brush Edit Curve

The curve controls affect brush profiles.

By default, ZBrush uses a shaped sculpting brush where the strength of the brush is strongest near the center, and drops off toward the outside of the brush. This is why the Std brush raises areas as a 'hill', not as a cylinder.

Changing the edit curve will change the effect of the brush. On the left you can see how an edit curve with multiple peaks can be used to sculpt in a specialized shape.

Using such a shape can allow you to produce very specific shapes with little work.

With the ability of ZBrush 3 to use alphas while sculpting, the need to adjust the edit curve for special effects has lessened. However, remain aware of the way the standard edit curve fades a sculpt toward the edges of a stroke.

EditCurve: The Edit Curve determines, and can modify, the brush's radial profile. The default edit curve is low at its left edge (corresponding to the outside of the brush), and high at its right edge (corresponding to the center of the brush), causing strokes to affect the model more strongly at the center of the brush, and less strongly at its edge. As with all curves, click the edit curve to expand it for modification, and click on Close to collapse it again.
