Hatch Brushes
Sculpt back and forth in a single stroke for precision
Hatch brushes offer the ability to apply sculpting strokes in a back and forth motion without picking up your cursor, but only add or subtracting in the forward direction of the stroke. This functionality makes it easy to apply sculpting strokes in a sketch-like fashion. It also reduces adding or subtracting too quickly from a surface, helping give brush stroke precision.
Hatch Brushes & How They Work
All Hatch brushes use the Stroke >> Modifiers >> No Back&Forth mode. To learn more about No Back&Forth mode, search for it at docs.pixologic.com or in the ZBrush Documentation Guide PDF found in the root ZBrush folder.
There two of these brush types > Hatch Brush, and HatchBackTrack Brush.
1. Hatch Brush
The start of your brush stroke establishes its direction. The initial direction of movement is the forward progression.
While applying strokes in a back and forth motion without picking up your cursor, the stroke can only add or subtract in the forward direction established by the first part of the stroke.
2. HatchBackTrack Brush
This brush utilizes No Back&Forth mode along with Stroke >> Lazy Mouse >> Backtrack. This creates a ramp effect in the sculpted details.
The start of your brush stroke establishes its direction. The initial direction of movement is the forward progression. While moving the cursor in a back and forth motion without picking it up, the stroke can only add or subtract in the forward progress direction established at the beginning of the stroke, while still applying the Backtrack ramp effect
