If you want to lengthen a tube, hover over the end of the current curve until a red line appears, then drag to continue the tube from that point.
When using the brush (or any curve-based brush like CurveStrap, CurveTube, etc.), ZBrush allows you to see the full 3D mesh preview as you draw the curve — before releasing the mouse/stylus.
Open your Brush palette and select CurveTube (or CurveTubeSnap for better surface adhesion). zbrush curve tube
When you first draw a curve tube, it is a "Live" curve. You can edit the points, but it isn't final geometry yet. To convert it into a polymesh that you can sculpt on:
If you want the tube to conform perfectly to a surface, ensure Snap is enabled under . For precise, close-fitting results, use the CurveTubeSnap brush, which often works better than the default CurveTube for adhering to complex, high-poly surfaces. B. Changing Tube Thickness (Tapering) If you want to lengthen a tube, hover
The ZBrush brush is an indispensable tool for 3D artists, offering a rapid, intuitive way to create complex tubular structures, cables, straps, pipes, and organic tendrils. Unlike traditional modeling, which requires tedious edge-extrusion, the Curve Tube allows you to draw a path, and ZBrush automatically generates 3D geometry along it.
A tube without an end cap looks unnatural. ZBrush solves this with . When you first draw a curve tube, it is a "Live" curve
To access the Curve Tube functionality, you generally do not select a brush named "Curve Tube." Instead, you activate within specific brushes.
