ZBrush Tip: Bend Curve Workflow for Precise Organic Bends

Use Transpose Line > Bend Curve to shape cables, tails, straps, and limbs with precise, organic falloff—fast, controllable, and repeatable.

1. Prepare the mesh
   • Isolate the target SubTool and clean up topology if needed (Decimation or ZRemesher for even response).
   • Define control regions with Polygroups or a crisp mask; Bend Curve respects masks and visible geometry.
   • If scale feels off, run Deformation > Unify for predictable deformer behavior.
2. Launch Bend Curve
   • Press W to show Gizmo 3D (or switch to the classic Transpose Line if you prefer its handle workflow).
   • Click the Gizmo gear icon and choose Bend Curve. ZBrush displays a manipulable curve aligned to the Gizmo.
   • Alt-click a surface to relocate the Gizmo and align it to a meaningful normal before invoking Bend Curve. Good alignment = cleaner bends.
3. Set up control and falloff
   • Increase the curve’s control points until the transition looks smooth across your length; fewer points for broad sweeps, more for nuanced S-bends.
   • Keep endpoints near areas you want anchored. If necessary, hard-mask those anchor zones first.
   • For symmetrical edits (horns, whiskers, mech tubes), enable Transform > Symmetry or Local Symmetry as appropriate before bending.
4. Bend with intent
   • Drag the curve’s control points to shape the form. Interior points create gentle arcs; moving an endpoint affects the overall sweep.
   • Use small, incremental moves to avoid kinks; redistribute points along the length if tension concentrates in one area.
   • If a section must remain rigid (a connector or buckle), protect it with a mask or split it into a temporary SubTool.
5. Commit and iterate
   • Accept to apply, or Cancel to try different pivot/curve placements.
   • For non-destructive flexibility, store the operation on a Layer and/or duplicate the SubTool beforehand.
   • Working on full characters? Use Transpose Master to create a proxy, apply Bend Curve once, then transfer back to all SubTools reliably.

• Quick use cases: eyelash arcs, braided cables, leather straps around armor, organic tails/tentacles, fins and feathers, hoses between mech panels.
• Refinement combo: after bending, lightly HPolish or Smooth Stronger to unify planes without eroding the silhouette.
• Troubleshooting: stepped deformation usually means too few control points or uneven density—add points or ZRemesh. If the bend flips unexpectedly, re-center/realign the Gizmo and try again.
• Workflow tip: Save an Increment just before the bend. Iterating different curve placements is faster than trying to “fix” a poor pivot.

Keep Bend Curve in your daily toolkit to replace time-consuming Move-stroke nudging with clean, art-directable arcs.
