ZBrush Tip: ZBrush Insert Curve Workflow for Surface‑Conforming Pipes and Wires

Use Insert Curve brushes to lay down pipes and wires that hug your surface, stay editable, and finish with production‑ready cleanliness.

• Setup
  • Pick an IMM Curve brush: CurveTube or CurveTubeSnap are ideal for round wires. For surface‑conforming runs, prefer CurveTubeSnap (it snaps to the mesh).
  • Enable LazyMouse (Brush > Stroke > LazyMouse) for smoother, wobble‑free paths. Adjust LazyRadius and LazyStep for long, controlled runs.
  • Set diameter with Draw Size. For consistent world‑scale thickness, disable Dynamic brush scale (Brush > Depth > Dynamic off).
• Draw and edit curves
  • Drag on the surface to create the curve; the tube generates instantly.
  • Click‑drag a segment to reposition locally. Hold Alt on a curve point to toggle a sharp corner for crisp bends around panel edges.
  • Use Stroke > Curve Modifiers > Size to taper ends; fine‑tune with the graph for cable tips or hose fittings.
  • Switch Stroke > Curve mode between Elastic (local edits) and Liquid (broader smoothing) depending on how you want adjustments to propagate.
  • Tap on empty canvas to commit the curve when satisfied.
• Clean embedding options
  • Fast embed (no booleans): Lower Brush > Depth > Imbed (negative values) to sink the tube slightly into the surface. Follow with a gentle Deformation > Polish by Features for a seated look without intersections.
  • Production channel (Live Boolean):
    • Duplicate your base as a “Cutter.” Draw a slightly thicker CurveTubeSnap and set its SubTool to Subtractive.
    • Enable Live Boolean to preview the groove. Make Boolean Mesh to commit a clean channel with natural edge breaks.
    • Draw your final wire slightly thinner and snap it into the channel for a protected, manufactured fit.
• Precision and repeatability
  • Use Stroke > Curve Functions > Frame Mesh on polygroups or open edges to auto‑generate curves; then apply CurveTubeSnap for perfectly routed cables along panels.
  • For straight runs, enable Backtrack (Brush > Modifiers) with Spline/Line to lock perfectly linear segments between anchors.
  • Add clamps or connectors with an IMM Curve brush that contains repeated parts; set CurveStep for even spacing along the path.
• Finishing
  • Assign unique Polygroups to wires for fast isolation. If you need lighter geometry, ZRemesher with Keep Groups and Crease to preserve roundness, then add a Subdivision and Polish by Features lightly.
  • Avoid merging wires into DynaMesh with the base until final; keep them as separate SubTools for editability.
• Troubleshooting
  • Floating sections: increase snap strength by using CurveTubeSnap or reduce Draw Size while placing tight curves.
  • Popping while editing: toggle Stroke > Curve > Lock Start/End to keep endpoints fixed.
  • Uneven thickness: ensure Dynamic is off and keep consistent Draw Size; apply a light Deformation > Inflate to normalize.
