ZBrush Tip: Precision panel lines with ZBrush Clipping brushes

Quick, clean panel separations on hard-surface models are easy with ZBrush’s Clipping brushes—when you set them up right.

Why use Clipping for panel lines

• Creates razor-straight breaks and planar transitions ideal for manufactured forms.
• Fast, repeatable results without switching out of sculpting context.
• Works beautifully alongside HPolish, Trim, and Panel Loops for final refinement.

Setup for reliable results

• Duplicate your SubTool and store a Morph Target for easy comparisons.
• Ensure even, sufficiently dense topology (ZRemesher + Subdivide, or a high-res DynaMesh).
• On thin shells, enable BackfaceMask (Brush > Auto Masking) to protect the far side.

Key brush choice and settings

• Select ClipCurve, ClipRect, or ClipCircle (B then C to filter the brush menu).
• For narrow, controlled lines, set Brush > Modifiers > Clip Brush Modifiers > BrushRadius to a low value (e.g., 1–5). This confines the clip to a thin band rather than the whole plane.
• Keep ZIntensity at 100 for a decisive clip; adjust only if you prefer gentler transitions.

Drawing precise panel lines with ClipCurve

• Drag the ClipCurve across the surface; the white side of the gradient is preserved, the opposite is clipped toward the curve’s plane.
• Hold Alt and tap to insert corner points for sharp changes of direction; Shift to constrain angles.
• Use two parallel passes: first define one edge plane, then a second, slightly offset pass to establish the opposite edge. The gap reads as your panel line.

Refining the groove and edges

• Run HPolish or Polish by Features lightly to unify the planar surfaces without rounding the break.
• Accentuate the seam with Dam_Standard + LazyMouse for a crisp, controllable recess along the clipped break.
• For a subtle bevel, brush a quick Pinch pass along the seam, then soften with low-intensity Smooth.

Curved and geometric panels

• ClipCircle: create concentric or circular panel lines; scale by re-dragging before release.
• ClipRect: block in rectangular or multi-segment access panels quickly.
• Combine multiple ClipCurve strokes to build complex panel networks with consistent tension and alignment.

Avoiding artifacts

• Clipping collapses points to a plane—use dense, even quads to prevent folding or shading glitches.
• If artifacts appear, lightly Polish by Features, or ZRemesh and Project All from your pre-clip duplicate.
• Avoid clipping across open borders; close holes or isolate regions first.

Pro tip: From clip to panel geometry

• After clipping, use Mask by Cavity to capture the ridge/valley, inflate slightly negative, and polish for a convincing manufactured seam.
• Alternatively, isolate faces by angle (PolyGroups > Group by Normals), then use Panel Loops (low Elevation, small Bevel) for true inset panels with thickness.
