ZBrush Tip: Crease-First ZRemesh for Production-Ready Edge Loops

Preserve your hard edges and panel lines when retopologizing: crease first, then ZRemesh. This workflow yields cleaner, production-friendly edge loops with fewer cleanup passes.

• Identify edges to protect
  • Hard-surface seams, bevel borders, and panel gaps
  • Facial rings: eyelids, mouth corners, nostril loops
  • Silhouette-defining ridges on armor, props, and vehicles
• Create reliable boundaries
  • Polygroups help ZRemesher understand where loops should run. Try Tool > Polygroup > Group by Normals for fast grouping of hard breaks.
  • Refine with Tool > Polygroup > Group Loops to add supporting polygroup borders where you expect loops.
• Crease the right edges
  • Geometry > Crease > Crease PG to crease along polygroup borders in one click.
  • Use Geometry > Crease > Crease by Angle to auto-crease sharp corners (tune the Angle slider for precision).
  • Manually crease with ZModeler: hover an edge > Spacebar > Edge Actions > Crease for surgical control.
  • Optional: set Geometry > Crease > Crease Level to define how long a crease holds when subdividing later.
• Configure ZRemesher to respect your cues
  • Tool > Geometry > ZRemesher:
    • Enable KeepGroups to preserve polygroup borders (pairs well with Crease PG).
    • Enable DetectEdges to prioritize sharp transitions and creased lines.
    • Lower AdaptiveSize (5–20) for more even, loop-friendly distribution; raise slightly if shape fidelity suffers.
    • Set a realistic Target Polygons Count; start modest, iterate upward only as needed.
• Iterate, then uncrease as needed
  • Run ZRemesher and evaluate: loops should hug creased boundaries and polygroup seams.
  • Where extra definition is needed, add Group Loops, crease again, and re-run.
  • After you have the loops you want, use Geometry > Crease > Uncrease All or selectively uncrease to restore natural smoothing before subdivision.
• Finishing touches
  • If you remeshed from a high-res sculpt, Project All to transfer surface detail onto the cleaner topology.
  • Use HPolish/TrimDynamic to refine planes without breaking newly preserved loops.
  • For mechanical edges, a light bevel after remesh reads better than razor-sharp creases at render time.

Troubleshooting:

• Wobbly loops across a seam: reduce AdaptiveSize and ensure the seam is both polygrouped and creased.
• Spiraling or T-junction artifacts: add supporting Group Loops to clarify pathing, then re-crease.
• Over-creasing causes clutter: crease only the edges that must anchor topology.

Pro tip: For concept speed, crease broad panel borders first to lock macro loops, ZRemesh at a low target, then add secondary creases for finer loops and remesh again. This staged approach minimizes cleanup.
