ZBrush Tip: Reproject Higher Subdiv to Restore Microdetail

Recover high-frequency detail after reshaping your low subdivision levels by using Tool > Geometry > Reproject Higher Subdiv. This maintains your sculpt’s fidelity without altering topology.

When to use it

• After proportion changes at SDiv 1–2 that softened or destroyed pores, wrinkles, or crisp edges at higher levels.
• Post “Freeze Subdivision Levels” workflows when you edited the base with ZModeler or Deformation tools and need your micro detail back.
• When importing an updated base mesh at SDiv 1 (same vertex order) and you want to realign existing higher-level details.

Core workflow (reproject progressively)

• Go to the lowest subdivision level (Tool > Geometry > Lower Res).
• Mask areas you don’t want adjusted; visibility and masks constrain the reproject.
• Click Reproject Higher Subdiv.
• Step up one subdivision level, evaluate, and click Reproject Higher Subdiv again.
• Repeat per level until you reach the highest SDiv and the original detail is restored.

Best practices

• Store a Morph Target at SDiv 1 before large edits so you can paint back your pre-edit shape with the Morph brush where needed.
• Use polygroups and partial visibility to control which regions reproject—great for preserving new silhouette changes while recovering pores only in selected areas.
• If minor artifacts appear, lightly Smooth (Shift) at a lower SDiv, or use Polish by Features at low intensity.
• Assign a hotkey: Ctrl+Alt+Click the Reproject Higher Subdiv button to bind a custom shortcut and speed up the per-level iteration.

Troubleshooting

• Exploding verts or spikes: Ensure your mesh is manifold and free of double vertices (Tool > Geometry > Modify Topology > WeldPoints as appropriate). Mask trouble zones before reprojecting and clean with the Move or Smooth brushes.
• No effect or button greyed out: Reproject Higher Subdiv requires an unchanged vertex count across subdivision levels. If topology changed, use Freeze Subdivision Levels before edits, or transfer detail using SubTool > Project > Project All between meshes.
• Detail still looks soft: Reproject per level (not just once). Evaluate after each step and add selective masking to protect newly established shapes.
• UVs: Since you’re staying within the same mesh, UVs created at the base level are preserved—verify by toggling Morph UV to confirm island integrity.

Workflow tips that pair well

• Combine with Layers: Keep micro detail on a layer so you can blend intensity after reprojection.
• Use Dam_Standard or ClayBuildup lightly after reprojection to re-accent plane breaks.
• QuickSave and incremental files help you A/B test different reproject passes safely.
