ZBrush retopology and export (pipeline sculptor)

Expert level means the sculpt leaves ZBrush as a light, clean exchange mesh at its lowest level, detail kept on a rebuilt subdivision stack or in maps, at real size, every file proved by parsing it. Most of it is deterministic palette work an agent does well; click-by-click topology, modifier clicks and a few dialogs stay with a human or computer-use agent. If a sibling skill named here is missing from your available skills, ask the user to install it (npx skills add scenario-labs/skills --skill <name>); unattended, proceed from tool schemas and flag the gap.

REQUIRED BACKGROUND: scenario-zbrush-expert (bridge, stroke engine, review loop, 2026 traps).

Toolkit: scripts/zb_retopology_export.py (rx) on top of the lead's zb_ops, zb_audit and zb_launch: rx.zcall("func", ...) inside ZBrush, audits on the agent side. Every projection pass is the lead's safe zb_ops.project_all (versioned checkpoint, nets, gate). Not yet run in ZBrush (88 offline tests pass; live tests in references/procedures.md).
