# Realistic characters and creatures (ZBrush 2026) Expert level here means every form has a cause (skull, mass, tension, compression) before any pore exists, and every detail pass is reversible, regional and judged in renders from several views and lights. The agent works the way Kingslien and Costa do: find the upstream cause, fix it at the lowest level that holds it, and keep detail on layers or behind a stored morph target. 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_character.py`](scripts/zb_character.py) (stroke plans, ZBrush-side wrappers via `zb_character.call(...)`, OBJ, alpha and render checks) on the lead's toolkit. ## Stance (the expert delta) - **Cause before form, in planes.** Kingslien: cranial versus facial mass, then the Bridgeman masses (forehead box, flat cheek, maxilla cylinder, triangular jaw), then features sculpted through the forms around them (nostril through the alar facial juncture, eye through the nasojugal groove). "Almost everything right or wrong in this face is right or wrong back in the beginning." A region touched twice means replan (`MoveBudget`). His single separating lines suit synthesized strokes. - **Detail is worthless on a weak base.** Costa: judge prima...
