scenario-zbrush-sculpting

# ZBrush sculpting (core forms, scripted strokes) Expert sculpting goes big to small with gates: light meshes raised in resolution only when the forms ask, clay built across the form in thin low-intensity layers, sharpness last and never on weak shapes. An agent has no pen: it uses exact operations first (primitives, ZSpheres, DynaMesh, masks plus Deformation sliders), then strokes planned from model-space forms, aimed through the view, measured in volume and reviewed after every pass ([`scripts/zb_sculpt.py`](scripts/zb_sculpt.py)). 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). ## Stance (the expert delta) - **Pressure is the hidden setting.** Henning Sanden blocks at ClayBuildup Z 20 with "maybe 30%" of his pen pressure (0PaYUUvgwYM 00:04:58); a scripted stroke has constant pressure. Start clay at Z 6, refine at 2 to 1, calibrate once per session (`zs.run_calibration`), and dial a whole pass after review: a partial Morph value softens it, a negative one exaggerates it (Drust, B_wKwXwjcZs 00:05:20); layer intensity does the same on levels. - **Clay across the form, lines along it.** Henning: across puts a peak in the center that fades to the edges; along is "drawing the shape" (0PaYUUvgwYM 00:02:13, 00:30:39).
