# Sculpting (heads and characters, Blender 5.2) Expert sculpting is structure first and surface last: masses blocked with stated planes and corners, proportions locked at low resolution, every stage judged by eye through a long lens, and appeal as the final test, not the mesh numbers. The agent builds blockout and primary forms headless ([`scripts/bx_sculpt.py`](scripts/bx_sculpt.py): smooth-blend `Clay`, plane cuts, numpy brushes) and does client-quality surface work with Blender's real brushes in a live GUI session (`bx_gui`). 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-blender-expert (execution channel, review loop, 5.2 API changes). ## Stance (the expert delta) - **Planes are stated, not found.** Thelen cuts plane borders with Draw Sharp and re-cuts them whenever a face "looks off"; Naydenov simplifies into planes, then smooths; Reinhardt uses Scrape, Trim and Line Project for clean cuts. Executable form: give the plane (point + normal) to `Clay` half-space clips or `plane_cut` / `corner_cut`. A `flatten` or `scrape` dab fits its plane to the ball under it, so it follows the ball. - **The jaw is a block with a gonial corner, the cheekbone a mass with its own lower plane.** Zarins: the gonial angle is the age and sex dial, steep in adult males; the widest face point is the t...
