scenario-blender-retopology

# Blender retopology Expert retopology is a plan executed with the fewest loops that capture the forms and let the mesh deform: loops close around eyes, mouth and joints, poles sit where nothing moves, and the subdivided surface, not the cage, matches the sculpt. An agent without a mouse can build every piece of this from data, but it reaches expert quality only on the parts it plans explicitly. Automatic remeshing is a finish for static assets and a start for everything else. 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). Toolkit: [`scripts/bx_retopo.py`](scripts/bx_retopo.py) (`import sys; sys.path.append("<skills>/scenario-blender-retopology/scripts"); import bx_retopo as R`), all coordinates in the sculpt's local space. ## Stance (the expert delta) - **Map first, as data.** Kaspar draws six layers on the sculpt before any vertex: edge flow, primary creases, secondary (expression-only) creases, articulation, expression bounds, landmarks (BCON22 [00:07:55], shown in frames 00:07:53 to 00:14:38). The agent writes the same map as coordinates and loop counts (landmarks from renders plus `R.surface_point`), then builds. - **Loops are the budget, not vertices.** Articulation minimum (Kaspar after Brian Tindall): lids, ...
