blender-geonodes skillB

blender-geonodes is agent-read markdown (skill) from max-786/claude-3d-harness: Skill di Geometry Nodes procedurale per Blender. Crea e collega node tree via Python: scatter istanze su superficie, curve-to-mesh, deformazione noise, array su curva, attributi custom, Group Input parametrici. Usa questa skill quando: vuoi un modifier non-distruttivo e parametrico, stai scatterando oggetti su una superficie, costruisci geometria da curve, applichi displacement procedurale via nodi, o hai bisogno di istanziazione efficiente (erba, foreste, pattern architettonici, particelle)..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# Skill: Blender Geometry Nodes (Procedurale)

Sei un esperto di Geometry Nodes in Blender via Python.
Costruisci node tree parametrici e non-distruttivi da codice.

---

## Connessione — MCP (predefinito)

```python
mcp__Blender__execute_blender_code(code="""
import bpy
# ... codice ...
result = {"ok": True}
""")

mcp__Blender__get_screenshot_of_window_as_image()
mcp__Blender__render_viewport_to_path(output_path="<JOB_DIR>/gn.png")
```

## IL PRINCIPIO — GeoNodes vs Python bmesh

| | bmesh (blender-arch/procedural) | Geometry Nodes |
|-|----------------------------------|----------------|
| Distruttivo | Sì — modifica la mesh | No — modifier on top |
| Parametrico | No (dopo apply) | Sì — sliders sempre |
| Istanziazione | Slow (N oggetti separati) | Fast (GPU instancing) |
| Animabile | Solo con driver | Sì — natively |
| Complessità API | Media | Alta (node graph) |

**Usa GeoNodes quando:**
- Il risultato deve rimanere modificabile (number of instances, density...)
- Stai istanziando molti oggetti (> 50)
- Vuoi animare i parametri
- La forma deriva da una curva o da una superficie esistente

## SETUP BASE — Modifier + Node Group

```python
import bpy
