blender-geonodes SKILL.md skillB
blender-geonodes from max-786/claude-3d-harness is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add max-786/claude-3d-harness/blender-geonodes@git:20260921.8093f5dPins git:20260921.8093f5d in mdr.lock. Pin the fingerprint instead.

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).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file 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

How to install
mdr add max-786/claude-3d-harness/blender-geonodes@sha256:19f701f7c1a36a9dThe line at the top of this page pins the label git:20260921.8093f5d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
