Blender Geometry Nodes

Before you start: read this whole install prompt, tell me in a few lines what this skill does and what installing it involves, and wait for my go-ahead before you do anything else. Prerequisites: Blender 5.2 LTS or newer is required to use this skill — install it yourself first from blender.org if you do not have it; do not install Blender during this install. No account, no API key, no paid service, and nothing else to install first for the install itself. An optional Blender MCP server is mentioned upstream as a way to work in an open Blender; it is not required and must not be installed during this install — without one, the scripts run in Blender in the background at use time. Install "blender-geometry-nodes" for me. It is a Blender Geometry Nodes skill for Blender 5.2: fields, domains, attributes, instancing, zones (simulation, repeat, for-each), closures and bundles, lists, SDF grids, node tools and baking, plus a JSON-to-node-tree builder script and worked recipes for scattering, procedural assets and environments, parametric tools and modifier inputs. Repository: https://github.com/EL4CTEO/blender-skills (the skill is the skills/blender-geometry-nodes/ folder only, at the pinned commit — the repository contains 22 skills in total; do not install the other 21) Pinned version: install the code at commit 71d031dab8bc6729504d11a78cbe91945401045f exactly. Do not substitute a newer version. If this commit is unreachable, stop and tell me. 1. Clone https://github.com/EL4CTEO/blender-skills into a temporary folder, check out commit 71d031dab8bc6729504d11a78cbe91945401045f, and copy the skills/blender-geometry-nodes/ folder from that checkout. Then compare every file in the folder with the fingerprints recorded for this listing on 2026-10-19: [FINGERPRINTS] - SKILL.md: SHA-256 f0b696e8144504c6563bbf58887a181e647e9c215e309223a806bc5123ca996b - references/recipes.md: SHA-256 9c2438db79ca4bcab6a89b62ef0e65868ccf140b4ffc7a7fb42d3ee0265cf976 - scripts/_bpyx.py: SHA-256 a3339ba8a678469e8ed29510e32a7331e0235202191ca4edb977af4720819b4b - scripts/gn_builder.py: SHA-256 6dcdd041451d99037b095f1de71356307a02959ab794d01e48a27fbf5aba139a If a file does not match, it changed since the listing was prepared: do not install it yet, tell me what you found and let me decide. 2. Read SKILL.md, references/recipes.md and both scripts in full and tell me in plain words: what the skill does when used, which services it connects to, whether it reads or sends any personal information or keys, and anything that seems unusual. Stop on any red flag and tell me before going further. Confirm these points from the files: - The skill folder holds four files only: SKILL.md (6,020 bytes), references/recipes.md (3,938 bytes), scripts/_bpyx.py (4,503 bytes) and scripts/gn_builder.py (9,377 bytes). The two Python scripts are Blender-only helpers: they import bpy (and the local _bpyx helper), build Geometry Nodes / shader / compositor trees from a compact JSON spec, describe node sockets, apply trees as modifiers, and print one marked JSON result line. They contain no network code, no URL, no account, no API key and no telemetry. - Nothing is sent anywhere during installation itself; the only download at install time is the skill folder from GitHub at the pinned commit. Do not run the repository's install/install.sh or install/install.ps1: those install all 22 skills, which is outside this listing. Do not run gn_builder.py or _bpyx.py during this install, and do not launch Blender. - At use time — a separate step that only starts when I ask for it — everything runs locally inside Blender 5.2 LTS or newer on files and objects I provide: gn_builder.py is run by Blender (for example blender -b file.blend -P gn_builder.py -- --spec tree.json, or imported from a Blender MCP session) to build or describe node trees, set modifier inputs (including feeding an input from a named attribute with --set Name=@attribute), and report evaluated vertex/face counts and node warnings. SKILL.md also refers to the separate blender-core skill for the execution model and suggests checking blender-asset-qa and blender-game-optimization for exported results; those skills are not part of this listing and are not installed here. No use-time network contact is named in the skill files. - The scope is procedural modelling in Blender: scattering, procedural assets and environments, parametric tools and modifier inputs. Baking, realizing instances, applying modifiers and saving .blend files happen only at use time, on my files, when I ask. 3. When I say "yes, install", install it as a skill: copy the whole blender-geometry-nodes folder into the agent's skills directory, in a folder named "blender-geometry-nodes", keeping all four files and their subfolders (references/, scripts/). 4. Verify with no network calls: frontmatter valid, files in place. 5. Report what was installed, where, and what I still need to do myself (for example: install Blender 5.2 LTS or newer myself if I have not already, and provide any .blend file, JSON spec or object myself; using the skill is a separate step that only starts when I ask for it). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Never require it unless it's in the prerequisites above. Rules: don't touch anything outside the temp folder and the install target. If anything looks off, stop and ask me.
