blender-python

blender-python is a skill for Claude Code from GoogilyBoogily/googilyboogily-claude-power-tools. It costs 240 tokens per session (3,163 once invoked), scanned A, original, MIT.

A skill for controlling Blender, a 3D creation program, through Python. Blender's Python API can create and change scenes, objects, materials, meshes, rigs, animations, and renders.

In plain words
What is it for?
Use it to automate 3D modeling, geometry editing, materials, animation, rigging, rendering, Blender add-ons, or geometry-node and shader-node tasks.
Why use it?
It lets repeatable scripts handle Blender work and supports both the graphical application and background rendering. It also accounts for Blender's context-sensitive operations, which can otherwise fail when run in the wrong mode.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

blender-python scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 195 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Blender Python API

Drive Blender via its embedded Python interpreter (bpy). Covers GUI scripting, headless --background automation, addon authoring, the bpy-as-pip-module path, and live MCP control. Reference files in references/ deepen each area — load on demand, not all at once.

Operating Principles

  1. Work through the data API, not operators, when possible. bpy.ops.* calls depend on context (active area, mode, selection). They fail with RuntimeError: poll() failed, context is incorrect from scripts. Direct manipulation through bpy.data.objects["Cube"].location.z = 1.0 is faster, deterministic, and works headless. Use operators only when the data API has no equivalent (e.g., complex modeling tools, file I/O wrappers).

  2. Identify the target environment first. Three execution modes — pick one before writing code:

    • Inside Blender GUI — Text Editor / Python Console. Full context, full UI redraws.
    • Headless --background — blender file.blend -b -P script.py. No UI, no event loop. Modal operators don't run, redraws don't happen, viewport context is empty.
    • bpy as Python module — pip install bpy, then import bpy from any script. Behaves like --background --factory-startup. Same headless caveats.

  3. Match the Blender version. API breaks across major versions. Blender 4.x changed animation slots/layers, geometry nodes interfaces, and the OBJ/STL operators (now bpy.ops.wm.obj_export / obj_import, not export_scene.obj). When the user states a version, match it; otherwise default to Blender 4.5 LTS and confirm.

  4. Read the source for poll failures. When an operator refuses to run, check bpy.ops.foo.bar.poll() first. If False, the fix is usually a bpy.context.temp_override(...) block or switching to data-API equivalents. See references/gotchas.md.

  5. Don't auto-overwrite the user's .blend file. Always confirm before bpy.ops.wm.save_mainfile() against the original path. Prefer save_as_mainfile(filepath=..., copy=True).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
