Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00184 | $0.05948 |
| Opus 5 | $0.00092 | $0.02974 |
| Sonnet 5 | $0.00037 | $0.01190 |
| Haiku 4.5 | $0.00018 | $0.00595 |
Grade A, and why
blender-materials 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 9d 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 — 503 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Blender Materials
Apply physically-based materials to objects. Use only Principled BSDF — it's the only shader that exports cleanly to glTF and matches what other DCC tools expect.
The metallic switch — never an in-between
The single most-important rule: Metallic is a switch, not a slider. Set it to 0.0 (dielectric: plastic, wood, glass, skin) or 1.0 (metal: steel, gold, copper). Values between 0.2 and 0.8 are almost always wrong; they produce energy-non-conservative renders that look "plasticky."
Exception: dark mirror lenses (sunglasses) use ~0.8 to combine strong reflection with slight tint — that's a stylistic choice, not strict PBR.
Decision tree
What is it made of?
├── Raw metal (steel, gold, copper, etc.)
│ → Metallic=1.0, Base Color = F0 reflectance from physicallybased.info
│ → Roughness controls polish (0.05 mirror → 0.4 brushed → 0.7+ weathered)
│
├── Glass / clear / refractive
│ → Metallic=0, Transmission=1.0, IOR=1.5 (glass), Roughness=0.0
│ → Add Volume Absorption for thick tinted glass
│
├── Plastic / wood / stone (dielectric, opaque)
│ → Metallic=0, IOR=1.45 (plastic) or 1.5 (most others)
│ → Roughness per finish (0.15 glossy / 0.6 matte)
│ → Coat Weight 0.5+ for varnished/lacquered surfaces
│
├── Skin / wax / marble (subsurface scattering)
│ → Metallic=0, Subsurface Weight=1.0
│ → Subsurface Radius RGB tuned per material (skin: red scatters deepest)
│
├── Cloth / fabric (sheen)
│ → Metallic=0, Sheen Weight 0.2-0.5
│ → Roughness 0.6+, Sheen Roughness 0.5
│
└── Mirror / chrome (special metal)
→ Metallic=1.0, Roughness=0.02-0.05, near-white base
Reference-look handoff
If the goal is to match an original/reference image rather than make a generally attractive render, chain-load reference-look-calibration. It owns measurement of hue/saturation/value, object extent, glow/aura color, and before/after look metrics. This skill should then apply the requested material/lighting/render changes within that calibrated target.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

blender-materials is a skill published in the GitHub repository RobLe3/cc-blender-skill (53 stars, last pushed 4mo ago), licensed MIT. It adds 184 tokens to every session and 5,948 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
