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 | $0.00041 | $0.00905 |
| Opus 5 | $0.00020 | $0.00452 |
| Sonnet 5 | $0.00008 | $0.00181 |
| Haiku 4.5 | $0.00004 | $0.00090 |
Grade A, and why
lighting 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 8d 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.

Lighting Artist
Mood-driven illumination. Guide player attention. Support art direction.
When to Use
- Scene look development
- Cinematic renders and portfolio shots
- Horror atmosphere setup
- Game lighting blockout (baked or dynamic)
- HDRI environment setup
Workflow
Art Direction → Key Light → Fill/Rim → Accent → Environment
→ Volumetrics → Color Grade Prep → Validation Renders
Three-Point Lighting
| Light | Purpose | Typical Setup |
|---|---|---|
| Key | Primary illumination | 45° above, 30° side |
| Fill | Shadow softening | Opposite key, 1/2–1/4 intensity |
| Rim | Subject separation | Behind subject, bright edge |
Naming: LGT_Key_Main, LGT_Fill_Soft, LGT_Rim_Back
Light Types
| Type | Use Case |
|---|---|
| Sun | Outdoor directional |
| Area | Soft studio, windows |
| Spot | Flashlights, stage, horror |
| Point | Bulbs, emissive fill |
Color Temperature
| Mood | Kelvin | RGB Approx |
|---|---|---|
| Candle/warm | 1800K | Orange |
| Tungsten | 3200K | Warm white |
| Daylight | 5500K | Neutral white |
| Overcast | 6500K | Cool white |
| Moonlight | 8000K+ | Blue |
Horror: mix warm interior tungsten with cold exterior moonlight.
HDRI Workflow
1. Select HDRI matching mood (overcast for horror, clear for hero)
2. Rotate to place brightest area as key
3. Adjust strength (0.5–2.0 typical)
4. Supplement with area lights for subject separation
5. Hide HDRI in background if using solid color/fog
Horror Lighting
See horror-style skill. Key techniques:
- High contrast; deep shadows
- Single source motivation (one visible lamp)
- Flicker via noise modifier on strength
- Volumetric fog for light shafts
- Avoid flat even illumination
Volumetrics
World shader → Volume Scatter
Light → Volume contribution enabled
Density: 0.01–0.1 (subtle to heavy fog)
Anisotropy: 0.3–0.8 for visible light shafts
Game vs Cinematic
| Aspect | Game | Cinematic |
|---|---|---|
| Light count | Minimal (performance) | Unlimited |
| Baked | Lightmaps common | Path trace |
| Dynamic | Real-time shadows | Ray traced |
| Mood | Gameplay readability | Artistic freedom |
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.

lighting is a skill published in the GitHub repository arjun988/blender-skills (172 stars, last pushed 1mo ago), licensed MIT. It adds 41 tokens to every session and 905 once invoked, about $0.0002 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.
