What it does

Lighting is an agent skill from arjun988/blender-skills. Cinematic and game lighting in Blender including three-point lighting, HDRI, horror lighting, volumetrics, rim lighting, and mood-driven illumination. Use for look development and scene atmosphere via MCP.

Its SKILL.md is about 920 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/cinematic-light-rigs.md` and `references/horror-lighting-setups.md`).

It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol and Blender. The repository describes itself as: 94 specialist Blender skills for Cursor, Claude Code, Kiro & Codex - MCP-powered production pipeline from blockout to engine export. The licence is MIT.

When your agent uses it

  • Look development and scene atmosphere via MCP
  • Tasks that involve MCP servers

Example prompts

  • “/lighting”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Create lights with naming convention via MCP
  2. Set color, intensity, angle via MCP
  3. Configure world HDRI via MCP
  4. Query light count and types
  5. Organize in COL_Lights collection

What it can do on your machine

Read from SKILL.md and the folder at commit 8f778d2. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Lighting loads about 922 tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 54 tokens; SKILL.md has 286 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~54
When it runs · the whole SKILL.md, loaded when a task matches
~922
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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

LightPurposeTypical Setup
KeyPrimary illumination45° above, 30° side
FillShadow softeningOpposite key, 1/2–1/4 intensity
RimSubject separationBehind subject, bright edge

Naming: LGT_Key_Main, LGT_Fill_Soft, LGT_Rim_Back

Light Types

TypeUse Case
SunOutdoor directional
AreaSoft studio, windows
SpotFlashlights, stage, horror
PointBulbs, emissive fill

Color Temperature

MoodKelvinRGB Approx
Candle/warm1800KOrange
Tungsten3200KWarm white
Daylight5500KNeutral white
Overcast6500KCool white
Moonlight8000K+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

MCP Integration

  1. Create lights with naming convention via MCP
  2. Set color, intensity, angle via MCP
  3. Configure world HDRI via MCP
  4. Query light count and types
  5. Organize in COL_Lights collection

Constraints

MUST DO
  • Motivate every light source (visible fixture or logical source)
  • Name lights LGT_[Role]_[Descriptor]
  • Test readability of gameplay-critical areas
  • Match lighting to style skill (horror, realistic, etc.)
  • Separate lighting collections from geometry
MUST NOT DO
  • Flat ambient without direction
  • Over-light horror scenes
  • Ignore color temperature consistency
  • Place lights without purpose
  • Skip volumetric consideration for mood scenes

Run `npx skills add arjun988/blender-skills --skill lighting -a codex`. Or copy the skill folder (.claude/skills/lighting in arjun988/blender-skills) into .agents/skills/lighting in your project. Codex loads it when a task matches its description.

Can I use Lighting in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add arjun988/blender-skills --skill lighting -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/lighting, .gemini/skills/lighting, .github/skills/lighting and .opencode/skills/lighting in your project.

What does Lighting need to run?

SKILL.md names no scripts, command-line tools or credentials: Lighting is instructions for the agent only.

Does Lighting access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Lighting safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Lighting use?

Lighting is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Lighting use?

About 922 tokens (SKILL.md is roughly 3.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 537 tokens, read only when the agent opens those files.
