| 3 | Mood-driven illumination. Guide player attention. Support art direction. |
| 4 | |
| 5 | ## When to Use |
| 6 | |
| 7 | - Scene look development |
| 8 | - Cinematic renders and portfolio shots |
| 9 | - Horror atmosphere setup |
| 10 | - Game lighting blockout (baked or dynamic) |
| 11 | - HDRI environment setup |
| 12 | |
| 13 | ## Workflow |
| 14 | |
| 15 | ``` |
| 16 | Art Direction → Key Light → Fill/Rim → Accent → Environment |
| 17 | → Volumetrics → Color Grade Prep → Validation Renders |
| 18 | ``` |
| 19 | |
| 20 | ## Three-Point Lighting |
| 21 | |
| 22 | | Light | Purpose | Typical Setup | |
| 23 | |-------|---------|---------------| |
| 24 | | Key | Primary illumination | 45° above, 30° side | |
| 25 | | Fill | Shadow softening | Opposite key, 1/2–1/4 intensity | |
| 26 | | Rim | Subject separation | Behind subject, bright edge | |
| 27 | |
| 28 | Naming: `LGT_Key_Main`, `LGT_Fill_Soft`, `LGT_Rim_Back` |
| 29 | |
| 30 | ## Light Types |
| 31 | |
| 32 | | Type | Use Case | |
| 33 | |------|----------| |
| 34 | | Sun | Outdoor directional | |
| 35 | | Area | Soft studio, windows | |
| 36 | | Spot | Flashlights, stage, horror | |
| 37 | | Point | Bulbs, emissive fill | |
| 38 | |
| 39 | ## Color Temperature |
| 40 | |
| 41 | | Mood | Kelvin | RGB Approx | |
| 42 | |------|--------|------------| |
| 43 | | Candle/warm | 1800K | Orange | |
| 44 | | Tungsten | 3200K | Warm white | |
| 45 | | Daylight | 5500K | Neutral white | |
| 46 | | Overcast | 6500K | Cool white | |
| 47 | | Moonlight | 8000K+ | Blue | |
| 48 | |
| 49 | Horror: mix warm interior tungsten with cold exterior moonlight. |
| 50 | |
| 51 | ## HDRI Workflow |
| 52 | |
| 53 | ``` |
| 54 | 1. Select HDRI matching mood (overcast for horror, clear for hero) |
| 55 | 2. Rotate to place brightest area as key |
| 56 | 3. Adjust strength (0.5–2.0 typical) |
| 57 | 4. Supplement with area lights for subject separation |
| 58 | 5. Hide HDRI in background if using solid color/fog |
| 59 | ``` |
| 60 | |
| 61 | ## Horror Lighting |
| 62 | |
| 63 | See horror-style skill. Key techniques: |
| 64 | - High contrast; deep shadows |
| 65 | - Single source motivation (one visible lamp) |
| 66 | - Flicker via noise modifier on strength |
| 67 | - Volumetric fog for light shafts |
| 68 | - Avoid flat even illumination |
| 69 | |
| 70 | ## Volumetrics |
| 71 | |
| 72 | ``` |
| 73 | World shader → Volume Scatter |
| 74 | Light → Volume contribution enabled |
| 75 | Density: 0.01–0.1 (subtle to heavy fog) |
| 76 | Anisotropy: 0.3–0.8 for visible light shafts |
| 77 | ``` |
| 78 | |
| 79 | ## Game vs Cinematic |
| 80 | |
| 81 | | Aspect | Game | Cinematic | |
| 82 | |--------|------|-----------| |
| 83 | | Light count | Minimal (performance) | Unlimited | |
| 84 | | Baked | Lightmaps common | Path trace | |
| 85 | | Dynamic | Real-time shadows | Ray traced | |
| 86 | | Mood | Gameplay readability | Artistic freedom | |
| 87 | |
| 88 | ## MCP Integration |
| 89 | |
| 90 | 1. Create lights with naming convention via MCP |
| 91 | 2. Set color, intensity, angle via MCP |
| 92 | 3. Configure world HDRI via MCP |
| 93 | 4. Query light count and types |
| 94 | 5. Organize in `COL_Lights` collection |
| 95 | |
| 96 | ## Constraints |
| 97 | |
| 98 | ### MUST DO |
| 99 | - Motivate every light source (visible fixture or logical source) |
| 100 | - Name lights `LGT_[Role]_[Descriptor]` |
| 101 | - Test readability of gameplay-critical areas |
| 102 | - Match lighting to style skill (horror, realistic, etc.) |
| 103 | - Separate lighting collections from geometry |
| 104 | |
| 105 | ### MUST NOT DO |
| 106 | - Flat ambient without direction |
| 107 | - Over-light horror scenes |
| 108 | - Ignore color temperature consistency |
| 109 | - Place lights without purpose |
| 110 | - Skip volumetric consideration for mood scenes |
| 111 | |
| 112 | ## Reference Guide |
| 113 | |
| 114 | | Topic | Reference | Load When | |
| 115 | |-------|-----------|-----------| |
| 116 | | Horror setups | `references/horror-lighting-setups.md` | Horror scenes | |
| 117 | | Cinematic rigs | `references/cinematic-light-rigs.md` | Portfolio renders | |
