HDRI Workflow

HDRI工作流

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

恐怖风格灯光

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
参见恐怖风格技能。核心技巧：
  • 高对比度；深阴影
  • 单一光源逻辑（仅一盏可见灯具）
  • 通过强度的噪波修改器实现闪烁效果
  • 用体积雾制造光束效果
  • 避免平坦均匀的照明

Volumetrics

体积光

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

MCP集成

  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
  1. 通过MCP按照命名规范创建灯光
  2. 通过MCP设置颜色、强度、角度
  3. 通过MCP配置环境HDRI
  4. 查询灯光数量与类型
  5. 整理至
    COL_Lights
    集合中

Constraints

约束规范

MUST DO

必须遵守

  • 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
  • 每个光源都要有合理依据（可见灯具或逻辑光源）
  • 灯光命名格式为
    LGT_[Role]_[Descriptor]
  • 测试游戏关键区域的可读性
  • 灯光风格需匹配对应风格技能（恐怖、写实等）
  • 灯光集合需与几何体集合分离

MUST NOT DO

禁止操作

  • Flat ambient without direction
  • Over-light horror scenes
  • Ignore color temperature consistency
  • Place lights without purpose
  • Skip volumetric consideration for mood scenes
  • 无方向的平坦环境光
  • 恐怖场景布光过亮
  • 忽略色温一致性
  • 无目的地放置灯光
  • 氛围场景不考虑体积光效果
