Key Benefits

  • Photorealistic lighting from real-world reference without manual tweaking
  • Frame-by-frame transition data maps directly to Lumen engine parameters
  • Consistent lighting across scenes using measured Kelvin and intensity values
  • 80% faster than manual lighting artist iteration

16-Agent Analysis Pipeline

Step-by-Step Workflow

1

Capture Reference

Film or find reference footage of the real-world lighting you want to recreate — walking from indoor to outdoor, golden hour transitions, neon-lit streets.

2

Extract Key Frames

Pull representative frames at each lighting transition point.

3

Run Through Grain

Analyze each frame to extract color temperature (Kelvin), light direction vectors, intensity ratios, shadow density, and atmospheric scatter.

4

Map to Engine

Convert Grain's structured output to engine-native parameters — Unreal Lumen settings, Blender light objects, or Houdini Mantra attributes.

5

Validate

Compare rendered output against original reference using Grain's comparison mode.
