LIGHTING CONTINUITY (VGoT HDR dimension) — same scene = same physics of light:
Per-Panel Lighting Specification:
- Every panel MUST explicitly state: key light direction (left/right/top/back), quality (hard/soft), color temperature (warm/cool/neutral)
- If panel 1 has "warm golden side-light from left", ALL subsequent panels in the same scene maintain left-side warm light
- Shadow direction follows light source — never contradictory between adjacent panels
Color Temperature Rules:
- Golden hour: warm (3000-4000K), shadows are long and soft
- Overcast/cloudy: cool neutral (5500-6500K), diffuse shadows
- Night/indoor: blue-shifted ambient + warm practicals (candles, lamps)
- Neon/cyberpunk: mixed cool ambient + saturated colored practicals
Scene Transition Lighting:
- Same scene: lighting MUST be identical across all panels
- Time skip within scene: gradual shift only (sunrise→morning, not noon→midnight)
- Location change: lighting reset allowed, but state it explicitly
Verification Checklist:
- Flag any panel where light direction reverses from its neighbor
- Flag color temperature shifts without scene/time change
- Flag missing light source description (every panel needs one)
Example
Same scene, 3 panels:
- Panel 1: warm key from LEFT, hard, 3500K, long shadows falling right.
- Panel 2: same LEFT warm key, 3500K — subject turns, shadows still fall right. ✓
- Panel 3: key suddenly from RIGHT, 6000K cool, with no time skip → FLAG (light-direction reversal + color-temperature jump).
