reference-look-calibration
Calibrate Blender materials, lighting, camera crop, emission/glow, color management, and aura/HUD styling against supplied original/reference images using measurable color, brightness, saturation, bbox, and mask statistics. Use when a product must match the lighting/look of a source image or when audits say the product is too bright, desaturated, wrong hue, wrong glow, or wrong silhouette extent.

What does this agent skill do?
Reference Look Calibration
This skill handles the final visual match after geometry and UVs are locked. It must not compensate for wrong shape, wrong UVs, or wrong camera framing.
Inputs
- accepted geometry / UV fit reports;
- reference/original image(s);
- product preview render(s);
- optional mask overlays and multiview fit reports.
Metrics
Use scripts/look_fit_report.py to compare:
- object/bright-mask IoU and bbox extent;
- configured hue-band mask IoU for glow/accent assets;
- mean/std HSV and BGR under object mask;
- brightness p95 / mean;
- saturation mean;
- hue drift.
Calibration order
- Camera crop / orthographic scale — object extent must match before color tuning.
- World/background darkness.
- Base material hue/value/saturation.
- Emission strength and glow color.
- Aura/HUD ring color and thickness.
- Color management / exposure / gamma.
- Final render overlay and metrics.
Hard rules
- Do not tune lighting before geometry/UV fit gates pass.
- Do not change accent/glow hue away from the source reference unless the user explicitly asks.
- Do not hide mismatched geometry with bloom, fog, or overexposure.
- Write look metrics before and after calibration.
Handoff
Consumes validation/multiview_fit_report*.json and product previews. Produces validation/look_fit_report.json, look overlays, and updated material/light/render settings.
