reference-look-calibrationlisted

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.

# 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 1. Camera crop / orthographic scale — object extent must match before color tuning. 2. World/background darkness. 3. Base material hue/value/saturation. 4. Emission strength and glow color. 5. Aura/HUD ring color and thickness. 6. Color management / exposure / gamma. 7. 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.
