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.

Skill instructions

Rendered from the published SKILL.md, 48 lines.

MCP backend

Use when: Reference-based look-dev, lighting/material/color calibration, original-image visual matching, glow/aura/HUD matching, HSV/brightness/mask fit reports, final look pass after geometry and UV are locked.

Before the first Blender call, read ../text-to-blender/references/mcp-backends.md. Prefer official MCP for shared capabilities; preserve the selected backend for the whole task. Tool names in recipes are client/legacy examples: map them through that reference and its agent-host guide.

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.

reference-analysis-validator
Measure and validate supplied reference images, wireframes, texture atlases, and Blender renders before declaring a reconstruction 1:1. Use when an asset must match a template, when visual feedback says the output is off, when part counts must be exact, or before exporting a brand mascot/logo reconstruction. Pairs with reference-to-3d, contour-to-mesh, orthographic-registration, atlas-uv-fitting, and Blender MCP.

reference-to-3d
Reconstruct Blender models from supplied reference sheets, branding templates, texture atlases, orthographic front/side/back/top views, or mascot/logo art where visual fidelity to the source is more important than a plausible generated object. Use when the user says the model must match a template, wireframe, texture pack, character sheet, mascot sheet, or brand asset exactly; also use after feedback like "does not look like the reference", "fit the texture 1:1", "wrong number of visible parts", or "compare against the template". Requires Blender MCP plus local Python with Pillow/OpenCV/numpy; pairs with blender-uv-texturing, wireframe-to-3d, blender-modeling, blender-materials, and blender-export.

critique-color
Critique a rendered screen's colour — contrast ratios, palette coherence, and semantic meaning. Use when reviewing one screen. For a product-wide WCAG audit use `accessibility-audit` (design-systems); for building the palette use `color-system` (ui-design).

threejs-materials-lighting
Light and shade a three.js scene: choose materials (MeshStandardMaterial PBR vs unlit MeshBasicMaterial), add ambient/hemisphere/directional/point/spot lights, turn on shadow maps, and use an environment map (IBL) for realistic reflections. Use when a three.js model looks black, flat, or wrong — when the user mentions three.js materials, MeshStandardMaterial, lights, shadows, envMap, or PBR. For renderer/loop setup use threejs-scene-setup; for loading models use threejs-gltf-loading.

taste-distillation
Measure a set of reference videos into a reusable style pack - colour grade as a 3D LUT, cut rhythm as a shot-length distribution, hero stills, screen-blend overlay plates, and a text spec for a generative model. Use when the user wants to capture the look of reference footage, build a repeatable look, mint assets from references, or reproduce someone's grade and pacing.
