Use **only Principled BSDF** — it's the only shader that exports cleanly to glTF and matches what other DCC tools expect.\n\n## The metallic switch — never an in-between\n\nThe single most-important rule: **Metallic is a switch, not a slider.** Set it to `0.0` (dielectric: plastic, wood, glass, skin) or `1.0` (metal: steel, gold, copper). Values between 0.2 and 0.8 are almost always wrong; they produce energy-non-conservative renders that look \"plasticky.\"\n\nException: dark mirror lenses (sunglasses) use ~0.8 to combine strong reflection with slight tint — that's a stylistic choice, not strict PBR.\n\n## Decision tree\n\n```\nWhat is it made of?\n├── Raw metal (steel, gold, copper, etc.)\n│   → Metallic=1.0, Base Color = F0 reflectance from physicallybased.info\n│   → Roughness controls polish (0.05 mirror → 0.4 brushed → 0.7+ weathered)\n│\n├── Glass / clear / refractive\n│   → Metallic=0, Transmission=1.0, IOR=1.5 (glass), Roughness=0.0\n│   → Add Volume Absorption for thick tinted glass\n│\n├── Plastic / wood / stone (dielectric, opaque)\n│   → Metallic=0, IOR=1.45 (plastic) or 1.5 (most others)\n│   → Roughness per finish (0.15 glossy / 0.6 matte)\n│   → Coat Weight 0.5+ for varnished/lacquered surfaces\n│\n├── Skin / wax / marble (subsurface scattering)\n│   → Metallic=0, Subsurface Weight=1.0\n│   → Subsurface Radius RGB tuned per material (skin: red scatters deepest)\n│\n├── Cloth / fabric (sheen)\n│   → Metallic=0, Sheen Weight 0.2-0.5\n│   → Roughness 0.6+, Sheen Roughness 0.5\n│\n└── Mirror / chrome (special metal)\n    → Metallic=1.0, Roughness=0.02-0.05, near-white base\n```\n\n## Reference-look handoff\n\nIf the goal is to match an original/reference image rather than make a generally attractive render, chain-load `reference-look-calibration`. It owns measurement of hue/saturation/value, object extent, glow/aura color, and before/after look metrics. This skill should then apply the requested material/lighting/render changes within that calibrated target.\n\n\n## Recipes (the 12 to know)\n\nEach recipe creates the material and assigns it to a target object. Replace `'GEO-target'` with your actual object name.\n\n### `set_input` helper — required for some Blender 5.x BSDF inputs\n\nIn Blender 5.x's Principled BSDF v2, **two inputs are flagged `enabled=False`** in the data API: `Weight` and `Subsurface IOR`. These are reachable by **iteration or index** but **not by string-key lookup** — `bsdf.inputs['Subsurface IOR']` raises `KeyError` even though the input exists and its value is respected at render time. This is a Blender 5.x quirk surfaced during v0.4.0 → v0.5.0 validation.\n\nUse this helper whenever a recipe sets an input that might be in the disabled-but-functional state. It works on every input (enabled or not) and is forward-compatible if more inputs become disabled in future Blender versions:\n\n```python\ndef set_input(node, name, value):\n    \"\"\"Set a node input by name. Works on inputs with enabled=False\n    that fail string-key lookup (e.g. 'Subsurface IOR' on Blender 5.x).\n    \"\"\"\n    for inp in node.inputs:\n        if inp.name == name:\n            inp.default_value = value\n            return True\n    return False\n```\n\nFor inputs that are reliably enabled (Base Color, Metallic, Roughness, IOR, Transmission Weight, Sheen Weight, etc.), direct string-key assignment still works fine — the helper is only required where an input is conditionally disabled. **Recipe 9 (Skin) uses it** because `Subsurface IOR` is one of the affected inputs.\n\n### Recipe 1 — Brushed steel\n```python\nimport bpy\n\nmat = bpy.data.materials.new('MAT-steel_brushed')\nmat.use_nodes = True\nbsdf = mat.node_tree.nodes['Principled BSDF']\nbsdf.inputs['Base Color'].default_value = (0.56, 0.57, 0.58, 1.0)\nbsdf.inputs['Metallic'].default_value = 1.0\nbsdf.inputs['Roughness'].default_value = 0.25\n\nobj = bpy.data.objects['GEO-target']\nif obj.data.materials:\n    obj.data.materials[0] = mat\nelse:\n    obj.data.materials.append(mat)\nprint(f\"material:MAT-steel_brushed→{obj.name}\")\n```\n\n### Recipe 2 — Polished gold\n```python\nimport bpy\nmat = bpy.data.materials.new('MAT-gold_polished')\nmat.use_nodes = True\nbsdf = mat.node_tree.nodes['Principled BSDF']\nbsdf.inputs['Base Color'].default_value = (1.022, 0.782, 0.344, 1.0)\nbsdf.inputs['Metallic'].default_value = 1.0\nbsdf.inputs['Roughness'].default_value = 0.05\nbpy.data.objects['GEO-target'].data.materials.append(mat)\nprint('material:gold_polished')\n```\n\n### Recipe 3 — Polished copper\n```python\nimport bpy\nmat = bpy.data.materials.new('MAT-copper_polished')\nmat.use_nodes = True\nbsdf = mat.node_tree.nodes['Principled BSDF']\nbsdf.inputs['Base Color'].default_value = (0.926, 0.721, 0.504, 1.0)\nbsdf.inputs['Metallic'].default_value = 1.0\nbsdf.inputs['Roughness'].default_value = 0.05\nbpy.data.objects['GEO-target'].data.materials.append(mat)\nprint('material:copper_polished')\n```\n\n### Recipe 4 — Mirror chrome\n```python\nimport bpy\nmat = bpy.data.materials.new('MAT-chrome')\nmat.use_nodes = True\nbsdf = mat.node_tree.nodes['Principled BSDF']\nbsdf.inputs['Base Color'].default_value = (0.55, 0.56, 0.55, 1.0)\nbsdf.inputs['Metallic'].default_value = 1.0\nbsdf.inputs['Roughness'].default_value = 0.02\nbpy.data.objects['GEO-target'].data.materials.append(mat)\nprint('material:chrome')\n```\n\n### Recipe 5 — Clear glass\n```python\nimport bpy\nmat = bpy.data.materials.new('MAT-glass_clear')\nmat.use_nodes = True\nbsdf = mat.node_tree.nodes['Principled BSDF']\nbsdf.inputs['Base Color'].default_value = (1.0, 1.0, 1.0, 1.0)\nbsdf.inputs['Metallic'].default_value = 0.0\nbsdf.inputs['Roughness'].default_value = 0.0\nbsdf.inputs['Transmission Weight'].default_value = 1.0\nbsdf.inputs['IOR'].default_value = 1.5\nbpy.data.objects['GEO-target'].data.materials.append(mat)\nprint('material:glass_clear')\n```\n\n### Recipe 6 — Frosted glass\n```python\nimport bpy\nmat = bpy.data.materials.new('MAT-glass_frosted')\nmat.use_nodes = True\nbsdf = mat.node_tree.nodes['Principled BSDF']\nbsdf.inputs['Base Color'].default_value = (1.0, 1.0, 1.0, 1.0)\nbsdf.inputs['Transmission Weight'].default_value = 1.0\nbsdf.inputs['IOR'].default_value = 1.5\nbsdf.inputs['Roughness'].default_value = 0.3\nbpy.data.objects['GEO-target'].data.materials.append(mat)\nprint('material:glass_frosted')\n```\n\n### Recipe 6b — Coloured glass (wine bottle, tinted vials, decorative glass)\n\nUsing only `Base Color` to tint Principled BSDF makes coloured glass look **flat or metallic**. Real coloured glass has *volume absorption*: light passing through gets tinted by the distance it travels, so thick parts look darker and thin parts look lighter. This is the depth-based richness that makes glass read as glass.\n\nPattern: keep the surface near-white with slight roughness, attach a `Volume Absorption` shader to the Material Output's `Volume` input.\n\n```python\nimport bpy\n\ndef set_input(node, name, value):\n    for inp in node.inputs:\n        if inp.name == name:\n            inp.default_value = value\n            return True\n    return False\n\nmat = bpy.data.materials.new('MAT-glass_wine')\nmat.use_nodes = True\nnodes = mat.node_tree.nodes\nlinks = mat.node_tree.links\nbsdf = nodes['Principled BSDF']\noutput = nodes['Material Output']\n\n# Surface: near-white with tiny roughness (breaks mirror-finish look)\nset_input(bsdf, 'Base Color', (0.85, 0.95, 0.85, 1.0))   # near-white\nset_input(bsdf, 'Metallic', 0.0)\nset_input(bsdf, 'Roughness', 0.025)                       # critical: not 0.0; that looks metallic\nset_input(bsdf, 'Transmission Weight', 1.0)\nset_input(bsdf, 'IOR', 1.52)                              # bottle glass\n\n# Volume Absorption — depth-based tint\nvolume = nodes.new('ShaderNodeVolumeAbsorption')\nset_input(volume, 'Color', (0.10, 0.45, 0.18, 1.0))       # saturated wine-bottle green\nset_input(volume, 'Density', 30.0)                         # higher = more colour over short distance\n\nlinks.new(volume.outputs['Volume'], output.inputs['Volume'])\n\nbpy.data.objects['GEO-target'].data.materials.append(mat)\nprint('material:glass_wine_volume_absorption')\n```\n\n**Tuning Density**: 0–10 = very subtle tint (clear bottle); 20–40 = clear bottle-green or amber; 60–100+ = nearly opaque (cobalt-blue medicine bottle).\n\n**Tuning Color**: invert intuition — the volume Color is what gets *removed* from passing light, so for \"wine green\" use saturated green; for \"amber\" use saturated yellow-orange.\n\n**Other coloured-glass examples** (density values updated v0.9.0 after subject-class lighting fix):\n\n| Name | Volume Color | Density | Surface tint |\n|------|-------------|---------|---------------|\n| Wine bottle (deep green) | (0.05, 0.32, 0.10) | 80 | near-white |\n| Pale tinted (clear vial) | (0.10, 0.45, 0.18) | 15 | near-white |\n| Champagne / pale gold | (0.85, 0.65, 0.30) | 25 | near-white |\n| Cobalt blue (medicine bottle) | (0.10, 0.20, 0.85) | 80 | near-white |\n| Amber / brown beer bottle | (0.80, 0.40, 0.10) | 70 | near-white |\n| Ruby red | (0.85, 0.10, 0.15) | 100 | near-white |\n\n**Density tuning rule of thumb under neutral/glass-class lighting**:\n- Density 5–15 = subtle hint of colour (clear + tinted)\n- Density 30–50 = medium tint visible at thin sections\n- **Density 60–100 = proper wine/beer/cobalt bottle look** (recommended for hero shots)\n- Density 100+ = nearly opaque (artistic / decorative)\n\nIf under standard 4:1:2 metal-class lighting the volume tint washes out (v0.7.0 issue), don't crank density to compensate — switch to `subject_class='glass'` lighting in `blender-lighting` Recipe 0a, which uses softer rim that preserves the volume colour.\n\n**Critical**: Cycles `transmission_bounces` must be ≥ 16 (default 12) for thick or layered colour glass; otherwise rays terminate and the glass renders black on the inside.\n\n```python\nscene.cycles.transmission_bounces = 24\n```\n\n**Pitfall**: don't set `Base Color` to the tint colour AND attach a Volume — you get double-tinting that looks wrong. Surface near-white, volume does the colour work.\n\n### Recipe 7 — Matte plastic (red)\n```python\nimport bpy\nmat = bpy.data.materials.new('MAT-plastic_matte_red')\nmat.use_nodes = True\nbsdf = mat.node_tree.nodes['Principled BSDF']\nbsdf.inputs['Base Color'].default_value = (0.8, 0.1, 0.05, 1.0)\nbsdf.inputs['Metallic'].default_value = 0.0\nbsdf.inputs['Roughness'].default_value = 0.6\nbsdf.inputs['IOR'].default_value = 1.45\nbpy.data.objects['GEO-target'].data.materials.append(mat)\nprint('material:plastic_matte_red')\n```\n\n### Recipe 8 — Lacquered plastic (car-paint look)\n```python\nimport bpy\nmat = bpy.data.materials.new('MAT-plastic_lacquered')\nmat.use_nodes = True\nbsdf = mat.node_tree.nodes['Principled BSDF']\nbsdf.inputs['Base Color'].default_value = (0.8, 0.1, 0.05, 1.0)\nbsdf.inputs['Metallic'].default_value = 0.0\nbsdf.inputs['Roughness'].default_value = 0.15\nbsdf.inputs['IOR'].default_value = 1.45\nbsdf.inputs['Coat Weight'].default_value = 0.8\nbsdf.inputs['Coat Roughness'].default_value = 0.05\nbpy.data.objects['GEO-target'].data.materials.append(mat)\nprint('material:plastic_l","tagline":"Create and assign PBR materials in Blender via Principled BSDF — metals, glass, plastic, fabric, skin, organics.
