Create and assign PBR materials in Blender via Principled BSDF — metals, glass, plastic, fabric, skin, organics. Covers physically-based material recipes with real-world values, Coat layer (varnish/car paint), Sheen (cloth), Subsurface scattering (skin/wax), Transmission (glass),
Create and assign PBR materials in Blender via Principled BSDF — metals, glass, plastic, fabric, skin, organics. Covers physically-based material recipes with real-world values, Coat layer (varnish/car paint), Sheen (cloth), Subsurface scattering (skin/wax), Transmission (glass), and procedural patterns (wood grain, marble, fabric weave). Use whenever the user asks to "make it look like X material", "give it a metallic finish", "apply a wood texture", "make this glass / plastic / brushed steel / leather / skin", or any look-development request. Make sure to use this skill even if the user does not say "material" — also covers "make it shiny", "matte finish", "looks like copper", "rough surface". Works with any geometry; pairs with blender-lighting (materials only look right under proper lighting).
Source documentation, not instructions for this website. Review permissions before running any commands.
Apply physically-based materials to objects. Use only Principled BSDF — it's the only shader that exports cleanly to glTF and matches what other DCC tools expect.
The 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."
Exception: dark mirror lenses (sunglasses) use ~0.8 to combine strong reflection with slight tint — that's a stylistic choice, not strict PBR.

If 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.
Each recipe creates the material and assigns it to a target object. Replace 'GEO-target' with your actual object name.
set_input helper — required for some Blender 5.x BSDF inputsIn 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.
Use 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:
def set_input(node, name, value):
"""Set a node input by name. Works on inputs with enabled=False
that fail string-key lookup (e.g. 'Subsurface IOR' on Blender 5.x).
"""
for inp in node.inputs:
if inp.name == name:
inp.default_value = value
return True
return False
For 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.

Using 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.
Pattern: keep the surface near-white with slight roughness, attach a Volume Absorption shader to the Material Output's Volume input.

# Surface: near-white with tiny roughness (breaks mirror-finish look)

links.new(volume.outputs['Volume'], output.inputs['Volume'])
bpy.data.objects['GEO-target'].data.materials.append(mat)
print('material:glass_wine_volume_absorption')
Tuning Density: 0–10 = very subtle tint (clear bottle); 20–40 = clear bottle-green or amber; 60–100+ = nearly opaque (cobalt-blue medicine bottle).
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.
Other coloured-glass examples (density values updated v0.9.0 after subject-class lighting fix):
| Name | Volume Color | Density | Surface tint |
|---|---|---|---|
| Wine bottle (deep green) | (0.05, 0.32, 0.10) | 80 | near-white |
| Pale tinted (clear vial) | (0.10, 0.45, 0.18) | 15 | near-white |
| Champagne / pale gold | (0.85, 0.65, 0.30) | 25 | near-white |
| Cobalt blue (medicine bottle) | (0.10, 0.20, 0.85) | 80 | near-white |
| Amber / brown beer bottle | (0.80, 0.40, 0.10) | 70 | near-white |
| Ruby red | (0.85, 0.10, 0.15) | 100 | near-white |
Density tuning rule of thumb under neutral/glass-class lighting:
If 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.
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.
scene.cycles.transmission_bounces = 24
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.

# Blender Materials
Apply physically-based materials to objects. Use **only Principled BSDF** — it's the only shader that exports cleanly to glTF and matches what other DCC tools expect.
## The metallic switch — never an in-between
The 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."
Exception: dark mirror lenses (sunglasses) use ~0.8 to combine strong reflection with slight tint — that's a stylistic choice, not strict PBR.

## Reference-look handoff
If 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.
## Recipes (the 12 to know)
Each recipe creates the material and assigns it to a target object. Replace `'GEO-target'` with your actual object name.
### `set_input` helper — required for some Blender 5.x BSDF inputs
In 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.
Use 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:
```python
def set_input(node, name, value):
"""Set a node input by name. Works on inputs with enabled=False
that fail string-key lookup (e.g. 'Subsurface IOR' on Blender 5.x).
"""
for inp in node.inputs:
if inp.name == name:
inp.default_value = value
return True
return False
```
For 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.
### Recipe 1 — Brushed steel
```python
import bpy
mat = bpy.data.materials.new('MAT-steel_brushed')
mat.use_nodes = True
bsdf = mat.node_tree.nodes['Principled BSDF']
bsdf.inputs['Base Color'].default_value = (0.56, 0.57, 0.58, 1.0)
bsdf.inputs['Metallic'].default_value = 1.0
bsdf.inputs['Roughness'].default_value = 0.25
obj = bpy.data.objects['GEO-target']
if obj.data.materials:
obj.data.materials[0] = mat
else:
obj.data.materials.append(mat)
print(f"material:MAT-steel_brushed→{obj.name}")
```
### Recipe 2 — Polished gold
```python
import bpy
mat = bpy.data.materials.new('MAT-gold_polished')
mat.use_nodes = True
bsdf = mat.node_tree.nodes['Principled BSDF']
bsdf.inputs['Base Color'].default_value = (1.022, 0.782, 0.344, 1.0)

bsdf.inputs['Base Color'].default_value = (1.0, 1.0, 1.0, 1.0)
bsdf.inputs['Transmission Weight'].default_value = 1.0
bsdf.inputs['IOR'].default_value = 1.5
bsdf.inputs['Roughness'].default_value = 0.3
bpy.data.objects['GEO-target'].data.materials.append(mat)
print('material:glass_frosted')
```
### Recipe 6b — Coloured glass (wine bottle, tinted vials, decorative glass)
Using 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.
Pattern: keep the surface near-white with slight roughness, attach a `Volume Absorption` shader to the Material Output's `Volume` input.
```python
import bpy
def set_input(node, name, value):
for inp in node.inputs:
if inp.name == name:
inp.default_value = value
return True
return False
mat = bpy.data.materials.new('MAT-glass_wine')
mat.use_nodes = True
nodes = mat.node_tree.nodes
links = mat.node_tree.links
bsdf = nodes['Principled BSDF']
output = nodes['Material Output']
# Surface: near-white with tiny roughness (breaks mirror-finish look)
set_input(bsdf, 'Base Color', (0.85, 0.95, 0.85, 1.0)) # near-white
set_input(bsdf, 'Metallic', 0.0)
set_input(bsdf, 'Roughness', 0.025) # critical: not 0.0; that looks metallic
set_input(bsdf, 'Transmission Weight', 1.0)
set_input(bsdf, 'IOR', 1.52) # bottle glass
# Volume Absorption — depth-based tint
volume = nodes.new('ShaderNodeVolumeAbsorption')
set_input(volume, 'Color', (0.10, 0.45, 0.18, 1.0)) # saturated wine-bottle green
set_input(volume, 'Density', 30.0) # higher = more colour over short distance
links.new(volume.outputs['Volume'], output.inputs['Volume'])
bpy.data.objects['GEO-target'].data.materials.append(mat)
print('material:glass_wine_volume_absorption')
```
**Tuning Density**: 0–10 = very subtle tint (clear bottle); 20–40 = clear bottle-green or amber; 60–100+ = nearly opaque (cobalt-blue medicine bottle).
**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.
**Other coloured-glass examples** (density values updated v0.9.0 after subject-class lighting fix):
| Name | Volume Color | Density | Surface tint |
|------|-------------|---------|---------------|
| Wine bottle (deep green) | (0.05, 0.32, 0.10) | 80 | near-white |
| Pale tinted (clear vial) | (0.10, 0.45, 0.18) | 15 | near-white |
| Champagne / pale gold | (0.85, 0.65, 0.30) | 25 | near-white |
| Cobalt blue (medicine bottle) | (0.10, 0.20, 0.85) | 80 | near-white |
| Amber / brown beer bottle | (0.80, 0.40, 0.10) | 70 | near-white |
| Ruby red | (0.85, 0.10, 0.15) | 100 | near-white |
**Density tuning rule of thumb under neutral/glass-class lighting**:
- Density 5–15 = subtle hint of colour (clear + tinted)
- Density 30–50 = medium tint visible at thin sections
- **Density 60–100 = proper wine/beer/cobalt bottle look** (recommended for hero shots)
- Density 100+ = nearly opaque (artistic / decorative)
If 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.
**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.
```python
scene.cycles.transmission_bounces = 24

**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.
