06 Material Studies

Material studies prove that surfaces read before final rendering.

Test Matrix

| Material | What to Test | Pass Criteria |

| --- | --- | --- |

| Metal | hard highlight, cool shadow, edge hits | recognized at 50% scale |

| Leather | soft highlight, warm shadow, creases | not confused with fabric |

| Cloth | broad clusters, low specular response | folds read without noise |

| Rubber | muted highlight, thick darks | reads flexible and durable |

| Stone | chipped clusters, low saturation | not over-detailed |

| Energy | glow core, rim light, transparency cue | direction and source are readable |
