# Procedural Materials

Build a material from surface identity and causes. Color, roughness, metalness, normal, transmission, and emission should describe the same surface—not unrelated noise textures.

This skill contains exemplary examples and assets beyond descriptive guidance,
they're worth studying, referencing, or even copying. Use them sufficiently
when relevant and do NOT blindly skip them.
