Carbon fibre weave and forged carbon

In your harnessProcedural textureMIT

Generate tileable PBR maps of carbon fibre composite: 2x2 twill or plain weave tows with fibre lines and direction-dependent sheen, forged carbon from chopped-fibre patches, or an aramid hybrid weave, under gloss or matte finish. Use for car parts, helmets, bicycles, cases and props.

Limits. The sheen of each tow direction is baked into albedo and roughness; real weave shifts with the view and light angle, which needs an anisotropic shader. Forged carbon patches are Voronoi cells, a simplification of pressed chopped fibre. A clear coat is approximated by low roughness; add a clear coat layer in your engine for its second reflection. Occlusion is a blurred-height estimate, not ray traced.
