# Texture credits

Every texture shipped under `public/assets/tex/` and every texture baked into a model under
`public/assets/models/` comes from **[Poly Haven](https://polyhaven.com)** and is licensed

required — we credit the authors anyway). No brand marks.

Machine-readable list: `scripts/assets/polyhaven.json`. Raw maps are not in git; rebuild them with
`node scripts/assets/fetch-polyhaven.mjs` (2K + 1K JPG: diff, nor_gl, rough, ao, disp, arm, metal where
available). A shipped file carries the Poly Haven id in its name (e.g. `tex/asphalt_02.<hash>.ktx2`, or a
packed detail array listing its layer ids below), so each file maps to a line here.
