## Textures

- Surface textures from [Poly Haven](https://polyhaven.com) — CC0: `large_sandstone_blocks_01`, `sandstone_blocks_08`, `sandstone_cracks` and `sand_01` by Rob Tuytel; `rock_face_03` by Dario Barresi and Rico Cilliers. Sources in `art/textures/sources.json` (the scans; the game ships them as KTX2 in `public/textures`).

## Models

- Art direction, interface and identity: the Claude Design canvas described in [docs/art/README.md](docs/art/README.md).
- Props and level art (`public/models`): procedural, built in Blender by the prop kit (`scripts/blender`) and in code (`src/render`).
- Nora Vidal: a Meshy model from the owner's reference, decimated and rigged in Blender (`scripts/character/rig_nora.py`).
- The guardians (Tamrit, Bazûr, the automatons, Anzur), the keepers' statues, the relics and the chambers' objects (from the kiln to the great seal): Meshy models generated for the project from the prompts and concept images in `docs/art/`, fitted with `pnpm models:fit`.
- Indirect light baked with Blender Cycles (`scripts/bake`).

## Animation

- Nora's motion clips (`public/anim/*.json`) are **Mixamo** animations (Adobe, https://www.mixamo.com), made on Nora's own mesh and retargeted onto her game skeleton: Breathing Idle, Walking, Walking Backwards, Running, Run To Stop, Left/Right Turn 90, Jump, Running Jump, Falling Idle, Falling To Landing, Hanging Idle, Braced Hang Shimmy (and mirror), Braced Hang To Crouch, Pushing, Picking Up, Hit Reaction, Dying, Pistol Idle, Pistol Run, Shooting, Treading Water, Swimming and Swimming To Edge. Mixamo animations are free to use in games (royalty-free, per Adobe's Mixamo terms). The FBX downloads are not in the repo; `pnpm anim:build scripts/anim/sources/mixamo.json <folder>` rebuilds the clips (see `docs/animation.md`).
- Earlier clips came from the **Universal Animation Library** (Standard) by [Quaternius](https://quaternius.com), CC0 1.0; the pipeline still supports it (`scripts/anim/sources/ual.json`).
- Procedural animation layer (climbing, mechanisms, aiming) in `src/render/nora.ts`.
