# Fjordfall — asset credits

Fjordfall's roads, terrain, sky, weather, physics, animation and much of its
sound are generated by the game. Optional images, models and recorded sound
upgrade the procedural versions when available.

| Assets | Provenance |
| --- | --- |
| `env/kiara_9_dusk_1k.hdr` | Poly Haven, [Kiara 9 Dusk](https://polyhaven.com/a/kiara_9_dusk), CC0. Used only with the optional photographic environment. |
| `tex/asphalt.webp`, `rock.webp`, `moss.webp`, `snow.webp`, `gravel.webp` | Generated with OpenAI `gpt-image-2.5-sunburst-2026-09-08`. Recipes: `tools/gen/game-images.json`; each image has a `.webp.json` provenance sidecar. |
| `tex/water_ripple.webp` | Earlier generated water detail, retained. |
| `tex/weathered_timber.webp`, `tex/cabin_paint.webp`, `tex/ground_transition.webp`, `tex/lichen.webp` | Generated with OpenAI `gpt-image-2.5-sunburst-2026-09-08` through the project image tool. Prompts in `tools/gen/game-images.json`; individual `.webp.json` sidecars retain request IDs, hashes and usage. |
| `ui/field-paper.webp` | Generated with OpenAI `gpt-image-2.5-sunburst-2026-09-08`. Recipe: `tools/gen/game-images.json`; generation provenance: `ui/field-paper.webp.json`. Used beneath live map and memory content. |
| `ui/postcard-border.webp` | Generated with OpenAI `gpt-image-2.5-sunburst-2026-09-08`. A transparent nine-slice frame around game captures in memories and downloaded postcards. Provenance: `ui/postcard-border.webp.json`. |
| Rider | Meshy source mesh and 24-joint auto-rig, refined and animated in Blender through the Blender Lab MCP add-on. Six authored actions provide idle, walking, jogging, cruising, tucking and pushing. Game physics and inverse kinematics retain control of board contact and balance. Provenance: `models/rider.glb.json`; editable source: `art/character/fjordfall-rider.blend`. |
| Board, boulders, summit hut, waterfront buildings and rowboat | Generated with Meshy. |
| Barn, farmhouse (retextured 2026-09-12: Meshy retexture on the same mesh, base colour only, 512 px, meshopt), stabbur, seterbu, ferjeskur, birch, spruce, sheep, moose, car, bus, tractor and ferry | Meshy assets shared with the Godot edition. Browser editions use Meshopt compression and 512px WebP textures. |
| `sfx/*.mp3` | Generated with ElevenLabs sound tools. Procedural audio supplies missing clips and additional environmental sounds. |
| App icons, postcard layout and typography | Original vector and browser graphics for Fjordfall, with generated paper and border materials. |
| Social preview | Captured from the game, with original typography and layout. |
| `models/oslo-kit.glb` | Original Blender game models: Oslo Opera House (inspired by Snøhetta), Holmenkollen (inspired by JDS Architects), and four townhouse variants. Recipe: `tools/blender/oslo.py`; editable source: `art/oslo/oslo-landmarks.blend`. No reference photography is distributed as texture or geometry. |

Current model prompts are preserved under `tools/gen/` in the source repository.
Earlier asset-generation prompts and tooling are in the project's Git history.
`tools/import_godot_assets.mjs` builds the compressed landscape models from the
Godot edition; the native source files remain intact.

Built with [Three.js](https://threejs.org), including its glTF loaders and
