# Asset provenance

## Original work

- **Elowen, initial model:** authored through Higgsfield 3D Jutsu / Blender. Editable source: `elowen.blend`. Project: https://higgsfield.ai/3d-jutsu/929bf75d-7ce9-4fd2-a846-3f1e54a0d823 .
- **Elowen, textured revision:** assembled and fitted in local Blender with `build_textured_hero.py`. Source: `elowen-textured.blend`; portable mesh: `elowen-textured.glb`; Unity conversion: `export_textured_hero.py`. Uses the CC0 MakeHuman assets and Poly Haven fabrics listed below, with original cape, staff and equipment. The earlier primitive model remains as editable history.
- **Cinematic title plate:** generated using ChatGPT's built-in image-generation tool for this project. `Assets/Resources/AetherfoldTitle.png`. It is title art, not a gameplay screenshot.
- **Four-dimensional architecture and realms:** original parameterized geometry in `Realms.cs` and `Geometry4D.cs`.
- **Score and sound effects:** original synthesized audio in `WeaveAudio.cs`.

## Poly Haven: CC0 assets

Poly Haven states that its textures, models and HDRIs are CC0 and may be redistributed inside games: https://polyhaven.com/license . Original asset authors are credited on the linked asset pages.

| Asset | Used for | Source |
| --- | --- | --- |
| Forest Floor | 2K albedo, normal, roughness and AO; terrain | https://polyhaven.com/a/forest_floor |
| Mossy Stone Wall | 2K weathered masonry materials | https://polyhaven.com/a/mossy_stone_wall |
| Mossy Cobblestone | 2K courtyard paving materials | https://polyhaven.com/a/mossy_cobblestone |
| Rock Face | 2K exposed island-cliff materials | https://polyhaven.com/a/rock_face |
| Tree Small 02 | Detailed tree; reduced to 180,000 triangles for runtime, 1K textures | https://polyhaven.com/a/tree_small_02 |
| Fern 02 | Four undergrowth models and 1K materials | https://polyhaven.com/a/fern_02 |
| Rock Moss Set 01 | Six photogrammetric rock meshes, runtime LODs | https://polyhaven.com/a/rock_moss_set_01 |
| Dead Tree Trunk 02 | Fallen logs and bark details | https://polyhaven.com/a/dead_tree_trunk_02 |
| Misty Pines | 2K HDR panoramic environment | https://polyhaven.com/a/misty_pines |

Source downloads and conversion scripts are retained under `Art-source/Environment`. Runtime-ready FBX meshes and textures are in `Assets/Resources/Environment`. No marketplace purchase or paid Higgsfield generation was used for these assets.

The scanned foliage and rocks are decorative 3D meshes with 4D-positioned anchors and thickness-dependent visibility. Collision-bearing terrain and puzzle walls remain exact 4D volumes. This distinction is documented rather than presenting decorative mesh effects as a general 4D modeler.

Cherry trees were modeled procedurally in local Blender for this project; see cherry_tree.py and cherry-tree.blend. Ruined arcades and castle masonry are original four-dimensional box geometry. Fog is an original animated shader; the misty-pines HDRI is retained for environment lighting, not as the visible background.


## Seasons redesign

Eight original ChatGPT concept paintings are used in chapter cards and realm menus. Prompts, themes and source output paths: `Concepts/manifest.json`. Runtime files: `Assets/Resources/RealmArt/*.png`. These are illustrations, not screenshots of the live game. Generation used the built-in ChatGPT image tool, with no Midjourney or paid Higgsfield call in this revision.

Additional 2K CC0 color and OpenGL normal maps from Poly Haven:

| Material | Source |

| White Sandstone Bricks | https://polyhaven.com/a/white_sandstone_bricks |
| Marble Mosaic Tiles | https://polyhaven.com/a/marble_mosaic_tiles |
| Medieval Red Brick | https://polyhaven.com/a/medieval_red_brick |

| Marble Cliff 01 | https://polyhaven.com/a/marble_cliff_01 |
| Brick Floor | https://polyhaven.com/a/brick_floor |

Download metadata: `Concepts/materials.json`; downloader: `download_season_materials.py`. Original architectural crowns, seasonal weather, procedural plants, clothing accessories and realm surfaces are authored in the Unity source. Curved roof decorations use 4D anchors, like the scanned foliage.

## Detailed environment revision

The following additional CC0 Poly Haven models are used with their UVs, diffuse maps, normals, roughness and separate vegetation cutouts where supplied. The original authors are listed on each asset page. Source metadata and downloaded files are retained in `Realism`; runtime catalog and material slot assignments are in `Assets/Resources/Realism/catalog.json`.

Eight original architectural meshes are generated by `build_heritage_kit.py`: a Gothic arcade, domed pavilion, geared orrery, timber stave hall, Venetian loggia, stepped temple, organic sanctuary and classical rotunda. They use the credited Poly Haven materials. These are detailed 3D decorations attached to 4D positions; the exact collision and slicing remain in the underlying 4D geometry.

## MakeHuman: CC0 core assets

The anatomical base mesh, young light-skinned female diffuse skin, braid01 hair, male_casualsuit03 fitted clothing topology, and shoes02 boot mesh/textures come from the [MakeHuman core system asset pack](https://static.makehumancommunity.org/assets/assetpacks/makehuman_system_assets.html). The pack explicitly lists these core assets as CC0. [License explanation](https://static.makehumancommunity.org/about/license.html). The clothing is refitted and retextured with the credited wool and leather for this game's character. No MakeHuman application code is incorporated into the game.

Original pack and data are retained under `Realism/makehuman`. No paid asset purchase, Higgsfield credits or Midjourney generation was used in this realism revision.

`build_cliff_mass.py` creates original eroded cliff supports using the credited Rock Face material.
