# Data license

Our annotations (recipes, instructions, camera rigs, checks, the chain index, the part masks, the part captions in
`data/captions/` and the annotation files in `data/annotations/`) are released under CC BY 4.0
(https://creativecommons.org/licenses/by/4.0/).

Meshes and textures (`data/parts/`, `data/states/`, the derived files in `data/recipes/`) and the renders of the states (`data/renders/`) come from source objects and keep the
license of the object they come from, listed with author and URL in `ATTRIBUTION.csv`:

- Objaverse objects, through PartVerse-XL (MIT): each object under its own Creative Commons license. 935 are CC BY 4.0, 1 is CC0,
  33 are CC BY-NC, 11 are CC BY-NC-SA and 9 are CC BY-SA. Objaverse is ODC-By 1.0 as a collection.
- 15 parts from HY3D-Bench (CC BY 4.0), whose original file URLs are listed in `ATTRIBUTION.csv`.

A state contains several separate parts, and each part keeps the license of its own object. `data/chains.json` lists, for every chain,
the licenses of all objects it uses. Material from CC BY-NC or CC BY-NC-SA objects may only be used for non-commercial purposes, and
adaptations of CC BY-SA or CC BY-NC-SA material must be shared under the same license.

Retexture turns use textures generated by us (Qwen-Image-Edit-2509 and TRELLIS.2) and baked into new UV layouts. Our contributions
to these files are licensed under CC BY 4.0; where the source object is CC BY-SA or CC BY-NC-SA, they are under the same license
as the object.
