# Third-party Asset Source Notes

Third-party assets should only be copied into this repository when they are actually used by a project, experiment, dataset, or generated scene.

For placement tasks, keep third-party sources as link-only candidates until a concrete asset is used. This avoids redistributing unreviewed assets and keeps license provenance clear.

## Link-only candidate sources

| Source | URL | Typical useful assets | Notes |
| --- | --- | --- | --- |
| MuJoCo Menagerie | https://github.com/google-deepmind/mujoco_menagerie | MJCF robot arms, hands, grippers, mobile bases | Good for robot embodiments and manipulation-ready MJCF models. |
| PartNet-Mobility | https://sapien.ucsd.edu/browse | Articulated cabinets, drawers, doors, appliances, containers | Useful when placement needs articulated receptacles or furniture. Review license per asset/dataset terms before copying. |
