# NL3D anonymized multi-object review sample

This is an anonymized review-time sample selected from the NL3D synthetic
multi-object split. It contains 8 settled multi-object scenes and 26 unique
source GLBs, with no repeated source object across selected scenes. It is not
the complete synthetic training set.

## Selection

- `scenes/mixed`: 3 scenes containing both conductor and transmissive materials.
- `scenes/transparent`: 3 scenes emphasizing transmissive/clear materials.
- `scenes/metal`: 2 scenes emphasizing conductor and mirror-like reflection.

Every scene is copied in full. The original 50-view `rgb`, `diffuse`, `glossy`,
`transmission`, and `mask` directories are retained, together with
`transforms.json`, `composition.json`, `material.json`, `mesh_raw.ply`, and
`points_gt.ply`.

The referenced source assets are deduplicated under
`objects/objaverse_lvis_real`. All object references in the metadata use
portable repository-relative paths. HDR environments are identified by their
source filenames without retaining local machine paths.

## Provenance and licensing note

The source meshes are a curated subset of Objaverse assets. This sample does
not assign a new license to those third-party source assets; downstream users
must verify the applicable per-object provenance and license before further
redistribution. The complete NL3D data and documentation will be released after
the double-blind review period.
