| # ABO material-intrinsics WebDataset | |
| Preliminary publication smoke for the IDArb-compatible Amazon Berkeley Objects material-render | |
| conversion. The smoke shard contains 10 complete objects with 91 views and three environment | |
| lights per object. | |
| Each tar member is one compressed NPZ containing `rgb`, `albedo`, `roughness`, `metallic`, | |
| `normal`, `mask`, `depth`, and `meta_json`. Source-specific material channels, camera conventions, | |
| normal axes, masks, and background compositing are normalized during conversion. | |

| Production publication is in progress. Root `shard-*.tar` files contain exactly 500 unique objects | |
| except the final source remainder; matching provenance and SHA-256 records live under | |
| `manifests/`. `smoke/shard-000000.tar` remains the independently verified validation artifact. | |
