# 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.

CVPR 2022 paper when using it.
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.
