[v1.0.0] — 2026-05-02 (initial release)

Added

• Blender indoor data drop: 374 scene instances (sence_indoor_0001 … sence_indoor_0374), 13,631 ERP RGB frames + 12,634 range-depth NumPy arrays + 13,631 pose JSON files. Resolution 2048×1024. CC-BY 4.0.
• Blender indoor metadata: source_manifest.json, splits.json (scene-level 70/15/15 via sha256(scene_id) % 100), frame_manifest.csv (14 columns matching the Croissant RecordSet schema), scene_id_mapping.csv and frame_id_mapping.csv (back-references to original H100 round1+2 / round2 sampling).
• Per-archive integrity: blender_indoor/SHA256SUMS (39,896 lines covering panorama + depth + pose).
• Adapter packages for the four license-restricted sources: HM3D (401 rooms), ScanNet++ (500 scans), OB3D (24 instances, outdoor), TartanGround (762 parts, outdoor). Each package contains README, config, pipeline / re-encoding script, and metadata/source_manifest.json listing the upstream scene IDs needed to reproduce the curator's selection.
• Curator source code (code/): MIT-licensed core modules (core/), scripts (scripts/), helper tools (tools/), metadata schemas (metadata_examples/), tiny example (examples/tiny_blender_scene/), environment.yml, requirements.txt.
• Croissant v1.0 metadata (croissant.json): conforms to http://mlcommons.org/croissant/1.0; passes mlcroissant 1.1.0 validator. 12 distribution entries (Blender archive + 4 FileSets + 4 adapter packages + code + docs + frame-manifest), 1 RecordSet (erp-frame-records) with 14 fields, 9 RAI extension fields.
• Datasheet (in README.md) following Gebru et al. 2021.
• License matrix (LICENSE.md).
• Top-level integrity manifest (SHA256SUMS) covering all non-data files.

Notes

• The paper's headline numbers 326 scenes / 11,583 frames describe the curator-selected subset, not the full data drop. v1.0 stages the underlying 374 / 13,631; the curator-selected subset will be derived after the §5 evaluation experiments finalize and posted as v1.1.
• HM3D / ScanNet++ / TartanGround / OB3D: zero RGB-D frames are redistributed under any license. The adapter packages reproduce matching frames on the user's machine after upstream access is granted.
• Frame numbers within each Blender scene are renumbered consecutively (panorama_0000 … panorama_NNNN); frame_id_mapping.csv records the back-reference to the original H100 file path for traceability.
