+# EditHero data
+
+EditHero is a benchmark for long-horizon, part-level 3D editing. Each chain starts from a textured, part-segmented host object and
+applies a sequence of edits (add, remove, replace, retexture), each with a natural-language instruction and an exact target state.
+457 chains, 2,755 edits, 3,212 states, 252 host objects.
+
+Paper and project page: https://alaya-lab.github.io/EditHero/. Code (data engine, rebuild, render script):
+https://github.com/AlayaLab/EditHero.
+
+## Browse
+
+The dataset viewer above shows every edit (2,755 rows): chain, turn, operation, the cond view of the state before and after the
+edit, the mask of the edited parts in that view, and the instruction. The same table is in `preview/*.parquet`:
+
+```python
+from datasets import load_dataset
+edits = load_dataset("AlayaLab/EditHero", "edits", split="test")
+```
+
+`sample/` holds one complete chain (A/1a3267df_s0) unpacked, with its instructions (`sample/chain.json`, `sample/README.md`).
+
+## Download
+
+Everything except the index files and the captions comes as uncompressed tars, one per chain family (A, G, M, P, R, X), per part source, and one for the annotation files.
+Download what you need and extract it in the same folder; the tars recreate the `data/` layout below.
+
+```bash
+huggingface-cli download AlayaLab/EditHero --repo-type dataset --local-dir EditHero
+cd EditHero && for t in data/*/*.tar; do tar -xf "$t" && rm "$t"; done
+# only some of it, e.g. the renders and part masks:
+huggingface-cli download AlayaLab/EditHero --repo-type dataset --local-dir EditHero --include "data/renders/*" "data/part_masks/*" "data/*.json"
+```
+
+
+## Layout
+
+| Path | Contents |
+|---|---|
+| `data/chains.json` | Index of the chains: host object, operations, instructions, licenses of the source objects the chain uses |
+| `data/cameras.json` | Fixed four-view camera rig per chain. View 0 is the conditioning view (`cond`), views 1-3 are held out (`heldout`) |
+| `data/states/<chain>/turnNN.glb` | The correct state after every turn (turn00 is the initial object) |
+| `data/renders/<chain>/turnNN/view{0..3}_{cond,heldout}.png` | Every state rendered with the chain's rig (420 x 420, RGBA) |
+| `data/part_masks/<chain>/turnNN/{source,target,edit}_view{0..3}_{cond,heldout}.png` | Pixels of the parts edited in turn NN, in the same four views: `source` = those parts in the previous state, `target` = in the new state, `edit` = union. `masks.json` per chain lists the edited nodes and pixel counts |
+| `data/recipes/<chain>/` | The recipe of each chain (`place_report.json`, `turn00_manifest.json`, `checks.json`, `provenance.json`) and the derived files it uses (retexture bakes, edited part copies) |
+| `data/parts/` | Every part the recipes use: `partverse_xl/<object>/<part>.glb` from PartVerse-XL, `hy3d/<object>/<part>.glb` from HY3D-Bench (textured by us) |
+| `data/captions/captions_qwen3.json` | Captions of the whole PartVerse-XL library (37,348 objects, 324,375 parts): per object `{"object": [brief, detailed], "parts": {"<pid>": [brief, detailed]}}`, written by Qwen3-VL-32B. The engine retrieves parts by these captions |
+| `data/captions/hy3d_captions.json` | Captions and bounding boxes of the HY3D-Bench parts in the part library (Qwen3-VL-8B) |
+| `data/annotations/assembly/A/<chain>/` | Every intermediate file of the 97 family-A chains that assemble a host from its own parts: planner input (`parts.json`), assembly plan (`plan.json`), annotator brief, Qwen draft, agent revision, left/right check, relational rewrite and Qwen check of the instructions (shipped as `data/annotations/assembly.tar`). The pipeline and its prompts are in the code repository (`part_assembly/annotate/`) |
+| `ATTRIBUTION.csv` | Every source object: uid, source, title, author, URL, license, chains that use it |
+
+An editing method gets the instruction and, if it takes an image, the `cond` view of the target state. The `heldout` views are for
+checking the result from angles the method never saw.
+
+## Rebuild and render
+
+The states and renders are included, so nothing has to be rebuilt to use the data. To regenerate a chain from its recipe and verify
+it with the code repository:
+
+```bash
+python part_assembly/tools/assemble.py --pv-root data/parts/partverse_xl --hy3d-root data/parts/hy3d \
+    --chain data/recipes/A/1a3267df_s0 --out out/A_1a3267df_s0
+# PASS A/1a3267df_s0 (verified vs checks.json)
+```
+
+The instructions in `chains.json` were rewritten from the engine's template sentences (kept in every recipe record as
+`instruction_original`) by the rules in the code repository's `docs/INSTRUCTIONS.md`, and reviewed by us.
+
+Every state is verified node by node (vertex count, sum of |v|, texture hashes) against `checks.json`. All renders were made with
+[blender_kit](https://github.com/AuroraRyan0301/Blender-Visualization-Skill) (Blender 4.2, Cycles); `scripts/render_state.py` in
+the code repository renders any state, or your own edited GLB, with a chain's rig. If blender_kit saves you an afternoon of arguing
+with Blender, a ⭐ on it would make its author's day.
