QtMeshEditor Motion Corpus

A permissively-licensed animated-humanoid corpus: rigged 3D characters with skeletal animation clips, harvested for QtMeshEditor's text-to-motion v2 work (epic #837) — the template clip library and the training set for a from-scratch flow-matching motion model.

Every asset is CC0 or CC-BY — nothing here derives from Mixamo, LAFAN1, Bandai-Namco, AMASS/HumanML3D, or game rips (all license-poisoned for commercial redistribution). That makes this corpus — and anything trained on it — redistributable, including commercially, with the attributions in ATTRIBUTION.md.

Layout

manifest.json          per-asset provenance: source, source_url, title,
                       author, license, tags, files, and a validation record
                       (bone count, animation names, vertex count) produced
                       by the editor's own loader (`qtmesh info --json`)
ATTRIBUTION.md         CC-BY credits — ship this with derived works
raw/packs/...          Quaternius CC0 animated packs (FBX)
raw/opengameart/...    OpenGameArt CC0/CC-BY rigs (mixed formats)
raw/sketchfab/...      Sketchfab CC0/CC-BY downloads (glTF), when present

manifest.json also records discovery-only rows (license-cleared Sketchfab models not yet downloaded) — their source_url can be fetched with the scraper below.

Reproducing / extending

The corpus is produced by scripts/scrape-motion-corpus.py (license-filtered discovery + download + validation; incremental manifest):

python3 scripts/scrape-motion-corpus.py --out motion_corpus --packs \
    --opengameart "animated character" \
    --sketchfab "walk animation,run animation"   # SKETCHFAB_API_TOKEN to download

Re-running against this dataset's directory merges new finds into the manifest instead of overwriting it.

Provenance & licensing

Per-asset license and author live in manifest.json; the license filter accepts only CC0-1.0, CC-BY-3.0 and CC-BY-4.0 (exact-label matching — no NonCommercial/NoDerivs/ShareAlike variants). If you redistribute the corpus or ship anything derived from it (clip libraries, model weights), include ATTRIBUTION.md.
