Licenses & legal findings
Every third-party model/dataset/tool that touches the pipeline gets a row here with its license, commercial status, link, and the date checked. See PLAN.md §Ground rules.
2026-07-17 correction (session 2): B1's original row billed MoCapAnything as the human engine — it is an animal model (see
DECISIONS.md). The SMPL/SKEL gate is LIVE, not avoided. Rows below corrected and license-verified.
Components
| Component | License (code / body model) | Commercial OK? | Notes | Checked |
|---|---|---|---|---|
| HSMR (human — candidate engine) | code MIT / body SKEL | code yes / model NO | IsshikiHugh/HSMR, CVPR25 oral. Predicts SKEL params (biomechanical skeleton, great for retarget). Needs SKEL files (NC) at inference. MPS-runnability unverified. |
2026-07-17 |
| SKEL-CF (human — candidate) | code (verify) / body SKEL | model NO | Coarse-to-fine skeleton+mesh, Nov 2025. Same SKEL gate. | 2026-07-17 |
| SKEL body model | MPG research | NO (default) | "any use for commercial… purposes is prohibited"; commercial via ps-license@tue.mpg.de. Same family as SMPL. | 2026-07-17 |
| SMPL / SMPL-X body model | MPG research (Meshcapade sublicenses) | NO (default) | Commercial via sales@meshcapade.com (quote-based; incl. SMPL+H/-X/STAR). Gate for all SMPL-based human models. | 2026-07-17 |
| GVHMR / WHAM / TRAM / OnlineHMR (human, SMPL) | research/NC (GVHMR NC confirmed) / SMPL | NO | Accuracy leaders but double gate: NC code AND SMPL. GVHMR commercial via xwzhou@zju.edu.cn. Reference/yardstick unless licensed. | 2026-07-17 |
| GEM-X (human, shelved) | Apache / SOMA (not SMPL) | yes, but off-fleet | NVIDIA commercial-ready; CUDA-only → won't run on Apple Silicon. Revisit only if the fleet gains NVIDIA. | 2026-07-17 |
| MoCapAnything V2 (animal — creature NPCs only) | MIT / none | YES (creatures) | kehong/MoCapAnythingV2-weights MIT, no SMPL. 71 animal targets, no human/biped/fingers → NOT the human engine. Keep for creature/centaur (Lane E4) work. |
2026-07-17 |
| AMASS dataset | academic | verify before shipped training | Lane E only | — |
BioAMASS v1.0 (downloaded, ~/Documents/skel/bioamass_v1.0: CMU, DFAUST, MPI_Limits subsets, 376MB) |
MPG research (same SKEL account/licence) | NO (default) — same NC family; Lane E training that ships needs the same Path-A licence email | SKEL-fitted mocap — ideal Lane E2 autoposer training data format-wise; legal gate identical to SKEL itself | 2026-07-17 |
| Mixamo clips | Adobe ToS | ship-in-game OK; not ML training data | — | — |
The SMPL/SKEL gate (hard stop — LIVE, John decision)
Every accurate world-grounded human model depends on a Max-Planck body model — SMPL (GVHMR/WHAM/TRAM/OnlineHMR) or SKEL (HSMR/SKEL-CF) — both research-licensed. Two paths:
- Path A — license it. Email MPI (SKEL,
ps-license@tue.mpg.de) or Meshcapade (SMPL,sales@meshcapade.com) for an indie commercial license. Clean; quote-based. - Path B — SMPL-free outputs. Run an MIT-code model (HSMR) locally, keep only joint rotations, retarget onto our own mixamorig, distribute no Max-Planck file. Grey area: the NC license bars "production of artefacts for commercial purposes." John-accepts-risk.
Decision lives in docs/DECISIONS.md. The human path does not proceed until John picks.
