Problem. Research mocap code often ships with non-commercial terms. Conditions. Commercial or client work. Method. (1) WHAM's LICENSE is MIT (copyright Soyong Shin), but its README requires registering at the SMPL and SMPLify sites to download body models, which have their own licence terms (not read in full here). (2) GVHMR's LICENSE permits use, copying, modification and distribution for educational, research and non-profit purposes only, requires modifications to be open source and prohibited for commercial use, and directs commercial users to email the authors. (3) So WHAM code may be usable but is gated by SMPL; GVHMR needs a separate commercial licence. Failure modes. Treating GitHub 'MIT' as covering the SMPL model. Limitations. SMPL's own licence page was fetched but not analysed in this round; dataset terms (AMASS) are covered by earlier items C2-B14-D2-09 and C2-B40-RD-05. Version/date. Fetched 2026-10-23.
