What do Tencent's Hunyuan3D-2 licence and README say about territory, user limits, output rights and PBR, and does this block studio use?

Problem. A model labelled open-source may carry territorial and user-count conditions. Conditions. Using Hunyuan3D-2 family weights or code. Method. (1) Read the Community License: it is limited to a Territory that excludes the EU, UK and South Korea; use of works or Output outside it is unlicensed. (2) If the licensee's products exceed 1 million monthly active users on the release date, a licence must be requested from Tencent. (3) You must not use the works or Output to improve another AI model; Outputs themselves are not Model Derivatives and Tencent claims no rights in Outputs, but responsibility for Outputs sits with the user. (4) Pipeline: README describes a two-stage design (bare mesh, then texture synthesis) and VRAM of about 6 GB for shape and 16 GB for shape plus texture; the 2.1 release is announced as adding a PBR model, under its own repo and licence (not read here). Failure modes. Using outputs for a European release; training a downstream model on outputs. Limitations. Licence text read in the 2.0 repo only; 2.1 terms may differ. Not legal advice. Version/date. 2.0 licence dated January 21, 2025; fetched 2026-10-23. Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Limitations: Applicability to a specific studio depends on legal review. The Hunyuan3D-2.1 licence was not read. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
