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...
