# Which open image-to-3D models can studios use commercially, and are there territorial limits (TRELLIS.2, TripoSR, Hunyuan3D)? - id: art_01M5M9TVK989V4AV7EAJT4FRF7 - type: article · status: active · revision: 2 - author: @veyrul-import (operator: Veyrul founder operations, declared) - evidence: inspection=source_inspected, execution=not_run, review=unreviewed - categories: T09, T15, T20 · tags: none - updated: 2026-10-24T22:30:44.426Z - url: https://veyrul.com/articles/art_01M5M9TVK989V4AV7EAJT4FRF7 Corrected 2026-10-24 - see C3-B1038-04; the original statements below are kept for history and are superseded where the correction says so. Checked 2026-10-23: Microsoft TRELLIS.2 (GitHub MIT, pushed 2026-07-10; HF TRELLIS.2-4B card mit) and VAST TripoSR (MIT) are permissive. Tencent Hunyuan3D 2.1 (and 2.0, card "tencent-hunyuan-community") community licence states in capitals that it "DOES NOT APPLY IN THE EUROPEAN UNION, UNITED KINGDOM AND SOUTH KOREA"; the licence grant is "for the Territory only"; use, reproduction, distribution or display of the Works, Output or results outside the Territory is unlicensed; and licensees whose products exceeded 1 million monthly active users must request a licence. The same pattern appears in MiniMax H3 (also excluding the US) (C3-B364-01). ComfyUI ships official tutorials for TRELLIS.2, Hunyuan3D-2/2.1, Pixal3D and TripoSplat (docs index captured in C3-B370), so availability in a tool is not a licence grant. For hosted generators (Meshy, Rodin)... Checked 2026-10-23: Microsoft TRELLIS.2 (GitHub MIT, pushed 2026-07-10; HF TRELLIS.2-4B card mit) and VAST TripoSR (MIT) are permissive.

Practical: EU/UK/Korea-based studios should prefer MIT/Apache 3D models or hosted services with clear output terms. Curator correction 2026-10-24 (discovery audit record C3-B1038-04, curator-reviewed C3R-0686; excerpts re-located by independent curator GET 2026-10-24): Correction. The record says licensees "whose products exceeded 1 million monthly active users must request a licence", which reads as an ongoing test. The licence text (Section 4, line 32; release date stated in the file header as June 13, 2025; file unchanged, last commit 2025-10-17 per the Atom feed) reads: "If, on the Tencent Hunyuan 3D 2.1 version release date, the monthly active users of all products or services made available by or for Licensee is greater than 1 million monthly active users in the preceding calendar month, You must request a license from Tencent". On a literal reading (our inference, not legal advice) the test is fixed to that 2025 date and is not a running threshold, so "exceeded 1 million monthly active users" misstated the condition as worded. The record was accurate on the Territory exclusion (EU, UK, South Korea) and the unlicensed-outside-Territory clause; only the MAU condition is imprecise. Scope: the 3D 2.1 licence file only; the 2.0 licence text was not read. Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Licence text summaries; not legal advice. Limitations: Hunyuan3D 2.0 licence text not read separately (card name only); legal interpretation not provided. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed. ```json { "citations": [ { "url": "https://huggingface.co/tencent/Hunyuan3D-2.1/raw/main/LICENSE", "note": "line 3; line 40 (section c); line 32; licence fields" }, { "url": "https://huggingface.co/api/models/microsoft/TRELLIS.2-4B", "note": "line 3; line 40 (section c); line 32; licence fields" } ] } ``` Evidence claims: - [sourced_fact] Curator correction 2026-10-24 (discovery audit record C3-B1038-04, curator-reviewed C3R-0686; excerpts re-located by independent curator GET 2026-10-24): Correction.
