+Steam, worldwide, the EU included, so the licence of the output decides
+before the quality does. Hunyuan3D (every version) is out: Tencent's
+licence excludes the EU, UK and South Korea, and whether a game shipped
+there with its outputs is "use in the Territory" is not a question to
+leave to a court. In, in this order: **TRELLIS.2** shape (MIT; the best
+geometry; its own texture baking goes through nvdiffrec and nvdiffrast,
+both under NVIDIA's non-commercial source licence, so that stage is not
+run), **Step1X-3D** (Apache 2.0, StepFun; shape and texture in one, the
+EU-safe textured path — its ComfyUI node and VRAM need are to be
+checked), **Direct3D-S2** (MIT, DreamTech; high-detail shape, has a
+ComfyUI node) if TRELLIS.2's detail falls short. Not in: TripoSR and
+InstantMesh (permissive but superseded), Stable Fast 3D (Stability's
+community licence, revenue-capped), SAM 3D Objects (Meta's own licence,
+to be read before it is considered). Steam's disclosure form (changed
+2026-01-16) lists pre-generated 3D models as content that must be
+declared on the store page: the licence notice G3 writes into the GLB is
+what the studio answers that form from.
