What is Hunyuan 3D?

Hunyuan 3D is Tencent's family of AI 3D generators. Kenerate AI's 3D Studio runs Hunyuan 3D 3.1 in its hosted Rapid edition, the studio's fastest engine: one front-view photo or a prompt of up to 200 characters becomes an untextured GLB in about a minute, made for drafts and blockouts. Version 3.1 was released in January 2026.

Shapes to draft with Hunyuan 3D

Simple, clear forms — ideal for fast, untextured drafts and blockouts.

Reference images made with Seedream 5.0 Pro. “To 3D” opens Image to 3D in the 3D Studio with that picture.

Why Kenerate

When Hunyuan 3D is the right engine

Speed and shape first, textures later.

  • An untextured clay 3D fox appearing quickly with speed streaks

    Drafts in about a minute

    Try several shapes quickly — a simple draft can take under half a minute — then rebuild the best on Tripo, Meshy or Rodin.

    Try it
  • A brass compass model, half wireframe and half textured

    Clean clay geometry

    The Rapid edition returns geometry only — no textures — which is exactly what you want for blockouts, sculpt bases and print tests.

    Try it

Also

What else it does

  • No settings to tune

    One photo or a short prompt in, a mesh out.

  • Good for printing

    Untextured meshes go straight to GLB to STL for a quick print.

How it works

How a Hunyuan job runs

Short and simple.

  • Input

    One clean, front-on photo, or a short description.

  • Shape

    Hunyuan's shape model builds a closed mesh.

  • No texture

    The Rapid edition skips texturing — you get clean clay geometry.

  • Deliver

    A GLB lands in your gallery in about a minute.

Illustrative examples of typical workflows, not customer reviews.

  • Grey clay 3D blockout of a game level with arches, crates and stairs

    Level designer

    A level designer could block out a scene with quick clay pieces, then rebuild the keepers on a textured engine.

  • Monitor showing a grey clay dragon head sculpt next to a graphics tablet

    Digital sculptor

    A sculptor could start from a clean untextured mesh as a sculpt base instead of a blank sphere.

  • Grey 3D printed armchair miniature on a printer bed

    3D printing hobbyist

    A maker could check size and shape with a fast draft, convert the GLB to STL and run a quick test print.

FAQ

Hunyuan 3D Generator questions

What is Hunyuan 3D?

Hunyuan 3D (Hunyuan3D) is Tencent's family of AI 3D generation models, with releases from 1.0 in 2024 to 3.x in 2025–2026.

Link to this answer

Which version does Kenerate use?

Hunyuan 3D 3.1 in its hosted Rapid edition — fast, geometry-only output. Tencent also offers other editions and has listed a newer 3.5 line.

Link to this answer

Is Hunyuan 3D open source?

Partly. Tencent published open weights up to Hunyuan3D 2.1 (June 2025) under the Tencent Hunyuan 3D 2.1 Community License. Versions 2.5, 3.0 and 3.1 are hosted services, not open weights.

Link to this answer

What does the open-source licence restrict?

The 2.1 community licence doesn't apply in the EU, UK or South Korea, requires a separate licence above 1 million monthly users, and forbids using outputs to improve other AI models. It covers the open weights, not the hosted 3.1 engine.

Link to this answer

Why is my model grey?

The Rapid edition returns geometry only. Rebuild on a textured engine for colour.

Link to this answer

Can I find Hunyuan 3D on Hugging Face?

The open 2.x weights are on Hugging Face; to use 3.1 without setup, run it in the 3D Studio.

Link to this answer

Can I use a Hunyuan 3D model in Blender?

Yes. Download the GLB and import it with File → Import → glTF 2.0. The Rapid edition's mesh is untextured clay, which suits sculpting, blockouts and print tests; rebuild it on Tripo, Meshy or Rodin if you need colour. Apply scale after import, since glTF uses metres.

Link to this answer

Do I need a Tencent account?

No — Hunyuan 3D runs inside Kenerate's 3D Studio on any paid plan or credit pack.

Timeline

Hunyuan3D 2.1 was open-sourced in June 2025 [28]. Version 3.0 was unveiled in September 2025 together with Professional and Rapid editions of the cloud API; 3.1 followed in January 2026 with better fidelity and multi-view input on the Professional edition [30]. Tencent has since listed a 3.5 line.
