Download Hunyuan3D Workflow

Key Inputs

Image: Use any JPG or PNG. Load the image you want to generate a 3D asset from, if it has a background this workflow will remove it and center the subject.
Prompt: as descriptive a prompt as possible
Denoise: The amount of variance in the new image. Higher has more variance.

What is Hunyuan 3D?

Hunyuan3D 2.0 is Tencent’s open-source Image-to-3D model. You feed it a 2D image, and it spits out a 3D mesh with textures. Simple idea, but under the hood, it's doing some heavy lifting.

It works in two steps:
1️⃣ Shape Generation (Hunyuan3D-DiT) – Creates a rough 3D structure based on the image.
2️⃣ Texture Synthesis (Hunyuan3D-Paint) – Adds realistic textures to the mesh.

This approach is flexible—you can generate a full 3D model from scratch or just apply textures to an existing mesh. That means it's useful whether you’re an AI artist, game developer, or just someone messing around with 3D assets.

What’s Cool About It?

✔️ Beats most open-source & some closed-source models in quality.
✔️ Runs on consumer GPUs (but you’ll need at least 11.5GB VRAM for shape generation, 24.5GB for both).
✔️ Supports Blender & Gradio, so you can integrate it into your workflow.
✔️ Works with ComfyUI (there’s a community-built wrapper).
✔️ Can generate realistic textures without weird artifacts.

Where It’s Tricky

• VRAM-hungry – If you’re on a low-end GPU, this will be slow or might not run at all.
• Not always plug & play – Expect some trial and error when fine-tuning models.
• Windows setup can be messy – There’s a community-built installer, but it's not officially supported.

What You’ll Need

• GPU with at least 11.5GB VRAM (24.5GB if you're doing full shape + texture).
• Python setup if you’re running it locally.
• Some patience—it’s not instant, and the results can vary.

Or you can use Hunyuan 3D with ThinkDiffusion cloud, without any installations or robust local config.

FAQs

1. Do I need a high-end GPU?
Yes, at least 11.5GB VRAM for shape generation and 24.5GB for shape + texture. RTX 3090+ recommended. Or you can use this on ThinkDiffusion cloud.

2. Can I use my own 3D models?
Yes! You can apply Hunyuan’s texture generation to existing meshes.

3. Is there a Windows version?
Sort of. The community built a Windows installer, but official support is Linux-first.

4. How does it compare to closed-source tools?
It’s close. Hunyuan outperforms many open-source models and competes with commercial tools. But closed models still have the edge in some cases.

5. Is there a UI, or do I have to use code?
Both. You can use Gradio (web UI), Blender, or run it via code/API.

6. Can I run this on ComfyUI?
Yes! The community built a ComfyUI-Hunyuan3DWrapper.

7. Does it generate animations?
Not yet. But you can export the models and animate them elsewhere.

8. What format are the 3D models in?
You get GLB/OBJ output, which works in Blender, Unreal, Unity, etc.
