Frequently Asked Questions about Hunyuan3D
What makes Hunyuan 3D-2.1 different from other 3D generators?
Hunyuan 3D-2.1 combines full open-source transparency with a physics-driven PBR pipeline, delivering higher realism than closed competitors while letting developers customize every layer. This flexibility sets Tencent Hunyuan3D apart.
Is Hunyuan 3D-2.1 really free for commercial use?
Yes. Tencent Hunyuan3D licenses Hunyuan3D-2.1 under permissive terms that allow commercial distribution of assets. Just keep the required attribution line: “Created with Hunyuan 3D-2.1.”
Which GPUs can run Hunyuan3D v2.1 efficiently?
An NVIDIA RTX 3080 with 12 GB VRAM handles most scenes. For ultra-high-detail jobs, Hunyuan 3D-2.1 scales up to RTX 4090 or multi-GPU servers without code changes.
Can I fine-tune Hunyuan 3D-2.1 on my own dataset?
Absolutely. The released training scripts let you retrain Tencent Hunyuan3D on proprietary images or CAD data, creating domain-specific versions of Hunyuan3D-2.1.
Does Hunyuan 3D-2.1 support multi-view inputs?
Yes. Activate the `max_num_view` flag to feed up to six photos, and Hunyuan3D v2.1 will fuse them into a single high-accuracy mesh with aligned PBR textures.
How realistic are the materials generated by Hunyuan3D-2.1?
The PBR synthesizer in Hunyuan 3D-2.1 models diffuse, metallic, roughness, and normal maps, capturing micro-details like leather grain or brushed aluminum.
Can I use Hunyuan 3D-2.1 assets in game engines?
Yes. Hunyuan3D-2.1 exports standard OBJ/FBX/GLB with embedded PBR maps, making Tencent Hunyuan3D assets drag-and-drop ready for Unity and Unreal.
Is there a web demo for Hunyuan3D-2.1?
Tencent Hunyuan3D hosts a Hugging Face Space where you can test Hunyuan 3D-2.1 in your browser. For heavier jobs, clone the repo locally.
How do I contribute to the Hunyuan3D community?
Fork the Hunyuan 3D-2.1 repo, submit pull requests, or share checkpoints. Tencent Hunyuan3D maintains an active Discord for idea exchange.
Where can I find benchmarks for Hunyuan 3D-2.1?
Official ULIP-T and CLIP-I scores are in the GitHub README. Independent reviewers consistently rank Hunyuan3D v2.1 at the top for geometry accuracy and texture fidelity.
