Question 1

What can I make with Hunyuan 3D 3.1?

Accepted Answer

Anything that starts as a prompt or a single image and ends as a 3D mesh. Generate game props, weapons, characters, vehicles, and environment pieces. Turn a concept sketch into a base mesh for sculpting. Build blockouts for a level or a previs scene. Produce assets for AR, VR, and real-time engines. Make printable models for resin and FDM workflows. The output is a clean GLB you can drop straight into Blender, Unity, or Unreal.

Question 2

Should I use a text prompt or a reference image?

Accepted Answer

A reference image almost always wins. Hunyuan 3D 3.1 follows the silhouette, the proportions, and the details of an image far more tightly than a text description. Text prompts work for simple shapes and quick exploration. For characters, products, and anything with a specific look, generate or upload an image first, then turn it into a mesh. Visual Sandbox lets you do both steps in the same project.

Question 3

How good is the mesh quality and topology?

Accepted Answer

Hunyuan 3D 3.1 produces dense triangle meshes that hold up at viewport distance and in renders. Topology is not yet hand-crafted quad flow, so for animation or high-end production you will want a retopology pass in Blender, ZBrush, or your tool of choice. For static props, prototypes, previs, and 3D printing, the raw mesh is usually ready to use. Detail scales with the face count, and the default of 500k faces is a strong balance between fidelity and file size.

Question 4

What file format does Hunyuan 3D 3.1 export?

Accepted Answer

GLB. It is the binary glTF format and it is the most portable 3D container in use today. GLB carries the mesh, the UVs, and the textures in a single file. Visual Sandbox lets you preview the result in the browser and download the GLB in one click. Convert to FBX, OBJ, USD, or STL inside Blender or any standard DCC tool when your pipeline needs a different format.

Question 5

How do I import the model into Blender, Unity, or Unreal?

Accepted Answer

All three import GLB natively. In Blender, use File then Import then glTF 2.0 and pick the GLB. In Unity, drag the GLB into your Assets folder with the glTFast package installed. In Unreal, use the glTF Importer plugin or convert to FBX first for tighter material control. The mesh, the UVs, and the base textures come across in a single step.

Question 6

Does Hunyuan 3D 3.1 generate PBR materials and textures?

Accepted Answer

Yes. The model produces a textured mesh with a base color map, and PBR generation is supported under the hood for materials that respond to physically based lighting. Visual Sandbox runs Hunyuan 3D 3.1 with production-ready defaults so the GLB you download lights correctly in Blender, Unity, and Unreal without extra setup.

Question 7

How does Hunyuan 3D 3.1 compare to other AI 3D tools?

Accepted Answer

Hunyuan 3D 3.1 is one of the strongest open foundation models for image-to-3D and text-to-3D today. It is Tencent's flagship in this space and sits alongside tools like Tripo, Trellis, Meshy, and Rodin in the wider 3D AI landscape. Each has its own strengths in topology, texture quality, and style. Visual Sandbox exposes Hunyuan 3D 3.1 as a clean, no-setup way to use it. There is no GPU to provision, no ComfyUI graph to wire up, and no install to maintain.

Question 8

How much does a Hunyuan 3D 3.1 generation cost?

Accepted Answer

About twenty cents per generation. Visual Sandbox shows the exact cost before you generate, and charges per generation when the GLB is delivered. There is no subscription, no monthly minimum, and no credit pack to top up. Whether you make one mesh or fifty, the cost stays the same per generation.

Question 9

How long does a generation take?

Accepted Answer

Usually one to two minutes per mesh, depending on the complexity of the input. Images with a clean background and a clear single subject finish fastest. Complex scenes and very high face counts take a little longer. Visual Sandbox handles the heavy lifting in the cloud, so you do not need a local GPU to get fast turnaround.

Question 10

Can I use Hunyuan 3D 3.1 meshes commercially?

Accepted Answer

Yes. Tencent's Hunyuan 3D license permits commercial use of generated meshes for the vast majority of creators and studios. You are responsible for the input and the final use, especially when the source image involves a real person, a brand, or copyrighted material. The model is widely used for indie games, client work, 3D printing storefronts, and previsualization on Visual Sandbox.
