By the end, you’ll have the knowledge to create, refine, and iterate on 3D assets faster and better than ever before,while staying aware of the platform’s limitations and best practices.

Getting Started with Hunyuan 3D 2.5: Setup, Access, and Interface

Before you can generate your first AI-driven 3D model, you need to set up and access the Hunyuan 3D 2.5 platform. Here’s how to begin, even if you’re encountering a foreign-language platform or are entirely new to this space.

Platform Availability and Access
Hunyuan 3D 2.5 is currently accessed exclusively through its official website. There’s no desktop application or downloadable model weights for local use at this stage. All model generation takes place on their web platform.

Account Setup and Login Process
To use Hunyuan 3D 2.5, you’ll need to sign up with your email address. The platform uses a verification code system,enter your email, receive a code, and log in. The interface may be in Chinese, so it’s a good idea to have a browser-based translation tool handy (Google Chrome’s built-in translator works well).

Free Tier and Generation Limitations
The platform generously offers 20 free generations. If you invite friends, you can earn additional generation opportunities. This is ideal for testing and experimentation, but keep in mind that heavy or commercial use will require further arrangements.

Commercial Use Restrictions
Commercial use of Hunyuan 3D 2.5 output is not permitted by default. If you want to use generated assets for commercial projects, you must obtain a license from Tencent. For hobbyists and personal projects, the free tier is unrestricted; for freelancers or studios, factor in this limitation early on.

Interface Overview and Navigation
The interface, though straightforward, can be challenging due to language barriers. Most core features are available through clearly marked tabs: “True Shank 3D” for image-based generation, “Vincent 3D” for text-based generation, and “Laboratory” for advanced features. Use online translation if needed, and familiarize yourself with the layout,core actions like “Generate,” “Export,” and “Refresh” are usually in prominent locations.

Example 1: You sign up, log in with your code, and use Google Translate to navigate the site, starting a project in the “True Shank 3D” section.
Example 2: You invite a colleague, both gaining extra generation credits, and communicate with Tencent’s team to inquire about licensing for a commercial game project.

Core Generation Modes: Single Image, Multi-Image, and Text-to-3D

Hunyuan 3D 2.5 gives you three primary pathways to generate 3D models: from a single 2D image, from multiple 2D images (multi-view), and directly from a text prompt. Each method has its own strengths, best use cases, and necessary preparation steps.

Single Image Generation: From a Photo to a 3D Model

This is the quickest way to create a 3D model: upload a single image, and let Hunyuan 3D do the rest. Ideal for simple characters, concept art, or when you only have one view of your subject.

Workflow:

• Navigate to the “True Shank 3D” section.
• Upload your 2D image. JPEG format is strongly recommended, as PNGs can cause upload issues.
• Select version 2.5 for the best quality.
• Enable “Generate PBR Map” to get physically based rendering textures (albedo, normal maps).
• Start the generation. Processing typically takes around 7 minutes.
• Once complete, you can view the model in the “Asset” section and export it in formats like GB, OBJ, and FBX. GB format is preferred for preserving PBR textures.

Example 1: You upload a JPEG of a cartoon hero, select version 2.5, and after processing, download a detailed 3D model with color textures and normal maps.
Example 2: You use a JPEG of a product concept (like a sneaker) and quickly get a 3D preview with realistic surface detail for a presentation.

Tips and Best Practices:
- Always use high-resolution, clear images for the best results.
- JPEGs streamline the upload process and minimize errors.
- If you want to rig or animate your character later, try to use images where the subject is in a T-pose (arms outstretched horizontally).

Multi-Image Generation: Creating Accurate, Detailed Models from Multiple Angles

When accuracy and detail matter, use the multi-image mode. By uploading front, rear, left, and right views, you give the AI much more information,resulting in richer geometry and more faithfully reproduced features.

Workflow:

• In “True Shank 3D,” choose the multi-image option.
• Upload four images: front, rear, left, and right views of your subject.
• These images should be consistent in style, lighting, and pose. Tools like Midjourney (version 7) can help you generate such consistent multi-views (prompt for “front, left, right, back” and use an image editor to crop each angle).
• Proceed with generation as before, enabling PBR map output.
• Results will appear in your asset library, typically with greater fidelity,details from all sides are captured (e.g., backpacks, side features).

Example 1: You generate a set of four Midjourney images of a robot from all angles, crop them, upload, and produce a highly accurate 3D model that includes back-mounted equipment.
Example 2: A character with an intricate hairstyle or accessories (like a sword on the back) is fully captured because the rear and side views provide the missing information.

Tips and Best Practices:
- Multi-view input results in models that are more accurate, less ambiguous, and include features invisible in single views.
- Consistency is key: use the same style, pose, and lighting across all images.
- If you use AI tools like Midjourney, always check output for alignment and crop carefully to ensure each view matches up.

Comparison: Single Image vs. Multi-Image Generation

The difference between these modes is dramatic. Single-image generation is fast and convenient, but often results in “best guess” geometry for unseen areas. Multi-image generation fills in those gaps, producing models that are both more detailed and more accurate to your vision.

Example 1: In single image mode, a character’s backpack is missing; in multi-image mode, it’s accurately modeled.
Example 2: Single-view outputs have less pronounced side features (like earrings or helmets), while multi-view captures these fully.

Key Considerations:
- Use single image mode for speed, simplicity, or when only one angle is available.
- Use multi-image mode for characters, products, or props where full detail and accuracy are required.
- Multi-image requires more prep, but pays off with higher-quality output.

Text-to-3D Generation: Bringing Ideas to Life from Written Prompts

Hunyuan 3D 2.5 lets you skip the image step entirely. In the “Vincent 3D” section, you can generate detailed models from natural language descriptions. This is especially useful for ideation, rapid prototyping, or when no images exist.

Workflow:

• Navigate to “Vincent 3D.”
• Enter a detailed text prompt describing the subject, style, features, and desired texture style (e.g., “a futuristic armored knight, silver and blue, with glowing eyes and metallic textures”).
• Click “Generate.” The system will produce four different model options to choose from.
• Review and download your preferred model. The output includes geometry and textures, although some minor texture artifacts (e.g., on eyes) may occur.

Example 1: You prompt for “a small, chubby dragon with scales and big wings,” and receive four unique 3D dragon models, each with detailed textures.
Example 2: You describe “a rusty robot with red stripes and exposed gears,” and get several robot models that match the description, ready for download and further refinement.

Best Practices:
- Be as specific as possible in your text prompt: mention colors, materials, pose, and distinctive features.
- Review all four generated options,sometimes unexpected variations contain the best results.
- Use this mode for ideation, concept art, or unique objects where no reference images exist.

Advanced Input Methods: Sketch-to-3D and Generating Separate Parts

Beyond photos and text, Hunyuan 3D 2.5 offers powerful advanced input workflows,turning hand-drawn sketches into 3D models, and generating separate model parts for modular design.

Sketch-to-3D: Turning Drawings into 3D Models

The “SketchUp 3D” feature is more than a novelty,it’s a bridge between 2D creativity and 3D output. Upload a sketch (black and white or simple line art), optionally add a descriptive prompt, and let the system build both geometry and texture.

Workflow:

• Go to the “SketchUp 3D” section.
• Upload your sketch,clear, high-contrast black and white drawings work best.
• (Optional) Add a text prompt to clarify style, color, or material.
• Click “Generate.” The output delivers a fully formed 3D model, complete with basic textures.

Example 1: You sketch a cartoon cat, upload the image, and receive a 3D cat model with the same proportions and expressive features.
Example 2: You draw a spaceship silhouette, add the prompt “metallic, blue accents,” and get a 3D spaceship with appropriate texturing.

Tips:
- Use clean, high-contrast sketches for best results.
- Combine with the 3D texture feature (see below) to further refine your model’s look.
- This is perfect for doodles, character design, and quickly testing ideas before investing in detailed concept art.

Generating Separate Parts: Modular Character and Object Creation

Sometimes you want to build a character or object from modular pieces, not as a single mesh. Hunyuan 3D 2.5 enables this by generating individual parts from a “separate parts sheet.”

Workflow (using ChatGPT and Blender):

• Create or find an image containing the separate parts you want (e.g., a character sheet with arms, legs, head, accessories laid out).
• Optionally, use ChatGPT to help organize or label the parts sheet for clarity.
• Upload the parts sheet to Hunyuan 3D 2.5 in the relevant section.
• The system generates separate 3D models for each part.
• Download and import the parts into Blender.
• In Blender, use “merge by distance” to clean up vertices, and “separate by loose parts” to split the mesh into individual, movable components.

Example 1: You upload a character sheet with helmet, torso, arms, and legs, and Hunyuan creates individual 3D parts that you can assemble and pose in Blender.
Example 2: For a robot design, you upload a sheet with head, limbs, and gadgets, and build a customizable robot by combining or swapping parts in your 3D editor.

Tips and Best Practices:
- Organize your parts clearly in the input image.
- After import, always clean up geometry in Blender using “merge by distance” to eliminate duplicate vertices.
- Use “separate by loose parts” to make each component an independent object, giving you full control in assembly or animation.

Model Output: Exporting, File Formats, and Asset Management

Once your model is generated, getting it out of Hunyuan 3D 2.5 and into your favorite 3D software is crucial. The platform supports several export formats, each with its pros and cons.

Supported Export Formats:
- GB: Best for preserving PBR texture maps (albedo, normal).
- OBJ: Widely supported in all 3D software; may require manual texture setup.
- FBX: Ideal for animation workflows; supports rigged and animated models.

Example 1: You export a model as GB for use in Blender, retaining all PBR textures.
Example 2: You export as FBX to bring a rigged and animated character directly into Unity or Unreal Engine.

Tips:
- Choose GB for maximum fidelity if you want to work with textures out of the box.
- FBX is preferable for pipeline integration with animation and game engines.
- Always check the exported model’s scale and orientation; adjust in your 3D editor as needed.

Understanding and Fixing Topology: Triangulated Meshes and Retopology

One current limitation of Hunyuan 3D 2.5 is its topology: models are often highly triangulated and dense. While this preserves detail, it can make editing, animation, and real-time use more difficult. External tools are needed for retopology.

What Is the Issue?
- Generated models use dense, triangle-based geometry.
- No built-in retopology (automatic conversion to cleaner, quad-based topology) is available in Hunyuan 3D 2.5.
- High-density, triangulated meshes are heavier to edit and animate.

How to Fix It:

• Import your model into Blender or similar software.
• Use “merge by distance” to clean up overlapping or duplicate vertices.
• Use add-ons like “Quad Remesher” to convert triangles to quads and reduce mesh density.
• After retopology, check for lost detail and reproject normals or details as needed.

Example 1: You bring a dense, triangulated character mesh into Blender and use Quad Remesher for a cleaner, animation-friendly quad-based topology.
Example 2: You clean up a complex prop model by merging vertices and simplifying the mesh for use in a game engine.

Best Practices:
- For animation or game use, always retopologize dense AI-generated models.
- Use high-density meshes as “high poly” sources for baking detail onto new, clean “low poly” versions.

Rigging and Animation: Automatic Bone Binding and Animation Generation

Hunyuan 3D 2.5 enables basic rigging and animation directly on the platform, allowing you to bring static models to life with just a few clicks.

Requirements:
- The character model must be in a T-pose (arms stretched horizontally). This is essential for successful automatic rigging.
- Either upload an image of a character in T-pose, or specify this pose in your prompt if using text-to-3D.

Workflow:

• After generating your model, navigate to the “Laboratory” or animation section.
• Select the automatic bone binding feature.
• The system generates a skeletal rig and binds it to your model.
• Basic animations (e.g., standing, walking, jumping, falling) can be previewed and downloaded as part of the FBX export.

Example 1: You upload a T-posed superhero, run automatic bone binding, and download a model with standing and walking animations for use in a game prototype.
Example 2: You prompt for a T-posed robot in text-to-3D, rig it with a single click, and export it for animation refinement in Blender.

Best Practices:
- Always use T-pose images or prompts for characters you intend to rig.
- Simple, neutral poses result in cleaner bone assignment and easier animation.

Advanced Texture Generation: Retexturing Existing Models

Sometimes you want to give a fresh look to an existing model,whether generated by Hunyuan or imported from another source. The “Laboratory” section’s 3D texture generation feature enables you to create new textures using text prompts or reference images.

Workflow:

• Go to the “Laboratory” section.
• Upload your 3D model (can be one generated by Hunyuan or from another source).
• Choose to use the original UV map or generate a new one.
• Provide either a text prompt (e.g., “rusty robot with blue and red stripes”) or a reference image to guide the texture generation.
• Click “Generate.” The process takes about 70 seconds.
• Download the newly textured model for further use or refinement.

Example 1: You retexture a plain robot with a “steampunk copper and brass” prompt, instantly giving it a new visual identity.
Example 2: You import an external vehicle model, use a reference image of camouflage patterns, and generate a matching texture in seconds.

Best Practices:
- Choose “original UVs” for precise texture placement; use “new UVs” if your model’s UV packing is poor.
- Experiment with different prompts and references to achieve the desired style.

Integrating with Blender: Refining, Editing, and Retopologizing Models

Blender is the go-to tool for cleaning up, editing, and preparing Hunyuan 3D 2.5 models for animation or game use. Here’s how to get the most out of your AI-generated assets in Blender.

Importing Models:
- Import GB, OBJ, or FBX files exported from Hunyuan 3D.
- Check model scale, orientation, and texture connections.

Mesh Cleanup:
- Use “merge by distance” to eliminate duplicate vertices.
- Use “separate by loose parts” to split modular models into distinct objects.

Retopology:
- Apply Quad Remesher or Blender’s built-in retopology tools to convert dense, triangulated meshes into quad-based, animation-ready topology.

Pivot and Origin Management:
- Use “Set Origin to Geometry” to ensure each part’s pivot is at its center for proper rotation and scaling.

Example 1: You import a multi-part character, clean up the mesh, retopologize, and then rig for custom animations.
Example 2: You bring in a textured prop, optimize topology, and adjust UVs for game engine import.

Tips:
- Always check normals and texture assignments after import.
- Use Blender’s viewport to preview PBR textures and make adjustments before exporting to your final destination.

Comfy UI Integration: Advanced and Precise Texture Workflows

For users familiar with node-based workflows (like Stable Diffusion), integrating Hunyuan 3D models with Comfy UI enables even more precise texture generation and style transfer. This workflow is more advanced, but extremely powerful for artists who want tight control.

Workflow:

• Download your 3D model from Hunyuan 3D 2.5.
• In Comfy UI, use a “hunan free load mesh” node to load your model.
• Add a “Hunion 3D render multiview” node to render the model from multiple angles.
• Use text prompts or reference images for texture generation, leveraging the node-based flexibility of Comfy UI for precise results.

Example 1: You load a character model and use Comfy UI’s workflow to generate a photorealistic skin texture based on a specific portrait reference.
Example 2: You apply a series of texture variations by chaining nodes, allowing for rapid iteration and side-by-side comparison.

Tips:
- This workflow is best for users comfortable with node-based systems.
- Use it when you need higher fidelity, more artistic control, or specific style matching.

What should I do if my generated model has mesh errors or artifacts?

Use Blender’s "Merge by Distance" to fix overlapping vertices, and "Separate by Loose Parts" to organize disconnected geometry.
Mesh cleanup is a standard part of the workflow and ensures models are ready for animation or further editing. If problems persist, consider regenerating with improved input images or prompts.

Can I generate vehicles or non-humanoid objects in Hunyuan 3D 2.5?

Yes, both humanoid and non-humanoid models (like vehicles, props, or furniture) can be generated.
For best results, provide multi-view images or detailed text prompts describing the object’s features and style. This versatility makes Hunyuan 3D 2.5 suitable for a wide range of creative and industrial applications.

Can I reuse a model for multiple projects with different textures?

Absolutely. The 3D Texture Generation feature lets you apply new textures to an existing model using text prompts or reference images.
This is ideal for creating product variants or adapting a character to different game levels without redoing the base mesh.

How can I improve the quality of generated models?

Use high-resolution, clear images with consistent lighting for input.
Multi-view image sets help the AI capture more detail. For text-based generation, be specific in your descriptions. Post-process in Blender or similar software for mesh cleanup and refinement.

What are the best practices for preparing input images?

Use JPEG format, ensure neutral backgrounds, even lighting, and minimal occlusions.
For multi-view generation, crop and align each angle carefully. Consistency across input images results in higher-quality, more accurate 3D models.

Can I run Hunyuan 3D 2.5 locally or integrate it into other workflows?

Currently, Hunyuan 3D 2.5 is only accessible via its web platform.
There are no downloadable model weights or APIs for local or automated integration. However, exported models and textures can be used in your preferred 3D pipeline after download.

Is there language support for non-Chinese users?

The interface is primarily in Chinese, but browser translation extensions (such as Google Translate) make it usable for non-Chinese speakers.
It’s helpful to keep a translation tool active for navigating options and understanding error messages.

Are there any privacy or data security considerations?

Can I generate 3D models of people or real-life objects?

Yes, Hunyuan 3D 2.5 works well for generating stylized or realistic models of people, animals, objects, or even abstract concepts, as long as you provide good input images or detailed text prompts.
For photorealistic results, ensure your source material is high quality and properly aligned for multi-view generation.

What happens if my input image or prompt is low quality?

Poor input (blurry images, vague descriptions) leads to incomplete or inaccurate 3D models.
The output may have missing features, distorted geometry, or mismatched textures. For best results, use high-quality images and specific, descriptive text prompts.

Can I use Hunyuan 3D 2.5 to create assets for VR, AR, or 3D printing?

Yes, exported models can be refined and repurposed for VR, AR, or even 3D printing, after appropriate post-processing (e.g., retopology, watertight mesh fixes).
For 3D printing, ensure the model is manifold and scaled correctly in your 3D software.

Does Hunyuan 3D 2.5 support UV mapping?

Yes, generated models include UV maps suitable for texture application.
However, complex shapes may require manual adjustment in external software for optimal texture alignment, especially if you plan to use custom or high-resolution textures.

What are some common pitfalls to avoid when using Hunyuan 3D 2.5?

Avoid using low-resolution or cluttered images, skipping mesh cleanup, or neglecting to check licensing terms for commercial work.
Careful preparation and post-processing save time and prevent issues down the line, especially for professional projects.

Is there an API or automation option for batch processing?

No public API or batch automation is available at this time.
All generations must be done manually through the website interface. For larger projects, plan accordingly and consider how the generation quota may limit your workflow.
