💡 Pro Tips for Hunyuan 3.1 Smart Topology 3D

★

Start with Clean Single Meshes Hunyuan 3.1 Smart Topology performs best on single, manifold meshes without overlapping geometry or loose vertices. Before uploading, merge separate objects in your 3D software and remove any internal faces or duplicate vertices. If your model has multiple parts, consider using Hunyuan 3.1 Part Splitter 3D first to isolate components, then optimize each individually for maximum control and cleaner topology.

★

Choose Quad Topology for Animation If your optimized model will be rigged or animated, select the quadrilateral polygon type instead of triangles. Quad-based meshes deform more naturally around joints and curved surfaces, reducing artifacts during animation. Triangle topology works best for static assets, game engines that auto-triangulate on import, or when maximum compatibility is required. For models generated via Hunyuan 3.1 Pro Text to 3D, quad output often pairs well with subsequent rigging workflows.

★

Match Density Level to Use Case High polygon density preserves fine details and is ideal for close-up renders or hero assets. Medium density balances quality and performance for most game and AR applications. Low density dramatically reduces file size and polygon count, perfect for mobile games, background props, or web viewers with strict performance budgets. Test each level with your target platform to find the sweet spot between visual fidelity and real-time rendering speed.

★

Optimize After Initial 3D Generation Models created with Meshy v6 Text to 3D or Hunyuan 3.1 Rapid Image to 3D often produce high-poly meshes with irregular topology. Running them through Smart Topology as a second step creates cleaner, production-ready assets with consistent edge flow. This two-stage workflow is especially valuable for game development pipelines where optimized geometry directly impacts frame rates and load times across devices.

★

Prepare Models for 3D Printing Before sending models to a 3D printer, use Smart Topology to ensure manifold geometry with no holes, flipped normals, or non-manifold edges. Select triangle topology and medium or high density to maintain printable detail. The optimized mesh will slice more reliably in slicer software and reduce the risk of print failures. Always verify the output in a mesh repair tool before final export to STL or OBJ format.

★

Batch Optimize Asset Libraries Efficiently If you manage large 3D asset collections, batch processing via API can save hours of manual work. Upload multiple high-poly models programmatically, apply consistent optimization settings, and receive clean meshes at scale. This approach is ideal for studios preparing asset packs, updating legacy content, or converting scan data into game-ready models. Combine with Hunyuan Motion Fast for animated asset pipelines that require both topology and motion optimization.

Frequently Asked Questions

The model supports GLB and OBJ file formats, which are widely used in 3D creation and production pipelines. Simply upload your file or provide a URL to get started.

You can upload files up to 200MB in size. This allows for optimization of complex, high-poly models while ensuring fast processing and manageable output.

Yes, you can select between triangle-only or mixed quad/triangle meshes, and adjust the polygon density to high, medium, or low. This gives you control over the balance between detail and performance.

Pricing varies by model and is based on a pay-as-you-go credit system. You only pay for what you use, making it flexible for different project needs.

AI-powered mesh optimization saves significant manual work, ensures consistent quality, and quickly produces lightweight models suitable for a wide range of applications such as games, AR/VR, and web experiences.

Hunyuan 3.1 Smart Topology 3D operates on JAI Portal's pay-as-you-go credit system, meaning you only pay for the optimizations you run. Pricing depends on the complexity and size of your input file, with typical optimizations consuming a modest number of credits per model. Unlike subscription-based tools, you never pay for unused capacity, making it cost-effective for freelancers, small studios, and enterprises alike. Check the current credit cost on the model page before running your optimization, and monitor your balance in your account dashboard. For high-volume workflows, purchasing credit bundles offers better per-unit pricing.

Yes, all 3D models optimized through Hunyuan 3.1 Smart Topology on JAI Portal are fully licensed for commercial use once you've paid the associated credits. You retain full ownership and can integrate the optimized meshes into games, apps, films, AR/VR experiences, client projects, or any commercial product without additional royalties or attribution requirements. This applies whether you're optimizing models you created yourself or assets generated via other JAI Portal models like Meshy v6 Image to 3D. Always ensure your input files respect third-party IP rights before optimization.

If the output mesh is missing fine details or surface features, try increasing the face level setting from medium to high. High density preserves more polygons and captures intricate geometry, though it results in larger file sizes. Alternatively, ensure your input model has sufficient polygon density in the areas you want to preserve—extremely low-poly source files may not have enough data for the AI to retain detail. For highly detailed sculpts or scans, consider running a test optimization at each density level to compare results. If you need even more control, pair Smart Topology with manual retopology in your 3D software for hybrid workflows.

Hunyuan 3.1 Smart Topology focuses on mesh geometry optimization and does not automatically transfer or regenerate UV maps or textures. If your input GLB or OBJ file includes UV coordinates and textures, they may not align perfectly with the optimized mesh due to changes in vertex count and topology. For textured models, you'll typically need to re-unwrap UVs and re-bake textures in your 3D software after optimization. This workflow is standard in production pipelines where topology and texturing are treated as separate stages. For best results, optimize geometry first, then apply textures to the clean mesh.

Yes, JAI Portal provides API access to Hunyuan 3.1 Smart Topology, allowing you to integrate mesh optimization into automated pipelines, batch processing scripts, or custom tools. This is ideal for studios managing large asset libraries, processing scan data at scale, or building end-to-end 3D content generation systems. You can programmatically upload models, specify optimization parameters, and retrieve optimized outputs without manual intervention. API usage follows the same credit-based pricing model, and you can monitor usage and costs via your account dashboard. Consult JAI Portal's API documentation for authentication, endpoint details, and code examples to get started.

⚖️ How Hunyuan 3.1 Smart Topology 3D Compares

Hunyuan 3.1 Smart Topology 3D is a specialized mesh optimization tool, distinct from JAI Portal's 3D generation models. While Meshy v6 Text to 3D, Hunyuan 3.1 Rapid Text to 3D, and Hunyuan 3.1 Pro Image to 3D create new 3D assets from prompts or images, Smart Topology refines existing high-poly models into efficient, production-ready meshes. If you already have a 3D model—whether sculpted, scanned, or generated by another tool—and need to reduce polygon count, clean up topology, or prepare it for real-time rendering, Smart Topology is your go-to solution. It complements generation models by serving as a post-processing step, ensuring your assets meet performance and compatibility requirements. For projects requiring both generation and optimization, consider pairing Hunyuan 3.1 Pro Text to 3D with Smart Topology for a complete end-to-end workflow. If your model has multiple separate parts, run Hunyuan 3.1 Part Splitter 3D first to isolate components, then optimize each individually. Smart Topology excels when you need granular control over polygon type and density, making it ideal for game developers, animators, and technical artists who demand clean, efficient geometry.
