What happens if my model has more than 30,000 faces?

Models exceeding 30,000 faces will not be processed and you'll receive an error notification before any credits are charged. To work with larger models, use your 3D software's decimation or simplification tools to reduce polygon count below the threshold. Alternatively, process the model through <a href="/model/hunyuan-3-1-smart-topology-3d">Hunyuan 3.1 Smart Topology 3D</a> first, which can optimize and reduce face count while maintaining visual quality. Most AI-generated models from <a href="/model/meshy-v6-text-to-3d">Meshy v6</a> or Hunyuan generators stay well under this limit, but manually sculpted or scanned models may require optimization before splitting.

💡 Pro Tips for Hunyuan 3.1 Part Splitter 3D

★

Pre-Optimize Your FBX Before Upload Before splitting, ensure your FBX file is under 30,000 faces and 100MB. Use your 3D software's decimation tools to reduce polygon count if needed. Models generated by Hunyuan 3.1 Rapid Text to 3D or Meshy v6 Text to 3D typically fall within these limits automatically. Clean geometry splits faster and more accurately than models with overlapping faces or non-manifold edges.

★

Combine with Topology Tools for Clean Results After splitting your model into parts, run each component through Hunyuan 3.1 Smart Topology 3D to optimize mesh flow and reduce triangle count. This two-step workflow produces modular assets that are both cleanly separated and performance-optimized for real-time rendering in game engines or AR/VR applications. The combination saves hours of manual retopology work while maintaining professional-grade asset quality.

★

Use URL Input for Cloud-Based Workflows If your FBX files are already hosted on cloud storage or generated by another JAI Portal model, use the URL input option instead of uploading files directly. This eliminates download/upload time and creates a seamless pipeline. For example, generate a model with Hunyuan 3.1 Pro Image to 3D, then pass its output URL directly to the Part Splitter for immediate component separation without manual file handling.

★

Verify Part Separation Before Animation Always inspect the split parts in your 3D software before rigging or animating. The Part Splitter intelligently detects logical separations, but complex geometries may require manual adjustment. Check that joints, overlapping elements, and connected components are split as expected. This verification step prevents animation issues downstream and ensures each part can be independently manipulated or textured without artifacts.

★

Batch Process Multiple Models Efficiently If you have multiple AI-generated models to split, process them sequentially using the URL input method. Generate your assets with Meshy v6 Image to 3D or similar tools, collect the output URLs, then feed them to the Part Splitter one after another. With 15-30 second processing times, you can prepare dozens of modular assets in minutes rather than hours of manual work.

★

Keep Original Files for Reference Always retain your original unsplit FBX files alongside the separated parts. The Part Splitter creates new component files but doesn't modify your source. Having both versions allows you to compare results, reprocess with different settings if needed, or use the full model for contexts where separated parts aren't required. This redundancy is especially valuable for client deliverables or archival purposes.

Contact JAI Portal support for API documentation and integration assistance.

The Part Splitter focuses on geometric separation and preserves basic material assignments and UV coordinates where possible, but complex material setups may require reassignment after splitting. Each separated part retains its original UV mapping, allowing you to apply textures without remapping. However, if your FBX has multiple materials or complex shader networks, you may need to verify material assignments in your 3D software after splitting. For best results, apply detailed materials and textures after splitting rather than before. This workflow ensures clean material organization and prevents conflicts between separated components.
