Text or Image In. 3D Model Out.
Production-Ready Textures
Generate models with metallic, roughness, and normal map textures that look realistic under any lighting conditions. Output is ready for game engines, AR/VR, and film production pipelines.
8 Angles, One Model
Provide up to 8 reference images including front, back, sides, top, bottom, and diagonal views. More angles mean more accurate geometry. Exclusive to v3.1 Pro.
Split, Retopologize, Ship
Split generated models into individual parts with the Part endpoint. Clean up mesh topology with Smart Retopology, choosing quad or triangle output and controlling polygon density. A full pipeline from prompt to production.

What can I create with Hunyuan 3D?
Hunyuan 3D v3.1 generates 3D models from text prompts or images. It outputs GLB and OBJ files with up to 1.5 million polygons, optional PBR materials (metallic, roughness, normal maps), and textured or geometry-only modes. Post-processing endpoints handle part splitting and smart retopology.
What is the difference between Pro and Rapid?
Pro endpoints ($0.375/generation) support longer prompts (up to 1,024 characters), custom polygon counts (40K to 1.5M faces), and multi-view image input with up to 8 angles. Rapid endpoints ($0.225/generation) are faster and cheaper with shorter prompts (200 characters) and fixed polygon output.
What are PBR materials?
PBR (Physically Based Rendering) materials include metallic, roughness, and normal map textures that make 3D models look realistic under any lighting. Enable PBR on any generation endpoint for an additional $0.15 per generation. The result is game-engine and production-ready.
How many images can I use as input?
The Pro image-to-3D endpoint accepts up to 8 view angles: front, back, left, right, top, bottom, and two 45-degree diagonal views. Top, bottom, and diagonal views are exclusive to v3.1. More views produce more accurate 3D reconstructions. Rapid image-to-3D accepts a single front view.
How much does Hunyuan 3D cost on fal.ai?
Pro text-to-3D and image-to-3D: $0.375/generation. Rapid variants: $0.225/generation. PBR materials add $0.15. Part splitting: $0.45/generation. Smart retopology: $0.75/generation. Pay-per-use with no minimums.
How do I get started with the API?
Install the fal.ai SDK (Python or JavaScript), grab an API key from your dashboard, and make your first request in a few lines of code. The API is serverless, so no GPUs to manage. Check the API documentation for all available parameters.
Can I use Hunyuan 3D for commercial projects?
Yes. Content generated through the fal.ai API can be used in commercial projects. Check fal.ai's terms of service for full details on usage rights and licensing.
