The Technical Architecture of Hunyuan 3D

Tencent Hunyuan 3D operates on an advanced and efficient two-stage generation pipeline. This approach decouples the complex challenges of shape generation and texture synthesis, providing both high-quality results and flexibility.

1. Stage 1: Shape Generation (Hunyuan3D-DiT): The process begins with a large-scale shape generation model named Hunyuan3D-DiT. This model, built on a scalable flow-based diffusion transformer, is responsible for creating the core geometry. It is designed to properly align the 3D shape with a given condition, whether it’s a text prompt, a single image, or multi-view images. This lays a solid foundation for all downstream applications.
2. Stage 2: Texture Synthesis (Hunyuan3D-Paint): Once the bare mesh is created, a large-scale texture synthesis model, Hunyuan3D-Paint, takes over. It leverages strong geometric and diffusion priors to generate high-resolution, vibrant texture maps. This model can texture meshes generated by the first stage or even hand-crafted meshes you upload, offering versatility in your workflow. The latest version of this generative AI tool has been upgraded to support PBR materials through a new multi-view architecture.

This two-stage strategy is what allows Hunyuan 3D to excel in both geometry detail and texture quality, outperforming many other methods in the field of 3D model generation.
