Hunyuan3D-2 utilizes an innovative dual-model architecture to ensure the quality and integrity of 3D model generation. One of them, Hunyuan3D-DiT, serves as a shape generation model that focuses on building accurate base geometry. The model employs diffusion transformer technology to generate 3D meshes with the correct topology based on input text or images. It is capable of generating fine geometric models with up to 300k faces in tests.
Hunyuan3D-Paint, on the other hand, is a specially designed texture generation model capable of adding high-precision (2048×2048 resolution) color and material mapping to the surface of geometric models. The two models work in tandem, with the former generating shapes and the latter adding textures, to form a complete 3D asset generation solution. This modular design also allows users to use a component individually, increasing the flexibility of the tool.
