At its core, Hunyuan 3D 2.0 utilizes a sophisticated two-stage generation pipeline. The first stage involves the creation of high-quality bare meshes, which is handled by the large-scale shape generation model called Hunyuan3D-DiT. This component is built on a scalable flow-based diffusion transformer, capable of producing geometries that align precisely with given condition images. The second stage focuses on synthesizing detailed texture maps, which is managed by the large-scale texture synthesis model known as Hunyuan3D-Paint. This model leverages powerful geometric and diffusion priors to generate high-resolution, vivid texture maps for both AI-generated and hand-crafted meshes.
One of the most impressive aspects of Hunyuan 3D 2.0 is its ability to generate complete 3D models from various inputs, including text descriptions, reference images, black and white line sketches, and even portrait photos. This versatility makes it an invaluable tool for a wide range of applications, from game development and e-commerce to entertainment and virtual reality.
The system's capabilities extend beyond mere model generation. Hunyuan 3D 2.0 also offers a comprehensive set of tools for 3D asset manipulation and enhancement. Users can take advantage of features like automatic skeleton binding for models, a rich library of animation presets, and direct animation preview for humanoid and animal models. The platform also supports the generation of low-polygon models with customizable optimization intensity, making it particularly useful for game developers looking to reduce computational demands on hardware.
Tencent has also developed Hunyuan3D-Studio, a user-friendly production platform that provides a seamless experience for editing, animating, and exporting 3D assets. This web-based toolkit allows users to convert sketches to 3D models, simplify complex designs, and animate characters, although access requires logging in.
