Tencent Releases Hunyuan3D 2.0: Open-Source High-Quality 3D Generation Model and End-to-End Creation Engine

Tencent Hunyuan3D

Tencent recently released Hunyuan3D 2.0, the industry’s first fully open-source high-quality 3D-DiT (Diffusion Transformer) generation model. The new version introduces an innovative two-stage generation pipeline: first generating high-quality bare meshes, then synthesizing detailed texture maps. This strategy effectively separates the complexity of shape and texture generation while providing greater flexibility for subsequent customization.

Core Technical Breakthroughs

Hunyuan3D 2.0 consists of two fundamental components:

  • Large-scale Shape Generation Model (Hunyuan3D-DiT): Built on a scalable flow-based diffusion transformer, capable of creating geometries precisely aligned with given condition images
  • Large-scale Texture Synthesis Model (Hunyuan3D-Paint): Utilizing powerful geometric and diffusion priors to generate high-resolution, vivid texture maps for both generated and hand-crafted meshes
