Abstract: We present Hunyuan3D 2.0, an advanced large-scale 3D synthesis system for
generating high-resolution textured 3D assets. This system includes two
foundation components: a large-scale shape generation model -- Hunyuan3D-DiT,
and a large-scale texture synthesis model -- Hunyuan3D-Paint. The shape
generative model, built on a scalable flow-based diffusion transformer, aims to
create geometry that properly aligns with a given condition image, laying a
solid foundation for downstream applications. The texture synthesis model,
benefiting from strong geometric and diffusion priors, produces high-resolution
and vibrant texture maps for either generated or hand-crafted meshes.
Furthermore, we build Hunyuan3D-Studio -- a versatile, user-friendly production
platform that simplifies the re-creation process of 3D assets. It allows both
professional and amateur users to manipulate or even animate their meshes
efficiently. We systematically evaluate our models, showing that Hunyuan3D 2.0
outperforms previous state-of-the-art models, including the open-source models
and closed-source models in geometry details, condition alignment, texture
quality, and etc. Hunyuan3D 2.0 is publicly released in order to fill the gaps
in the open-source 3D community for large-scale foundation generative models.
