What is Hunyuan3D-2?
Hunyuan3D-2 is an advanced large-scale 3D synthesis system designed for generating high-resolution textured 3D assets. It represents a significant advancement in the field of 3D content generation, utilizing a two-stage pipeline that separates shape generation from texture synthesis. The system employs two foundation components: Hunyuan3D-DiT for shape generation and Hunyuan3D-Paint for texture synthesis.
Implementation Details
The model architecture consists of a flow-based diffusion transformer for shape generation and a specialized texture synthesis model. The shape generation component creates geometry that aligns with condition images, while the texture synthesis model produces high-resolution texture maps for both generated and hand-crafted meshes.
