Hunyuan3D

Hunyuan3D is Tencent's open-source system for generating high-fidelity 3D assets from reference images. Hunyuan3D 2.1 separates shape generation from texture synthesis and produces physically based rendering (PBR) materials suitable for game, visualization, and digital-content pipelines.

Key features

• Image-to-3D shape generation with detailed geometry
• Dedicated PBR texture synthesis model
• Open model weights and source code
• Diffusers-style Python pipelines for shape and paint stages
• Runs locally on Windows, macOS, and Linux with supported hardware

It is a strong option for researchers and studios that need an open, self-hostable alternative to commercial 3D asset generators.
