Hunyuan3D-2.1 by Tencent is an open-source AI model designed to generate high-fidelity 3D assets with physically-based rendering (PBR) textures from images. Fully production-ready, it runs efficiently on consumer GPUs, making it accessible for both developers and researchers. The system stands out with two key innovations: a completely open-source framework and advanced PBR texture synthesis, enabling photorealistic material details like metallic reflections and subsurface scattering. The model outperforms existing 3D generation methods in asset quality and condition-following ability. It supports multiple operating systems and offers a user-friendly diffusers-like API for seamless integration. With full model weights and training code released, Hunyuan3D-2.1 encourages community-driven improvements and diverse applications. Its balance of performance, accessibility, and realism makes it a valuable tool for industries ranging from gaming to virtual production.
