Tencent has released Hunyuan 3D 2.1, an open-source model for generating 3D assets, including PBR materials. This model can synthesize objects with cinematic textures and realistic light interactions.
- Tencent Hunyuan3D-2.1 is a scalable 3D asset creation system.
- It advances state-of-the-art 3D generation through two innovations: Fully Open-Source Framework and Physically-Based Rendering (PBR) Texture Synthesis.
- The system releases full model weights and training code, enabling community developers to directly fine-tune and extend the model for diverse downstream applications.
- This transparency accelerates academic research and industrial deployment.
- The upgraded PBR pipeline leverages physics-grounded material simulation to generate textures with photorealistic light interaction.
- The system replaces the prior RGB-based texture model with the upgraded PBR pipeline.
