TENCENT(HK:00700) Guang Zhou Ri Bao·2025-06-14 14:17Core Viewpoint - Tencent's Mix Yuan 3D model has undergone a significant upgrade with the release of version 2.1, which is the first fully open-source industrial-grade 3D generation model, achieving industry-leading standards [2]. Group 1: Model Features and Performance - The Mix Yuan 3D model has surpassed 1.8 million downloads on Hugging Face, indicating its popularity and utility in the open-source community [2]. - The new version 2.1 has improved geometric generation quality and introduced PBR (Physically Based Rendering) material generation, enhancing the texture and lighting effects of 3D assets, moving away from a "plastic feel" [6][8]. - In user blind tests, the PBR textures of the Mix Yuan 3D 2.1 model outperformed RGB textures with a quality superiority rate of 78% [8]. Group 2: Accessibility and Customization - The Mix Yuan 3D 2.1 model has lowered development barriers by providing a fully open-source solution, including model weights, training code, and data processing workflows, allowing developers to fine-tune, retrain, or optimize the model for various customization needs [8]. - The model is compatible with consumer-grade graphics cards, enabling it to run on personal computers, thus broadening its accessibility for developers and researchers [8]. Group 3: Technical Enhancements - The new model optimizes detail modeling, resulting in higher mesh precision and better topological consistency, which lays the groundwork for subsequent texture mapping [8]. - It supports the generation of base color, metallicity, normal, and roughness maps, allowing for high-quality rendering of various complex materials such as leather, wood, metal, and ceramics [8].
