腾讯混元推出业界首个美术级3D生成大模型Hunyuan3D-PolyGen
7月7日，腾讯混元3D团队宣布推出业界首个美术级3D生成大模型Hunyuan3D-PolyGen，通过自研高压缩率表征BPT技术与自回归网格生成框架，实现了上万面复杂几何模型的精准生成。该模型突破性解决了3D资产生成中布线质量差、面数过高、后期编辑难等核心痛点，将美术师建模效率提升超70%，相关能力已上线腾讯混元3D AI创作引擎并集成至多款游戏管线。
传统3D生成算法虽能快速构建几何模型，但生成的网格面数过高（常达数十万面）、布线杂乱无章，导致模型美观度不足且难以直接应用于游戏开发。腾讯混元3D-PolyGen采用“网格序列化-自回归建模-序列解码”三步框架，将网格顶点和面片转化为离散Token序列进行空间推理，
