IT之家 6 月 14 日消息，腾讯官方公众号今日凌晨宣布，在 CVPR2025（计算机视觉领域顶会之一）上，腾讯宣布混元 3D 2.1 大模型对外开源，这是首个全链路开源的工业级 3D 生成大模型。
新模型既优化了几何生成的质量，也开放了 PBR（基于物理的渲染）材质生成大模型，进一步提升 3D 资产的质感和光影表现，告别“塑料感”。
据官方介绍，新模型优化了细节建模，使网格精度更高，具备更好的拓扑一致性，为后续纹理映射提供了基础；还可生成基础颜色、金属度、法线、粗糙度等贴图，支持皮革、木质、金属、陶瓷等多种复杂材质的高质量渲染。
混元 3D 2.1 模型适配于消费级显卡，在个人电脑也能“跑”，还在 Github 等开源地址提供了详细部署和使用教程，帮企业、中小团队及个人开发者轻松上手。
