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。
