HomeTencent Open Sources Huan Yuan 3D World Model 2.0 for One-Click Editable 3D Space Assets
Tencent's Huan Yuan team today announced the release and open-sourcing of "Huan Yuan 3D World Model 2.0" (HY-World2.0), a major upgrade to its multimodal world model. This version marks a shift from simple video generation to creating interactive, editable 3D assets. It supports text, image, and video inputs, enabling the generation, reconstruction, and simulation of complete 3D spaces that include people, objects, and scenes. The model also exports in multiple formats such as Mesh, 3DGS, and point clouds, and integrates seamlessly with mainstream game engines like Unity and Unreal Engine.
On the technical side, HY-World2.0 unifies spatial understanding, generation, and reconstruction into a single process. Key upgrades include the HY-Pano-2.0 model, which uses an end-to-end implicit learning approach to generate 360-degree panoramic maps without requiring camera parameters; a self-developed spatial agent that combines VLM with navmesh representation, enabling intelligent roaming trajectory planning; and the WorldStereo mechanism, which ensures high consistency in geometry and visual appearance between newly generated areas and existing scenes.
Additionally, the upgraded WorldMirror2.0 architecture replicates real-world scenes by predicting dense point clouds and camera parameters in a single pass, enabling high-precision digital twin construction.
Compared to mainstream models like Google's Genie3, Huan Yuan 2.0 stands out because its generated assets feature realistic physical collision properties and support free exploration in character mode. This significantly lowers the barrier to building game level prototypes and embodied intelligent simulation environments.
This release marks an evolution for Tencent Huan Yuan from "manipulating objects" to "creating worlds" in 3D generation. With a state-of-the-art spatial consistency memory mechanism, it pushes AI-driven 3D content creation into a practical, real-world phase.
