Tencent's HY-World 2.0 eliminates quality loss in AI-generated 3D environments by outputting usable assets directly instead of converting from video.

HY-World 2.0 generates 3D assets (meshes, 3DGS) directly importable into Isaac Sim, Unity, and Unreal, bypassing the problematic video→3DGS→mesh conversion chain

Previous approaches like Genie 3 and Cosmos output only pixel videos, while WorldLabs' Marble generated 3DGS but still suffered from poor mesh conversion and artifacts

Direct 3D generation significantly reduces information loss and artifacts that plagued traditional conversion pipelines

For robotics, this enables rapid generation of varied training environments and domain randomization, though handcrafted environments may still be superior for specific applications
