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

r/robotics · April 20, 2026

AI Summary

  • •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
