Open-weights model that generates explorable 360° 3D worlds from text or an image, with mesh export for standard graphics pipelines. Tencent has since released newer HY-World versions under separate repos.
Generates persistent 3D worlds from text, images, video, 360° panoramas or blocked-out 3D layouts. Exports Gaussian splats and GLB meshes, and records camera flythrough videos.
Verdict
For self-hosting 3D world generation with mesh export; the licence excludes the EU, UK and South Korea, and large products need Tencent's approval.
For blocking out explorable environments or flythrough shots; exports go to Unity/Unreal via Gaussian-splat plugins, and commercial rights are listed on Pro.
