Scenario 3D Worlds Overview These models build explorable environments as 3D Gaussian splats, not polygon meshes: volumetric scenes to walk through and render in real time, with no UVs or topology to edit (Marble splats also export to triangle or collider mesh). Three vendors sit side by side: World Labs Marble in three quality tiers, Hunyuan's HY World pipeline, and TripoSplat for single objects. Discover them with and treat as the contract; HY World members carried a geo restriction tag at authoring time, so hits differ by team and region. Connection and the core loop: see the skill; polygo…
