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 search and treat model_schema_get 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 scenario skill; polygon meshes, rigging, and the 3D viewer: the scenario-3d skill; skybox-only work with no splat stage: the scenario-skyboxes skill. If a sibling skill named here is missing from your available skills, ask the user to install it (npx skills add scenario-labs/skills --skill <name>); unattended, proceed from tool schemas and flag the gap.
