# 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, load it with `skill_get` (Scenario
