1# Scenario 3D Worlds
2 
3## Overview
4 
5These models build explorable environments as 3D Gaussian splats, not polygon meshes: volumetric
6scenes to walk through and render in real time, with no UVs or topology to edit (Marble splats also
7export to triangle or collider mesh). Three vendors sit side by side: World Labs Marble in three
8quality tiers, Hunyuan's HY World pipeline, and TripoSplat for single objects. Discover them with
9`search` and treat `model_schema_get` as the contract; HY World members carried a geo restriction
10tag at authoring time, so hits differ by team and region.

12Connection and the core loop: see the `scenario` skill; polygon meshes, rigging, and the 3D viewer:
13the `scenario-3d` skill; skybox-only work with no splat stage: the `scenario-skyboxes` skill. If a
14sibling skill named here is missing from your available skills, load it with `skill_get` (Scenario
15MCP) or ask the user to install it (https://github.com/scenario-labs/skills#install); unattended,
16proceed from tool schemas and flag the gap.
