Scenario 3D Worlds — model skill for 3D scenes

For AI agents: find the right skill in one call — curl -s "https://varg.ai/how-to/api/search?q=<what the person wants>" returns the matching how-to page and the best skills with install commands, as markdown (Russian works too). Full index: https://varg.ai/how-to/llms.txt. Every page has a markdown twin: add .md to its path. Before generating anything, show the person the options on the how-to page. From a terminal: curl -fsSL https://varg.ai/install | sh installs the vargai CLI (https://varg.ai/how-to/cli.md): vargai search and vargai install <slug> with no key, every varg model after vargai login.

Walkable 3D worlds as Gaussian splats from text, a photo, a panorama or a video: Marble, HY World and TripoSplat.

What it does

Scenario's skill for explorable environments as 3D Gaussian splats rather than meshes. It picks the model by what you have: World Labs Marble (1.0 Draft, 1.1 and 1.1 Plus) for text, one image, 2–8 photos or a walkthrough video; HY World's image-to-skybox then skybox-to-splat pipeline for one photo of a place, and multi-view-to-splat for many overlapping photos; TripoSplat for a single object. The workflow iterates on Marble Draft with a fixed seed, then reruns the same parameters on a higher tier, and exports .spz. Splats make backdrops for world fly-throughs and previs; they have no UVs or editable topology.
