JST-2 / Capability guides

JST-2 features.
Scenes, characters & motion.

Explore the scenes, characters and motion in Viggle’s JST-2 world model. Each guide explains its inputs, outputs and limits, and separates the official model from the tools in this independent studio.

Find your JST-2 workflow

Text to 3D scene

Create a 3D scene from a text prompt with JST-2. Learn what to describe, how to review your panorama, and what the downloadable SPZ file contains.

3D world expansion

Understand JST-2 world expansion, its spatial context window and sparse-view reconstruction, with a clear distinction between released and upcoming features.

3D character generation

Create an animation-ready 3D character from an image with JST-2. Learn how to prepare a reference, review the VSPLAT result and apply compatible motion.

Text to motion

Describe an action for JST-2 full-body 3D motion. Learn how to write useful motion prompts and check timing, foot contact and character compatibility.

Video to motion

Learn how JST-2 reconstructs full-body 3D motion from video, how to prepare reference footage, and why body movement differs from a path through a scene.

Gaussian splatting

Understand JST-2 Gaussian-splat scenes, the SPZ download format and browser rendering. Learn why a splat is different from a panorama or polygon mesh.

JST-2 API

Plan a direct Viggle JST-2 API integration. Understand scene, character and motion workflows, returned assets, and how API credentials differ from site credits.
