Viggle launches JST-2, a physics-native 3D world model that skips rigging
Aiden_Tech_Ai · x · 2026-10-20
Viggle released JST-2, billed as the world's first full-stack physics-native world foundation model. Instead of learning in pixel/video space, the entire stack is built in 3D: generate a 3D scene in seconds, expand it in real time, and create characters with motion built in — all from one general architecture.
Community reaction focuses on game workflows: JST-2 turns a single image into an animation-ready character with no rigging or skinning step, and agents can call it via the PINOC MCP server — potentially ending manual character rigging for vibe-coded games.
