AI-powered, browser-native game engine for building high-quality 3D worlds and physics simulations — instantly, from a prompt. It repurposes Bolt.new from website generation to real-time Three.js world generation, integrating:

Needle Progressive GLTF for streaming environments & characters from the cloud
Dynamic Physics Engine Switching — from lightweight (Cannon) to heavyweight (Rapier, Havok, PhysX WASM) for fidelity control
VRoid / GLTF Avatar Support with rigging, retargeting, ragdoll physics, and third-person controllers
Action-based AI World Builder that can spawn, edit, and reconfigure a scene in seconds
