Meshyai

Turns natural language prompts into game-ready 3D models through Meshy AI's API, handling the full pipeline from generation through rigging and animation. Built for Three.js game development with automatic optimization that cuts GLB sizes by 80-95% through texture resizing and meshopt compression. The auto-rig feature is especially practical: it takes a humanoid model and outputs not just the skeleton but pre-downloaded walk and run animations as separate GLBs. Makes the most sense when you need a specific character or prop that doesn't exist in free libraries, or when you want stylistic consistency across custom assets. Falls back gracefully to Sketchfab and local geometry if you don't have an API key.
