This is a tier-based 3D model pipeline that moves you past primitive cubes and spheres when building Three.js browser games. It defaults to Meshy AI text-to-3D generation for custom assets, then falls back through a pre-built character library (Soldier, Xbot, RobotExpressive, Fox with walk/run animations already wired), then Sketchfab and Poly Haven. The gesture character set (Trump, Biden) is a nice touch for stationary gameplay like debates or rhythm games. The tier system is practical: it checks for API keys before prompting, logs animation clip names per model since they're inconsistent, and knows when to use rigged humanoids versus static props. Saves a lot of manual asset hunting when you need recognizable entities instead of placeholder geometry.
