    Preparing search index...
    • Loads every car model listed in carFiles using MTL + OBJ loaders. Results are cached so subsequent calls return immediately.

      Each loaded group stores its original carFiles index in model.userData.carFileIndex so the mapping survives even when some models fail to load.

      Returns Promise<Group<Object3DEventMap>[]>

      A promise resolving to an array of Three.js groups.
