Loading gltf files with Three.js does not automatically update external variables

When I import a gltf object, it seems to render in the browser but I am unable to access it using an outside variable. What could be causing this issue?

let loadedModel;
gltfLoader.load('./assets/javaLogo.gltf', function(gltf){
    loadedModel = gltf.scene;
    loadedModel.scale.set(44,44,44);
    scene.add(loadedModel);
    loadedModel.position.x = 44;
    loadedModel.position.y = -12;
});
console.log(loadedModel);// This prints 'undefined'

Answer №1

When you initiate the model loading process, the console.log statement is executed immediately, even before the model has finished loading. To confirm this, you can place another console.log inside the callback function, which will only be executed after the initial log that outputs 'undefined'.

If you need to access the model right after it finishes loading, you can do so within the callback function. However, if you plan to access the model in an event listener or similar scenario, ensure that the model is no longer undefined before proceeding.
