Unable to load from ./assets/models/knapp.obj: Error in onSuccess callback

Questions

I am trying to load a OBJ file, but I am having problems. Now I get this error:

Unable to load from ./assets/models/knapp.obj: Error in onSuccess callback

My code in index.php looks like this:

<!-- Link to the last version of BabylonJS -->
<script src="https://preview.babylonjs.com/babylon.js"></script>

<!-- Link to the last version of BabylonJS loaders to enable loading filetypes such as .gltf -->
<script src="https://preview.babylonjs.com/loaders/babylonjs.loaders.min.js"></script>

<!-- Link to pep.js to ensure pointer events work consistently in all browsers -->
<script src="https://code.jquery.com/pep/0.4.1/pep.js"></script>

<!-- Local JS script -->
<script src="script.js"></script>

And inside scripts.js I have this in the import section:

        BABYLON.SceneLoader.Append("./assets/models/", "knapp.obj", scene, function (scene) {
            scene.createDefaultCameraOrLight(true, true, true);
            object.scaling = new BABYLON.Vector3(10, 10, 10);
        });

I think your onSuccess callback is shadowing your scene object. The onSuccess callback should have meshes, skeletons, etc. Also, object may be something like meshes[0]?

BABYLON.SceneLoader.Append("./assets/models/", "knapp.obj", scene, function (newMeshes) {
        scene.createDefaultCameraOrLight(true, true, true);
        newMeshes[0].scaling = new BABYLON.Vector3(10, 10, 10);
    });

Thanks brianzinn, I tried it and I still get:

A repro in the Playground would definitely help here.

Sorry, what do you mean with a repro in the playground ?

You should try to recreate your problem here: https://playground.babylonjs.com/

That way, it will be easier for people to help you.

Aha, thanks. Does this work?

It does not work because you can’t mix http and https in the same page: your asset should be delivered through https.

This doc is explaining how to host a file to be used in the Playground: Using External Assets - Babylon.js Documentation

You don’t get the new meshes from the Scene.Append callback but the scene, so you should do something like:

BABYLON.SceneLoader.Append("temp/", "Knapp.01.006.baked.size.obj", scene, function (scene) {
    scene.createDefaultCameraOrLight(true, true, true);
    scene.meshes.forEach((m) => m.scaling = new BABYLON.Vector3(10, 10, 10));
});

It works now, but then it is my other code that mess it up.

It works now local too, thanks :slight_smile:
