Loading obj file

[Tomm Huth]

I'm trying to load a simple obj file exported from Blender, but I'm having a hard time and the docs aren't really helping. I've tried

SceneLoader.ImportMesh(["rock1"], "./","rock1.obj", scene, function (meshes) {

console.log(meshes)

});

But what are the params supposed to be here? I have one single file named "rock1.obj" located at root "/". But then Babylonjs tries to get this:

 GET http://localhost:3000/rock1.obj.manifest?1540314526858  
 GET http://localhost:3000/rock1.mtl 

Even when 

SceneLoader.IsPluginForExtensionAvailable(".obj")

return true. I dont want to automatically add the mesh just get it and store it for future use. 

Also am I forced to load scenes for every object? 

The same thing happens when I use

let loader = new AssetsManager(scene);

loader.useDefaultLoadingScreen = false; // Set to false to remove the default loading

let mesh_loaded_task = loader.addMeshTask("s", "rock1.obj", "/", "rock1.obj");

 

mesh_loaded_task.onSuccess = function (task) {

task.loadedMeshes.forEach(function(m) {

console.log("Loaded!");

m.position = BABYLON.Vector3.Zero();

});

};

mesh_loaded_task.onError = console.error

 

loader.load()

But what is the last parameter of addMeshTask supposed to be -- sceneFilename??

You can use the asset container to load a mesh without it being added to the scene by default.

I obj's can have a manifest and mtl file associated with them so the obj plugin will look for those and if it doesn't find them it should still load the obj.

You shouldn't need to create a new scene for every object but you should have at least one scene.

@trevordev see my last edit. 

Babylon never hits my rock1.obj file at all, and fails with the following error

"Unable to import meshes from ./: importMesh of undefined from undefined version: undefined, exporter version: undefinedimportMesh has failed JSON parse" SyntaxError: Unexpected token < in JSON at position 0

You're example also uses a glb file type, is that interchangeable with obj? If not how do i convert it?

@trevordev ah looks like 

SceneLoader.LoadAssetContainerAsync

 

does the trick but my mesh is still added to the scene, any ways of stopping that?

[Tomm Huth]

Seems like there is a bug here with 

SceneLoader.LoadAssetContainerAsync

The promise never resolves, but somehow the mesh is added to my scene (I haven't even passed   thru my scene anywhere, so don't know how it knows that). It also complains alot about not finding the mtl file

Can you provide a playground http://playground.babylonjs.com/ for what you are seeing for me to take a look?
