Express.js with Babylon files

Recommended Posts

The newest Express doesn't really seem to be handling the Babylon files correctly, even after setting the mime types.

I'm using express.static with a folder, and every time BabylonJS downloads the file but doesn't create a mesh afterwards. Going to the link directly in your browser downloads the mesh instead of showing the data (not sure if this is intended)

The appropriate mime types are set, looking them up by file extension also returns these types.

 

Basically the code to have the mime types is this:

express.static.mime.define({    'application/babylon': ['babylon'],    'application/fx': ['fx'],    'application/babylonmeshdata': ['babylonmeshdata']});app.use(express.static('YOUR FOLDER'));

Client:

BABYLON.SceneLoader.ImportMesh("test", "objs/", "skull.babylon", scene, function (newMeshes) {	console.log("mesh loaded");	console.log(arguments); // This logs: [Array[0], Array[0], Array[0]]});

skull.babylon is the skull which you see often on the Babylon playground.

 

The Chrome Networking tool returns this for skull.babylon:

It seems that the networking tool actually does get the correct information:
 
But that "newMeshes" in the client code returns an array of size 0

Hi,

Would you be able to show us the setup? Or maybe publish a demo page temporarily?

A Babylon file is a simple static file, I would assume there wouldn't be any problem serving it.

What mime type have you tried?

I've edited the main post a few minutes before you posted this :)

 

There's not really something else.. There's no other setting that I'm changing or something.

The weird thing is that this works:

var assetsManager = new BABYLON.AssetsManager(scene);var meshTask = assetsManager.addMeshTask("skull task", "", "./objs/", "skull.babylon");// You can handle success and error on a per-task basis (onSuccess, onError)meshTask.onSuccess = function (task) {	task.loadedMeshes[0].position = new BABYLON.Vector3(0, 0, 0);}// But you can also do it on the assets manager itself (onTaskSuccess, onTaskError)assetsManager.onTaskError = function (task) {	console.log("error while loading " + task.name);}assetsManager.load();

But BABYLON.SceneLoader.ImportMesh doesn't
