Hi,  
Exporting GLB on serverside/Node.js doesn’t work.

It works on browser, when I implement exactly same code below.

> **[Babylon.js Playground](https://playground.babylonjs.com/#5KB36A)**

> Babylon.js playground is a live editor for Babylon.js WebGL 3D scenes

In serverside, I got empty data.

```auto
BJS - [15:14:55]: createNodeAsync: Light falloff for Lamp does not match the KHR_lights_punctual specification!
GLTFData { glTFFiles: { 'test.glb': {} } }

```

Hi.

GLTF2Export and how it works on browser side is pretty much it creates an anchor () element and initiates download. So pretty much it’s doing this

But this means that the function interacts with DOM, which on server side is not available. So I don’t think you can use that approach on server side. I had similar issue lately, and you can check out here how I solved it.

I’ve created a File object on the front and sent the data to the node.js server, where I created a write stream and stored it at the specific location. // on the front-end [image] // on the back-end [image] On the server side, you also need to add middleware for processing request body as a Buffer.
