glTF Exporter

The glTF Exporter allowsBabylon.js models to be exported to the glTF 2.0 format.


The glTF Exporter can be installed by using the babylonjs-serializers module


npm install --save babylonjs babylonjs-serializers


yarn add babylonjs babylonjs-serializers


To include theBabylon.js serializers in javascript, include a script tag in the html <head> tag, referencing the non-minified or minified compiled javascript:

<!-- links to the latest version of the serializers -->
<script src=""></script>
<!-- links to the latest version of the minified serializers -->
<script src=""></script>

If only the glTF serializer is desired, it can be specifically targeted with this <head> tag:

<!-- links to the latest version of the glTF serializer -->
<script src=""></script>
<!-- links to the latest version of the minified glTF serializer -->
<script src=""></script>

Exporting a Scene to glTF

BABYLON.GLTF2Export.GLTFAsync(scene, "fileName").then((gltf) => {

To download to glb format, simply replace the GLTFAsync static function with GLBAsync:

BABYLON.GLTF2Export.GLBAsync(scene, "fileName").then((glb) => {

Export options

glTF Exporter accepts an optional options parameter with certain functions and properties defined.

Excluding geometry

Sometimes you may need to exclude geometry from export, such as the skybox. You can define a boolean callback called shouldExportNode which accepts aBabylon.js node as an argument and returns a boolean, specifying if the node should be exported or not:

// Initializer code...
let skybox = scene.createDefaultSkybox(hdrTexture, true, 100, 0.3);
// scene setup code...
let options = {
shouldExportNode: function (node) {
return node !== skybox;
BABYLON.GLTF2Export.GLBAsync(scene, "fileName", options).then((glb) => {
