Hi everyone,

It should be great to add some items to the babylonjs exporter. For instance :

- area lights
- GUI
- Sprites
- Crowd navigation system

And may be some more which are implemented and cannot still be saved in the .babylon JSON.

Thanks

Yeah, the `.babylon` serializer should already support Sprites. I’m at least able to serialize this PG: [https://playground.babylonjs.com/#YCY2IL#2516](https://playground.babylonjs.com/#YCY2IL#2516).  
@bvaisman , could you share a repro where Sprites or GUI don’t export correctly? Thanks in advance!

GUIs, however, don’t look like they’re included in the `.babylon` serializer. But they definitely have _a_ serialization mechanism that is used by the GUI editor.

Hi @alexchuber

You’re right about the sprites (but not written in the docs [Babylon.js docs](https://doc.babylonjs.com/setup/support/.babylonFileFormat)) but I think it is not possible for the GUI. Here’s a PG :

> **[Babylon.js Playground](https://playground.babylonjs.com/#YCY2IL%232518)**
>
> Babylon.js playground is a live editor for Babylon.js WebGL and WebGPU 3D scenes

Thanks for your help

Thanks for the PG. We should update the docs to include Sprites 🙂

You’re correct that GUIs are not exported in the `.babylon` format.

If anyone would like to contribute a PR for this, there are already [serialize and parse](https://github.com/BabylonJS/Babylon.js/blob/7f5a25ecc89bf496559e8b040d6f39fef2f77944/packages/dev/gui/src/2D/advancedDynamicTexture.ts#L1412) methods for GUI. They just need to be included somewhere in the [SceneSerializer](https://github.com/BabylonJS/Babylon.js/blob/7f5a25ecc89bf496559e8b040d6f39fef2f77944/packages/dev/core/src/Misc/sceneSerializer.ts#L140).

I’ve made a PR to add the sprites to the docs :
