I just tried it and I get the error:  
ERROR: ‘BJSMaterial’ object has no attribute ‘materialNameSpace’

Here the full log:

Here was the answer of JCPalmer:

> [@Blender 6.0 exporter for Blender 2.80](https://forum.babylonjs.com/t/blender-6-0-exporter-for-blender-2-80/957/56):
>
> materialNameSpace was removed for 6.1. I searched the entire source, it is missing. When you upgrade, always restart Blender. Also, this is an old topic & also very long. It is better for future searchers to have short topics. @Deltakosh, please close this one.

@JCPalmer, I am not sure I understand what I need to do to make it work…?

I opened an issue in Github to track it: [ERROR: 'BJSMaterial' object has no attribute 'materialNameSpace' · Issue #3 · BabylonJS/BlenderExporter · GitHub](https://github.com/BabylonJS/BlenderExporter/issues/3)

Hope that helps.

I double checked line 49 of materials.py in the zip file, and it is setting the environmentIntensity. When an error stack, in the last line, shows something that is not even referenced in the error statement, it means that the code must have changed, after it was loaded into memory, usually upgrading.

I always restart after loading (many times a day during dev). The first thing I would do is either

- delete c:\Users\goeff\Appdata\Roaming\Blender foundation\Blender\2.80\scripts\addons\babylon\_js
- Start Blender
- install from scratch

or

- Bring up preferences.
- goto Addons / BabylonJS
- expand & cleck the remove btn

I do not know what went wrong, but chasing ghosts is not recommended.

I also tried exporting a material by baking, which you export is triggering, and it work on my system. Even if doing a clean install of addon clears issue, results might not be as expected when baking in the exporter.

I did your first solution, and here is the new error I’ve got:

```

Also, is it possible not to trigger the baking?

Ok I can reproduce with  
 ![emissive](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/2X/6/60d78d173ede9eb722caa8209cfac6e6c4814147.jpeg)

If you do not wish baking, remove ‘Add Shader’. A ‘Mix Shader’ is supported, so a bake might be avoided with a substitution. Hanging everything off a ‘Principled Shader’ works best.

Also, every mesh is using Custom split normals. Where did these meshes come from a CAD system?

Fixed with 6.1.2

The mesh comes from 3Ds max, in FBX format. I believe that my colleague used a tool in 3Ds max to make hard edges… not sure.
