In newer versions the glb export (GLTF2Export.GLBAsync) loses the Material.  
Same Playground on different versions:  
[Babylon.js Playground](https://playground.babylonjs.com/#8AIAXC) - version 8.14.1 doesn’t work  
same link with version 5.57.1 does work

(i use blender 4.1 to check if the material is on the sphere)
