Can neither export complex models nor retain material properties of simple models

[lacnunga]

Hello

I have tried the latest version of this plugin and noticed that when the scene to be exported using the plugin is complex, it returns // Error: line 0: Could not save file whether the models have external links or not. When the scene is simple enough, it can export in glTF format, but all of the material properties are lost regardless of export settings.

Any idea how the material properties can be kept after exporting?

In the Readme file it says:

• Recommend StingrayPBS shader for best material conversion.

I used that shader and it worked file apart from the names that are lost.
