Exporting a Shaded Texture model as .glb with "custom properties" crashes with error message.

[Boxingbruin]

When trying to export a 3d model with Fast64 materials that are shaded textures with a texture applied to the object, exporting as a .glb file with "custom properties" blender crashes on version 4.2.1 and outputs an error on versions 3.3 and 3.6.

I am unable to export a textured object as .glb with custom properties enabled.

This is a problem with the gltf addon, we can't fix it on fast64

Weird that this wasn´t showing up in my glTF pr #368 , but yes like dragon said we can´t do much, they're relying on deep copy to make a material copy instead of material.copy()
