Exporting multiple meshes using the glTF exporter

When exporting multiple meshes using the glTF 2.0 exporter in Blender, I notice that the rotation of the gun mesh needs to be flipped in order for it to work properly. Is this a bug? The gun mesh is parented to the bone.

I think the exporter currently has some bugs with meshes parented to bones. If you could file an issue on the github repo someone will take a look!

Ok, Thanks!
