Exporters and importers are just classes coded in GDScript, which create either a string or a binary buffer according to the format specification, and write them to disk. You can find them in the io folder, and the GUI hooks are in the IOManager class.
That’s why I mentioned the IOManager class. That’s where the GUI is connected to the logic behind the export process. That’s where user interactions are handled, and then an exporter class handles the rest.
Please stop posting the same question over and over. As I’ve said, I’ll get back to you on GitHub once I have time. I appreciate your desire to help, but spamming is not helpful.
