I have just released an update of ModelConverterX that adds initial DSF support for X-Plane. You can now read and write DSF files.
If you read an X-Plane DSF file the models referenced from it and the placement of those models will be imported.
If you write an X-Plane DSF file the file save dialog will ask you for the location the DSF file. You should go to the scenery folder of your choice and then press enter. The name you enter doesn’t matter. ModelConverterX will automatically make a folder objects to save the objects and a folder “Earth nav data” with the correct subfolders to store the DSF file.
Be aware that the DSF exporter does at the moment not merge what you save with existing DSF files. So if they already exist they will be overwritten!
If an object has multiple textures than the X-Plane OBJ and DSF exporters will make sure that multiple objects are exported and that these are all placed at the same location.
I’m sure there will be some bugs remaining, I’m still learning X-Plane as well, so let me know if you find something.
