Thanks I think I should be able to work something out with EditorPostImport to export the branches/update them if they exist.

EditorPostImport sounds promising. Hopefully I can make it save the branches or update them if they already exist. Thanks!

What about modifying the importer to automatically export each branch to a new scene?

Python syntax makes me really have no interest in gdscript. I don’t understand why people like python/similar languages. Its painful to use.
