Hi Drekmonger,
It’s actually .csv import, so anything that can export to .csv will work; our designers use Excel. It’s not currently exposed to Blueprints, you need to create new subclasses of FTableRowBase with the properties you want to import, and UDataTable stores/manages a collection of rows. We’d like to improve access to this data in Blueprints in the future, but don’t have any immediate plans, although custom struct support will probably make it much easier now.
Cheers,
Michael Noland
