UPDATE - So, it turns out I was missing the step of first loading the UE4 project into UE5 to convert the project, and THEN migrating the materials. Surely there HAS to be a better way? No?
Been trying to bring in some material packs from the Marketplace but they all say they’re not compatible. Tried importing to 4.26 then migrating, but that’s not working either. Is there any fix for this at all?
