How do I import packages with Prefabs to Update my package automatically?

I have imported my artist’s newest package of prefabs and want to integrate it into my project. I am working with grayboxed prefabs that I would like to automatically update after importing the artist’s most current package. The naming conventions for all prefabs have stayed the same between versions and importing the new version seems to create a second prefab in my folders, with a number “1” added to the end. What is the best workflow between teams of artists to bypass this problem? Thank you in advance!

In Unity 5 they have changed it such that they append “1” instead of replacing files with same name. I don’t think there’s a solution for that (yet).

As for workflow, it’s a good practice to talk to your artist beforehand about naming conventions. It’d be a good practice to group every assets in the package inside a folder, one single uniquely named folder. Let’s say your artist have; textures and models, instead of importing textures and models folder, put both of these folders into a main folder before exporting.

Now when you’re importing a package, you can just delete (make a backup, or keep the old .unitypackage) the old package folder before importing so there won’t be naming conflicts.
