Well, my packaging doesn’t go further for some reason.
This messages got resolved for another material by duplicating it and removing the original one.
But I don’t want to do it for every ******* material I created.
Solution?
Migrating assets to another project is not the solution.
Deleting Saved/Intermediate/Build/Binaries Folders aren’t working, too.
Fixing the Redirectors doesn’t help, either.
