This post will have both the question and the solution. So that others might get the help they need.
–The Issue–
So I have had these errors show up for a while. Unreal can’t find the packages required to cook certain assets.
But these assets don’t exist in the content browser of the unreal editor.
–What Others Suggested–
So I followed the advice i could find using google. Which was to fix up re-directors and delete the intermediate and saved folders in the project directory. Naturally this didn’t work.
–Inquiry–
So after investigating it myself I discovered that Unreal isn’t the greatest at deleting assets. Sometimes even though the content browser tells you there is nothing there, using windows file explorer the assets still remain in the project.
–The Solution–
(Before attempting this back up. In case your problem is something else)
The solution is actually very simple. Close down your Editor. Using file explorer, remove the assets manually from the project folders (Just delete them). They are deleted assets left behind anyway. This will fix the references to assets that no longer exist and fix your error codes.
Good luck guys and girls I hope this helps some of you.
