Error: Package .uasset is too new

Hi

I have a UE4 project. I have pushed all files to master branch. One user has successfully pulled the project into his machine (master). Another user cloned the project successfully but when looking in the directories, all the folders are there but there are a lot of files missing. We are all using 4.26. Checking the output log, the user gets this.

LogAssetRegistry: Error: Package <folder directory>MI_White_Gloss_Ceramic.uasset is too new

Over and over again for each missing file. This happens every time it opens. I have also rebuilt visual studio files.

I also have this error with 4.26 after upgrading from 4.25. I’ve not yet figured out what the issue is but i’ll be working on it and will let you know if I manage to find anything. Is this still an issue for you?

Thanks

EDIT

I found that i have files visible in Windows Explorer in these directories that are not part of the UE4 Asset browser, i assume this is the problem. I am going to try deleting all the explorer files that i don’t need and ensure that none of my material references break, then will package again. I hope this will fix it.

It could be a 4.25->4.26 upgrade issue.

I’m getting a similar error when tryin to migrate a few assets from UE4 project to UE5 project. Below are the steps that I’m trying:

  1. Create a local UE4 project with only the blueprint that I need and its dependencies
  2. Convert this local UE4 project to a local UE5 project by opening it as a copy using the UE5 engine from the Epic Games Launcher.
  3. Once converted, migrate that blueprint from the local UE5 project to our main UE5 project.

The UE4 project gets converted to UE5 successfully but I only see the folders for the blueprint and its dependencies, and not the actual assets. The errors I get in the output log are along the lines of “.uasset is too new. Licensee Version: 0 Package Licensee Version: 1”.

Anyone knows a solution to this yet?

I also had a very similar issue to this - I had several log entries say the asset is to new, but when I navigated to the folder in the editor - The folder was empty.

When I went to the same folder in windows browser it had the UE assets in them. I wasn’t using any of these assets in the project (or could have replaced them), so I just deleted the windows folder directly (as it wasn’t deleting via the editor). I would exercise caution doing this, make sure you have a backup of the project and also have ran the fix up redirectors from the top level content folder.

After I deleted these folders though the build worked.

This is because the file “MI_White_Gloss_Ceramic.uasset” was imported from an asset that was modified/saved in a newer version of Unreal Engine. For example, a file in a project was opened and saved in version 26.02, and you are trying to open it in version 26.01.
The solution in this case is to delete the file from the project (via Windows explorer) or add the entire folder to exceptions if it is not needed in the project (Project Settings → Packaging → Directories to never cook).
Or better to install a version of Unreal Engine no lower than the one in which the project was modified.
