Development Asset Creation

Hello , I’m trying to downgrade my UE5 project 5.2 to the older version 5.1

i have done the following.

  1. go to my UE project folder
  2. click in *.uproject file and “switch unreal version” from 5.2 to 5.1
  3. the project is opening in the old versions but is missing all the level maps, on the folder i can see the maps but not in the editor.

Hey @imagineer.

Unfortunately, assets created in newer versions are not backwards compatible. You will need to recreate or reimport those assets for them to work.

Good luck on your downgrading efforts!

I made a plugin ( Asset Downgrader | Fab) that does just that, downgrades assets all the way back to 4.27, with certain limitations (for now). Let me know if it works or have specific needs.
