Error in UEFN when trying to access team members map

Development Getting Started & Setup

I am getting an error when trying to access a team members map. I was able to access some of their maps, but some of them I receive an error and we tried everything but cannot figure out how to fix the issue. The error I am receiving is “No revision given and no remote configured” not entirely sure what this means. My team has said that Unreal Revision Control is enabled and working as I mentioned earlier I was able to access their other maps no issue. But when I press “Sync” on certain maps I get the error I mentioned above.

The error “No revision given and no remote configured” usually appears when Unreal’s Source Control system (Revision Control) cannot determine which version/revision to pull for that specific map, often because the remote repository connection is not fully set up or the file has an inconsistent history.Even if it works for some maps, it can fail on others if they were added/submitted differently or if the project’s source control connection is partially broken.Things to Try (in order):

  1. Re-connect Source Control

    • Go to Tools → Connect to Source Control (or click the Source Control button in the bottom right).

    • Choose your provider (Git, Perforce, etc.) and re-enter / verify the credentials.

    • Restart the Editor after reconnecting.

  2. Force Sync the Specific Map

    • Right-click the problematic map in the Content Browser.

    • Choose Source Control → Sync (or Checkout first if available).

    • If that fails, try Source Control → Refresh on the file or the parent folder.

  3. Check Remote Configuration

    • Close Unreal Editor.

    • Open your project in your source control client (GitHub Desktop, Git Bash, Perforce P4V, Plastic, etc.).

    • Make sure you are on the correct branch and pull the latest changes from the remote.

    • Then reopen Unreal and try syncing again.

  4. Additional Fixes

    • In the Content Browser, right-click the map → Source Control → Fix Up Redirectors (if any exist).

    • Delete the map’s .uasset and .umap files locally (after backing them up), then sync them fresh from source control.

    • Check Editor Preferences → Loading & Saving → Source Control for any weird settings.

Question for more help:

  • Are you using Git, Perforce, Plastic SCM, or something else?

  • Does this happen only on maps created by certain team members?

This error is frustrating but usually fixable with a good pull + reconnect. Let us know what source control system you’re on and what happens after trying the reconnect step. Good luck!
