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!

Hi there, thank you for your response!

I was reading through the things you mentioned to try and see if I could fix the problem. The first two solutions I am not sure how to do. For the first solution you mentioned “Go to Tools” I cannot find that anywhere. I don’t think I mentioned before, but I cannot access the map whatsoever. I can’t load into the project to access the editor or anything beyond the main menu screen where all of the projects are located. When I go to the Project Browser and then click on the map I want to access and click the blue “Sync” button at the bottom. It begins the syncing process but after about 5 seconds it fails and I get the “No revision given and no remote configured” error.

In terms of your second solution, when I right click on the problematic map in the browser all of the options are greyed out aside from “Copy verse path” and the option you wanted me to select is not there whatsoever.

I am not sure what you mean by “Are you using Git, Perforce, Plastic SCM, or something else?” I have no idea what any of those are. The only thing I am using is Unreal Revision Control.

To answer your second question, it is just me and one other person in this team. Some of the maps work and then some do not.

Thanks!

Thanks for the extra details — this changes things. Since you cannot open the project at all, we have to fix the source control issue from outside the editor.Important Clarification:“Unreal Revision Control” is just the name of the system inside Unreal. Under the hood, your team is probably using Git (most common), Perforce, or Plastic SCM. The error “No revision given and no remote configured” almost always means the connection to the actual repository is broken or not set up properly.Steps to Fix (Do These in Order):

  1. Close Unreal completely

  2. Find your Project Folder

    • Go to the folder where your project is saved on your computer.

  3. Try a Manual Sync (Best First Step)

    • Inside your project folder, look for a hidden folder called .git (if you see it, you’re using Git).

    • If you have Git installed, open a command prompt / terminal in your project folder and type:

      git pull

    • Or better:

      git fetch
git pull origin main

      (replace main with master if your branch is called master).

  4. Reconnect Source Control in Project Browser

    • Open the Project Browser (the window with all your projects).

    • Click the small Source Control button at the bottom left of the Project Browser.

    • Click Connect to Source Control → Choose your provider (try Git first) and reconnect with the same settings your teammate used.

  5. If Git is Not Installed or You See No .git Folder

    • Ask your teammate: “What source control system are we using?” (Git, Perforce, or Plastic?)

    • Have your teammate send you a fresh copy of the problematic maps, or ask them to delete and re-upload those specific maps.

I checked the project folder for one of the maps that wasn’t working and the only thing that is in there is the “.urc” folder and nothing else. I checked another folder for one of the maps that I was able to access and there is no “.git” folder in there either nor anything that sounds related to “perforce” or “plastic”. I’ve asked my teammate as well if they know and they said they aren’t sure.

The one part you mentioned “Reconnect Source Control in Project Browser” I checked in the project browser and the “Source Control button at the bottom left of the project browser” is not there, its the “Editor Preferences”.

Thanks!
