Unreal Revision Control Command Line Interface

The Unreal Revision Control (URC) Command Line Interface (CLI) enables you to perform revision control actions on your project using a third-party command line tool such as PowerShell. Although these actions can often be performed with the user interface, some allow you to go beyond what the interface currently supports.

This document provides an overview of:

• How to get started with CLI

• Common use cases and how to achieve them with the CLI

Before You Start

To use command lines you need to know where the URC files are located in Windows Explorer and set up an environment variable to create and use command lines with URC.

Before setting the environment variable, make sure to set your folder where the urc.exe exists within your path variable.

1. Open your Windows settings and select System > About > Advanced system settings. The System Properties panel opens.

2. Click Environment Variables…

   Your name appears after C:\Users\

4. Select Browse and choose the file path that leads to your urc.exe files.  This can usually be found at C:\Program Files\Epic Games\Fortnite\FortniteGame\Binaries\Win64

   

5. Click OK until all the open panels are closed.

You’ve successfully edited an environment variable.

Launching PowerShell

Open the Unreal Editor for Fortnite (UEFN) project you’re working on with Windows Explorer.

Make sure to log into UEFN first before using other URC CLI commands.

This depends on whether you have recently logged into UEFN. You won’t need to call urc auth login if UEFN is open and you’re logged in unless the token expires. If you use the CLI without UEFN open or after the token expires, you’ll have to log into the CLI.

1. Shift + right-click to open the contextual menu.

2. Choose Open PowerShell window here.

Copy and paste the Plugins folder to your desktop to keep a backup of your assets.

Afterward, sync back to the latest snapshot.

Once you've successfully synched the project to the latest snapshot, do the following:

1. Delete Plugins from your current UEFN project folder.

2. Copy and paste the previous Plugins folder from the desktop into the project folder.

3. Open your project in UEFN and confirm the state of the project looks as you intend it.

4. Click Check In Changes if you project looks as you expect to create a new snapshot reflecting the new state of your project.
