Compiling Unreal Engine
Note: As of 2020-05-05, you need ~120GB of disk space for a compiled version of the Unreal Engine.
- Step 1: Get access to the Unreal Engine source code.
- You must be an Unreal Engine subscriber (if not, open an account there: https://www.unrealengine.com)
- You must have a GitHub account (if not, open an account there: https://github.com)
- Have associated your GitHub account with your Unreal Engine account as described on the UE4 on GitHub page.
- At this point you should be able to access the Unreal Engine repository on GitHub.
- Step 2: Get the Unreal Engine source code.
- Get the source code with: git clone -b 4.24.3-release https://github.com/EpicGames/UnrealEngine.git.
- This will create an "Unreal Engine" sub-directory where you run the command.
- Step 3: Install the latest version of Xcode.
- Install the latest version of Xcode.
- Step 4: Prepare the Xcode workspace.
- In the UnrealEngine directory, run the script Setup.command. It downloads 11.5GB of dependencies and may take a while.
- At the same location, run the script GenerateProjectFiles.bat. It generates the UE4.xcworkspace Xcode workspace.
- Step 5: Compile Unreal Engine with Xcode.
- Load the UE4.xcworkspace into Xcode.
- Select the ShaderCompileWorker > My Mac target in the title bar, then build with Product > Build menu item.
- Wait for the build to complete.
- Select the UE4 > My Mac target, and build again.
- Compiling may take a long time, depending on your system specs.
- After the compilation finishes, select the 'Product > Run' menu item to load the editor.
