Setting Up the ChunkDownloader Plugin

Setting up a local host web site


The ChunkDownloader patching system is a built-in plugin for Unreal Engine that provides patching functionality. This guide will walk you through setting up the plugin so that you can use it in your game's code.

Required Setup

To use ChunkDownloader, you must be working with a C++ project. If you are using a Blueprint project, you can create a new C++ class to convert it into a C++ project.


  1. Open your Project Settings, navigate to Project > Packaging, then make sure that Use Pak File and Generate Chunks are both enabled.


  2. Open the Plugins window and enable the Chunk Downloader plugin. Restart the editor for your changes to take effect.


  3. In Visual Studio, open your project's Build.cs file and add ChunkDownloader to your ModuleRules as private dependency module names.

  4. Save your changes to these files.

  5. Right-click on your .uproject file and click Generate Project Files.


  6. Return to your project's solution in Visual Studio, then build the project.

Final Result

Now that ChunkDownloader is available to use in your project, you can proceed with implementing them in your game's code to download and mount .pak files.
