mod.io Unreal Engine Component UI Plugin

Welcome to the mod.io Unreal Engine Component UI repository. The Component UI plugin provides UI components, a template Mod Browser, and editor tooling to allow UE developers to rapidly implement mod.io-aware mod browsing and other elements into their game’s UI. It can be added either directly into existing screens or in dedicated browser and discovery sections.

Engine & Platform Compatibility

This plugin requires the core mod.io plugin to be installed alongside it. Support for both plugins is generally maintained to support the 3 most recent versions of Unreal Engine. === Engine compatibility

Engine Version	Last Release
UE5.2	Current
UE5.3	Current
UE5.4	Current

Features

• UI-focused subsystem easing communication between UI elements and the core plugin

• Default UI component implementations that utilize the subsystem and visualize common mod.io data structures

• Interfaces and specifications to allow you to implement your own compliant components

• Template/reference implementation of a mod browser suitable for use as the basis of your own UI

• Permissive MIT/BSL-license

Installation

Prerequisites

1. This plugin relies on the mod.io core plugin, available at https://github.com/modio/modio-ue. Please ensure you have downloaded and installed and configured the plugin prior to installing the Component UI plugin.

2. To use this initial release of the Component UI plugin, you will need to remove our Legacy UE5 UI from the core plugin. Please delete the following folders from the core plugin’s directories before proceeding:

   • Modio/Source/ModioUI

   • Modio/Source/ModioUICore

   • Modio/Source/ModioUIEditor

   • Modio/Content/UI5

3. Please remove the ModioUI, ModioUICore and ModioUIEditor module elements from Modio/Modio.uplugin file

Note	The Legacy UE5 UI will be migrated to its own dedicated repository in the future - after that point, this manual cleanup will no longer be required.

Adding plugin files to your project

As a git submodule

1. Add this repository as a submodule to your repository in your project’s Plugins/ModioComponentUI directory

   In the directory with your .uproject file: git submodule add https://github.com/modio/modio-ue-component-ui Plugins/ModioComponentUI

2. Initialize our submodules with git submodule update --init --recursive

In a non-git project, or without submodules

1. Grab the latest release zip from the Releases section on this page, and extract the contents to your project’s Plugins/ModioComponentUI directory

Note	The automatically generated zips on the release page and the 'Code' dropdown on this page will not work if this repository adds submodule dependencies in future releases. Please use the attached archive on the release instead.
