Unreal-Engine-Plugin-Builder

A simple GUI tool for rebuilding UE plugins on Windows using RunUAT

What is this?

This is a small desktop app that makes it easier to rebuild Unreal Engine plugins for different engine versions. I made it to simplify my own workflow when working across multiple UE versions.

Features

• Rebuild plugins between different UE versions
• Auto-detects installed Unreal Engine versions (or add them manually)
• Configure build platforms, options, and parameters
• Real-time build console with syntax highlighting
• English and Russian language support
• Dark theme UI for late-night coding sessions

Installation

Quick Start

1. Download the release ZIP
2. Extract anywhere on your PC
3. Run UEPluginBuilder.exe

That's it! No installation needed.

For Developers

If you want to run from source:

1. Make sure you have Python 3.8+ and PySide6
2. Clone this repo
3. Run python main.py

How to Use

Basic Steps

1. Select your plugin: Browse to a .uplugin file or drag-drop it into the app
2. Choose target UE version: Select which engine version to rebuild for
3. Set output: Either use default location or choose custom directory
4. Build: Hit the "Build Plugin" button and watch the console

Advanced Stuff

Click "Advanced Options" to:

• Select target platforms (Win64, Win32, Mac, Linux)
• Configure build parameters
• Add/scan Unreal Engine installations
• Change interface language

Settings

The app saves its config in:
%LOCALAPPDATA%\UnrealPluginRebuilder\

Troubleshooting

No Engines Found?

Use "Advanced Options > Add Unreal Engine..." to manually add your UE installation.

Build Errors?

Check the console output for error messages. Make sure your plugin is compatible with the target engine version.
