🧠 Property Transfer Manager Tool (PTMTool) for Unreal Engine

A powerful and intuitive Unreal Editor plugin that enables fast and reliable copying of properties, functions, and macros between Blueprints. This tool significantly improves productivity in complex Blueprint-based projects.

✨ Features

• 🔁 Copy properties from one Blueprint to another
• 📌 Preserve variable values, including arrays and structs
• 🚫 Clash detection for conflicting names or types
• 📚 Supports macros and function graphs
• 🎨 UI-based selection with color-coded type indicators
• 🔍 Filter and inspect Blueprint properties easily
• 📁 Transfer variables to and from User Defined Structs

🚀 Getting Started

🧩 Installation

1. Place the PTMTool plugin folder inside your project’s Plugins/ directory.
2. Regenerate project files and recompile (for C++ projects).
3. Launch the Unreal Editor.
4. Focus the Editor on the Map Editor window (not Blueprint windows).
5. Open Tools > Property Copy... or Tools > Function Copy... to access the tool.

Compatible with Unreal Engine 4.XX and potentially UE5 with minor adjustments.

🖥️ How to Use

1. Open the Property Transfer Manager window from the Unreal Editor.
2. Select your Source and Target Blueprints.
3. Use the property/function picker to select which elements to transfer.
4. Press Apply to complete the transfer.

✅ Supported Types
