Theme Engine Pro

Overview

Theme Engine Pro is an Unreal Engine editor plugin for styling the editor with themes, color controls, Blueprint graph customization, and font selection.

Download and Install

You can install the plugin from Fab through the Epic Games Launcher.

After installing:

1. Open your Unreal project.
2. Enable the plugin if it is not already enabled.
3. Restart the editor when prompted.

Open the Plugin

In Unreal Editor, open the plugin from the top menu bar:

• Tools > Theme Engine Pro

You can also access it from the plugin tab once it is open.

How It Works

Theme Engine Pro uses a profile-based workflow:

• Built-in templates are read-only starting points.
• Custom themes are editable profiles.
• Changes are applied when you press Apply Theme.
• You can save the current custom state as a reusable profile.

This keeps the workflow predictable and avoids changing the built-in templates directly.

Main Workflow

1. Choose a theme

In Theme Library, select one of the built-in templates such as:

• Default UE5 Dark
• Midnight AMOLED
• Cyberpunk Edge
• Godot Classic

2. Create a custom theme

Use one of these actions:

• Create Theme to start from the internal blank base.
• Duplicate Template to copy the selected preset into a new custom theme.

3. Edit the theme

Use the left-side sections to adjust the editor:

• Global Colors
• Blueprint Graph
• Font Customization

4. Apply the theme

Press Apply Theme to push the current profile into the editor.

5. Save the theme

Use Save Profile As... to keep the current theme as a reusable custom profile.
