Smooth UI Fade Animation in Unreal Engine is one of the simplest ways to improve your game’s user experience while keeping your interface clean and modern. In this beginner-friendly tutorial, you’ll learn how to create professional fade-in and fade-out effects using Unreal’s UMG system and Blueprint logic—no coding required.
We’ll guide you step-by-step to animate widgets, trigger transitions with keyboard input, and manage input modes to ensure a polished and seamless result. Whether you’re building a pause menu, inventory, or dialogue box, these techniques are reusable across any project.
Why it matters:
Smooth UI transitions reduce visual clutter, improve clarity, and make your interface feel responsive and immersive. Because everything is handled in Blueprints, it’s accessible to artists and designers—not just programmers.

🎯 What You’ll Learn
- How to use Widget Blueprints to build clean UI structure.
- Creating fade-in and fade-out animations using render opacity tracks.
- Triggering UI with keyboard input.
- Handling input modes and cursor visibility for seamless user experience.
- Making the UI system reusable for menus, dialogs, and other interfaces.
🛠 Step-by-Step Breakdown
1. Create the Widget Blueprint
Start by creating a new Widget Blueprint. We name it something like WBP_Menu. Add a Canvas Panel and make sure it fills the screen.
2. Build the Menu UI
Add a Size Box to represent your menu panel. Set its alignment to 0.5 (centered), and size it to something like 600×300. Inside it, nest another Canvas Panel and then:
- Add an Image for the background (set it to semi-transparent gray).
- Add a Button with Text inside it (like “Exit”).
3. Animate Fade In
- Open the Animations tab in the Widget Blueprint.
- Create a new animation called Fade In.
- Track the Render Opacity of the Size Box: set keyframes at 0 seconds (opacity 0) and 1 second (opacity 1).
4. Animate Fade Out
- Create a second animation called Fade Out.
- Again, track Render Opacity, but this time:
- 0 seconds: opacity 1
- 1 second: opacity 0
5. Auto-Play Fade In on Construct
Inside the Graph tab of the widget, use the Event Construct node to play the Fade In animation when the UI is shown.
6. Trigger Menu with Keyboard
Inside your character Blueprint (e.g., ThirdPersonCharacter):
- Create a key input event (like H).
- Use a FlipFlop to toggle:
- Create widget, Add to viewport, set Input Mode UI+Game, and Show Mouse Cursor.
- On second press: Play Fade Out, Delay, then Remove from parent, and restore Game Only Input Mode.

💡 Where You Can Use This
This fade animation technique is not just for one type of menu — it’s a reusable and modular system that works in many areas of your game. It adds polish and clarity to your interface and elevates player experience by offering smooth transitions.
Here are some examples where you can use it:
- Pause Menus – Instantly bring up a centered menu with a soft fade-in and clean fade-out when resuming the game.
- Dialog Windows – Display conversations or quest prompts in a way that doesn’t feel jarring or rushed.
- Inventory Screens – Open item menus with a subtle fade to keep the visual flow of your game smooth.
- Settings Panels – Add a layer of professional feel when transitioning to and from options or controls menus.
- Main Menus and Splash Screens – Make your opening interface feel more refined and interactive with simple fades.
- Any temporary UI popups or overlays – Perfect for tutorials, tooltips, warnings, or in-game feedback windows.
You can apply this same logic to any UMG-based widget and reuse it across all your game UI needs — no extra setup required each time.
🧠 Why This Is Useful
Smooth transitions improve user experience and make your game feel more professional. This method avoids code and works entirely in Blueprint, making it accessible to artists, designers, and developers alike.
