Paint Your Own Sky: The Magic of Sky Atmosphere

Have you ever looked up and wondered why the sky is blue? Or why it turns orange at sunset? In Fortnite, you can paint the sky yourself! You can make it purple, green, or even red.

In this tutorial, we will learn how to use the Sky Atmosphere. This is a special tool that changes the look of the distant sky. It acts like a giant canvas behind your island. We will use it to create a magical alien world. By the end, you will have a custom sky that matches your game mood.

What You'll Learn

• What a Sky Atmosphere is and why it matters.
• How to change the Sky Gradient colors.
• How to adjust the Sun to make it bigger or brighter.
• How to build a simple alien planet scene.

How It Works

Think of your Fortnite island like a stage in a theater. The stage has a floor, some props, and actors. But what about the background? If the background is just a flat gray wall, it looks boring. The Sky Atmosphere is like a giant, beautiful painting behind the stage.

This painting has three main parts. We call these parts a Gradient. A gradient is a smooth blend from one color to another.

1. Low Color: This is the color near the horizon. It looks like the bottom of the sky.
2. Mid Color: This is the color in the middle of the sky.
3. High Color: This is the color at the very top. It looks like space.

You can also change the Sun. The sun is the bright ball of light in the sky. You can make it tiny and dim, or huge and bright. This changes how your whole island looks.

When you change these settings, you are not changing the ground. You are only changing what players see in the distance. It sets the mood for your entire game.

Let's Build It

We will create an "Alien Sunset" scene. We will make the sky pink and purple. We will also make the sun big and orange.

First, open UEFN. Create a new island. Add some ground so you have something to look at. Now, we need to add the Sky Atmosphere.

In UEFN, the Sky Atmosphere is often part of the Environment Light Rig. This is a special device that controls lighting for the whole map. Find it in the editor. Place it anywhere on your map. It does not matter where. It affects the whole world.

Now, look at the details panel on the right side. You will see options for the Sky Atmosphere. Let’s change them step-by-step.

Here is the code-like logic for what we are doing. Verse is the language we use to make things happen, but for setting up the sky, we use the editor tools. However, understanding how the computer sees this helps. The computer sees the sky as a big sphere around us.

// This is a conceptual look at how the sky is set up.
// We are setting colors for different heights.

// 1. Set the bottom of the sky to Pink
Sky_Low_Color := <Color: Pink>

// 2. Set the middle of the sky to Purple
Sky_Mid_Color := <Color: Purple>

// 3. Set the top of the sky to Dark Blue (like space)
Sky_High_Color := <Color: Dark Blue>

// 4. Make the Sun big and bright
Sun_Size := 1.5 // Bigger than normal
Sun_Color := <Color: Orange>

Let’s break down what this means in the editor.

Step 1: Change the Sky Gradient. Find the "Sky Gradient" section.

• Set Sky Gradient Low Color to Pink.
• Set Sky Gradient Mid Color to Purple.
• Set Sky Gradient High Color to Dark Blue.
• Make sure Sky Gradient Blend is set to 1. This means we use our colors fully.

Step 2: Change the Sun. Find the "Sun" section.

• Set Sun Size to 1.5. This makes the sun disk larger.
• Set Sun Color to Orange.
• Set Sun Intensity to a high number, like 10. This makes it very bright.

Step 3: Test it. Play your game! Look up. Do you see the pink and purple sky? Does the big orange sun look cool? You just painted the sky!

Try It Yourself

Now that you know how to change the sky, try this challenge.

Challenge: Make a "Night Sky" for a spooky island.

Hint:

• Change the High Color to black or very dark blue.
• Change the Mid Color to a dark gray.
• Change the Low Color to a deep purple.
• Turn down the Sun Intensity so it is dark.

Can you make it look like midnight?

Recap

You learned how to use the Sky Atmosphere to change the look of your island. You changed the Sky Gradient colors to make a smooth blend from bottom to top. You also adjusted the Sun size and color. These tools let you set the mood for your game. You are now a sky painter!
