3D Sky: What Is It and Why You Should Try It
Have you ever wondered what it would be like to see the sky in three dimensions? To feel like you are flying among the clouds, stars, and planets? To create your own custom sky scenes with realistic lighting, shadows, and movement? If so, then you might be interested in learning more about 3D sky.
3D sky is a term that refers to any representation of the sky that uses three-dimensional graphics, models, or effects. Unlike traditional 2D sky images or videos, which are flat and static, 3D sky can create a sense of depth, perspective, and dynamism. You can use 3D sky for various purposes, such as enhancing your visual experience, expressing your creativity, or telling a story.
3d sky
In this article, we will show you some examples of how you can use 3D sky in different ways. We will also teach you how to create and animate your own 3D sky using Adobe After Effects, a popular software for motion graphics and visual effects. Finally, we will share some tips on how to find and use free 3D sky models and wallpapers for your projects.
How to Create and Animate 3D Sky in After Effects
One of the easiest and most versatile ways to create your own 3D sky is by using After Effects. After Effects is a software that allows you to create stunning animations, effects, and compositions using layers, keyframes, expressions, and plugins. You can use After Effects to create realistic or stylized clouds, stars, planets, sunsets, rainbows, auroras, and more.
To create a basic 3D cloud animation in After Effects, you will need to follow these steps:
Creating Your Shape Mask
The first step is to create a shape mask that will define the outline of your cloud. To do this, you will need to:
Create a new composition with the dimensions and duration of your choice.
Create a new solid layer with any color and name it "Cloud".
Select the Ellipse Tool from the toolbar and draw a large oval on the solid layer. This will create a mask on the layer.
Open the Mask properties of the layer and set the Feather to a high value, such as 200 pixels. This will create a soft edge around the mask.
Adjust the Mask Expansion to a negative value, such as -50 pixels. This will create some space around the edge of the mask.
You should now have a shape mask that looks like a fluffy cloud.

Creating a Moving Cloud
The next step is to add some texture and movement to your cloud. To do this, you will need to:
Select the Cloud layer and go to Effect > Distort > Turbulent Displace. This will add some noise and distortion to the layer.
Adjust the Amount and Size of the effect to create some variation in the shape of the cloud. You can also change the Complexity and Evolution settings to change the look of the noise.
To make the cloud move, you will need to use expressions. Expressions are snippets of code that can control various properties of your layers. To add an expression, hold down Alt (Windows) or Option (Mac) and click on the stopwatch icon next to any property.
To make the cloud move horizontally, you will need to add an expression to the Offset Turbulence property of the Turbulent Displace effect. The expression should look something like this: [time * 50, value[1]]. This means that the x value of the offset will increase by 50 pixels per second, while the y value will remain unchanged.
To make the cloud move vertically, you will need to add an expression to the Position property of the Cloud layer. The expression should look something like this: [value[0], 540 + Math.sin(time) * 50]. This means that the x value of the position will remain unchanged, while the y value will oscillate between 490 and 590 pixels, creating a sinusoidal motion.
You should now have a moving cloud that looks more realistic and dynamic. Adding Controls for Multiple Clouds
The final step is to add some controls that will allow you to create and adjust multiple clouds in your composition. To do this, you will need to:
Select the Cloud layer and go to Layer > Pre-compose. Name the new composition "Cloud Precomp" and make sure to move all attributes into the new composition.
Open the Cloud Precomp and go to Composition > Composition Settings. Change the duration to 10 seconds and click OK.
Select the Cloud layer and go to Layer > Time > Enable Time Remapping. This will allow you to change the speed and duration of the layer.
Add an expression to the Time Remap property of the Cloud layer. The expression should look something like this: loopOut("cycle"). This means that the layer will loop indefinitely, creating a seamless animation.
Go back to the main composition and duplicate the Cloud Precomp layer as many times as you want. You can rename each layer to keep track of them.
Select each Cloud Precomp layer and adjust the following properties: Scale, Position, Rotation, and Opacity. You can use different values for each layer to create some variation and depth in your sky scene.
You should now have a 3D sky with multiple clouds that you can customize and animate as you wish.
How to Use 3D Sky Models in Your Projects
If you want to create more complex or realistic 3D sky scenes, you might want to use 3D sky models instead of 2D layers. 3D sky models are digital representations of the sky that use polygons, vertices, edges, faces, and textures. You can use 3D sky models to create stunning images or videos of the sky with different elements, such as mountains, trees, buildings, birds, planes, etc.
To use 3D sky models in your projects, you will need to follow these steps: Where to Find Free 3D Sky Models Online
