PanoramaSkyMaterial in Godot – Complete Guide

Welcome to this detailed tutorial where we explore the world of PanoramaSkyMaterial in Godot 4. Often, the impact of a game’s environment is underestimated. However, a captivating background can significantly enhance the player’s immersion in a game. Learning how to implement panoramic skies can be a game-changer for your projects, and that’s precisely what we will delve into today. Whether you’re beginning your journey in game development or looking to add another skill to your repertoire, understanding how to use PanoramaSkyMaterial is both interesting and beneficial.

What is PanoramaSkyMaterial?

PanoramaSkyMaterial is a resource in Godot 4 used in conjunction with the Sky node. It allows for the rendering of panoramic backgrounds, providing a way to create beautiful and expansive skies in your game scenes. These backgrounds are not just static images but can interact with environmental lighting and reflect on different surfaces, giving scenes a more dynamic and realistic feel.

What is it for?

This kind of material is utilized to create sky domes or skyboxes which are integral parts of outdoor scenes. Instead of using the traditional cubemap format, however, PanoramaSkyMaterial works with an equirectangular sky map. This format efficiently wraps around the entire scene, offering a seamless background experience. Such a feature is perfect for games that emphasize the open-world experience or any game where the sky’s appearance can influence the game’s aesthetic and mood.

Why Should I Learn It?

Having the ability to create your own panoramic skies opens up a world of creative possibilities. Panoramic sky backgrounds are essentially your canvas where you can paint the mood of your game – be it the calm of a serene sunset or the ominous approach of a storm. Learning how to use PanoramaSkyMaterial in Godot not only enhances the visual appeal of your games but also gives you more control over the game environment, making it an indispensable skill for aspiring and seasoned game developers alike. Let’s get started on our journey to mastering panoramic skies in Godot 4!

Setting Up the Environment

Before diving into the PanoramaSkyMaterial, we need to set up a basic environment in Godot 4. We start by creating a new scene with a WorldEnvironment node:

var environment =

After adding the WorldEnvironment node to our scene, its Env resource must be configured to include the PanoramaSkyMaterial settings.

var env =
environment.environment = env

With our environment ready, we are now set to begin tinkering with PanoramaSkyMaterial.

Creating and Assigning PanoramaSkyMaterial

Now that we have our WorldEnvironment node ready, let’s create and assign a PanoramaSkyMaterial to it. To do this, we’ll create a new Sky object and PanoramaSkyMaterial, then set it as the Sky’s Panorama.

var sky =
var panorama_sky_material =

// Assign the sky material to the sky resource  
sky.sky_material = panorama_sky_material

// Now set our WorldEnvironment's sky property
env.background_sky = sky

Be sure to have a panoramic image ready, as it will be needed in the next step to create our sky texture.

Loading and Using a Panoramic Image

Having created the PanoramaSkyMaterial, we’ll need to load a panoramic image to use as our sky. This should be an equirectangular format image that we can set as the panorama texture.

var panorama_texture = load("res://path_to_your_panorama_image.jpg")

// Once loaded, assign the texture to our panorama sky material
panorama_sky_material.panorama = panorama_texture

This will apply the panoramic image onto our sky dome in the scene. If all goes well, you should see your panoramic image wrapped around your environment as the background.

Adjusting PanoramaSkyMaterial Properties

To make the most of our PanoramaSkyMaterial, we can fine-tune various properties such as the rotation and exposure to fit our scene perfectly.

Adjusting the horizontal rotation of the sky to align with your level design can help in achieving the desired ambiance. Also, setting its exposure can allow for the sky to be brighter or darker depending on the time of day you want to simulate.

// Rotate the sky 45 degrees to the right
panorama_sky_material.rotation = 45.0

// Adjust exposure to simulate a brighter day
panorama_sky_material.exposure = 1.2

These are just examples of the adjustments you can make to the PanoramaSkyMaterial to better suit your game’s visuals.

We’ve covered the necessary basics to get you started with PanoramaSkyMaterial in Godot 4. Stay tuned for the next part where we’ll take things further, exploring how to animate sky properties and integrate the sky with environmental effects for a truly dynamic environment.

Remember that, at Zenva, we provide detailed tutorials and courses covering various aspects of game development. Our aim is always to help you learn and create with confidence. Stay with us as we continue to explore the potentials of Godot 4 and PanoramaSkyMaterial, building the skills that can bring your game worlds to life.Now that we have our panoramic sky in place and we’ve learned how to adjust its basic properties, it’s time to explore some advanced techniques to bring our skies to life.

Animating the Sky Rotation

To add dynamism to our sky, we might want to animate its rotation, simulating the passage of time. To achieve this, we’ll use Godot’s built-in scripting capabilities.

func _process(delta):
    panorama_sky_material.rotation += 10 * delta
    if panorama_sky_material.rotation >= 360:
        panorama_sky_material.rotation = 0

In the script above, we make the sky rotate slowly by increasing the rotation property each frame. The sky will keep rotating, making a full rotation once it hits 360 degrees.

Changing Sky Textures Dynamically

Next, let’s look at a way to change the sky’s texture based on certain game conditions, like transitioning from day to night.

func change_sky_texture_to_night():
    var night_texture = load("res://path_to_your_night_panorama_image.jpg")
    panorama_sky_material.panorama = night_texture

With this function, you could trigger a shift from a daytime sky to a nighttime one, enhancing the realism and immersion of your game environment.

Integrating Sky with Environmental Lighting

A sky is not just for show; its lighting should affect the entire scene. We can make sure the environmental lighting updates based on the sky’s exposure, providing a cohesive visual experience.

func _process(delta):
    env.adjustment_enabled = true
    env.adjustment_brightness = panorama_sky_material.exposure

This code snippet demonstrates how to link the environment’s brightness setting to the exposure of the PanoramaSkyMaterial, ensuring that changes in the sky’s brightness are reflected across the entire scene.

Custom Shader Effects on PanoramaSkyMaterial

For those looking to really push the envelope, Godot’s shading language opens up a world of possibilities. Here, we’ll add a custom shader that introduces animated clouds to our sky.

shader_type canvas_item;

void fragment() {
    // Your shader code for animated clouds goes here
    // ...

Applying a shader to the PanoramaSkyMaterial can result in sophisticated effects like moving clouds or shifting celestial bodies, adding yet another layer of depth and engagement to your game’s environment.

Handling Sky Reflections

Lastly, we want to ensure that our sky is influencing reflections properly. This is particularly important for materials with reflective properties in our scene, like water or metallic surfaces.

env.background_sky_custom_fov = 100
env.background_sky_orientation = Quat(Vector3(1, 0, 0), deg2rad(45.0))
env.background_mode = Environment.BG_SKY

The above code sets a custom field of view for the sky reflection and an orientation for how the sky should be mapped for reflections.

By now, you should have a good grasp on how to implement and enhance PanoramaSkyMaterial within Godot 4, creating more dynamic, engaging skies that react to and influence the game world. There’s much to explore and many ways to refine your sky environments, so take these snippets as starting points for your own creative implementations.

At Zenva, we encourage you to experiment, iterate, and refine your skills. Keep honing your craft, and remember that every detail, like the sky overhead, contributes to creating immersive, memorable gaming experiences. Happy developing!As we continue to enrich our skies in Godot 4, let’s delve into advanced interactions such as changing the sky based on the player position and time of day, as well as debugging tips to ensure your panoramic skies look just right.

Dynamic Sky Changes Based on Player Position

Imagine a game where the sky changes as the player moves through different zones—desert to snowfields, for instance. We can achieve this by checking the player’s position and updating the sky material accordingly.

func update_sky_based_on_position(player_position):
    if player_position.x > 1000:  // Example threshold for changing sky
    elif player_position.x < 1000:

func change_sky_texture(sky_path):
    var new_sky_texture = load(sky_path)
    panorama_sky_material.panorama = new_sky_texture

This function would be called regularly, checking the player’s coordinates and swapping out the sky textures dynamically.

Time-Based Sky Transitions

To simulate the passage of time, you could interpolate between different sky textures, like dawn to daylight to dusk.

var day_sky = load("res://day_sky.jpg")
var night_sky = load("res://night_sky.jpg")

func interpolate_sky_transition(time_of_day):
    panorama_sky_material.panorama = day_sky.interpolate_with(night_sky, time_of_day)

# Call this in your game loop, with time_of_day varying between 0.0 (day) and 1.0 (night)

The `interpolate_with` method linearly interpolates between two textures, creating a smooth transition effect from day to night.

Adjusting Sky Parameters in Real-Time

Debugging and perfecting your sky often involves tweaking parameters while the game is running. Using Godot’s built-in remote scene tree while the game is running, you can adjust the PanoramaSkyMaterial parameters in real-time.



Optimizing Performance

While panoramic skies are beautiful, they can be demanding on performance. To get the best results without sacrificing frame rates, consider reducing the resolution of your sky textures where appropriate and enabling mipmaps.

var sky_texture = load("res://your_panoramic_image.jpg")
sky_texture.flags |= Texture.FLAG_MIPMAPS

panorama_sky_material.panorama = sky_texture

# This can help with improving performance, especially on lower-end hardware

The `FLAG_MIPMAPS` flag ensures that smaller, less detailed versions of the texture are used when the texture is seen from far away.

Simulating Weather Changes

Another compelling feature would be to simulate weather changes in your panoramic sky. This involves more than just changing textures; you might want to also modify environment settings like fog.

func update_weather_condition(is_raining):
    if is_raining:
        env.glow_enabled = false
        env.fog_enabled = true
        env.fog_color = Color(0.5, 0.6, 0.7)
        env.fog_depth_begin = 50
        env.glow_enabled = true
        env.fog_enabled = false

This script would toggle fog on and off in the game world, simulating the onset of rain or a clearing sky.

By applying these techniques, you will be able to create skies that not only look fantastic but are also deeply integrated into your game’s mechanics and storytelling. Remember, it’s often these nuanced touches that can transform a good game into a great one. Keep experimenting with these strategies to find the perfect balance for your game’s sky. Enjoy the process and watch your game world come alive!
