Day Settings

Day Sky

This documentation provides a brief overview of the different Controls available in the True-Sky add-on for Blender. Please note that this is not a tutorial but rather a summary of the Controls to help you understand what each one does. For detailed tutorials, you can visit our YouTube Channel here.

True-Sol

Sol Settings

True-Sol represents the primary star in the True-Sky system. It offers options to simulate various controls found in other sky simulation tools. These settings are based on real-world values to accurately replicate phenomena such as dust, air thickness, and sun position.

Sol Controls

Place sun by Clicking: Set the position of the sun in the world shader by clicking in the viewport.

Enable Sun Position: Enable and use the Sun Position addon to correctly place the True-Sol sun in the sky. While enabled True-Sol's Height and Rotation cannot be manually edited. Disabling will keep settings from Sun Position

Use Sun Lamp: Enable and use Sun lamp to correctly place the True-Sol sun in the sky. While enabled True-Sol's Height and Rotation cannot be manually edited. Disabling will keep settings from Sun Position

Size: Adjusts the diameter of the sun (default: 0.545, representing the size of our Sun as seen from Earth)

Intensity: Controls the intensity of the sunlight

Height: Changes the sun's elevation in degrees (up to 90 degrees)

Rotation: Alters the rotation (azimuth) of the sun (-360 to 360 degrees)

Sky Strength: Adjusts the lighting strength of the sky

Air: Controls the thickness of the atmosphere

Dust: Changes the amount of dust in the atmosphere, affecting sunlight transmission

Ozone: Increases or decreases the amount of ozone in the atmosphere, influencing the color of the sky

Sol HSV

Sol Hue/Saturation/Value settings

True-Sol HSV settings allow you to adjust the color values of the sky and sun. These settings affect the entire atmosphere, not just the sunlight.

HSV Controls

Use HSV Toggle: Enables the options to adjust the hue, saturation, and value of the sun

Hue: Changes the hue of the sun and sky

Saturation: Adjusts the saturation of the sun and sky

Value: Controls the lightness or darkness of the sun and sky

True-Binary

Binary Settings

True-Binary represents the secondary star in the True-Sky system. It offers options that are not typically found in other sky simulation tools. Enabling the Binary option allows you to simulate a second sun or sister star in a solar system.

Binary Controls

Enable Binary Toggle: Enables a secondary star

Size: Adjusts the diameter of the binary star

Intensity: Controls the intensity of the binary star's light

Height: Changes the elevation of the binary star

Rotation: Alters the rotation (azimuth) of the binary star

Sky Strength: Adjusts the strength of the binary star's lighting

Air: Controls the thickness of the atmosphere

Dust: Changes the amount of dust in the atmosphere

Ozone: Increases or decreases the amount of ozone in the atmosphere, influencing the color of the sky

Colour change Toggle: Enables the option to change the color of the binary star and sky

Colour: Adjusts the color of the binary star and sky using an RGB picker

Binary HSV

Binary Hue/Saturation/Value settings

True-Binary HSV settings allow you to adjust the color values of the sky and binary star. Similar to Sol HSV, these settings affect the entire atmosphere.

Binary HSV Controls

Use HSV Toggle: Enables the options to adjust the hue, saturation, and value of the binary star

Hue: Changes the hue of the binary star

Saturation: Adjusts the saturation of the binary star

Value: Controls the lightness or darkness of the binary star

True-Haze

True-Haze Volumetric Settings

True-Haze represents a volumetric layer that simulates particles and pollutants in the atmosphere. It creates effects such as the "washed-out" appearance of distant objects and the glare/glow effect around light sources.

Haze Controls

Use Haze Toggle: Enables the addition of haze to the atmosphere

Sky Colour: Changes the color of the sky using an RGB picker

Horizon Colour: Changes the color of the horizon using an RGB picker

Pollution: Increases or decreases the level of pollution in the atmosphere

Height: Changes the height of the haze in the atmosphere

Distance from Camera: Adjusts the distance of the haze from the camera

Scattering: Changes the thickness of the haze, affecting the density of volumetrics

Anisotropy: Higher values create a glow effect around strong light sources, while lower values simulate a clear atmosphere (average for Earth is around 0.7)

Enhanced GodRays: Changes the strength of the god rays

GodRay Colour: Adjusts the color of the god rays

True-Fog

True-Fog Settings

True-Fog represents a volumetric layer that simulates water molecules in the atmosphere. It creates a thick layer that can obstruct light and make distant objects difficult to see. Dense fog can even block out the sky.

Fog Controls

Use Fog Toggle: Enables the addition of fog to the atmosphere

Fog Colour: Changes the color of the fog using an RGB picker

Shadow Colour: Adjusts the color of the shadows using an RGB picker

Air Quality: Changes the quality of the air

Height: Changes the height of the fog in the atmosphere

Distance from Camera: Adjusts the distance of the fog from the camera

Scattering: Changes the thickness of the fog, affecting the density of volumetrics

Anisotropy: Higher values create a glow effect around strong light sources, while lower values simulate a clear atmosphere (average for Earth is around 0.7)

Presets

Presets provide pre-built sky setups to simplify the initial setup process. These pre-set skies can be used when you need to quickly set up a specific sky type.

Functions

Select a Preset: Choose a preset sky, and the world shader will automatically update to the selected configuration.
