The Sky Texture node generates a procedural sky. It’s typically used in combination with the World Output Node.

Inputs – Уводи

Vector – Вектор

Текстурна координата для відбору текстури; стандартно використовуються генеровані – Generated текстурні координати, якщо цей роз’єм залишається ні з чим не з’єднаним.

Properties – Властивості

Тип Неба – Sky Type

Модель неба для використання.

Preetham

Based on the 1999 paper by Preetham et al.

Hosek/Wilkie

Based on the 2012 paper by Hosek and Wilkie.

Note that this sky type is quite bright and makes the image look overexposed with the default scene settings. You can reduce the Exposure setting in Properties ‣ Render ‣ Film to fix this.

Напрям Сонця – Sun Direction

Вектор напряму сонця.

Мутність – Turbidity

Мутність атмосфери.

• 2: як Арктичне

• 3: чисте небо

• 6: теплий/вологий день

• 10: туманний день

Альбедо Поверхні землі – Ground Albedo

Amount of light reflected from the planet surface back into the atmosphere.

Sun Disc Cycles Only

Enable/Disable sun disc lighting.

Sun Size

Angular diameter of the sun disc (in degrees).

Sun Intensity

Multiplier for sun disc lighting.

Sun Elevation

Rotation of the sun from the horizon (in degrees).

Sun Rotation

Rotation of the sun around the zenith (in degrees).

Altitude

The distance from sea level to the location of the camera. For example, if the camera is placed on a beach then a value of 0 should be used. However, if the camera is in the cockpit of a flying airplane then a value of 10 km will be more suitable. Note, this is limited to 60 km because the mathematical model only accounts for the first two layers of the earth’s atmosphere (which ends around 60 km).

Air

Density of air molecules.

• 0 no air

• 1 clear day atmosphere

• 2 highly polluted day

Dust

Density of dust and water droplets.

• 0 no dust

• 1 clear day atmosphere

• 5 city like atmosphere

• 10 hazy day

Ozone

Density of ozone molecules; useful to make the sky appear bluer.

• 0 no ozone

• 1 clear day atmosphere

• 2 city like atmosphere
