Вузол «Текстура Неба» – Sky Texture Node

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.

Властивості

Тип Неба – Sky Type

Модель неба для використання.

Single Scattering

Improved version of the 1993 model by Nishita et al, accounts for single bounces in the atmosphere. This is legacy and may be removed in a future version.

Багато Розсіювання – Multiple Scattering

Based on this work by Fernando García Liñán, it is the most accurate model as it accounts for multiple bounces of light in the atmosphere.

Preetham

Based on the 1999 paper by Preetham et al. This is legacy and will be removed in a future version.

Hosek/Wilkie

Based on the 2012 paper by Hosek and Wilkie. This is legacy and will be removed in a future version.

Примітка

Single and Multiple Scattering skies are very bright by default (hence accurate). You can lower the Exposure of the scene in Properties ‣ Color Management ‣ Exposure to fix this.

Sun Direction

Sun direction vector.

Turbidity

Atmospheric turbidity.

• 2: Arctic like

• 3: clear sky

• 6: warm/moist day

• 10: hazy day

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.

Air

Density of air molecules. A value of 1 corresponds roughly to urban city air, while 0 is no air.

Aerosols

Density of aerosol particles (water droplets). A value of 1 corresponds roughly to urban city aerosols, while 0 is no aerosols.

Ozone

Density of ozone molecules; useful to make the sky appear bluer. A value of 1 corresponds roughly to urban city ozone, while 0 is no ozone.
