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

Tingueu en compte que aquest tipus de cel és bastant brillant i fa que la imatge sembli sobreexposada amb la configuració d’escena predeterminada. Podeu reduir el paràmetre d’exposició a per solucionar-ho.
- 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. 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
- Pols
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
