Nó Textura de céu¶
The Sky Texture node generates a procedural sky. It’s typically used in combination with the World Output Node.
Inputs¶
- Vector
Coordenada de textura para amostrar a textura em; padrão para coordenadas de textura Geradas se o soquete é deixado desconectado.
Propriedades¶
- Tipo de céu
Modelo de céu para usar
- Preetham
Based on the 1999 paper by Preetham et al.
- Hosek/Wilkie
Based on the 2012 paper by Hosek and Wilkie.
- Nishita
Improved version of the 1993 model by Nishita et al.
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 to fix this.
- Direção do Sol
Vetor de direção do sol
- Turbidez
Turbidez atmosférica.
2: Arctic like
3: céu limpo
6: dia quente/úmido
10: dia nublado
- Albedo para base
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
