入力

Vector(ベクトル)

Texture coordinate to sample texture at; defaults to Generated texture coordinates if the socket is left unconnected.

Properties(プロパティ)

Sky Type (大気タイプ)

使用する大気モデル。

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.

Sun Direction (太陽の方向)

太陽の方向のベクトル

Turbidity (濁度)

大気の濁り度。

  • 2: Arctic like

  • 3: 晴天

  • 6: 暖かい/湿った 日

  • 10: かすんでいる日

Ground Albedo (地面のアルベド)

惑星の表面から大気に反射される光の量。

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

出力

Color(カラー)

Texture color output.
