Sky Texture Node.

The Sky Texture node adds a procedural Sky texture.

Đầu Vào -- Inputs

Vectơ -- Vector

Tọa độ chất liệu để lấy mẫu vật chất liệu tại đó; Trong trường hợp ổ cắm không có kết nối nào thì sử dụng tọa độ của chất liệu sinh tạo (Generated).

Tính Chất -- Properties

Loại Bầu Trời -- Sky Type

Sky model to use.

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.

Hướng Mặt Trời -- Sun Direction

Sun direction vector.

Độ Vẩn Đục -- Turbidity

Atmospheric turbidity.

  • 2: Arctic like

  • 3: clear sky

  • 6: warm/moist day

  • 10: hazy day

Công Suất Phản Xạ của Mặt Đất -- Ground Albedo

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

Sun Disc

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 in kilometers from sea level to the location of the camera. For example, if the camera is placed on a beach a value of 0 should be used. However, if the camera is in the cockpit of a flying airplane 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
