Physical Sky Parameters

When Physical Sky is chosen as the Environment Type, the scene will be lit by an all-encompassing dome of light generated by Maxwell

to simulate the appearance of a natural sky. How this sky appears is controlled by a set of parameters divided into three basic groups:

 Sun Parameters: control the power and color of the Sun and the basic reflectivity of the planet

 Gas Parameters: control the amount of ozone and water vapor in the air

 Aerosol Parameters: control the characteristics and concentration of particulates in the air

Physical Sky parameters may also be loaded or saved using Maxwell .sky files, just click the ‘Load’ or ‘Save’ buttons. Note, .sky files hold

more than just atmospheric data; they include the date, time, location, and whether or not the Sun is enabled.

Sun temperature: Temperature of the sun’s spectral radiation. The default value of 5777 is the most common value

measured outside the Earth’s atmosphere.

Sun power: A multiplier that controls the amount of light emitted from the sun. Higher values than the default 1.0

will make the sun emit more light, lower values will emit less.

Planet reflectance: Controls the percentage of light reflected from the planet surface back into the atmosphere.

Turbidity Coefficient: Defines the concentration and amount of particles in the atmosphere. A value of 0.0 means a perfectly

clear sky (in which case the next three parameters won’t have any effect). 0.01 is a good value for low

turbidity, e.g. a sky containing very few aerosols, which will appear almost clear. 0.040 is a good medium

value and 0.3 is a fairly high value.
