7.02 Sky Dome

Create a consistent color or gradient dome for lighting your scene.

F.01 Sky Dome options

• Intensity (cd/m2): Type in the intensity of the Sky Dome in cd/m2. It is a common

way to specify how much light is emitted.

• Zenith: Specify the color of the dome at the zenith (the highest point above our

head)

• Horizon: Specify the color of the dome at the horizon.

• Mid Point (degrees): Specify the transition between the Zenith and Horizon

colors. This value indicates the angle at which the contribution of the colors

is equal, where 0º and 90º correspond to Horizon and Zenith respectively.

If you want a consistent color for your dome, simply choose the same color for both

Zenith and Horizon slots. You can drag and drop colors from one color slot to the

other, to copy the same exact color.

• Sun: When checked, Sky Dome will render together with the sun from the current

Physical Sky settings. You can rst adjust the sun by switching to the Physical Sky

environment lighting and adjusting the location/ time/ date, and then switching back

to Sky Dome.

7.03 Physical Sky

Maxwell Render™ has a sophisticated atmosphere model that reproduces the skylight

conditions at different locations/ times/ dates. The atmosphere parameters allow users to

customize the look of the sky and the resulting light in the scene. Users can also create

pre-sets of the sky settings to quickly load a new sky or share their pre-sets with other

users, or save a sky as an HDR/ EXR map.

• Load:

• From Disk: Allows you to choose a location to load a .sky pre-sets le.

• From Google Earth File: Allows you to choose a location by loading a Google

Eath location le in .kml or .kmz formats.

• Preset: The dropdown will list all the saved pre-sets found in the Maxwell/ skies

folder.

• Save:

• As Preset: Saves a .sky preset le in the Maxwell/ skies folder.

• As HDR: First specify a location for the HDR le, then a resolution. The default

format is a longitudinal HDR map (2:1 width to height ratio).
