Multiplier A scalar multiplier for the light output. Default=1.0.
Ground Color The color of the virtual ground plane. Note that this is a diffuse
reflectance value (that is, albedo). The ground appears as a Lambertian reflector
with this diffuse color, lit by the sun and sky only, and does not receive any
shadows.
TIP Some sky models neglect the influence of bounce light from the ground,
assuming only the sky is illuminating the scene. To compare the output of mr Sky
with, for example, the IES Sky model, set Ground Color to black.
Sky Model Lets you choose the sky model to use. There are three
choices:
■
Haze Driven on page 5179
■ Perez All Weather on page 5179
■ CIE on page 5180
Use the Perez or CIE model when you want light from the sky to be physically
accurate.
