From “Outdoors” When on, casts shadows from objects outside the portal;
that is, on the side away from the arrow icon. This is off by default, because
turning it on can significantly increase render times.
Shadow Samples The overall quality of shadows cast by the portal. If the
rendered image is grainy, increase this value.
Advanced Parameters rollout
Visible to Renderer When on, the mr Sky Portal Object appears in the rendered
image. Turn this on to prevent outside objects from appearing in the window.
Transparency Filters the view outside the window. Changing this color doesn’t
change the light coming in, but has the effect of darkening outside objects,
which can help if they’re overexposed. To avoid recoloring the outside view,
use a shade of gray, such as R=G=B=0.5.
Color Source Sets the source of the light from which the mr Sky Portal derives
its illumination.
■ Use existing Skylight Uses the skylight. By default, with the mr Sky light
using the mr Physical Sky environment map at their default values, this
tends to give a bluish illumination, as with real-world skylight.
■ Use Scene Environment Uses the environment map for illumination
color. Use this if your sky light and environment map are different colors,
and you wish to use the latter for the interior illumination.
■ Custom Lets you use any map for the illumination coloring. Choose
Custom, and then click the button (“None”) to open the Material/Map
Browser. Choose a map and click OK.
