To define new sun and shadow settings for the rendered image, select Edit/New. See Defining
the Sunlight Source for Shadows on page 204. Click OK or Cancel to return to the Rendering
dialog.
3 If you selected a lighting scheme that uses artificial light, click Artificial Lights to control artificial
light in the rendered image.
You can create light groups and add lighting fixtures to light groups. You can also dim or turn
on or off light groups or individual lighting fixtures. See
Light Groups on page 1134. Click OK or
Cancel to return to the Rendering dialog.
TIP To improve render performance, turn off any lights that are not required for the rendering. See
Turning Lights On and Off on page 1139 and Render Performance and Lighting on page 1173.
4 If the lighting scheme is Interior: Sun only or Interior: Sun + Artificial, consider whether you
want to turn on daylight portals.
During the rendering process, daylighting is performed automatically. For advanced lighting
quality in interior views, you can enable daylight portals, if needed. Daylight portals improve
the quality of the rendered image, but they can also increase render time. By default, daylight
portals are turned off. See
Daylight Portals on page 1165.
