Adding Indirect Lighting to an Exterior Rendering - using the effect of lighting reflected from other surfaces - can add some subtlety and realism to your exterior rendering. In particular, the undersides of overhanging features such as eaves or balconies can be rendered more accurately when using indirect lighting.

This subtlety, however, comes at a substantial performance cost. More passes will be required to resolve the image, and each pass will take longer.

Use the following steps to enable indirect lighting for your exterior rendering:

1. On the Lighting tab, select the Exterior preset.
2. Check Show Advanced Tab.
3. On the Advanced Tab, change Indirect from Off to Exterior.
