Indirect Lighting

Indirect Lighting refers to the feature of processing light reflected from mirrors and other surfaces.

Indirect lighting, or 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 performance cost. More passes will be required to resolve the image, and each pass will take longer.

  • More realistic lighting effects.
  • Subtle, soft shadows due to reflected lights.
  • Better images for presentations.

This Cove Lighting image is an extremem example

All light in the rendered image is first reflected from the ceiling, and then also
reflected from the floor, walls and other surfaces.
