The Advanced Lighting rollout lets you select one of the advanced lighting options that accompany the default scanline renderer: either the Light Tracer or Radiosity.
The Light Tracer provides soft-edged shadows and color bleeding for brightly-lit scenes such as outdoor scenes. Radiosity provides physically accurate modeling of the light in a scene.
Until you choose an advanced lighting option, the Advanced Lighting panel displays a single rollout, Select Advanced Lighting.
Choose an advanced lighting option from this drop-down list. Default=No advanced lighting chosen.
When an advanced lighting option is chosen, use Active to toggle whether the advanced lighting is used when you render your scene. Default=On.
