Num Samples

This option generates fixed samples at each shaded point. More samples may help resolve noise in fewer camera samples, but may reduce performance at higher numbers.

Sample Distribution

Different samples distributions can be used to create different occlusion effects.

Max Distance

As each point is shaded, rays reach into the scene to strike nearby objects. In some cases, like an interior, this may produce a dark or black result. You can reduce that distance using this control. Note this is measured in scene units. The default is 0 or infinite.
