...
A relative importance multiplier for this system in the global light transport step.
The default value is 1.0. Higher values should only be used for area light geometry in its own dedicated system (which is known to be a bright source of illumination at precompute time). Setting a high importance will ensure that the area light geometry is retained during the light transport compression step. If you use a high importance multiplier, you should also ensure that area lights have as few clusters as possible.

Threshold controlling input (duster) sample culling behaviour.
If the visibility of the sample is less than this threshold the sample is culled. Visibility is defined as the fraction of visible front-faces over the number of samples used for visibility (NSBudget). A value of 0, turns off sample culling. A value of 1 rejects the sample if any back-face is visible.

Threshold controlling visibility-based cluster triangle culling behaviour.
If the visibility of the triangle is less than this threshold the triangle is rejected and not part of the clustering; thus it will get no input samples. Visibility is defined as the fraction of visible front-faces over the hemisphere of the cluster. A value of 0 turns off visibility-based cluster triangle culling. A value of 1 rejects the cluster triangle if any back-face is visible.
