SSS Set Name - Arnold User Guide

It is possible to tag multiple objects as belonging to the same SSS 'set' so that illumination will blur across object boundaries. A common use-case might be blurring between teeth and gum geometry. It is enabled by adding the constant STRING userdata sss_setname to the same value on the objects in the set.

No sss_setname used (default)	Same sss_setname used across all objects
