The default name for the attribute is
Each primitive or point is assigned a number from 0 to the number of connected sets minus 1. Two primitives or points that share the same number will be connected.
Determines whether it is to be points that are classified or primitives. The attribute will be a point or primitive attribute depending on this setting.
The name of the attribute to create.
The name of the local variable to map the new class to. By default it is the ALL CAPS version of the attribute.
Available only in the Primitive Connectivity mode.
A group of edges that are treated as additional topological boundaries when determining primitive connectivity.
Use UV Connectivity
Available only in the Primitive Connectivity mode, and when no Seam Group is provided.
Normally, two primitives are considered connected if they share any points. If this is set, they are instead considered connected if they have vertices that have the same vertex texture cooridinate.
Note that this applies to vertex texture attribute, not point texture attributes.
