automatically creates a group of vertices and allows you to assign each vertex weight in many different ways
vertIND - Connect here a list of needed vertex indexes, or node automatically creates a list of indexes of all vertices of the object
weights - vertex weights (floats less than 0.0 count as 0.0, bigger than 1.0 count as 1.0)
clear unused - (on side panel) zero weights for all vertices which is not indexed in the list of indexes
object name - name of object to create vertex group for.
