if classof theNode.modifiers[n] == turbosmooth do result = true
)
)

local allSelectedGeo = for curNode in $selection as array where superclassof curNode == Geometryclass and not hasTurboSmooth curNode collect curNode
addmodifier allSelectedGeo (TurboSmooth iteration:2 sepBySmGroups:true)
addmodifier allSelectedGeo (TurboSmooth iteration:1)
)
