CloneNodes

[Anonymous]

Hello！

I want to clone a node and use the function CloneNodes, but the max always prompt that there is a unknown system abnormalities. 

How to set the params of that function? Who can give me an example?

Read the Maxscript Help for MaxOps.cloneNodes very carefully. Many of the parameters are In or Out - references (pointers to arrays).
Create one or more objects and select it/them.

(
OldNodesArray = selection as array
ActualNodeArray = #()
NewNodesArray = #()

MaxOps.CloneNodes &OldNodesArray \
                  Offset:[20,0,0] \
                  expandHierarchy:true \
                  cloneType:#reference \
                  actualNodeList:&ActualNodeArray \
                  newNodes:&NewNodesArray
)
