You can connect a reference object directly to this port. This saves you from having to manually enter the path in the Reference Path box.
Suppose you want the node to output ten objects only, even though there are more than ten objects that can be found by the Iteration Path. Here you can set the maximum number of iterations.
The On input port takes a Boole value that enables (True) or disables (False) the node. The node is enabled automatically if you do not add this port.
The following output ports are available:
The objects found.
The total number of objects in the hierarchy being searched. In other words, this is the maximum number of objects that the node would be able to find via the Iteration Path.
