NodeCounting Loop Start

LoopStart

The LoopStart is the node that starts a loop that is executed a predefined number of times. At the end of the loop you need LoopEnd, which collects the results from all loop iterations. All nodes in between are executed as many times as you specify in the dialog of LoopStart.
