This signal is useful when linking different Nodes that should have equal hierarchical dependency to each other.

Here you will find the final values of all created variables after the loop has been processed according to the Inner Area settings. It is therefore always the last value that was sent to the respective Next output. In addition, you can also add your own outputs by right-clicking on the Node and selecting Add Output/Add New Output, which can then also be used to output values for each loop pass. Here is an example to explain this difference:

In this example, the values 0 to 10 are processed via an Area Node using loop transfer. As can be seen in the following illustration, only the value 1 is added to variable 1 within the loop transfer, which is then also linked to variable 1 at the output of the group for the next loop pass. In addition, however, an output named LoopingOutput has been added to the group (right-click on the group and select Add  Output/Add New Output ), which also receives the value of variable 1 increased by 1.

Both variables are used in the following circuit to stack cubes along the Y-axis. The red cube represents the result of the loop variable Variable 1. This means that only one value is output after the complete cycle of the loop.
The height of the green cubes is affected by the manually added Looping Output variable. There we receive a value after each run of the loop. As a result, 10 green cubes are stacked in the scene at the end of the calculation.

In summary, it can therefore be said that variables added via the Add Input button on the Loop Carried Value Node only ever provide a value at the end of the loop passes and outputs added manually via Add New Output can also provide values during the loop passes.
