OD Target Children Takes an Item, and targets its children to the next child:

Options:

• Loop: Defines whether the last item gets targeted back to the first item.
• Add End: When using splines, its beneficial to add an end item if you are not doing a loop. That end item can then be offset so that the last “kink/flip” is outside of the use range.

Target Children is very beneficial when setting up spline control animations. It allows you to quickly and painlessly get rid of any kinks/flips in your curve
