Hi! RotAux is an auxiliary Layer, it stores pre-calculated rotated images (the image which walks the path). If you want to modify the PATH and re-animate with the same image layers, RotAux layer can be re-used, and execution time is optimised (because some angles were calculated and located in RotAux). In summary: RotAux is used to optimise execution time, can be deleted if you want. I hope this helps, and thanks for your question.
