# Ep.16 — Controllers Node Reference (`Ctrl_*`)

This document shares the naming guidelines for `Ctrl_*` controller nodes generated by BipedPlus as default values.
It reflects the controller naming conventions OtakuSolutions follows for 3dsMax rigging.

If your team does not have internal rigging naming guidelines, feel free to use this document as a reference.
When customizing the rig, maintaining these node names ensures full compatibility with BipedPlus.
