Free update V1.2: 30/11/20 for existing users

This Zbrush plug-in is based on the tutorial I wrote last year. It's designed to give you more controllable loops in Zbrush. It also has a few other functions like clean extraction and retopology from masking and slicing. It's by no means a replacement for manual retopology but it will get you part of the way there and can even get you some quick clean game res models out.
*This tool only works for Zbrush 2019 and above*
