Hey all im just at home sculpting away and i realise i have my model set up incorrectly thus causing the mirror line to be in the location when i press X, Zbrush is mirroring my model front to back rather than left to right, i know there has to be a way of changing the mirror lines pivot i just dont know how to do so or how to search that exact issue up on google! PLEASE HELP I AM SO STUCK!!!
look in the transform menu
