For Dark legends we had a character customization system that allows you to choose any clothing item and switch between male and female while still wearing the same clothing. Usually a costume was designed for one sex and needed to be made available for the other.
Naturally we didn’t want to have to create male and female versions each from scratch. I created a tool to quickly create the opposite sex item. After running this tool there might occasionally need to be a few minor tweaks but this saved hours of tedious manual labor for the artists.
