What I'm asking is basically to do in Neo Studio 2 what the HS2 game itself does - have a male char and use the same positions for different female chars.
I know I will very likely have to do adjustments of course, but are there ways or tools to make replacing the female (or male) char in an existing animation easier?
For changing female char to another female char, first click on the char you want to change in the Workspace box (on the right), then on the left of the screen, click on the Add > Girls > select which female char you want, and click the "Change Character". This "Change Character" button is only enabled if the characters are of the same gender.
For changing male to female char, this is more complicated, because as mentioned above, the "Change Character" button is disabled for different genders, which seems to be a StudioNeo limitation.
I do not know if there is a more efficient method to change a characters' gender (maybe with another mod, or VNGE) but I have asked before in this forum and was told there wasn't any other ways, so if you do know another way, please share too.
