Wow, thank you so much for taking the time to explain this to me., the way it works is even more impressive than what I had imagined. This is my favorite plugin among your collection, and I would even say among all MZ plugins I know of. Even more than that, it was a major contributor in giving me the motivation to start my project. Character creators are the one feature I look for in the types of games I play, so I couldn't imagine making my own game without one.
So thank you for making this, it really means a lot to me!
I do have a question about the possibility of adding a certain feature. I don't know if DairyFreeLemon's idea would allow me to do that, but I was wondering if it would be possible to work with different poses (the basic walking / idle / running but also custom poses such as sitting / dancing / etc.). For example, you could have different folders for poses and the generator would "match" the chosen parts with their counterparts that have the same filename in each folder to create multiple spritesheets.
Unfortunately, my game includes multiple poses and I think that could be the case for similar games that would want to include character creators. I know the plugin doesn't support that right now, but is this something that could possibly be done in an eventual update (in a faraway future of course)? I would even be willing to commission you for this feature, because I know the HUGE value of the work and effort you put into your plugins :)
