It has breast joints. Might add more jiggle joints in the future, we’ll see.
As for people wanting more body morphs, I can add an arbitrary amount of body morphs and I probably will add more at some point in the future. Right now I’m focusing on getting the project up and running and adding a dozen morphs for the characters+all the clothing would take too much time so I’m settling for fat/skinny/muscular to start off with.
