>>191994You need HF Patch and BetterRepack for it. While in CharaStudio, there's a thing in the "Current State" tab in the "Anim" menu once you've selected a character that says "Show Bonemod" and you can just fuck around with scale values there. I also used the Pregnancy+ mod that comes with them since it lets you do fat stuff too. Once you start getting really big, stuff starts to clip so you gotta fiddle around a lot more for it to look right.
Sorry I completely forgot about this sequence. Procrastination is a bitch, and I kinda wanna redo parts of it now that I've gotten a bit better at using Koikatsu.
