I was always planning on doing it myself, just gonna need some help. Not sure if it's normal, which I think it is, and idk how relevant it is, but apparently this is already rigged to a skeleton with an armature unless that's the same thing, and there's already vertex groups here. Not sure if that's what stays in segments when I move the skeleton to move the mesh I think it is. There might be a better way cause idk how to handle this kind of thing, but if everything is already segmented like this, is there a way to be able to take those parts separately and assign it to parts of a different skeleton or something for jka? I heard there might be something about bones, idk if that would get in the way of that. The mesh is all combined together and stuff it seems cause when I select it, it selects the whole thing, so idk how to maybe separate things and maybe port it over somehow and fix up another skeleton, unless this is just a harder way of doing things. I'm probably way off on what I'd actually need to do but idk if this helps me out somehow lol.
