@taliatan So...kinda of a yes and no. The marshmellow pb DOES work but the scaling still does not. Yes i have turned off the former physbones and even tried making a preset but i just cannot seem to get the hang of it. Would you perhaps have time to walk me through this? Im a rather quick learner.
Yeah, looking at it now, lucky I've worked with enough Avis to get it how I want it to look hopefully i I don't want it to be Loona, but I just thought the base itself was really well made! I'll post a pic of mine when it's done
@Coral21 did you even put it into unity? when i downloaded it again, put it into unity. the fbx is within the unity package, its how the maker set it up..
