Yeah I know there is one, but its kinda of crappy. It doesn’t let you edit the hands or face at all.
It’s an anime model what did you expect? Not many of them are given those. My only problem with the FMA models is that they are too big compared to other models. Be grateful you even got them in the first place.
This is a request topic, so I have the right to request, and I have a lot of anime models with moveable finger joints, that usually isn’t a problem. The person who made the first one pretty much said he wasn’t putting a lot of effort into it.
There’s a lot of limitations with what you can do with it so it’s no wonder.
