Ok so I tweaked some stuff and I'm making some progress so I tought about posting some pics!
After reading lots of stuff online I managed to get rid of her old hair and I replaced it with the mkx one, I did this mostly because her mk9 model is kinda terrible and you can't even move her hair properly...
So basically now I can animate her hair as well, I'm not sure if it's going to break some things later on but so far so good.
Let me know what you think and if you have some suggestions!
