It seems to be all of my models. I did a bit more testing and it only seems to be the hand gestures in the motion override section. The only gesture in the motion override section that is not affected seems to be the "hold" gesture.
Im having an issue in both of the new 1.5 versions where the thumbs on all of my models is not in the position its supposed to be. ex : the thumb will be on the back of the hand or on the complete other side of where its supposed to be. It doesnt happen on the built in model, but I've never had it happen to any of my models in the app's older builds and they don't do it in pmx editor. Just wanted to let you guys know so you can fix it .
