It’s not an if, Everyone who uses Apple ARKIT/Facial animation blendshapes is using at least 50 curves.
You can’t copy that curve data from one animation to the other.
I can copy translation and rotation curves for animations from one to another, but it seems as the BlendShapes curves aren’t possible. Unless of course i’m missing something.
Rather than just telling me i’m doing it wrong, if you have input on how to do it or what steps to take, i’m all ears.
