I am testing out the motion live plug in with the live face app for iphone X, but for some reason the expression mapping panel seems useless? When I open it i can adjust my characters face, allowing him a wholesome smile. As soon as I click preview or record however he goes back to having a mean old not smiley face. Trying to smile makes him look both evil and messed up. I am including a video so people can see. Any idea whats up?
