The parts I used physics constraint can not be exported rightly , animation seems fine in Spine but gif exported is not right ,also at the export interface the first frame and the last frame where I used physics constraint are different although I copied first frame to last frame .Anyone knows how to deal with this problem? thanks! below are first and last frame
