谢谢你寄来的复制包。
Thanks for sending the reproduction package.
由于你没有设置任何皮肤（Initial Skin Name留在default），你需要在sg.Initial Initialize(true);之后调用sg.Skeleton.SetSlotsToSetupPose();。
Since you are not setting any skin (Initial Skin Name is left at default), you need to call sg.Skeleton.SetSlotsToSetupPose(); after sg.Initialize(true);.
sg = obj.GetComponent<SkeletonGraphic>();
sg.Initialize(true);
sg.Skeleton.SetSlotsToSetupPose();
sg.AnimationState.SetAnimation(0, "anim2", true);
