Unity Package to Copy and Paste transform orientations using your clipboard
Unfortunately Unity's default serializer JsonUtility doesn't like to serailize deep hierarchies :( so it depends on Newtonsoft.JsonConvert
In unity, go to Window -> Package Manage -> Plus -> Add Package from Git URL and paste in:
https://github.com/hedgewizards/PoseClipboard.git
Attach Pose Clipboard component to the root of your armature. click "Copy Pose" to put the pose into your clipboard. click "Paste Pose" to apply the pose from your clipboard.
only the transform's LocalPosition, LocalScale, and LocalRotation are replicated, and it is dependent on the order.
