Shared Pose Library

Is it possible to create a pose library that is shared between multiple .blend files? Basically so if I create a pose for one character model’s file, all other character models automatically gain that pose in their pose libraries.

Again, this question needs to be asked in the other animation thread. This is for animations and animations in progress. To answer your question, as long as the same rig is being used, you can use it for multiple models.
