How to enable animation of linked rigged object I made a simple stickman with joints. Works fine. Saved it as stickman.blend. I grouped CTRL+G the stickman+armature.

I made a new scene.blend file. I linked the group from the stickman with ctrl+alt+O into the scene. It is visible with all joints. So far so good. But I can not get it into Posemode. I think this is because it is "hard" linked to the stickman.blend. So I need a tip, how I can animate this in a new scene.

I don't want to simply append it to the scene, because when I make changes to the stickman they should also appear in my scene.

So for such a low level question. But after google/youtube I was out of an idea.

thanks for your help in advance
you have to use the Proxy Objects :

A proxy is a legal stand-in or substitute for the real thing. In Blender, when you make a linked copy (described above), you cannot edit the object; all you have is a link to it. You cannot add to it or change it, because its source is in another file that is not open.   Blender Manual


to convert the linked object into a Proxy Object you select the linked Object and hit Ctrl+Alt+P now you can animate the proxy object and it will get updated to the linked when you reload the file.
