So I created a character, rigged it using rigify and created a simple walk action. Next I linked it to my scene blender file and created a proxy to work on it. In the scene, I saw the walk action and I added it to the NLA strip. Now, when I try to do anything else, like make him stand, bend, it replaces the walk strip. I tried changing the blend mode to add, but that completely messes up the mesh. How do i go about adding more actions to a linked character with an action of its own.
