I have a script that automatically generates animation clips from spritesheets. I want to create a GameObject add the created clips to it and save it as a prefab. All this should happen in the script, no manual work. This works only as long as clip name and AnimationState name are the same e.g.:

string animName = "walk";
string clipname = animName + ".anim";
animation.AddClip(clip, animName);

will work. But I if I do this:

string animName = "walk";
string clipname = "Berserker - " + animName + ".anim";
animation.AddClip(clip, animName);

It will add the correct animation states to Animation, but when I save it as prefab (or press apply, doesn't matter) the prefab will show an empty animations list. Is this a bug, or is there an explanation why this can't work?
