Issue description

scene\animation\animation_mixer.cpp:663 - AnimationMixer: 'anim/unarmed-swim-idle', couldn't resolve track: '%GeneralSkeleton:RightUpperLeg'. This warning can be disabled in Project Settings. (User)

To make this node reusable by multiple different model scenes, I made it a separate scene and set an empty skeleton and animationplayer with %naming, the animationplayer loads external animation lib so it can be used for animation tree node editing

However, this would trigger an error and it takes a long time to load every time.

Steps to reproduce

create A scene import the glb with animation player,and create a animationtree for it.then save the animation tree as a branch scene.

Minimal reproduction project (MRP)

1.open player/roles/male_warrior/MaleWarrior.tscn remove animationtree node reinstance a RoleAnimationTree scene on it .and see the error

2.open assets/models/male_warrior/male_warrior.glb select load pose to use external animlib and select assets/anim.res, see another error(can not pick bindbones animlib.Even man.glb and male_warrior.glb its the same bone map)

and because the old bug feature.different scene use the branch animationtree scene.the node on the animationtree will effect both.so I must set every node on the animation tree and the animation tree branch scene checked on the local to scene.that do a stupid work.every tscn contain the animation tree branch scene will has many node val on itself.

Could you provide a minimal reproduction project that triggers the issue right away? This would make debugging and fixing the issue much easier than having to try to manually reproduce what you describe.
