What is the best way to run an animation on a character alongside its animation tree?

Question

So my 3d character animations are controlled by an animation tree state machine, and I’d like to add another animation that should always play simultaneously with the current animation tree state. For example, a flying helicopter’s rotor keeps spinning no matter what’s happening to its other parts. What are the best ways to do it? Put the entire tree and that other animation into a blendspace?

If it’s part of the same armature/skeleton3d then you will have to blend or add the animation in a blend tree.

If it’s not part of the same armature/skeleton3d then you could add another AnimationPlayer too loop the seperate object.
