AnimationTree resets mesh scale and material properties to zero

Hi,

I’m using Godot 4.7 stable.

I have an AnimationTree with a BlendTree. My Idle animation does not animate the mesh scale or material. My Hurt animation animates the mesh scale and the material albedo.

As soon as I connect the Idle animation to the Output node, the mesh scale and the material properties animated by Hurt immediately become zero, even though Hurt is not playing.

I already checked that Idle doesn’t contain any scale tracks.

Is this expected behavior or is it a bug?

Thanks!
