You can have another state in your state machine, that is for when your character is Idle or stationary, that just plays your Idle animation. Then you have your state for Walking/Running, and a transition that goes from Idle to Walk/Run when Speed > 0. Then also have a transition from Walk/Run to Idle when Speed = 0. You can check any of the Paragon characters’ animation blueprints from the Marketplace, they’re free, and you can get an idea of how they set it up. They are a bit more complicated than your system, but it can still be quite helpful!
