Multiple Animations, Multiple Scenes?

Hi,

I am new to animation and I am trying to animate a spaceship. My goal is to export the model/animations for use in a game I am developing with Unity. I have added multiple actions like FlyForward, FlyForwardTurnLeft, etc. My model is following a path in each action. However, each animation seems to get corrupted when I change the curve of the path. Do I need to animate each action in its own scene?

Regards
