2d animation that runs is always on

Hi all,

I realize this is probably a really simple question, which is probably why I can’t seem to find the answer, but I have some simple 2d sprites like airplanes and helicopters with simple animation controllers (Idle, Up, Down) and I want a part of those animations to always be on, like the propeller. My trouble is that when I use another animation, like “Up”, the propeller stops spinning because I haven’t added propeller animation to my “Up” animation.

Can I create actions like up and down and have the propeller spin constantly without having to add the propeller spinning keyframes to every animation?

Nevermind. It was a mental block. All I had to do was ad an animator controller to the propeller component.
