Where to find free animations for a roblox game?

The gotcha first: an animation only plays in your game if it's owned by you or the group that owns the game. So dropping a random animation id from the creator store into a script often does nothing in a live server, even though it previewed fine in studio. If the creator allows it, open it in the animation editor and publish your own copy. For sources, the creator store has a decent pile if you filter to animations. The built-in animation editor is fine for simple stuff like waves and idles, and the animation capture option that works off your webcam is surprisingly good for emotes.
