I drew the keyframes first, making sure the onion skin option was turned on, and then threw in keyframes randomly where I thought it was needed. Usually working between two already existing cells. This might be why I have some wildly inconsistent cell names.
If you have any good resources for learning how to animate, please share in the comments! Have you used the animation tool for Clip Studio? What did you think of it?
