So I used to animate with the software called ‘anime studio’ and it had a feature called “switch layers”. Basically with switch layers you could put multiple objects in a group, and toggle between them so that you could do things like lip sync, eyelid animation, etc. Heres an example https://youtu.be/pUYHStd8A-Y?t=3m59s If anyone knows a way of doing this, PLEASE tell me asap!
Use layers. Below is a link to the manual.
