You could use a single database containing all of your clips if that’s the approach that you really wanted to go for. However, you’ll very likely run into more issues with pose selection if you go down that route, so, at the least, you would need a more complex schema with that approach. We recommend using multiple databases because it simplifies the dataset that the system is matching against to animations that are contextually relevant for whatever state the character is in (ie. locomotion vs idle).
