In the few times I've tinkered with animating in Clip Studio Paint (outside of making small animations in Aseprite), I've been constructing "body parts" to puppet around to get my desired effect. One of my friends referred to this as "rigging" and I'm not really familiar with it myself. To any animators (or anyone in general) who is knowledgeable on the subject; What is rigging? What's the most friendly program for doing rigging? And where can I learn more about it outside of word of mouth?
