This is my biggest trick for creating characters with Anime Studio Pro.
In this Anime Studio tutorial, I'll cover how to rig a character in Anime Studio Pro so that you can reuse your animation and get many cartoon characters out of just one.
There's no point in having to animate each and every cartoon character you create. That's too much work. Instead, create one skeleton and animate it in every way possible, saving each of the animations as actions. Then, build every cartoon character you can on the same skeleton. I use multiple pieces for each body part to make a master character, then I delete the pieces I don't want and save the new character. The best part, he's already rigged with actions that can be animated in my next cartoon!
