I went through P2Design’s rigging course and it does a fantastic job. If you want to get into rigging it takes a lot of the confusion out of it when you’re starting out. I haven’t taken any of the iAnimate rigging classes but kind of want to. It would be cool to know the process for both programs. I’m having a lot of fun rigging a character I had commissioned. Its getting REALLY close to time for animation tests.
