Finally! I've got Flash CS4!
People in Adobe finally came to their senses and added inverse kinematics in Flash. I can't imagine how Flash animators managed to live without it, but one thing is for sure: I won't have to purchase Animer Studio after all. Yay Flash!
Anyway, here's my first animation test using Flash IK armature. It took me some time to get the hang of it (my mom was ticked off because I didn't leave the computer yesterday), but I finally did it.
