I thought posing in maya would be a straight forward process but oh how wrong i was. I struggled so much with the key-frames and i couldn't for the life of me figure out what the issue was. I would set a pose and then move to the next on a different frame and the initial pose would become totally messed up. I had this same problem with most of my first attempts and i still don't really know why. My best guess is that i didn't key frame the first pose correctly and that what caused the problem. 2nd attempt but as you can see he spins around for reason This is a much better attempt but the shoulders decide to do an odd rotation.
