I'm trying to animate using keyframes for a my 3d animation class. I've set the first frame and the last frame just fine, but when I go set a keyframe in between, the pose doesn't stick. I've keyed everything I did when setting the other two poses, but as soon as I move anywhere on the timeline, maya ignores the fact that I ever set that pose in the first place. the animation runs exactly as it had before I put the key in between the first two (with the exception of the lattice deformations I made, actually).
I've tried this twice now and it hasn't worked either time, plus it's also just really frustrating because there's no way to get back all the work I did posing my character. Help?
