HumanIK Animation problem in maya.
I am a novice animator and modeler. I have been learning how to work with Maya 2013 myself through youtube tutorials and Google. I am stuck with the HumanIK tool while trying to animate my model. I have a Biped model that is rigged and weighted properly. I just started messing around with the HumanIK because of the built in control curves it places on the skeleton.
The problem I am having is with the keyframes. I can’t really think of a way to explain it in question form so I’ll just give an explanation of what is happening. I have a 24 frame test animation. On frame 1 and 24 I have the model standing. On frame 12 I have the model translate down on the y axis a bit, so it will return to the starting position on frame 24. I then add something simple such as moving the arm to the side on frame 18. The problem is that the arm doesn't start moving on frame 1 - 18 – 24, it starts on frame 12 - 18 - 24. It seems on the timeline that when I set a keyframe the whole rig gets set instead of the control I have selected. This problem is really messing me up when I am trying to animate something more complex.
Any ideas on how to fix this problem?
