Mathaeus do you have any videos with practical use of this full body ik?
I saw thishttp://www.youtube.com/watch?v=abyVBv7k2cw
I'm not animator, but this doesnt make sense, he moves arm and head flips automatically?
ikinema website is spammed with motion-capture rework keyword, is it only for motion capture or what?
origin I thought you did a commercial some times back, didn't you animate then?
The influence In the video could be solved by pinning one of the joint.
An usage for FBIK would be let's say you wanted a characters arm to reach for an object on. With FK, you would first position the shoulder joint, then the elbow and finally the wrist. IK works in reverse and is far more intuitive, simply grab the hand and bring to the object and the wrist, the elbow and shoulder joints adjust automatically,
maintaining their proper orientation toward the goal, in this case, the hand.
(taken from the help file)
Although I doubt anyone would want to animate only in IK.
Hope it helps.
