Hello all, I was wondering what was the pros and cons of full body IK that used in Kinefx. The general rule is that the legs and arms of a model would have ik but what's the difference with fullbody. I tried googling to see what were the benefits of full body IK and got absolutely nothing. Any rigger or animator knows of the benefits of it? Or is it just a buzz word and I should set up IK like I would with regular IK?

It all depends what are you using it for, other than just for classical keyframe character animation. If you are retargeting or using some ways in experiment with joints with other sop tools it can be good in achieving believable body movements, which you would never be able to achieve by simply using IK chains. There are few steps necessary to configure it right, but once you make it work, it does miracles, definitely recommending experimenting with it.
