What is the difference between ik and fk

This made a potentially slow and painful process for our animator quick and easy. Every bow-wielding character in Wulverblade uses this set up. Inverse kinematics are an extremely useful tool and always fun to experiment with. Combined with other newer features, like Skinned Mesh which will be our next topic here on the Wulverblog , we are able to get some really fantastic, expressive movement out of our characters.
