Interface
Thresholds group
These settings are the same as those in Customize menu > Preferences > Inverse
Kinematics. They set the threshold for the changes in position and rotation
between the end effector and the last link of the chain.
Position Specifies, in units, the "slop" factor between the end effector and its
associate object. This is the allowable distance between the end effector and
its object, given the current IK solution.
Rotation Specifies the allowable number of degrees of rotational error between
a rotational end effector and its associate object.
Solution group
Iterations Specifies the maximum number of iterations allowed to solve the
IK solution. The actual number of iterations used depends on the difficulty
of the problem. This value simply puts a cap on it.
Start Time and End Time Species the range of frames in which IK is solved.
If the Start Time is set to 20 and the End Time is set to 80 in a 100-frame
animation, and then the end effector is animated, the animation of the chain
will only be correctly solved within the Start and End range.
