iterations have not been performed.
• The last solution calculated is used if the
maximum number of iterations is reached,
regardless of whether the solution satisfies the
position and rotation thresholds.

Thresholds
You set the threshold and iterations settings as a
trade-off between accuracy and speed. You have
twogroupsofsettingssoyoucanindividuallytune
the behavior of applied IK and interactive IK.
• Use interactive IK if you want fast, real-time
response. Your interactive IK preferences
should be set for speed.
• Use applied IK if you want the solution to match
the follow objects very closely. Your Applied IK
preferences should be set for accuracy.
The default applied IK and interactive IK settings
are shown in the following table:

Interfa ce
Thresholds group
These sett ings are the same as those in Customize
menu > Preferences > Inv erse Kinematics. They
set the threshold for the changes in position and
rotation between the end effector and the last link
of the chain.
Posit ion—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 b etween 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
