IK Solver Constraint

The Inverse Kinematics constraint implements the inverse kinematics armature posing technique. Hence, it is only available for bones. To quickly create an IK constraint with a target, select a bone in pose mode, and press Shift-I.

This constraint is fully documented in the Inverse Kinematics page, part of the rigging chapter.

Target
Data ID used to select the an armature.
Pole Target

Chain Length

How many bones are included in the IK effect. Set to 0 to include all bones.

Use Tail
Include bone’s tail as last element in chain.
Stretch
Enable IK stretching.
Weight

For Tree-IK: Weight of position control for this target.
Rotation
Chain follow rotation of target.
Target
Disable for targetless IK.
Rotation
