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.

Options

Inverse Kinematics panel.

Target

Data ID used to select the an armature.

Pole Target

Object for pole rotation.

Iterations

Maximum number of solving iterations.

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

Position

For Tree-IK: Weight of position control for this target.

Rotation

Chain follow rotation of target.

Target

Disable for targetless IK.

Rotation

Chain follows rotation of target.
