Sets the chain effector's solution, rotation, and blending.
To display: Do any of the following:
Select any chain element and press Ctrl+R or choose Create Skeleton Inspect Chain Properties.
In the explorer, click the Kinematic Chain icon in a chain's hierarchy.
For more information, see Choosing How an IK Chain Reaches Its Goal [ Character Animation ].
Solver |
Selects the solver to use for the chain's IK. |
Solver Angles |
Sets the method of calculating joint rotations based on the preferred angle.
|
FK/IK Blend |
Sets the blend weight between inverse kinematics (translation of the effector) and forward kinematics (rotation of the joint) on the selected chain. A value of 0 is 100% FK, while 1 is 100% IK (but still using the rotation on the bones as a preferred angle state). For more information, see Blending Between FK and IK Animation [ Character Animation ]. |
FK/IK Ghosting |
Displays ghosts of the FK/IK values on chains when FK/IK Blend values are at 0 and 1. You must also activate Animation Ghosting and Skeleton FK/IK Ghosting in the view to see ghosting. You can set up the display on the Ghosting page in the Camera Display property editor. |
Force IK |
Triggers IK every time you modify the preferred angles from the Kinematic Joint property editor. This lets you immediately see the effect on the chain. For more information, see Forcing the Effector's Position [ Character Animation ]. |
Lets you lower the error tolerance for the solver when there are problems with the effector jumping or "popping." This is most likely to happen on 3D chains that have many bones or that have stiffness or rotation limits set for them. Lowering the threshold means that less distortion is allowed to occur as it solves the chain's angles.

If Affected By Last Bone is selected, you can also select either of these options:
