Adjusting IK Blends

The HumanIK Controls sliders in the Controls tab let you adjust the amount of influence each solution (IK or FK) has on a particular body part. This gives you complete control over which solution your skeleton follows between the synchronized keyframes.

Use the following guidelines when adjusting IK Blends:

• At 100%, the skeleton follows the IK solution.
• At 50%, the skeleton averages between the IK and FK solutions.
• At 0%, the skeleton follows the FK solution.

To adjust the influence each solution has on your skeleton

1. Select an effector in the Character representation.
2. Adjust the percentage of translation and rotation between the IK and FK solutions using the IK Blend T and IK Blend R sliders.

   The cells of the Character representation update to give you visual feedback on IK Blend settings. (See IK cell status.)

For example, a value of 30% is assigned to IK Blend T in the image below. When the character's wrist effector is translated, the skeleton reaches towards the FK rig because it is following the FK solution more closely than the IK solution.
