Animate > Set Full Body IK Keys >
The Set Full Body IK Keys Options window lets you do the following:
Reach Mode
Specifies the Reach channel value of the selected FBIK effector and determines whether or not Reach is keyed when you click Apply.
Reach determines the amount of IK that is set for an effector. For example, a Reach of 1.0 determines that the effector is completely controlled by IK and a Reach of 0.0 disables the effector’s IK; allowing you to then animate the underlying FK skeleton’s joints.
When on, the Reach channel values of the selected FBIK effectors are set to 1 and are keyed when you click Apply. Also, the Reach channel values of all other effectors within the selected body part are set to 0 and the keys on the body part of the selected effectors are given Stepped Next tangents.
You can also set the Reach Mode to IK Key with the +3 hotkey or through the FBIK effector marking menu.
When on, the Reach channel values of the selected FBIK effectors are set to 0 and are keyed when you click apply. Also, the Reach channel values of all other effectors within the selected body part are set to 0 and the keys set on Reach are given regular Stepped tangents.
You can also set the Reach Mode to FK Key with the +1 hotkey or through the FBIK effector marking menu.
When on, the Reach channel values of your FBIK effectors are not changed or keyed when you click Apply. Simple key uses the global default tangency. Simple keys are most often used to rough out your character’s animation before keying the finer details of your FBIK animation with IK and FK keys.
You can also set the Reach mode to Simple Key with the +2 hotkey or through the FBIK effector marking menu.
