Position Sets a limit in units of how far the goal can be moved from the end
effector. Keep these numbers low.
Rotation Sets a limit in degrees of how far the goal can be rotated away from
the end effector rotation. Keep these numbers low for best results.
Note that adjusting the Rotation threshold on the HI Solver and IK Limb
Solver has no effect. It is up to the plug-in solver’s discretion as to whether or
not they will support a rotation component in the IK solution.
Solutions group
Use to control the precision of the animation. Increase the iterations when
the IK solution produces an animation that appears rough or jittered.
Iterations The number of attempts an IK solution will make to find the best
match between the goal and the end effector positions. Increase this number
if you are seeing jumpy animation.
IK Display Options Rollout (HI Solver)
Create a bone chain > Add an HI Solver. > Motion panel
Here are the controls to turn on and off a variety of gizmos in the viewport.
The Goal and End effectors, the vector handle of the swivel angle manipulator,
and the IK solver display itself, are all located in this rollout.
Procedures
To see multiple IK solvers in a single chain:
1 In a chain with multiple IK solvers, select a goal in the viewport.
2 In the IK Display Options rollout, turn on IK Solver Display Enabled.
3 Select a second goal and repeat the process.
Each goal's display remains on whether it is selected or not.
