Procedure
ToseemultipleIKsolversinasinglechain:
1.
In a chain with multiple IK solvers, select a goal
in the viewport.
2. IntheIKDisplayOptionsrollout,turnonIK

3. Select a second goal and repeat the process.
Each goal’s display remains on whether it is
selected or not.

bone in the chain. > Open the Hierarchy panel. > IK
button
Here are the controls for setting the joint limits
when using the HI Solver. You can turn X, Y, or Z
axes on or off, limit them, and set those limits here.
This is also where the preferred angle is defined,
and adjusted. The preferred angle defines the
