FName RootBone
Remarks
All bones above this bone in the hierarchy will be completely ignored by the solver. Typically this is set to the top-most skinned bone in the Skeletal Mesh (ie Pelvis, Hips etc), NOT the actual root of the entire skeleton.
If you want to use the solver on a single chain of bones, and NOT translate the chain, ensure that "PinRoot" is checked on to disable the root from translating to reach the effector goals.
