Two bone knee in Motionbuilder?

Rigging
1

Is it possible to make the HIK rig in mobu properly
work with a skeleton which has two joints in the knee
for better bending?

The total bending of the knee should be distributed
between the two joints 50%-50% so the ankle ends
up where it should.

I tried constraints but I was not able to modify the
bone which is referenced in the characterization, so I
couldn’t half it’s local rotation.

no, just layer it on top if your going to do the two bone rig.
