Transfer IK/FK for FINGER/TONGUE and stretchinesse for IK fingers.

[bouich jules]

Hello,

As i transfer and use only the FK rig in my game engine, i always transfer my animation when done to FK rig.

Today i decided to give a try to the figner and tongue in IK mode, but i noticed that the IK animation is not transfered to the FK like the rest of the bones.

‌

also is it normal that there is no stretchinesse control for the IK ring ?
