Flexi plane. Rotation. Expression.


#1

Good day to everybody.! I’m following along the tutorial about the advanced character rigging using flexi plane. Basically, I installed the plane into torso and neck. And here where the problem pops up:

I set the dynamic parenting to head, so it may follow or not follow the chest.
When it’s set to OFF and you rotate the TORSO, the TOP PART of the NECK flexi plane rotates as well, but it needs to be still.
The tutor shows a complicated (for dummy me) solution using Node editor, while I’m more into expressions.
So there is the problem: I’ve tried several ways but still cannot find a solution using the expressions method.

Peace.
