Parent Constraint's break joint movement

[glen_kre0001]

I'm having a problem where my rig breaks at the neck joints and every other joint in the head. this seems to be happing when I use parent constraints on the next joint above the previous constrained joint. The root joint doesn't move the children joints with it but instead just rotates in place when rotating the nurb control.

Hi!

Since you are going for an FK setup with your head and neck, the hierarchy of your controls should mirror the hierarchy of your joints. So parent them under each other and then constrain them like this:

Then you put your Neck control Buffer under your Chest Control:

And put your joints into a Head and Neck Buffer Group and put them unter your Skeleton Group:

 

This way Masters and Slaves are in the same spaces an should behave as expected with the rest of the rig.

I hope it helps!
