I want to drive an eyelid by a bone.
Wel i have normal eye setup, they are parented by a head-bone, by rotation and fixed offset location.
The eyes are simple spheres. who folow a typical blender eye bone setup.
The Eye lid is a half sphere, its slightly larger, so when the eyelid turns on its X axis it closes, the eyelid is only fixed by a location relative of the head-bone.
So on the eyelid object i went the objects rotation properties, put in a specific driver (only for x axis).
Then besides that head i created a new “face-view” bone parented it to the headbone with fixed offset.
Then I created 2 eye-lid-control bones besides the face-view bone to control each eyelid.
those eyelidcontrol bones are parented to the face-view bone, the faceview is a place holder for all face manipulations bones.
Then i selected one eyelid object (with the x axis driver), and went to its driver setup and made it as below
I was thinking this would work in pose mode moving my eyelid bone would change the values
but it doesnt, moving the bone doesnt rotate the half sphere ??
