I don't know why the length limit of the title is so strict..
I am learning face rig and trying to "suck joints to their centroid" in kineFX
so simple setup
I have rig character's eye to eye joints.
Now I want to all points to move towards their centroid, or move towards their mean Z-position. In 3DSMAX you can toggle the "use common centroid" button and then use scale to to pull the vertices together.
But I cannot find a way to do that here. I have to manually move those joints, which is not efficient and of bad quality.
You will need to set a pivot for each point, the viewport tools for kinefx in 19.5 is not all there yet. What you can also do and is more common with a eye rig is to have the center of the eye be a root for all your lid joints, then you can simply rotate the joints. This will look better as well as it will roll over the eye.
here is a basic 5min setup where I just use a skeleton blend to drive a blink.
