This thread was started a long time ago, but every new generation of users runs into this frustration that has not been fixed through the generations of Vicky.

Two quick ways to get rid of those plastic-looking eyebrow shields (and I still don't know why they must be there):

-- In the Material Room, select Eyebrows and make sure Transparency is set to 100%. For some reason this gets reset to 0% when Vicky is made invisible and then visible again.

-- In the Pose Room, select the Eyebrows body part and switch to the Properties tab. Put a check in the Invisible box. This can also be accomplshed in the Hierarchy Editor if you work with that open most of the time.
