Apply M FCOV1 Glasses G8 to the scene (not the figure) then parent the glasses to the head and adjust position as needed. The G8.1 glasses are irrevocably hosed, far as I can tell. These glasses are not just props in the normal sense of the word. The glasses are fully rigged as some sort of expressive figure. They have a huge volume of morphs intended to fit many figures and the lenses themselves can be configured to express a range of emotions. Anyway, I did a quick test. The results are imperfect and I did some scale fiddling. The temples would likely need custom morphs to fit properly around the head because there are not wide blocks at the edge of the frames to give the glasses greater overall width.
