In the FaceMesh for a Metahuman character, the skeleton tree shows FACIAL_L_EYE and FACIAL_R_EYE which I am assuming corresponds to the eye meshes. My question is that does the FACIAL_L_EyeParallel and FACIAL_R_EyeParallel correspond to the eyeball center? And is there a way to also get the cornea center, iris center, and pupil center from this face mesh?
