This same person also noted that the major problem with the unimesh figures' mesh density (what the hell is mesh density?) is their eyes and mouth parts, which combined have a greater polycount than the rest of the figure. She figure it was an oversight and error on the part of their makers. No, that's intentional. DAZ increased the polycount in those areas that need it most (particularly the face) for better morphing potential. Mesh density generally refers to the polycount or resolution of a mesh. Detailed areas of the mesh need a denser (higher) concentration of polys to define that detail.
