Male and female base mesh. Designed to have all artists, riggers, animators and texture artists in mind.  It utilises all the major edgeloops needed by animation departments to support systems like FACS or traditional rigging/animation requirements.  Whilst also being super artist friendly with even topology and anatomically based polygroups with realistic proportions that make it easy to sculpt on. Including correctly sized eyeballs with basic eye textures for look development.  It is also super simple to pump out for baking and texturing at multiple resolutions depending on your projects budget with fully optimised UVs, that give you extra resolution where needed.
