Whats a good way to UV map a head, i made a head in blender and when i uvmap it the best way is sphere but its still complicated to make the skins please tell me how you UV map heads!
Try LSCM unwrapping. Take a look at the bottom of the page here
Apply seams to the back of the head, similar to image of that head, then do an LSCM unwrap. You may still have to do some manual tweaking, but it does a really good job.
