I'm doing a retopology of a skull. In some areas, the model appears through the retopology mesh. For this reason, i think i'm making too many faces, so it fits perfectly. Am I doing right? Also, I've read something about baking, and i don't know if it's only for texture.
So, for example: what should i do in that incision?
Notes: subsurf and shrinwrap mods are on
