Okay so I was practicing to model a human from scratch as a project to finish. Its not really a highly detailed one but I will be adding subsurf after. So this is what it looks like:
So I decided that before applying hair and texture, Is to smoothen the entire mesh. First is I decided to add the subsurface modifier or just smooth edges first.
So I decided to smooth edges first but then something happens:
There seems to be a problem with the edges on the upper lips and the side of the face that only happens on that area along with the rest of the edges connected to it which covers the entire side of the mesh:
This happens whenever I applied to subsurf modifier, and edge smooth option. Is there a specific problem which this is tied to? does this have to do with the vertex or the edges of the affected area?
