Problem with textures and normals

Ah, yes. As you can see for yourself, your normals are perfectly fine in the last one with the knitted texture. So I’d say terminator problem. Only reasonably to be solved by using softer lighting or finer mesh.

so pretty much an extra level of subsurf if I want the character to work under diverce lighting condicions

Yes.

Still here is an old thread with a little bit of info to be pick up on the matter, if you are interested, although no fix:

thank’s for your time anyway, even if there’s not realy a fix =)
