Finally someone who understands the problem. This is what i was talking about! 🙂 (well, one of the many things)

In short, it bugs me every time that all 3D modeling software screw the face normals of a low poly mesh if we bevel the edges for a better outline; that tiny narrow piece of a face has the same influence on the shared vertices’ normal as the 100 times larger actual face. Grrr. So far didn’t get annoyed enough to implement a fix. So far.
Anyhow, at least i’m not the only one who noticed. 🙂
