Sorry for the noob question, but what's Normal Map? The only thing i know is that it's a pink and green image, that you have to blend to give more detail to your lo poly model. Thx, Rafael.

Normal map = (bit)map that stores normals. (high object) face normals are stored using R,G & B color components = funny colors. There are two kinds or normal maps, tangent space and object space... object space is using "the world" but tangent space uses normals relative to the face = much more useful. Normal maps derived from the same (high) object using Object or Tangent space normals look different because of that.
