Each 3D packages have their own tools for dealing with smoothing, be it globally or by using smoothing groups. Normals and doubles were the main obstacles to good smoothing, and now that you know to deal with them, we could proceed with the real topic : smoothing. The Rem Doubles button and the Limit value 3. Of course, using a too high value of Limit could be destructive for the mesh! If you want to lighten the mesh density, please use the Decimate modifier instead, which is safier. Useful to clean meshes, and mandatory when you use most of import scripts with mesh geometry. It defines the distance between two vertices under which they are considered duplicated, and thus, merged. In the Mesh Tools panel, close to the Rem Doubles buttons, there's a parameter called Limit.

Draw Normals shows on your model the normals of the faces Draw VNormals shows on your model the normals at each vertex. Optionally, adjust the size of the normals using the NSize parameter. In Edit mode, panel Mesh Tools 1: activate the Draw Normals and Draw VNormals. In this example, one face of the head of Suzie has its normal inverted, generating the black blotch While they certainly did nothing real wrong, it can be quite frustrating to witness this within their lovely built models. At one point or another, the blenderhead will experience strange dark shading on the surface of their models. This is a very common issue for all beginners involved in modeling. But other cases are quite numerous also, as seasoned poly-modelers could tell you.

Why would you be concerned? You certainly will, anyway, if you decide to model in Blender manufactured, lathed and/or milled objects, e.g., if you are faced with objects with very smooth surfaces but with very sharp edges. It is intended to be short and straight to the point. In this article, we will go through many ways of dealing with smoothing, be it smoothing issues or smoothing strategies.
