if u didnt have that all faces will be smoothed together giving a smooth appearance for everything but sometimes u want to certain creases not get smoothed out (ie give a sharp line between faces)
explained well, no!
ya not bad!..
while modelling, you already tweak the model to get the sharp lines where you want. So, while importing i am getting the triangles, calculating my normals, setting up gourad shading and the lighting should do the rest. right ? . I don’t get it. The What, Why and the How of smoothing. So, i get the face numbers of one smoothing group. what now, I average their normals ??
thanks

You can calculate the right normals for each vertex in your model by using the following algorithm:
The result is that triangles in the same smoothgroup will be shaded, while triangles from different smoothgroups share a sharp edge.
Of course you can put lots of optimizations in step 2. (create as little vertices as possible etc.)
