I would like to export the from Blender calculated vertex normals into an .obj file. I realized that the amount of vertices in the .obj file does not equal the amount of normals (there are more vertices than vn). I expected that there is a vertex normal for each vertex so there should be the same amount of each.
I guess Blender doesn't export the vertex normals but the face normals and hence there are less normals than vertices. 
Did anyone else experience the same problem and solved it somehow? Is there a way to get the vertex normals into the obj file?
