hey i've been having issues with this as well. First off how do you view the vertex normals? I know how to view the face normals but I need to see the vertex normals so I can figure out which vertecies are messing up my model shading-wise.
Secondly once I view the vertex normals how do I go about fixing em? My biggest proble is because the vertex normals are all whack the smooth/hard tool never works unless I set vertex normal(using default I have no clue how to use this tool) then I set to face, then I avg normals, then I manually select the faces of the areas I want to work on I set those to face then use the smooth normals tool on that one area. so I have to go about doing this lil by lil and its quite annoying.
any help is much greatly appreciated.
