I was working on a model in blender and when the model is selected, I know you can hit "W" to bring up another menu with some options. I noticed the "set smooth" option and when I selected it, areas of the model looked nice, but at the same time, a few areas got messed up.
I wanted to know, is using the "set smooth" option something good to use or is it something that should never be selected when creating the models? I just don't know if anyone ever uses it for the models or not.
