Hi all, in Part 2 section 3 Quiz and Exercise...on the BaseMesh Class...the add_wireframe_mod() method is reading the wireframe_name attribute, but it always seems to be "None". I added a bunch of print statements to see what was getting passed and everytime it is "None". Even if the mesh already has multiple wireframe modifier on it. BaseMesh class seems to be overwriting the name...so it keeps adding wireframes.
