Your code changes won't affect the geoset & geostate information created
by the loader so you probably have a model which has been shaded flat in
the tool.

When you <ctrl>g to shade in the tool select dynamic gouraud or just
dynamic depending on the tool and loader version, and make sure you
adjust the tolerances etc to give a smooth appearance.
