Excuse my profound ignorance, but what exactly is a n-gon? Perhaps it's a polygon with more than four points? I will try your suggestion. What bothers me is that it was working good at first and this recently started happening. I can fix the normals, it dose smooth out, but the problem comes back if I close the file. I try exporting it as a Weave Front file and reimporting it. My polygon count went through the roof. But I will try other things. I thought that maybe I was doing something wrong. Thanks for your help.
