My models doesn't look like IntroducingPOD.

Hello everybody. First I want to thank those people who have worked in this amazing SDK. My problem is the following, I’m working on a game app, and are loading my models like in IntroducingPOD example, but my models doesn’t look antialiased like in the IntroducingPOD example. However, when I load my models in the code of IntroducingPOD they looks well. Why is that happening? Thanks in advance.
