Hello.. I have a male model that is in my game. He has around 2,500 polys. When the camera is close to him he looks fine. But as the camera moves away from the model, polygons in his face disappear and holes seem to form in the model. What is the reason for this? I check and all polygons are facing outwards. Again he looks fine close up but when the camera is far from him holes appear in the model, especially around the face. His whole face seems to disappear.

Thanks,
Brad
